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

What we noted

Domains extra on monthly plans
15 cold emails per mailbox per day
No free trial, only money-back

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

Worth keeping in mind: MCP at mcp.maildoso.com plus REST so assistants can register domains and create mailboxes.
