Just awesome!
Not only it works great as a stand alone add on. But it also supported by Protonmail!

Cool and simple hide my email adress, superb

I was a fan of this in Safari/Apple, & this provides even more functionality with the added security of Proton. Dope.

Easy to use and very useful to guard against breaches.

What distinguishes this service is that it offers a multitude of features to users on a free plan. It allows to create multiple aliases, send emails from them and keep them all at one's fingertips with a browser extension. 5 stars.

SimpleLogin is absolutely changing the entire game for email. I wish I knew about this long ago. This has saved me so much time, frustration and solved all the issues I had with email (spam, ease-of-unsubscribing, privacy, organization, etc). If you're debating this extension, stop, and install it now. You will be thrilled. 100 stars out of 5 for me.
