Back in 2010 I had an idea for a service that would allow people to easily create semi-permanent email aliases so that they could give an email address to people and websites without revealing their real email address. These aliases will continue to work indefinitely unless you choose to block them. My brother and I spent a few months building the initial version and launched the website in July 2010. For the first year we had about 50 signups per month, by 2013 this had increased to 1500 and it's currently around 3500 per month. Similarly, our revenue grew consistently but slowly - doubling…

I kept running into the same problem while building AI agents: every agent that needs email ends up sharing my personal inbox or a single company domain. That breaks attribution, creates deliverability risk, and makes it impossible to test sender identities per agent. So I built AgentMailr. You call an API to create an inbox, your agent gets a unique email address, and replies route back to that specific agent. Works for both inbound (OTP parsing, reply routing) and outbound (cold email, notifications). Bring your own domain is supported so emails come from your domain, not ours. REST API…
