It is possible to replace old e-mail with new in several ways. First, to register the new address of free e-mail and to receive letters from the old address to it. And secondly, to use services of paid services.
Desire to replace the old e-mail address with new can arise if too much spam comes to the first mailbox or you consider that not only you have to it access. Anyway, everything depends on that what services of mail you use - paid or free.
Free mail
The vast majority of people Yandex.Mail, Rambler-Pochta, Mail.ru, Gmail, etc. uses free mailboxes on services. On such services it is impossible to change the login for the registered account. Respectively, it is impossible to replace also the address of mail. Therefore in case of a free mailbox it is necessary only to register the new account with the new e-mail address.
If you want to continue to receive letters which come to an old mailbox, it is possible to configure readdressing of letters. For example, on Yandex.Mail for this purpose it is necessary to visit the Processing Rules of Incoming Mail page and to create the rule of transfer of letters, having specified the address of your new mailbox.
Paid options
Paid options there are two. It is possible to buy own domain and to install the e-mail server. In this case you will have almost not limited freedom in the choice of the new e-mail address. You will be able to select both the name of the domain, and a prefix in the e-mail address. For example, This email address is being protected from spambots. You need JavaScript enabled to view it., This email address is being protected from spambots. You need JavaScript enabled to view it., etc. Minus this option is that you should solve independently all problems connected with the domain and a hosting or to employ for this third-party specialist. But, if you sometime again need to change the old e-mail address for new, you will already make it with ease.
Other option is most convenient. It means use of services of paid services of e-mail. One of such largest international services is FastMail. The cost of service of the account on FastMail begins with 10 dollars a year. You receive a mailbox with the powerful system of fight against spam, smart filters for processing of mail for this money and 250 MB of disk space for storage of letters.
FastMail allows to change once the login (that is a prefix which is written before the icon in the e-mail address). If after that you decide to change the address again, it is necessary to contact support desk.
But not for 10, and for 40 dollars in a year of FastMail allows to use own domain as the e-mail address. For this purpose it is enough to come into the control panel of the domain and to specify there the FastMail DNS servers. Then it will be necessary to specify in settings of FastMail the domain and the new postal address (for example, petrov.ru and This email address is being protected from spambots. You need JavaScript enabled to view it.).
