Why Look for Proton Mail Alternatives?

Proton Mail is a secure email service known for its strong privacy features, including end-to-end encryption that ensures only the sender and recipient can read the messages.

While Proton Mail offers ample privacy and security features, users may seek alternatives due to several drawbacks that include:

• Its limited search functionality makes finding old emails challenging, especially after a few years.
• Exporting data from Proton Mail can be cumbersome and requires technical skills, leaving paid users feeling “held hostage” until they delete associated data.
• The service also has fewer integrations with third-party apps compared to more mainstream options like Gmail, which limits collaboration and productivity.
• Many advanced features are locked behind paid plans, with the free version imposing restrictions such as a daily email sending limit and reduced storage space.

For those prioritizing such features, these Proton Mail alternatives will give more choices.
