A successful cold email marketing campaign helps businesses reach potential customers who have not interacted with their brand before. Instead of waiting for prospects to discover your product, you proactively contact relevant decision-makers with a personalized message that addresses their business needs.
However, sending cold emails is not as simple as collecting email addresses and writing a sales pitch. You need a clearly defined target audience, reliable email infrastructure, relevant messaging, an appropriate sending schedule, and a process for measuring results.
In this guide, you'll learn how to plan, launch, and optimize a cold email marketing campaign in 2026, including practical examples, email templates, deliverability best practices, and the metrics that matter most.
Whether you're running a B2B sales team, managing a lead generation agency, or building an outbound strategy for your business, this guide will help you create a more structured and measurable campaign. For a deeper look at prospect targeting and outreach strategies, explore our B2B cold email outreach guide.
What Is a Cold Email Marketing Campaign?
A cold email marketing campaign is a structured outreach process in which a business sends unsolicited but relevant emails to prospective customers who have not previously established a relationship with the sender.
The purpose is to start a business conversation, introduce a relevant solution, qualify a potential customer, or generate an opportunity for a sales meeting.
For example, a company that provides cybersecurity services might contact IT directors at mid-sized businesses to discuss their security assessment process.
A cold email marketing campaign typically includes:
Audience targeting: Identifying companies and decision-makers who match your ideal customer profile.
Prospect research: Understanding each prospect's role, company, and potential business challenges.
Email copywriting: Creating concise, relevant messages that explain why you're reaching out.
Campaign sequencing: Scheduling initial emails and appropriate follow-ups.
Email infrastructure: Configuring domains, mailboxes, and authentication.
Performance tracking: Measuring replies, qualified opportunities, meetings, and conversions.
Unlike a newsletter campaign, cold outreach usually targets people who have not opted into your marketing list. That distinction matters because the legal requirements for unsolicited commercial email vary by country and recipient type.
Cold email is most effective when it is relevant, targeted, transparent, and compliant with applicable laws.
Why Run a Cold Email Marketing Campaign?
Cold email can be a useful outbound channel for businesses that sell products or services to other businesses.
1. Reach Decision-Makers Directly
Cold email allows sales teams to contact people who influence purchasing decisions, such as founders, marketing directors, sales leaders, and operations managers.
Instead of waiting for inbound leads, you can proactively identify companies that fit your target market and start relevant conversations.
2. Build a Repeatable Lead Generation Process
A structured campaign gives your team a repeatable process for prospecting, outreach, follow-ups, and lead qualification.
You can identify which industries respond best, which messages generate qualified conversations, and where prospects drop out of the sales process.
3. Personalize Outreach at Scale
Modern outreach platforms let you organize prospect information and personalize messages using company details, job roles, business challenges, and relevant events.
The objective is not to insert someone's first name into hundreds of identical emails. It is to make the message relevant to the recipient's situation.
4. Measure Campaign Performance
Cold email campaigns can be measured using metrics such as delivery rate, bounce rate, positive reply rate, booked meetings, and qualified opportunities.
These metrics help you identify whether the problem lies in your audience, messaging, offer, infrastructure, or follow-up process.
5. Test New Markets and Offers
Cold outreach can help businesses test a new service, enter a different industry, or validate a value proposition before investing heavily in other acquisition channels.
However, results depend on audience quality, market demand, message relevance, and execution. Cold email does not guarantee leads or sales.
How to Plan a Cold Email Marketing Campaign
Before sending your first email, define what you want to achieve and how you'll determine success.
Step 1: Define Your Campaign Goal
Start with one primary objective.
Examples include:
Booking qualified sales meetings.
Generating product demonstrations.
Finding potential channel partners.
Starting conversations with potential customers.
Qualifying companies for an enterprise sales pipeline.
Testing demand for a new product or service.
Avoid trying to achieve every objective in one campaign.
For example, if your goal is to book meetings with B2B software companies, measure qualified meetings rather than focusing exclusively on total replies.
Your campaign goal should determine your audience, offer, messaging, follow-up sequence, and success metrics.
Step 2: Define Your Ideal Customer Profile
An ideal customer profile (ICP) describes the types of companies most likely to benefit from your product or service.
