Add a custom domain mail to Gmail

Gmail, is one of the most popular email management platforms. Partly because you can link and manage an existing email address in Gmail. This works similarly to applications such as Microsoft Outlook & Mozilla Thunderbird to name a few.

This can be very powerful if used correctly. For instance, adding an email account to Gmail enables access to some of Gmail’s features, including:

  • Multiplatform Support – A web-based app, an iOS app, and an Android app.
  • In-built email forwarding support.
  • A search feature that is both quick and reliable.
  • Support for multiple mailboxes or email accounts.
  • Ability to move and manage mail in the user-friendly Gmail interface (Filtering, Tagging Mail)

POP3 and its Limitations

POP3 or Post Office Protocol version 3 is an email protocol used to retrieve emails remotely from a hosted mail server; in this case, your hosting package. By internet standards, POP3 is fairly old, the first version being released in 1984, it has undergone 3 different versions since. However, POP3 remains popular due to its compatibility with most mail software natively supporting popular applications such as Microsoft Outlook, Gmail, and Mozilla Thunderbird.

This compatibility comes from the inherent simplicity of POP3, allowing easy configuration, operation, and maintenance of enabled systems. However, POP3 has limitations and these are most apparent when compared to IMAP, which mirrors emails across devices rather than downloading the email for use on one device.

Before you can add an email to Gmail, create an email using your custom domain. Afterwards, start reaping the benefits of using your custom domain email in Gmail.
