If ProtonMail is not functioning as intended and sending emails seems impossible, the following issues may be the cause: server downtime, web browser issues, and account problems. First, visit the Status Proton page at status.proton.me to see if there are any known issues. If the servers are functional, make sure you are accessing the website via one of the accepted browsers, such as Firefox, Chrome, or Safari, and ensure they are fully updated. It may also help to log out and back in after clearing the browser history and cookies.
For mobile phones, make sure you have the most recent installation of the ProtonMail app. Uninstalling and reinstalling the app or switching to the web-based version may suffice for now if the app has issues. Also, rule out a poor internet connection to make troubleshooting easier.
Achieving the required functionality can also be impacted by account issues such as breach of terms or exceeding email storage limits. Check the account settings for messages from ProtonMail regarding any such problems. If the issues are persistent, reach out to the ProtonMail Customer Support Service. Stay focused, and don’t waste time organizing your work while feeling insecure—fix ProtonMail problems yourself or with expert help.
