Hi,

I really appreciate the ability to mute or block individual senders for a given alias in SimpleLogin, it's incredibly useful. I’d love to see a complementary feature: the ability to whitelist specific senders instead.

Specifically, it would be great to have a "whitelist mode" toggle for aliases, where all incoming messages are muted or blocked by default, and only explicitly whitelisted addresses are allowed through, mirroring the current muting functionality, but in reverse.

By the way, I think SimpleLogin is absolutely fantastic. It has completely transformed how I manage my digital life across email, newsletters, apps, and beyond. Huge thanks to the team!

Best,
Colin
