Purelymail comes up in every cost-conscious email discussion, and the reason is obvious: $10 a year for unlimited mailboxes, unlimited custom domains, and unlimited storage is a genuinely remarkable price point. For a solo developer hosting their own domain, or a small team on one or two addresses, that is a hard offer to argue with.

For a 1-10 person MSP billing 20-200 client domains through WHMCS or Blesta, the story becomes more complicated once you look at what $10/year does not include: a provisioning API, a native billing module, per-client isolation, or white-label branding. This guide works through exactly where those gaps sit and what they cost in practice, so you can make a clear decision rather than discover the problems six clients in.

Key Takeaways

Point Detail
Simple plan: $10/year flat No hard limits on users, domains, or storage. A soft limit applies if resource usage significantly exceeds $10/year; at that point you move to advanced usage-based pricing.
No WHMCS or Blesta module Per-client monthly invoicing for individual mailboxes has to be done manually. There is no automated per-mailbox billing connection to your billing platform.
No provisioning API Creating or deleting a mailbox for a client means logging into Purelymail's panel by hand. You cannot trigger it from WHMCS, Blesta, or your own tooling.
No white-label option Clients accessing webmail see Purelymail's interface, not your brand. There is no custom logo, custom domain login, or branded panel.
New ownership since March 2025 Kevin Ryan (Add Rabbit LLC) acquired Purelymail from founder Scott Johnson. The 2026 roadmap includes a billing system redesign; no reseller features are planned.

What Purelymail Is

Purelymail is a small, privacy-focused email host that offers IMAP/SMTP hosting on custom domains at a flat annual rate. It was built by Scott Johnson as a one-person operation and sold to Kevin Ryan of Add Rabbit LLC in March 2025. Under the new ownership the service officially exited beta, and the new owner has committed to keeping prices affordable and maintaining the service's core character.

It supports standard protocols (IMAP, SMTP, CalDAV, CardDAV), custom domains, catch-all addresses, and aliases. Setup is done through a web interface; there is no mobile app and no native desktop client. Deliverability relies on shared sending infrastructure, which is worth keeping in mind for reseller use cases where one misbehaving client can affect others on the same IP pool, a risk explored in more depth in the self-hosted vs managed hosting comparison.

The service's main appeal is price. It is not marketed at resellers, and the feature set reflects that positioning clearly.

The Two Pricing Tiers

Purelymail offers two pricing structures, and understanding both matters before assuming the $10/year number applies to a real reseller workload.

Simple pricing: $10/year. This is the headline number. It comes with no hard limits on users, custom domains, or storage. The fine print is a soft limit: if your actual resource consumption significantly exceeds what $10/year would buy under the advanced rate card, Purelymail asks you to move to advanced pricing. For a handful of light personal mailboxes, you will never hit that ceiling. For a reseller managing 50 active business mailboxes, you almost certainly will.

Advanced pricing: usage-based, billed per resource. The published rate card charges $0.56 per compressed gigabyte of storage per year, $0.23 per 1,000 emails sent externally ($0.03 internally), $0.03 per 1,000 emails received, and a $4/year base account fee. All charges are pro-rated to the byte and the individual message.

The advanced rate is designed to scale with actual usage rather than a fixed seat count. That works well for a predictable single-organization deployment. For a reseller billing individual clients each month at a per-mailbox price, it introduces a structural problem: your cost is usage-driven but your clients expect a fixed monthly line item. We cover that billing mismatch in detail in the next section.

Infrastructure Cost Comparison

To make the cost comparison concrete, here is what 50 mailboxes across 10-15 client domains looks like on each platform. For Purelymail, the estimate uses the advanced rate card with typical business usage assumptions: 4 GB average storage per mailbox (200 GB total), 500 emails received per mailbox per month, and 150 emails sent externally per mailbox per month. These are conservative estimates for active business accounts; heavier users will cost more.

Purelymail advanced pricing (50 mailboxes, estimated) ~$12/mo Atriomail per-mailbox wholesale (50 × $1.39) $69.50/mo $0 $25 $50 $75 $100
Monthly infrastructure cost at 50 mailboxes. Purelymail estimate assumes 4 GB average storage, 500 emails received and 150 sent per mailbox per month using published advanced rate card. Atriomail is the public wholesale price of $1.39/mailbox/month.

