AdGuard Temp Mail’s addresses are temporary and aren’t stored long by design:
Emails are automatically deleted 24 hours after you receive them.
A temporary mailbox is deleted after 7 days of inactivity. But if you keep the page open or come back in a couple of days, it won’t disappear.
AdGuard Temp Mail is currently in beta stage. Here’s what we’re planning to add in the future:
Zero-access encryption
TLS support on the SMTP server side
Image proxying
Security checks for links

It’s similar. I made it to solve my spam problem, but it’s also really good for staying organized. When you sign up for something, you can use yourname-whatever@port87.com, then if you don’t want it anymore, you can block that address. Each address has its own label in your account, and blocking the address is just one click.
