If you would like to send and receive emails, a POP3 account would be the basis for that. We offer different packages with comprehensive features.
Every package comes with POP3 support which is probably the best choice for beginners or persons with moderate requirements. If you realize that a POP3 accounts does not fulfill your needs (any more), you can always switch to an IMAP account.
For businesses or people with higher requirements it is mostly a better choice to combine an IMAP account with your own domain name.
