TrulyInbox built its entire product pitch around fixing the one thing that makes warmup tools financially unworkable at scale: per-inbox pricing. Most competitors charge $19–$29/inbox/month. At 10 inboxes, that's $190–$290/month — just for warmup, before inbox cost or campaign platform fees. TrulyInbox's unlimited-inbox plans change that math significantly. One G2 reviewer reported deliverability jumping from 40% to 91% in under a week. A Trustpilot rating of 4.3/5 across real users suggests the product works. But there are specific situations where it doesn't — and those are what most TrulyInbox reviews don't cover. Here's the honest version.
TL;DR
💡 TL;DR
TrulyInbox is the best-value warmup tool for operations running 5+ inboxes — unlimited accounts on paid plans ($29–$79/month) makes it 50–80% cheaper than per-inbox competitors at scale. Deliverability results: ~90–92% inbox placement after 3–4 weeks per user testing. Limitations: no per-ISP breakdown, results plateau over time for some users, 6–10 week warmup timeline is unchanged. Alternative that skips warmup entirely: Litemail pre-warmed inboxes at $4.99/inbox, 94–96% placement from day one, no warmup tool subscription needed.
TrulyInbox Pros and Cons
Pros
Unlimited inboxes on paid plans make TrulyInbox one of the most affordable warm-up tools for agencies and multi-inbox operations.
Free forever plan available for testing a single inbox.
Simple OAuth setup with Google Workspace and Microsoft 365.
Custom warm-up settings on higher-tier plans.
Strong value for businesses managing 5+ inboxes.
Cons
No inbox placement testing by provider (Gmail vs Outlook vs Yahoo).

New domains still require 6–10 weeks of warm-up.

Warm-up alone cannot solve SPF, DKIM, DMARC, or content-related deliverability issues.
TrulyInbox Reviews: What Do Customers Say on G2 and Trustpilot?
Before choosing an email warm-up tool, it helps to look beyond the product's advertised features and understand what actual customers report.
TrulyInbox has customer reviews on both G2 and Trustpilot. The feedback provides useful insight into its usability, pricing, warm-up experience, and areas where the platform could improve.
TrulyInbox Reviews on Trustpilot
TrulyInbox has a 4.3/5 TrustScore on Trustpilot, with 87 reviews listed at the time of checking.
Positive reviews frequently mention the platform's straightforward setup, simple interface, and value for money. Some users report improvements in email deliverability after using the warm-up feature.
However, feedback is not uniformly positive. Some reviewers raise concerns about support responsiveness, subscription limitations, or inconsistent deliverability results. These experiences suggest that buyers should evaluate their own mailbox performance rather than assume warm-up will produce the same results for every account.

TrulyInbox Reviews on G2
TrulyInbox also has a 4.3/5 rating on G2, with 54 reviews listed at the time of checking.
Reviewers commonly highlight its easy onboarding process, automated mailbox warm-up, and ability to run in the background without constant manual management.
The feedback also identifies areas for improvement. Some users would like more detailed reporting, additional control over warm-up settings, or more affordable options for smaller teams.
These reviews suggest that TrulyInbox may be a practical choice for teams looking for accessible, automated warm-up. However, businesses that need extensive diagnostics or advanced reporting should evaluate those requirements before subscribing.

