There are numerous web-based email providers that you can use, but having an email address with your own domain will give you more credibility if you have a business, for instance, not to mention that with web-based email services there are limits on the maximum size of the attachments that you can send or receive. In case you use an email service that supports the POP3 and IMAP email protocols, you will not have such problems and you will be able to use any software program on your personal computer to access your email accounts, including Outlook, Apple Mail or Thunderbird. You can even set up a mailbox on your mobile phone. The difference between the two email protocols is that with IMAP, an email message is displayed locally at your end, but remains on the email server, whereas with POP3, the message is downloaded to your personal computer, unless you configure the program in such a way as to keep a copy on the server.
