Can you explain how the backend works? Will it block Apple's 'hide my email' feature from functioning with valid @icloud.com addresses, or similar 'valid' domains with potentially disposable email addresses?

(not OP) No, but you can block those with a regex pretty easily.

Developers and regex on email is always a terrible idea. So many fail to understand what the RFC allows (virtually anything). Can't tell you how often websites will reject an email address with a two-character localpart :-(

Yeah I can relate to that... some don't even realize TLDs longer than 3 chars exist (my primary domain uses a 4 char TLD)

Anyway, sometimes it's better to write a blog post about an intersting problem you solved to build your project, but it's important that it's interesting.

Great domain name. This is already a crowded market. Do you undertake to not store email addresses tested?

Just updated! We don't need your full email address as input, now instead, we only accept your target domain name.
