You could lose all your e-mails
I would have previously given a good rating but please do NOT use mail.com. People - including me - have been unable to log in now for days. There's no way of contacting support, the Facebook page auto responds that they can't fix problems and just directs people to an AI chat that can't help, and comments on the Facebook page about the problem are ignored. And they're clearly seeing the comments as they're posting new things, while just blatantly ignoring people's requests for help. You could lose all your e-mails and e-mail access if you use mail.com so please don't use the website.
