AnonAddy is an open-source anonymous email forwarding service that protects your real email address from spam by using a different unique email alias for every website. It creates unlimited aliases for free. Encrypt forwarded emails with PGP encryption using this service.
ProxiedMail is cheaper in general and offers you a lifetime plan. It's more affordable to get a ProxiedMail lifetime than to have SimpleLogin for a year.
I use this in my personal life to generate different emails for each service I sign up, instead of using the same email whose role is to collect spam lmao.
I also use it when dev-ing to create different sign ins on prod so that emails don't bounce and affect our email deliverability.
I think one thing from me is that when opening my Chrome extension, it takes a while to load the content in it (though its only a minor inconvenience). I think I would also like it if you guys made it so the browser extension has a badge with the number of emails you've created for the website you're currently on.