For a B2B campaign, consider:
ICP factor | Example |
Industry | B2B SaaS |
Company size | 50–500 employees |
Geography | United States |
Business model | Subscription software |
Potential need | Increasing qualified sales opportunities |
Buying trigger | Hiring additional sales representatives |
Target departments | Sales and revenue operations |
These criteria are examples, not universal recommendations. Your actual ICP should reflect your product, pricing, customer history, and sales cycle.
A clearly defined ICP prevents you from wasting time contacting companies that are unlikely to become customers.
Step 3: Identify the Right Decision-Makers
After defining your target companies, identify the people most likely to care about your offer.
For example:
Sales software: VP of Sales, Head of Sales Development, or Revenue Operations Director.
Cybersecurity services: IT Director, CISO, or Head of Information Security.
Recruiting services: Head of Talent Acquisition or HR Director.
Email infrastructure: Growth agencies, outbound sales teams, and businesses managing multiple sending mailboxes.
Do not assume that the most senior person is always the best contact. Target the individual who experiences the problem your product solves or influences the purchasing decision.
Step 4: Research Your Prospects
Collect only the information needed to assess relevance and personalize your outreach.
Useful research fields include:
Company name and website.
Prospect name and professional role.
Industry and company size.
Relevant business initiative or challenge.
A credible reason for contacting the prospect.
Verified business contact information.
For example, a company hiring several sales development representatives may be expanding its outbound operation. That could create a relevant reason to discuss a sales enablement product.
However, hiring activity alone does not prove that the company needs your solution. Use research to establish a reasonable connection rather than inventing a business problem.
How to Build a Qualified Prospect List
The quality of your prospect list directly affects the usefulness of your campaign.
A large list filled with irrelevant or invalid contacts can increase bounce rates, generate complaints, waste sales resources, and damage your sending reputation.
Use Reliable Data Sources
Depending on your target market, you can research prospects using:
Company websites and team pages.
Professional networking platforms.
Public business directories.
Industry associations.
Business intelligence and prospecting platforms.
Existing CRM records and previous customer research.
Confirm that the contact's company, role, and business email address are relevant before adding them to your campaign.
Verify Email Addresses
Email verification can help identify invalid, malformed, or potentially risky addresses before sending.
A verification result is not a guarantee that an email will reach the inbox. Some addresses cannot be conclusively classified, and valid addresses can still reject messages.
Use verification as one part of a broader list-quality process.
Segment Your List
Avoid sending the same generic pitch to every prospect.
Create smaller segments based on meaningful differences, such as:
Industry.
Company size.
Job role.
Geographic market.
Business challenge.
Product use case.
Buying trigger.
For example, an email targeting a sales director at a software company should emphasize different outcomes than an email targeting an operations manager at a logistics business.
Best practice: Start with a smaller, carefully researched segment. Review the quality of the responses before expanding the campaign.
How to Set Up Cold Email Infrastructure
Email infrastructure is the technical foundation that allows your campaign to send and receive messages.
Poor configuration can create delivery problems even when your email copy and prospect list are strong.
Before launching a campaign, review your sending domains, mailboxes, authentication records, sending platform, and monitoring process.
1. Choose Your Sending Domains
Your sending domain identifies the domain used in your email address.
For example, a business operating at example.com might use a separate, clearly branded domain for a particular outbound function.
Domain separation can help with operational organization, but it does not guarantee that your primary domain will be protected from reputation problems or that messages from another domain will reach the inbox.
Use domains that accurately represent your business, are configured correctly, and do not mislead recipients about who is contacting them.
Before launching a campaign, build a reliable cold email infrastructure setup with properly configured domains, mailboxes, and authentication records.
2. Configure Business Mailboxes
Create mailboxes for the team members who will send outreach.
Before using them, confirm that:
The mailboxes are provisioned correctly.
Authentication records are configured.
The sending platform supports your mailbox provider.
The accounts can send and receive messages.
Replies are monitored.
Provider-specific sending restrictions are understood.
For businesses using Microsoft 365 mailboxes, review the applicable Microsoft 365 service limits and account policies. For Google Workspace, review Google's current sending requirements and restrictions.
Do not treat a provider's maximum sending limit as a recommended cold email volume.
3. Configure SPF, DKIM, and DMARC
These email authentication mechanisms help receiving systems evaluate whether messages are authorized to use your domain.
SPF (Sender Policy Framework): Specifies which servers are authorized to send email for your domain.
