let’s mail app relies on the inbucket open source project.
“A disposable webmail server (similar to Mailinator)
with built in SMTP, POP3, RESTful servers; no DB required.”

We found the “no-setup” and the “separate mailboxes” features
so easy to use and useful that the solution had to be shared
with all the postmasters’ community.

A dedicated account is available in the RealSender offer:
