Where they pull apart

Maildoso

Stands out: MCP at mcp.maildoso.com plus REST so assistants can register domains and create mailboxes.

Watch out: Monthly plans skip domains ($12/year each). Cap is 1,000 mailboxes. A 30-day money-back window is not a trial.

Not the right fit for

  • Buyers who need Google or Microsoft inboxes in the $75 pack
  • Senders who want a free trial rather than money-back

Mailpool

Stands out: Start at one SMTP inbox for $3, with Google at $4 and Microsoft at $5, plus a full API.

Watch out: No free trial. The $3 figure is monthly SMTP; annual SMTP is $2.60. Dedicated IPs start at $200 per server per month.

Not the right fit for

  • Buyers who want a free trial mailbox
  • Teams that only want dedicated IPs under $100
