Better use an another free mail provider, as this has some serious issues. The worst thing they will do to your mail is block it for no apparent reason. Which is very bad if you had your email for business. Secondly, you will get a ton of spam emails in your main inbox folder, but in spam folder there will be zero of them. Is spam filter even working ? Thirdly occasionally i can't receive any of emails that were sent to me.
Actually there are a huge amount of problems with mail.com and this problems will only affect you, so as other reviews, i will say stay away from them.