What Do These Reviews Mean for Potential Buyers?
The overall feedback points to three considerations:
Ease of use: Straightforward setup and automation are recurring positives.
Value for money: The pricing model can be attractive for teams managing multiple mailboxes, depending on their daily warm-up requirements.
Reporting and deliverability: Users should assess whether the available insights meet their needs and independently monitor actual inbox placement.
Customer ratings are useful signals, but they do not guarantee that a warm-up tool will improve every sender's reputation. Results depend on factors such as mailbox configuration, sending practices, recipient engagement, list quality, and domain reputation.
For that reason, consider customer reviews alongside a hands-on trial, current pricing, and your own deliverability measurements.
What TrulyInbox Actually Does
TrulyInbox is a dedicated email warmup tool — not an outreach platform, not a deliverability diagnostic. It does one thing: connects to your inboxes and runs automated warmup activity to build sender reputation with Gmail and Outlook.
The warmup mechanism: TrulyInbox sends emails from your connected accounts to other accounts in its warmup network. Those accounts open the emails, reply, move them out of spam, and mark them as important. This simulates genuine engagement and signals to Gmail and Outlook that your inbox generates positive recipient interactions — the core input to sender reputation scoring.
What's genuinely useful about TrulyInbox specifically:
Unlimited inboxes on paid plans. This is TrulyInbox's actual competitive advantage. $29/month covers unlimited accounts on the base plan. At 15 inboxes, you're paying $1.93/inbox/month for warmup versus $19.50–$29/inbox at MailReach or Lemwarm.
Customizable warmup parameters. Starting volume (recommended: 25/day), reply rate (up to 65%), ramp-up speed (3 emails/day increase), max daily volume — all adjustable.
Works with GWS and MS365. Both platforms connect without compatibility issues. Setup is OAuth-based and takes minutes per account.
Free-forever plan. One inbox, limited volume. Genuine free tier for single-account evaluation.
Who Should Use TrulyInbox?
TrulyInbox is best suited for:
Cold email agencies managing multiple inboxes
Sales teams running Google Workspace or Microsoft 365
Businesses looking for affordable unlimited warm-up
Teams rewarming existing domains
Users wanting a simple warm-up solution without advanced deliverability tools
Who Should Avoid TrulyInbox?
TrulyInbox may not be the best choice if you:
Need inbox placement testing across multiple providers
Want advanced deliverability diagnostics
Require detailed ISP-level reporting
Need enterprise-level monitoring and alerts
Want inboxes ready immediately without a warm-up period
Deliverability Results: Real Numbers
The marketing claim from TrulyInbox is 95%+ inbox placement. Independent results paint a more nuanced picture:
Source | Result | Timeline |
|---|---|---|
Saleshandy independent review | ~90% after 3–4 weeks | New accounts |
G2 reviewer | 40% → 91% in under 1 week | Established domain re-warm |
Trustpilot users (multiple) | Measurable improvement within days | Varies by domain age |
Skylead independent test | 90–92% range | 4–6 weeks new domain |
Litemail pre-warmed (comparison) | 94–96% | Day 1 |
The 90–92% range in independent testing is genuine — TrulyInbox works. But "works" still means 6–10 weeks of warmup before campaign-ready status, and results plateau over time for some users, particularly high-volume senders who push the warmup network's capacity.
Limitations Most Reviews Skip
No per-ISP deliverability breakdown. TrulyInbox shows aggregate placement metrics — not placement by Gmail, Outlook, Yahoo separately. If your deliverability problem is specific to Outlook recipients, TrulyInbox's dashboard won't identify that. MailReach provides per-ISP breakdown; TrulyInbox doesn't.
Results plateau at high volume. Some high-volume users report that deliverability improvements level off after 6–8 weeks rather than continuing to improve. This is likely a warmup network quality ceiling — the engagement signals become somewhat predictable to Gmail's filters over time.
Basic tier has real limitations. Customization of warmup parameters (reply rate, sending volume, schedule) requires the Growth plan or higher. The Starter plan's default settings are adequate for basic warmup but don't give you the control to optimize for specific problem inboxes.
Still takes 6–10 weeks. TrulyInbox is faster than some competitors for established domain re-warming, but new domains still require 8–12 weeks minimum. There's no tool that makes genuine sender reputation build faster — the timeline is set by Gmail and Outlook's scoring model, not the warmup tool.
Who TrulyInbox Is Right For
TrulyInbox is genuinely the best choice in specific situations:
5+ inboxes on a budget: The unlimited-inbox flat rate makes it the most cost-effective warmup tool at scale. At 20 inboxes, $29/month versus $390–580/month from per-inbox competitors.
Re-warming established domains: For domains that already have some sending history, TrulyInbox can accelerate reputation recovery from Medium to Good faster than tools optimized for new domain cold starts.
Teams using Saleshandy: TrulyInbox is included in Saleshandy's paid cold email plans — making it a bundled zero-additional-cost option for existing Saleshandy users.
TrulyInbox is not the right choice if you need inboxes campaign-ready in under 6 weeks, require per-ISP diagnostic data, or run more than 30–40 inboxes where network quality limitations become more pronounced.

