Maildoso is the cheapest mailbox in this market once you buy hundreds. At 1,000 mailboxes each one costs $0.49 a month.
This guide covers the volume tiers, the domain price change, who holds the domains while you subscribe, and the warmup you still have to run.
Maildoso pricing at a glance
The short version before we dig in. Here is what Maildoso pricing looks like on the published tiers:
Confirm the current numbers on the official Maildoso pricing page. Published prices change; the pricing model rarely does.
The Maildoso plans, decoded
Each tier targets a different buyer. Here is what actually changes as you move up:
30 mailboxes ($75/mo)
The minimum order, $2.50 each. At this size Maildoso is not the cheapest option.
300 mailboxes ($225/mo)
$0.75 each. This is where the volume pricing starts to pull away.
1,000 mailboxes ($490/mo)
$0.49 each, the lowest per-mailbox price we found.
Domains
$12 a year, $15 from 1 October 2026. Registered to Maildoso while you subscribe, transferred at the end.
What actually drives the Maildoso bill: volume tiers plus Maildoso-held domains
The meter is mailbox count, with a steep volume curve: 1,000 mailboxes cost less than seven times what 30 do. The price is built for senders running very large fleets.
Domains are the second meter and the one that grows. At 3 mailboxes per domain, 300 mailboxes need 100 domains, which is $1,500 a year at the new $15 price.
The real cost of Maildoso in practice
Sticker prices are the floor, not the ceiling. Here is the realistic annual math for common setups:
Assumes 3 mailboxes per domain at the $15 domain price from 1 October 2026. Warmup is not included and not priced here.
Hidden costs to budget for
Beyond the plan itself, these are the costs that surprise new Maildoso buyers:
- Domain ownership. Domains are registered to Maildoso while you subscribe. They are transferred to you at the end, not before.
- 14 days of warmup. Warmup is not included and 14 days are required before you can send.
- The domain price rise. Domains go from $12 to $15 a year on 1 October 2026, which matters at hundreds of domains.
Is Maildoso worth the price?
If you run hundreds or thousands of mailboxes, warm them yourself and optimise hard for cost per mailbox, Maildoso's volume pricing is the best in the market.
If you need 3 to 30 mailboxes, want the domains in your name from day one, or need to send this week, the low per-mailbox price does not help much.
The pre-warmed alternative: Getlead mailboxes
Maildoso sells mailboxes you still have to warm. Getlead sells mailboxes that are already warm: 4 to 6 weeks of warmup before handover, the domain and admin access transferred to you, and the warmup log handed over so you can audit every day of it.
Maildoso wins on price at volume, clearly. For a fleet of hundreds it is the better buy. Getlead is for a smaller fleet where you want the domain in your name from handover and no 14 day wait before sending.
We plan around 30 sends a day per mailbox and 3 mailboxes per domain. See the packs on the pre-warmed mailboxes page, or compare ten providers in our pre-warmed provider comparison. The head to head is in Getlead vs Maildoso.
