How to choose
Choose Gmail if you need pooled storage (30 GB on entry plan) for Drive and Photos, but pick Outlook if you need a dedicated 100 GB mailbox limit on paid plans.
Select Proton Mail for zero-access, end-to-end encryption under Swiss law, whereas Gmail and Outlook rely on standard TLS and server-side encryption at rest.
Gmail and Outlook support IMAP/POP natively, but Proton Mail requires the paid Proton Mail Bridge service to connect to third-party desktop clients.
Gmail ties users to the Google ecosystem with shared storage, while Outlook integrates deeply with Microsoft 365 and Windows, making migration costs a key consideration.
Our verdict
Gmail remains the best overall email service for most users due to its 30 GB pooled storage and seamless Google ecosystem integration, while Proton Mail is the definitive choice for those prioritizing zero-access encryption.
