Burner addresses you can still read.
Every alias service hides your real address. This one also lets your assistant read what arrives at the alias, which no other alias service will do.
You already know the drill. A site wants an email, you do not want to give it yours, so you make a masked address. Then the mail goes somewhere awkward and you either forward it back into the inbox you were protecting or you never read it.
Echos aliases are readable. The mail stays in a mailbox that holds nothing else, and Claude can search it, pull out the code, and tell you what the site actually sent.
Make as many as you want on any plan, including free. One per site if you feel like it. When a site sells your address, you know exactly which one did it, and you disable that alias alone.
We checked this in September 2026 against Apple Hide My Email, SimpleLogin, addy.io, Firefox Relay, DuckDuckGo Email Protection and Fastmail. None of them offer an agent a way to read message content. addy.io has the best API of the group and excludes message reading on purpose.
