Choosing an email provider is a long-term commitment. When comparing services like Gmail vs. Outlook or looking for secure alternatives like Proton Mail, consider what matters most to you.
If you need anonymity, look for "End-to-End Encryption" (E2EE). Services like Tuta and Proton are leaders in this space, often hosted in countries with strong privacy laws like Switzerland or Germany.
Running out of space is annoying. Yahoo Mail offers a massive 1TB of free storage, while GMX offers unlimited email archiving. For document heavy users, Gmail's 15GB (shared with Drive) is the industry standard.
