I’m using Proton with my own domain + calendar + proton pass and I’m quite happy!

Because I was still unsure of it at first, I was using Proton side by side with other services for a while. But I noticed it covered everything I needed with a couple of nice additions.

With email I’m using multiple custom domains plus you can set a catch-all for each. Pass also offers unlimited forwarding emails to avoid spam.

Haven’t really used drive all that much yet, so can’t say anything about it.

Also, supporting a company that depends on neither shareholders or advertisements is a nice change

The german lemmy community seems quite active from what I can tell. Can’t say anything about the EU community as a whole, just created my account 5 minutes ago and I’m still exploring what there is to see.
