Yes if you need email. Protons encryption keeps others from reading your mail(proton included) and tor keeps your ip from them(anonymous) of course both these could be breached in plenty of ways (using a phone number traceable to you to sign up for proton maybe, using a email name you've used before, etc)
Email is broadly speaking not a very secure communication anyway because it has to somehow identify you to give you messages. But tor + encrypted email attempts to solve both privacy and anonymous better than just email.
Proton has an onion site. Use it for more anonymous access. Still expect a powerful enemy to find you but it'll be harder.
Protonmail+tor?

Deep packet inspection.
Allows them to see you using Tor and block it, but not to connect you to the website you're accessing. It's also circumventable.
