Secure email communication facilitates safe financial exchanges and enhances data privacy

Pros

"The auto encryption of attachments is valuable."

Cons

"One improvement could be the integration between ProtonMail and Proton Pass, allowing sharing of specific secrets via email. "

What is our primary use case?

I use ProtonMail for exchanging invoicing with clients, managing financial information, and receiving notifications from bank accounts and investment brokers. It's dedicated to high-importance communication involving financial information.

What is most valuable?

The auto encryption of attachments is valuable. ProtonMail allows me to provide my own hashing algorithm, which is beneficial for those familiar with encryption. It’s clear about its processes. While Gmail offers similar features, ProtonMail is distinct regarding attachments, making it preferable for critical information.