DKIM (DomainKeys Identified Mail): Adds a cryptographic signature that receiving systems can use to verify message integrity and domain authorization.
DMARC (Domain-based Message Authentication, Reporting, and Conformance): Allows domain owners to specify how receivers should handle messages that fail DMARC checks and provides reporting capabilities.
Configure these records correctly for your actual sending setup. A technically incorrect record can create authentication failures, so verify the configuration rather than simply adding records without testing them.
Authentication is essential for a reliable sending setup, but it does not guarantee inbox placement.
Use this email deliverability checklist to review authentication, list quality, bounce rates, and other factors that can affect inbox placement.
4. Choose a Mailbox Infrastructure Provider
Some businesses provision mailboxes directly through Google Workspace or Microsoft 365. Others use a specialized provider to simplify mailbox provisioning and management.
When evaluating a cold email infrastructure provider, consider:
Supported mailbox providers.
Mailbox provisioning and administrative access.
Domain and DNS configuration support.
Authentication setup.
Compatibility with your sending platform.
Pricing and ongoing maintenance.
Support and troubleshooting.
Transparency about service limitations.
Litemail provides mailbox infrastructure for cold email workflows. If you are evaluating infrastructure for outbound campaigns, review the mailbox options and configuration requirements that fit your team's needs.
Remember that infrastructure is only one component of deliverability. Contact relevance, authentication, sending behavior, recipient complaints, and provider policies also matter.
5. Test Before Launching
Before starting a live campaign, send test messages to accounts you control.
Check:
Whether the message is delivered.
Whether SPF, DKIM, and DMARC behave as expected.
Whether links and tracking settings work correctly.
Whether replies reach the intended inbox.
Whether your sending platform records the correct activity.
Whether any unexpected delivery errors occur.
Use these tests to identify configuration problems before contacting real prospects.
How to Write Cold Emails That Generate Replies
A cold email should explain why you're contacting someone, why the message is relevant, and what simple next step you want them to take.
The best message is not necessarily the most creative. It is the one that communicates a credible, relevant reason to start a conversation.
Use a Clear Subject Line
Keep the subject line concise and relevant to the message.
Examples:
Question about your outbound process
Improving sales follow-up
Your team's mailbox setup
Idea for your sales team
Outreach workflow at [Company]
These are starting points, not guaranteed high-performing subject lines. Test them with your audience and avoid misleading claims or artificial urgency.
Personalize the Opening
Show why the recipient is a relevant person to contact.
For example:
"I noticed your team is expanding its outbound sales operation and thought this might be relevant to your mailbox management workflow."
Use a statement like this only when your research supports it.
Avoid superficial personalization that mentions a recent social post or company announcement without connecting it to the reason for your outreach.
Focus on One Business Problem
Do not try to explain every feature of your product in the first email.
Choose one relevant problem and explain how your solution may help.
For example, a mailbox infrastructure provider might discuss simplifying mailbox provisioning and management for teams operating outbound campaigns.
Keep the claim accurate and avoid promising guaranteed deliverability or sales results.
Include One Simple Call to Action
A cold email should have a clear next step.
Examples include:
Would it be useful to compare approaches?
Are you the right person to discuss this?
Would a short overview be helpful?
Is improving this process a priority for your team?
A low-friction question can make it easier for a prospect to respond without committing immediately to a lengthy meeting.
Cold Email Marketing Campaign Examples and Templates
The following templates illustrate different outreach scenarios. Customize each one to your audience, offer, and research before sending.
Template 1: B2B Sales Outreach
Subject: Question about your sales process
Hi [First Name],
I noticed [relevant company-specific observation] and thought I'd reach out.
We help [type of company] with [specific business problem] by [brief explanation of your solution].
Would it be worth exploring whether this could help your team at [Company]?
Best,
[Your Name]
Why it works: It gives the recipient context, explains the relevance of the offer, and ends with a simple question.
Template 2: Cold Email for SaaS Companies
Subject: Idea for [Company]
Hi [First Name],
I saw that [Company] is focused on [relevant initiative].
Teams working on this often need a reliable way to [specific business outcome]. We help with [brief description of your product or service].
Would you be open to a short conversation about how you're currently handling this?
Best,
[Your Name]
Why it works: The message connects the offer to a business initiative rather than listing unrelated product features.
Template 3: Cold Email for Agencies
Subject: Your outbound infrastructure
Hi [First Name],
I work with teams that manage outbound campaigns across multiple mailboxes.
