In case emails are a key part of your e-communication with business colleagues or relatives, it may be better to use an email account with your very own personal domain and a provider that supports the IMAP and POP3 email retrieval protocols, rather than resorting to a web-based email service that entails limitations with regards to the size of the attachments. Thus, you will be able to access your email accounts on any desktop or mobile device using any client software – Thunderbird, Outlook, Apple Mail, and so forth. With the IMAP email protocol, you will be able to see the email messages locally at your end, but they will be on the server at all times, whereas with the POP3 protocol, all email messages will be downloaded onto the device, unless you choose a copy to be stored on the mail server. On top of that, you will be able to use many other valuable options – contact groups, calendars, and so on, not to mention that if there’s a temporary issue with your Internet access, you can still check your email messages since they’ll be on your desktop or handheld device.
