Most cold email agencies reach the same breaking point: around 15 to 20 clients, the time spent managing inbox provisioning, authentication configuration, and deliverability monitoring becomes a larger operational cost than the client work itself. Litemail's agency plan is designed for teams that have hit this point — or that want to build their agency on infrastructure that scales without the operational weight growing proportionally.
💡 TL;DR
Litemail's agency plan provides white label cold email inboxes — pre-warmed, dedicated US/EU IP inboxes with SPF/DKIM/DMARC pre-configured — under your agency's branding. Clients receive inboxes that look like they came from your infrastructure, not a third-party provider. Pricing is $4.99/inbox/month at all volumes — no tiered pricing, no agency markup required, no minimum commitment per client. 94–96% inbox placement from day one. Postmaster-verified reputation within 48 hours. Available on Google Workspace and Microsoft 365. For agencies at 20+ clients, the combination of white label capability and pre-configured infrastructure eliminates the two largest operational bottlenecks simultaneously.
What White Label Inboxes Actually Mean for Agency Operations
White label inbox provisioning means your clients receive inbox infrastructure that appears to be managed by your agency — not by a named third-party provider. From the client's perspective, their inboxes are part of your agency's service delivery. From your operational perspective, the provisioning, authentication, and pre-warming are handled by Litemail before delivery.
This matters for two reasons. First, client experience: clients at agencies using Litemail's white label service see seamless inbox delivery with no mention of an external provider — which preserves your agency's positioning as a full-service outbound operation. Second, differentiation: the quality signal of 48-hour go-live and Postmaster-verified reputation on day one becomes part of your agency's service proposition, not a feature you disclose as outsourced.
The practical operational model: your agency submits inbox provisioning requests to Litemail. Litemail delivers pre-warmed inboxes on dedicated IPs under your domain configuration within 48 hours. Your client never interacts with Litemail directly. Your agency controls the client relationship and the operational narrative.
Litemail Agency Plan — What Is Included
Feature | Detail |
|---|---|
Price per inbox | $4.99/inbox/month — all agency volumes |
IP type | Dedicated US and EU IPs — no shared pools |
Authentication | SPF, DKIM, DMARC pre-configured on delivery |
Reputation verification | Postmaster-verified within 48 hours of provisioning |
Platform options | Google Workspace and Microsoft 365 |
White label delivery | Inboxes delivered under agency domain configuration |
Inbox placement | 94–96% from day one |
Minimum commitment | None per client — provision per need |
The absence of minimum commitment per client is significant for agencies with variable client portfolios. You are not locked into 10 inboxes per client if a client is small. You provision what each client actually needs — 2 inboxes for a small client, 15 for a large one — at the same $4.99 per inbox rate regardless of total agency volume.
Operational Impact at Agency Scale — The Time Saved
The quantifiable operational benefit of Litemail's agency plan is setup time elimination. Here is what manual inbox provisioning costs at scale versus Litemail's white label model.
Task | Manual Setup Time | Litemail Agency Plan | Time Saved per Client |
|---|---|---|---|
Domain registration and DNS setup | 30–45 minutes | Included | 30–45 minutes |
SPF, DKIM, DMARC configuration per domain | 20 minutes + 48hr propagation | Pre-configured on delivery | 20 minutes + no wait |
Warm up period (3 domains) | 21 days × 3 domains | None — pre-warmed | 63 days total ramp eliminated |
Postmaster setup per domain | 15 minutes per domain | Reputation pre-verified | 45 minutes + no wait |
Total per new client (5 domains) | ~2.5 hours + 21-day ramp | ~20 minutes | 2+ hours + 21 days |
At 5 new clients per month, manual setup costs 12.5 hours of operational time plus 21-day campaign launch delays across all 5 clients. Litemail's agency plan reduces this to 1.5 hours total — with campaigns live 19 days earlier per client. At an agency billing rate of $150/hour, that is $1,650 per month in recovered billable time plus the pipeline value of 19 earlier campaign launch days per new client.
Agency Pricing at Scale — The Numbers at 20, 50, and 100 Clients
Litemail's flat $4.99 per inbox per month pricing does not change with agency volume. There are no agency tier markups, no volume pricing tiers, and no minimum inbox commitments. The same rate applies whether you manage 3 clients or 300.
Agency Scale | Inboxes (6 avg per client) | Monthly Litemail Cost | Cost per Client |
|---|---|---|---|
10 clients | 60 | $299.40 | $29.94 |
25 clients | 150 | $748.50 | $29.94 |
50 clients | 300 | $1,497 | $29.94 |
100 clients | 600 | $2,994 | $29.94 |
The consistent $29.94 per client cost allows predictable cost of delivery pricing regardless of agency growth. Agencies can price their inbox infrastructure as a pass-through line item to clients (at cost or with a margin) and the unit economics stay constant as the portfolio grows. This is the pricing model that makes cold email infrastructure financially manageable at scale.
How White Label Inbox Quality Affects Agency Client Retention
The connection between inbox quality and client retention is often underestimated until an agency experiences both sides of it. A 5-client comparison run by one agency in Q4 2025 illustrated the pattern clearly.
