Mail service is the best way of communication for many different occasions. It has been the oldest mode for transferring messages. There are other options too, but email is the standard form. Now when a user is using an email service to transfer mail, ProtonMail users are not able to send any mail from their account. Even after composing and sending the mail, receivers claim that no mail has been delivered. To fix the sent mail issues follow the given points below.
• Time and date of the device should be set to the default time zone.
• No internet connection in the system does cause such issues.
• If the email address of the receivers is entered is a mistake.
• Account holders making some changes in the settings can cause issues.
Check the points one by one and ensure the reason for mails not being sent. If further support is required than ProtonMail Technical Support is always at service for users.
