I’m more talking global purchases. Just the email will probs be ok but if you purchase using that email and a vpn it raises flags.

Yep, had some dick try to smash into my house. Got a clear look at him and yelled at him in my angry voice and he fucked off. A month later police called me and asked for specific details about his look. I was like wtf? Maybe ask me when you arrived 5 minutes later and not now. I couldn’t remember shit.

I’ll be honest, when it comes to online purchases you may find that a protonmail email will require extra processing/fraud checking due to the amount of fraudsters that use it. Combine that with a vpn and it will just be a pain here and there with online purchases like additional ID verification/delayed orders etc…
