ELI5: Explain Like I'm 5

Pseudonymous remailer

A pseudonymous remailer is like sending a letter without a return address. It's a way to send an email without providing any information that could be used to identify you. It works by taking your message and sending it to a remailer, which then sends it on to its final destination. The remailer uses special software that doesn't reveal any information about you or your message, so the recipient can't trace it back to you. This way, you can keep your identity private and still send emails.