If your agency is spending time provisioning or managing sending infrastructure, [brief description of your service] may be relevant.
Is mailbox management something your team is looking to simplify?
Best,
[Your Name]
Why it works: It targets a specific operational challenge. Use the template only when the offer genuinely addresses that challenge.
Template 4: First Follow-Up
Subject: Re: [Original Subject]
Hi [First Name],
I wanted to follow up on my previous email about [specific topic].
If [business outcome] is a priority for your team, I'd be happy to share a few relevant details.
Would that be useful?
Best,
[Your Name]
Why it works: It reminds the prospect of the original context without repeating the entire pitch.
Template 5: Final Follow-Up
Subject: Should I close the loop?
Hi [First Name],
I'll close the loop after this message.
If [specific problem] becomes a priority later, I'm happy to reconnect.
If it's not relevant, no problem. You can let me know, and I won't follow up again.
Best,
[Your Name]
Why it works: It closes the conversation respectfully and gives the recipient a clear opportunity to decline.
Always honor opt-outs and suppression requests. Do not continue sending follow-ups to someone who has asked you to stop.
How to Build a Cold Email Campaign Sequence
A campaign sequence organizes the initial email and follow-ups into a planned workflow.
A sequence should not be a fixed number of messages sent regardless of recipient behavior. It should stop or change when the prospect replies, opts out, becomes irrelevant, or otherwise should no longer receive outreach.
Here is an example of a short B2B sequence:
Day | Action | Purpose |
Day 1 | Initial email | Introduce a relevant business problem |
Day 4 | First follow-up | Revisit the original question |
Day 8 | Second follow-up | Add a useful detail or alternative perspective |
Day 13 | Final follow-up | Close the conversation politely |
The exact timing is a starting point for testing, not an industry-wide rule.
Make Every Follow-Up Useful
A follow-up should add context or make the next step easier.
For example:
The first follow-up can clarify the original value proposition.
The second can provide a relevant example or answer a likely objection.
The final message can close the conversation without applying pressure.
Avoid sending the same message repeatedly with only the subject line changed.
Stop the Sequence When Appropriate
Configure your campaign workflow to stop when a recipient replies or opts out, where your platform supports these rules.
Also review bounced messages, invalid contacts, and any other conditions that make continued outreach inappropriate.
If a prospect responds positively, move the conversation into your normal qualification and sales process rather than continuing to send automated follow-ups.
How to Choose a Cold Email Sending Schedule
The timing of your emails can affect how recipients experience your outreach, but there is no universally best sending time.
Your audience's location, working patterns, role, industry, and the relevance of your offer all influence performance.
Start With Recipient Business Hours
For a B2B campaign, you might initially test these windows in the recipient's local time:
Sending window | What to test |
8:30–10:30 AM | Early-workday outreach |
10:30 AM–12:00 PM | Late-morning outreach |
1:00–3:00 PM | Afternoon outreach |
3:00–4:30 PM | Late-afternoon outreach |
These windows are experimental starting points. They are not proven to outperform every other time slot.
Segment your campaign by recipient time zone when practical, and compare results across similar audiences.
Manage Sending Volume Carefully
Sending volume should reflect your provider's limits, mailbox configuration, campaign purpose, and observed delivery performance.
Use reasonable sending intervals and avoid sudden, unexplained increases in volume.
A few important principles:
Respect the limits and policies of your mailbox provider.
Monitor bounce rates and delivery errors.
Avoid sending to unverified or poorly targeted lists.
Investigate signs of delivery problems before continuing.
Do not use mailbox rotation or additional domains to evade provider restrictions.
Scale only when your setup, list quality, and campaign performance support it.
Increasing the number of emails does not automatically increase the number of qualified leads. Poorly targeted outreach can create more complaints and delivery problems without producing meaningful business results.
For more guidance on spacing messages across a campaign, see our cold email sending frequency guide
How to Measure Cold Email Campaign Performance
A campaign should be evaluated using metrics that reflect both delivery quality and business outcomes.
1. Delivery Rate
Delivery rate measures the proportion of sent messages that are reported as successfully delivered by your sending system.
A simplified calculation is:
Delivery rate = Delivered emails ÷ Sent emails × 100
Be aware that a delivered email is not necessarily in the inbox. It may be filtered into spam or another folder.
2. Bounce Rate
Bounce rate measures the proportion of sent messages that could not be delivered.
Bounce rate = Bounced emails ÷ Sent emails × 100
Monitor hard bounces carefully. A high or increasing bounce rate may indicate invalid addresses, poor list quality, or other sending issues that need investigation.
3. Reply Rate
Reply rate measures the proportion of recipients who respond to your campaign.
A simplified calculation is:
Reply rate = Unique recipients who replied ÷ Emails delivered × 100
Define the denominator consistently across campaigns. Some tools calculate reply rate using total sent emails instead of delivered emails, so figures may not be directly comparable.
4. Positive Reply Rate
Positive reply rate focuses on responses that indicate genuine interest or a useful next step.
Positive reply rate = Positive replies ÷ Emails delivered × 100
This is often more useful than total reply rate because automated responses, rejections, and opt-outs do not represent sales interest.
5. Meeting Booking Rate
Meeting booking rate measures how effectively a campaign turns outreach into scheduled meetings.
Meeting booking rate = Meetings booked ÷ Emails delivered × 100
You can also calculate meetings per positive reply to understand how effectively your team converts interest into a sales conversation.
6. Conversion Rate
Conversion rate measures the proportion of campaign recipients who complete a defined business outcome, such as becoming a qualified opportunity or customer.
Choose a consistent attribution method so you can compare campaigns fairly.
Example: Evaluating a Campaign
Suppose a campaign sends 1,000 emails and records the following results:
Metric | Example result |
Emails sent | 1,000 |
Emails delivered | 970 |
Bounced emails | 30 |
Unique recipients who replied | 40 |
Positive replies | 15 |
Meetings booked | 8 |
The campaign's delivery rate is 97%, its bounce rate is 3%, its reply rate is approximately 4.1% of delivered emails, and its meeting booking rate is approximately 0.8% of delivered emails.
These figures are illustrative, not industry benchmarks or promises of typical performance.
The next step is to investigate the quality of the replies, the relevance of the meetings, and any delivery issues before deciding whether to change the campaign.
Should You Track Email Open Rates?
Open rates can be misleading because privacy features, image loading, security systems, and email client behavior can affect tracking data.
Treat open rates as a secondary diagnostic rather than your main measure of success.
For most B2B campaigns, qualified replies, booked meetings, conversion outcomes, bounce rates, and complaints provide more useful decision-making signals.
Common Cold Email Marketing Campaign Mistakes
Even a well-planned campaign can underperform if its audience, infrastructure, or messaging is poorly managed.
Targeting Too Broad an Audience
A generic message sent to thousands of unrelated contacts is unlikely to address everyone's needs.
Solution: Segment your prospects using clear ICP criteria and create messaging for each relevant group.
Sending Generic Email Copy
Using the same pitch for every prospect makes your outreach less relevant.
Solution: Personalize the reason for contacting the prospect and connect your offer to a credible business need.
Ignoring Email Authentication
Incorrect or incomplete authentication can create delivery and trust problems.
Solution: Verify SPF, DKIM, and DMARC configuration before launching and investigate authentication failures.
Increasing Volume Too Quickly
Sudden increases in sending activity can trigger provider restrictions or create reputation problems.
Solution: Follow provider requirements, monitor campaign health, and make changes based on evidence rather than arbitrary volume targets.
Sending Too Many Follow-Ups
Repeated messages can annoy recipients and generate complaints.
Solution: Use a limited, relevant sequence, stop when someone replies or opts out, and remove contacts who should no longer receive messages.
Measuring Success by Volume Alone
A campaign can generate many replies without producing qualified opportunities.
Solution: Track positive responses, meetings, qualified leads, and downstream conversions.
Ignoring Legal Requirements
Cold email rules differ across jurisdictions, industries, recipient types, and use cases.
Solution: Determine which laws apply to your recipients and your business. Review applicable consent or other lawful-basis requirements, sender identification, unsubscribe mechanisms, data protection obligations, and suppression procedures before launching.
For example, the United States CAN-SPAM Act, Canada's CASL, and the UK's PECR and UK GDPR can impose different requirements. A business should not assume that a campaign permitted in one country is automatically permitted in another.
Best Cold Email Marketing Tools
The right tools depend on whether you need prospect data, mailbox infrastructure, campaign execution, verification, or reporting.
