SimpleLogin

Free version is too limited. Should add more domains.

Simple and cool. If the UI could be integrated with Proton as soon as possible, it would be perfect.

A versatile service that effortlessly masks email addresses while maintaining control over incoming communications, highly configurable, awesome.

Easy to use and setup. UI could be a bit better, but otherwise a decent service and it's open source.

I've tried a few services that do something like this, but this edged out as the best. It's an idea that expands on the necessity of "throwaway" email for web safety and comfort, and does it very well. Having a unique and permanent email address that can be turned off at any point means customized login information, tracing for the source of spam or phishing, and just good old email organization. Clean but intuitive interface and a great Chrome extension make this idea applicable to the mainstream. I see myself using this for the rest of my Internet life, and have been recommending it to even my tech-averse friends. I see it having good mainstream appeal, especially with such an approachable free tier but valuable paid tier.

Simplelogin is the best email alias out there, because is based in Europe, support PGP and the unlimited bandwidth, you cannot ask for more!!!