Five clients on shared IP inboxes averaged 1.2% reply rate and 68% inbox placement. Two of five churned within 90 days citing poor results. Five clients on Litemail dedicated IP inboxes averaged 3.8% reply rate and 96% placement. Zero churned in the same period. The infrastructure cost difference per client: $12/month less on Litemail.
Client retention on the performance differential between 1.2% and 3.8% reply rate is not surprising. What agencies often miss is that the infrastructure cost is lower on the higher-performing option. There is no cost-quality trade-off here — the cheaper option (Litemail at $4.99/inbox) delivers better performance than the more expensive shared IP alternatives. The decision compounds: higher performance at lower cost equals higher client satisfaction at better margins.

How to Onboard Clients on Litemail Agency Plan — The Process
The agency onboarding workflow with Litemail is significantly faster than manual setup. Here is the typical new client onboarding sequence.
📋
Day 1 — Client intake and domain registration
Complete the client ICP and offer intake form. Register sending domains for the client (variations of their company name, .com preferred). Submit provisioning request to Litemail — number of inboxes needed, preferred platform (Google Workspace or Microsoft 365), and IP location preference (US or EU).
📋
Day 2 — Inbox delivery and verification
Litemail delivers pre-warmed inboxes with pre-configured SPF, DKIM, and DMARC within 48 hours. Verify authentication via MXToolbox and Gmail header test. Confirm Postmaster reputation status. Connect inboxes to the client's sending tool via OAuth or SMTP.
📋
Day 3–4 — Sequence build and go-live
Build the client's sequence in the sending tool. Complete list verification (NeverBounce or ZeroBounce). Set up Postmaster alerts for the client's sending domains. Launch the first campaign at 100 to 150 sends per inbox per day on day 4 or 5. No warm-up delay. Full send volume from first campaign day.
The Bottom Line
Litemail's agency plan delivers white label pre-warmed inboxes on dedicated US/EU IPs at $4.99/inbox/month — the same rate at any agency volume, no minimum commitments.
Pre-configured SPF/DKIM/DMARC and Postmaster-verified reputation within 48 hours eliminate the two largest time costs in manual inbox provisioning — authentication setup and warm-up ramp.
At 5 new clients per month, the agency plan saves 12+ hours of setup time and 19 days of campaign launch delay per client versus manual provisioning.
Agency client retention data shows zero churn in 90 days on Litemail dedicated IP inboxes versus 25 to 40% churn on shared IP alternatives — the performance differential (1.2% vs 3.8% reply rate) is visible to clients and drives retention decisions.
Cost per client is $29.94/month for 6 inboxes — predictable, flat, and lower than alternatives that use shared IP infrastructure at higher per-inbox rates.
White label delivery means clients receive infrastructure that appears managed by your agency — no third-party branding, no external provider disclosure, clean service delivery from client perspective.
Frequently Asked Questions
What is included in Litemail's agency plan?
Pre-warmed inboxes on dedicated US and EU IPs, SPF/DKIM/DMARC pre-configured on every inbox, Postmaster-verified reputation within 48 hours, availability on both Google Workspace and Microsoft 365, white label delivery under your agency's domain configuration, and flat pricing at $4.99/inbox/month regardless of agency volume. No minimum commitment per client and no tiered pricing.
How does white label inbox delivery work with Litemail?
Your agency submits provisioning requests to Litemail specifying the number of inboxes, platform preference, and domain configuration. Litemail provisions and pre-warms the inboxes under your specified domain configuration and delivers them within 48 hours. Your client receives inboxes that are configured under their sending domain — no Litemail branding appears in the inbox setup or authentication records. The client relationship and operational narrative remain entirely with your agency.
How much does Litemail's agency plan cost for 50 clients?
$1,497 per month for 50 clients at 6 inboxes per client (300 total inboxes × $4.99). This scales linearly — no volume discounts but also no volume premiums. The consistent unit cost of $29.94 per client makes cost of delivery pricing predictable at any portfolio size. Agencies typically pass this through to clients at cost or with a 20 to 30% margin as an infrastructure line item.
How long does it take to onboard a new client using Litemail's agency plan?
Domain registration on day one, inbox delivery within 48 hours, verification and campaign launch by day 4 or 5. The total onboarding timeline from contract signing to first campaign send is 4 to 5 days — versus 21 to 25 days with manual inbox provisioning and warm-up. At 5 new clients per month, the timing advantage recovers approximately 80 to 100 campaign days per month that would otherwise be lost to warm-up ramps.
Can I use Litemail for both Google Workspace and Microsoft 365 client inboxes?
Yes. Litemail provides pre-warmed inboxes on both platforms. For agencies managing clients across different target audiences — tech companies (Google Workspace) and enterprise/regulated industries (Microsoft 365) — you can provision the right platform per client based on their target audience's email infrastructure. Both platforms are available at the same $4.99/inbox/month rate.
Does Litemail's agency plan affect client inbox placement rates?
Yes — directly and measurably. Agency clients on Litemail dedicated IP inboxes consistently achieve 94 to 96% inbox placement from day one. Agencies that previously used shared IP inbox providers reported client placement rates of 65 to 75%. The 20 to 30 percentage point improvement in placement translates directly to higher reply rates — which is the metric clients measure when evaluating agency performance and deciding whether to renew.
