Em@il for AI agents.

Your agents need email addresses. Other services charge $6/user/month per mailbox. We charge nothing for the first inbox and $5/month for a custom domain.

Send and read emails with a simple REST API. Built for agents, not humans.
Absurdly cheap
Free inbox on our domain. $5/mo for your own custom domain with unlimited mailboxes.

Full IMAP access. SPF, DKIM, DMARC. Your agent's emails land in inboxes, not spam.
