A bit of context: I am a long time user of Proton (5+ years, Unlimited user) services. I am also a long time user of 1Password (since 2016). Understandably I have hundreds of items currently in my 1Password account, and a safe work flow on my devices with that. Would it make sense to start moving those entries to Proton Pass (as it is included) and be off a bit cheaper, or keep them separated as to not throw all the eggs in the Proton basket? Ideas, thoughts, tips or experiences?

I am trying to create a filter within Proton Mail, that adds a label 'mailing list' whenever Proton marks an email as from a mailing list. It doesn't seem so easily possible as far as i can tell and I don't have the time (or will at the moment) to try and create it with a Sieve filter. Is there an easy way to do this?
