In short
- Both let an agent start the sign-up and a person approve it, and both offer an API, an MCP server and a CLI.
- Botmail (launched October 2026, operated by Exon Enterprise LLC) is a lightweight agent mailbox: the agent claims
name@botmail.pro, you approve with one click, and drafts come with a review link you can open without logging in. Paid plans start at $5 a month and allow thousands of sends a day. - Mailly is a fuller email workspace: more free inboxes, SMTP sending, 10 custom domains on its $20 plan, a complete web inbox for people, and templates, contacts, campaigns, workflows and hosted agents.