Purelymail's infrastructure cost is genuinely lower, and this comparison is meant to be honest about that. The $57/month gap is real. What changes the net economic picture is what Atriomail's higher cost includes that Purelymail's lower cost does not: a WHMCS module that provisions and bills mailboxes automatically, automated SPF/DKIM/DMARC publishing per domain, per-client isolation, and a white-label panel. The next three sections explain what the absence of those things costs an MSP in operational time, and where that changes the total-cost calculation.

The Per-Client Billing Problem

If you run a reseller business, you need to invoice each client individually for their mailboxes every month. Client A has 5 mailboxes. Client B has 12. Client C upgraded from 3 to 5 mailboxes mid-month. Each of those clients expects a line item on their invoice, and they expect it to be accurate to their actual usage for the period.

Purelymail has no concept of per-client accounts or per-mailbox billing. Your entire reseller book lives in one Purelymail account, billed as a single total resource consumption. You pay one bill to Purelymail; your clients each need their own separate invoice from you.

Without a native WHMCS or Blesta module, that means generating each client's invoice manually every month. That is not an insurmountable problem at five clients. At 30 clients it becomes a recurring time cost that eats into the margin that made Purelymail's infrastructure price attractive in the first place. The math behind automated email billing in WHMCS and Blesta assumes a provisioning API on the email side; Purelymail provides neither the API nor the module.

The reason per-mailbox pricing wins for resellers is not just about margins on the cost side; it is about matching the structure of what you sell to what your billing platform can automate. Flat infrastructure cost is easy to absorb in a solo-use scenario. It becomes a manual accounting problem the moment you need to split it across 20 clients and reconcile any changes mid-cycle.

No Provisioning API: Every Mailbox Is Manual

WHMCS and Blesta can automate the lifecycle of a product: create it when a client subscribes, suspend it when an invoice goes unpaid, terminate it when a client cancels. That automation relies on the upstream provider exposing an API that the billing platform can call.

Purelymail has no published provisioning API. There is no endpoint you can call to create a mailbox, change a password, or remove an account. Every one of those actions requires logging into Purelymail's admin panel manually.

For a portfolio of 20-200 client domains, that manual step compounds quickly. A new client onboards: manual mailbox creation. A client adds a team member: manual. A client cancels: manual removal (if you remember to do it). Password reset for a client's user: manual. Compare this to a platform where WHMCS triggers mailbox provisioning in seconds and suspends it automatically on non-payment, as described in the reseller email hosting overview.

The 2026 roadmap published by the new ownership covers a billing system redesign, a website refresh, OAuth authentication, and infrastructure resilience work. A provisioning API is not on that roadmap. This is not a gap that is likely to close in the near term.

No White-Label: Your Clients See Purelymail

When a client logs into webmail, they see whatever interface the underlying provider shows them. On Purelymail, that means Purelymail's branding, not yours. There is no option to add your logo, set a custom login domain like mail.yourclient.com, or present the platform as your own product.

For many MSPs, this is the clearest break point. The entire value proposition of selling email under your own brand, as explained in the white-label email overview, is that the client relationship stays with you rather than with the infrastructure provider. If a client sees Purelymail's name every time they log in, they can eventually bypass you and sign up directly. That is not a theoretical risk; it is a straightforward incentive structure.

A white-label option would require Purelymail to build custom-domain webmail hosting, branded login pages, and the admin infrastructure to manage those customizations per reseller. That is a significant product investment. It is not on the current roadmap.

Ownership, Reliability, and What the Roadmap Says

Purelymail was a one-person project for most of its existence. In March 2025, Kevin Ryan (Add Rabbit LLC) purchased it from founder Scott Johnson, officially exiting beta status. Ryan has committed to maintaining affordability and the service's privacy-first character, and has indicated that any pricing changes will come with advance notice and preferential terms for existing customers.

That is a reasonable set of commitments for a consumer or personal-use service. For an MSP with 30 clients depending on email uptime, a few other questions matter more: Is there a published SLA? What is the support response time for business accounts? What is the redundancy model? Purelymail publishes none of those. The service has improved its infrastructure reliability under the new ownership, but it remains a small operation without the redundancy tier or contractual uptime commitments that larger providers offer.

