POP3 (Post Office Protocol 3) – the most common type of an email account. When using POP3 protocol emails are downloaded to the device (such as a computer or phone) and then deleted from the server.
The main drawback is that by default messages are not stored on the server. Also, sent messages are not saved on the server and they can be seen only on device from which the email was sent. Saving incoming messages on the server and their removal can be configured via mail client.
IMAP (Internet Message Access Protocol) – provides access to e-mail accounts on the server, where they can be stored without downloading to your device (eg computer or mobile phone). Emails can be read from various devices and emails sent from one device, and can be seen in the “Sent” folder of another. This is only possible if the folder “Sent” is synchronized on the server.
When using the IMAP protocol emails are always stored on the server, and as emails backups are made every single night, then emails, if necessary, you later be restored. Restoring from a backup is a paid procedure and for more information, we suggest contacting our support.
