Protonmail and Gmail both have knowledge bases with articles covering a variety of different topics. If this type of searching is something you use extensively, then you need to consider whether having the extra security is worth more than the missing functionality. This makes the search feature in Protonmail far more limited than in Gmail. In Gmail, you can search old emails by subject line, sender, recipient, date, folder, or contents.ĭue to the encryption process, Protonmail doesn’t index your emails, which means you can’t search for anything in the contents. But while the encryption of your data is great for security, it’s not so good if you want to search for previous emails. As mentioned, Protonmail takes security very seriously. Protonmail comes up short of Gmail in another important area. The lack of a dedicated desktop app is offset by the fact that Protonmail’s web browser user interface is similar to many desktop apps.
