Nearly every signup flow on the internet ends with “check your inbox.” An agent without its own address gets stuck at step 1, or it borrows yours.

AgentMail creates a separate inbox for each agent with one API call, so the agent can sign up for a service and get the confirmation email itself.

Small suppliers, local service firms, accountants and procurement desks run deals, invoices and support through email, and they have no reason to change that.

That is where their 1 billion emails processed number come from, just a year ago, it was 20 million.