Instead of choosing a tool based only on its feature list, identify the part of your workflow that currently creates the most friction.
Cold Email Sending Platforms
Campaign platforms help organize sequences, manage sending windows, automate follow-ups, and track responses. Available features vary by provider.
Evaluate platform compatibility with your mailbox provider, campaign controls, reply management, reporting, and suppression handling.
Email Verification Tools
Verification tools help identify invalid or potentially risky addresses before sending. They are useful for improving list hygiene but cannot guarantee deliverability.
Choose a verification process that fits your data sources and risk tolerance.
Mailbox Infrastructure Providers
Mailbox infrastructure providers help businesses provision and manage the accounts used for outbound campaigns.
When evaluating a provider such as Litemail, review its supported mailbox options, provisioning process, administrative access, authentication setup, compatibility with your sending platform, support, and ongoing costs.
A mailbox provider and a campaign sending platform serve related but different purposes. Confirm that the products you select work together as intended.
CRM and Analytics Tools
A CRM helps your team record prospect interactions, manage follow-ups, qualify opportunities, and track pipeline outcomes.
Connect campaign activity to CRM reporting where appropriate so you can understand which campaigns generate business value—not just email responses.

Frequently Asked Questions
What is a cold email marketing campaign?
A cold email marketing campaign is a structured outreach process in which a business contacts relevant prospective customers who have not previously established a relationship with the sender. It typically includes audience research, personalized emails, follow-ups, sending controls, and performance tracking.
How do you create a cold email marketing campaign?
Start by defining your campaign goal and ideal customer profile. Research and verify prospects, configure your email infrastructure, write relevant messages, create a short follow-up sequence, and monitor delivery and business outcomes. Improve the campaign based on qualified replies and other meaningful results.
What is the best cold email marketing campaign strategy?
A strong strategy combines precise targeting, relevant messaging, reliable infrastructure, appropriate sending practices, and consistent measurement. Start with a focused audience segment, test your offer, and prioritize qualified conversations over raw sending volume.
How many emails should you send in a cold email campaign?
There is no universal safe or effective number. Appropriate volume depends on the mailbox provider, account configuration, sending history, campaign design, and applicable restrictions. Follow provider requirements, monitor delivery quality, and avoid sudden increases in sending activity.
How many follow-ups should a cold email campaign include?
A short sequence with an initial email and a small number of relevant follow-ups is a reasonable starting point. The appropriate number depends on your audience and sales cycle. Stop when a recipient replies, opts out, or should otherwise be removed from the sequence.
What is a good cold email reply rate?
There is no single reply-rate benchmark that applies to every campaign. Results vary by industry, audience, offer, data quality, and message relevance. Compare similar campaigns using a consistent calculation, and pay particular attention to positive replies and qualified meetings.
What is the best time to send cold emails?
Start by testing business-hour windows that match recipients' local time zones. Compare results across similar audience segments and use qualified replies, meetings, and delivery metrics to decide which windows work best for your campaign.
Does email warm-up guarantee better deliverability?
No. Warm-up activity does not guarantee inbox placement or protect a domain from reputation problems. Authentication, list quality, sending practices, recipient engagement, complaints, and provider policies all influence delivery outcomes.
Can I run a cold email marketing campaign with Microsoft 365 mailboxes?
Yes, subject to Microsoft's applicable terms, service limits, and account policies. Configure authentication correctly, use a compatible sending platform, and monitor delivery performance. Do not assume that using Microsoft 365 removes the need for responsible sending practices.
Is cold email marketing legal?
It depends on the recipient's location, the type of message, the sender, and the circumstances of the outreach. Review applicable anti-spam, privacy, and marketing laws before launching. Follow the relevant requirements for sender identification, consent or other lawful bases, opt-outs, and personal data handling.
Final Thoughts
A successful cold email marketing campaign starts with the right prospects and a clear reason to contact them. Reliable infrastructure and relevant messaging help you execute the campaign, while thoughtful follow-ups and consistent measurement help you improve it over time.
Start with a focused audience, test a clear offer, and monitor both delivery quality and business outcomes. Avoid scaling simply to increase the number of emails sent.
For businesses using Microsoft 365 or other business mailboxes for outbound sales, mailbox infrastructure is an important part of the overall workflow. Litemail can be considered when evaluating infrastructure options for your cold email operation.