The 2026 roadmap explicitly notes that the pricing model is being redesigned. The $10/year figure was acknowledged even before the acquisition as potentially unsustainable. Whatever the new pricing looks like, it will not be known until after the billing redesign ships. Building a reseller business on a pricing structure that the provider has flagged as subject to change introduces a margin-planning risk that a fixed per-mailbox wholesale price eliminates.

For comparison, the MXRoute reseller post covers a provider that does publish reseller tiers with defined storage pools and pricing, which illustrates what a more defined reseller-facing model looks like in practice.

When Purelymail Actually Makes Sense

The honest version of this comparison includes the cases where Purelymail is the right call.

  • Your own domain, internal use only. If you need to host email for your own company and have no interest in reselling it, Purelymail's flat rate is genuinely attractive and the operational gaps above do not apply.
  • A single client on a fixed arrangement. If you have one client who never adds mailboxes, never resets passwords, and where you can manage billing outside your standard automation, the infrastructure cost is real.
  • Privacy is the primary requirement. Purelymail's privacy-first model and minimal data collection may be the correct fit for clients where that is a hard requirement, and where the operational trade-offs are acceptable.
  • Extremely light email usage. A domain where users send and receive a few dozen emails a month and store minimal data will stay within the simple pricing tier indefinitely.

What Purelymail is not suited for: a growing portfolio of business email clients who need automated provisioning, per-mailbox invoicing, white-label branding, and a predictable infrastructure cost that maps cleanly to a per-seat price you set in WHMCS or Blesta.

Where Atriomail Fits

The cost gap above is real and this section does not pretend otherwise. Purelymail is cheaper per mailbox and will stay cheaper. What it does not sell you is the reseller layer, and that is the whole difference for a shop billing client domains.

Atriomail answers the three operational gaps this article documented, in order. Per-client billing: the WHMCS and Blesta modules provision and invoice each mailbox against the client record you already keep, so monthly invoicing is not a manual export. Provisioning: a REST API creates, suspends and deletes mailboxes, so it can be triggered from your billing system or your own tooling rather than by hand in a panel. Branding: a white-label add-on puts your webmail domain and logo in front of the client instead of ours, which is a paid add-on on top of the $1.39 per mailbox rate rather than something bundled into it.

Per mailbox that is $1.39 with 15 GB included, unlimited domains, aliases and forwarders, free IMAP migration and automatic SPF, DKIM and DMARC publishing. The pricing page has the full breakdown.

Frequently Asked Questions

Does Purelymail's $10/year cover a reseller with 50 client domains?

Not under the simple pricing tier. The simple plan applies a soft limit when resource usage significantly exceeds $10/year in costs. A reseller with 50 mailboxes averaging 4 GB each generates roughly 200 GB of compressed storage, which would cost around $112/year at the published advanced rate for storage alone. At that scale you would be on the advanced usage-based rate, not the $10 flat. The advanced pricing is still lower than most per-mailbox platforms on infrastructure alone, but the billing and provisioning gaps described above remain regardless of which pricing tier applies.

Can I automate mailbox provisioning from WHMCS with Purelymail?

No. Purelymail has no published REST or SOAP API for account provisioning. WHMCS and Blesta both require an upstream API to automate the create/suspend/terminate lifecycle. Without one, every mailbox action is a manual step in the Purelymail interface. The provisioning gap is independent of the pricing tier and is not on Purelymail's published 2026 roadmap.

Will Purelymail's pricing stay at $10/year?

The new ownership has committed to advance notice for any pricing changes and preferential treatment for existing customers. However, the 2026 roadmap explicitly includes a billing system redesign, and Purelymail's own communications have noted that the $10 rate is not indefinitely sustainable at scale. The timing and shape of any change is unknown. A white-label reseller business built on infrastructure whose pricing is flagged as under review is exposed to margin risk that a fixed per-mailbox wholesale contract eliminates.

Is there a white-label version of Purelymail for resellers?

No. There is no custom branding option, no per-reseller branded webmail login, and no option to present Purelymail's interface under your company's name. The 2026 roadmap does not include any reseller or white-label product development. If client-facing branding matters for your business, a platform built specifically for resellers with a configurable white-label panel is the correct starting point; the Atriomail pricing page covers the per-mailbox wholesale cost and the one-time white-label setup fee.
