Mull is a great choice imo. You can get it from f-droid after you’ve added the DivestOS repositary. It’s basically a deblobbed Firefox built with privacy in mind.

Edit: just rember to add ublock origin to block adds.

Simplelogin is slow with a premium account as well. Sometimes it’s forwarded in just a few minutes, other times it takes way longer. This is sometimes a problem when signing up for something and you need to confirm your email to activate your account.

Replying on Simplelogin is a hit or miss in my experience. Sometimes it just doesn’t work and my email never reach the reciever. It’s also kind of slow as there is a (sometimes long) delay before I get my mails. It’s good enough for subscriptions and shopping online, but hopeless in two way communications. Waiting for confirmation emails is a pita because of the delay of the service. I’m curious if anonaddy is faster than Simplelogin?