Frequently Asked Questions
Is TrulyInbox worth it in 2026?
Yes, for the right situation. TrulyInbox's unlimited-inbox flat-rate pricing makes it the best-value warmup tool for operations with 5+ inboxes — 50–80% cheaper than per-inbox competitors at scale. Independent testing confirms ~90–92% placement results. It's not worth it if you need inboxes campaign-ready in under 6 weeks, require per-ISP diagnostic data, or have a single inbox that would be more cost-effectively served by TrulyInbox's free-forever plan.
How long does TrulyInbox take to warm up a new inbox?
3–4 weeks for established domains being re-warmed (reaching ~90% placement). 8–12 weeks for brand new domains starting from zero. The timeline is set by Gmail and Outlook's sender reputation scoring model — no warmup tool, including TrulyInbox, can significantly accelerate this. Pre-warmed inboxes from Litemail bypass the timeline entirely: Good/High Postmaster reputation pre-established before delivery.
What is TrulyInbox's pricing in 2026?
TrulyInbox pricing in 2026: free forever (1 inbox, limited volume), Starter plan ($29/month, unlimited inboxes with basic features), Growth plan ($79/month, unlimited inboxes with full customization including reply rate and volume controls). Ultra Premium Warmup is a $59/month add-on available on paid plans. The unlimited-inbox structure makes it significantly cheaper than per-inbox tools at 5+ inboxes.
How does TrulyInbox compare to MailReach?
TrulyInbox ($29–$79/month flat rate) is significantly cheaper than MailReach ($19.50/inbox/month) at 5+ inboxes. MailReach wins on diagnostic depth — per-ISP placement breakdown is something TrulyInbox doesn't offer. MailReach scored 93% in Skylead's test versus TrulyInbox's 90–92% in independent testing. For budget-focused operations, TrulyInbox. For diagnostic visibility, MailReach. For skipping warmup entirely, Litemail pre-warmed inboxes at $4.99/inbox.
Does TrulyInbox work with Google Workspace and Microsoft 365?
Yes. TrulyInbox connects to both Google Workspace and Microsoft 365 accounts via OAuth. Setup takes minutes per account. The warmup mechanism works on both platforms, and TrulyInbox's dashboard tracks warmup progress for both GWS and MS365 inboxes simultaneously.
What's the best alternative to TrulyInbox in 2026?
Depends on the use case. For more diagnostic data: MailReach at $19.50/inbox. For free single-inbox: TrulyInbox's own free plan. For skipping warmup entirely and sending at 94–96% placement from day one: Litemail pre-warmed inboxes at $4.99/inbox — no warmup tool subscription, no 6–10 week wait, higher placement rates than TrulyInbox's 90–92%.
Does TrulyInbox have a free plan?
Yes. TrulyInbox offers a free forever plan for one inbox with limited daily warm-up activity. It's useful for testing the platform before upgrading to a paid plan.
Is TrulyInbox good for agencies?
Yes. TrulyInbox is particularly attractive for agencies managing multiple client inboxes because its paid plans support unlimited inboxes, reducing costs compared with per-mailbox pricing models.
Can TrulyInbox replace inbox placement testing?
No. TrulyInbox focuses on email warm-up. Businesses that need inbox placement testing and detailed deliverability diagnostics may require an additional deliverability platform.
Is TrulyInbox safe to use?
Yes, when used alongside proper email authentication (SPF, DKIM, and DMARC) and responsible sending practices. Warm-up improves sender reputation but does not guarantee inbox placement.
What do users say in TrulyInbox reviews?
Most TrulyInbox reviews highlight its affordable unlimited-inbox pricing, simple setup, and ease of use for email warm-up. Positive feedback often focuses on value for agencies and sales teams managing multiple inboxes, while common criticisms mention limited deliverability diagnostics and basic reporting compared with more advanced deliverability platforms.
