Hey guys and gals,
I've been happily using Proton for nearly a year now and have a referral link. New users get 20 USD off (and I get 20 USD as well - a win-win deal 😎).
Here is the link: pr.tn/ref/30VDKTVQ

If you have any questions, ask away. Also feel free to share this link if you know someone who would benefit.
