If you’re using WordPress 5.5, it now uses a new version of the PHPMailer library. We have moved to this new version in 6.2 so it can explain some third party plugins using the deprecated library are failing. Try to reach the “email subscription” plugin author to see if it is overriding the default mailer we use, if so it should update its implementation using the PHPMailer library available in WP 5.5. It can alternatively stop overriding our default mailer.
