Mail can be an irreplaceable thing to lose. A Mail.com account can easily be lost through sheer inactivity. This applies to the free Mail.com accounts rather than the paid Premium Service. The free service requires you to sign in once every six months to keep it active. That period is subject to change.

After a certain period of inactivity, a Mail.com account is closed and deleted: all emails contained in it that are not stored elsewhere are irretrievably lost. Of course, you don’t need to send messages from a Mail.com account to keep it, or even receive emails; logging in to the address and account is enough.
A Mail.com account will automatically be closed and emails in it will be deleted after six months of inactivity. This period can be changed. In the past, the period was 12 months. You should check the current Mail.com terms and conditions. The inactivity clause is under 2. Term and Termination, clause 2.4.
If you use Mail.com's Premium Service, you will not be subject to the inactivity termination for the period for which you are paid. However, your account will be reverted to a free account if you do not keep up with your payments or renewals. This can happen if the credit card you have on file for automatic renewals expires or has been reissued and you may have ignored notifications about this. It is easy to get into a vicious cycle of not checking your Mail.com account or any other accounts you have linked to it. When this happens, you may never see the warning about reverting your account to the free version.
