Maildoso alternatives (2026)

Maildoso sells private SMTP inboxes and scores 61, tied for 8th of 52 inbox providers. It takes full marks on buying terms and on API and AI agents, with public prices, a way to try before paying in full, a public API and an official MCP server. The hurdle is getting started. The cheapest plan is $75 a month, the minimum order is 30 inboxes, and Maildoso says it doesn't offer ongoing warm-up in the price, a built-in sequencer or pre-warmed inboxes. Those gaps are the main reasons to compare Maildoso alternatives.

How to choose

Every option here gives something up, so decide first what you can't lose. If you set up inboxes from code or an AI agent, Outreach2day, Icemail and Zapmail confirm an official MCP server; the other five don't state one. If you count on burned inboxes being replaced, as Maildoso confirms, look at MailDeck, Icemail, Zapmail or Hypertide. If you want to try before paying in full, only MailOptimal and SkySenders confirm that. If the $75 entry plan is the problem, Icemail starts at $2.50 a month, Hypertide at $3.30, ScaledMail at $3.75 and MailOptimal at $20 with a 10-inbox minimum. If you need Google Workspace or Microsoft 365 inboxes, which Maildoso doesn't state, MailOptimal, MailDeck, Icemail, Zapmail, Hypertide and ScaledMail confirm both.
