Setting up your email address to an email client

This FAQ will help you to add your email to your favourite email client.

The below instructions will show you how to add your email to your email client. If you need step-by-step instructions, please see the information at the bottom of the page for links to instructions on clients such as Apple Mail and Outlook.

You can use an email program – like Microsoft Outlook, Mozilla Thunderbird, Eudora or Apple Mail – to send and receive email from your 123 Reg mailboxes.

To do this, you need to add a new account to your email program. The exact way of doing this will vary depending on which program you use, but you usually need to find the add new email account option.

Please check the user guide for your email program to find out exactly how to do this – there are links to instructions for the most popular mail programs towards the bottom of this page.

Please note: You will need to decide whether you would like to use the POP3 or IMAP email protocol.

POP3 is the standard protocol for receiving email from a mail server and it allows you to download all of your emails to one location.

IMAP is best if you access your email from multiple locations, clients and devices as it doesn't require downloading of your email content. We recommend using IMAP settings because if anything were to happen to your computer or mobile device, you would still be able to access your emails.

To find out more about the POP3 and IMAP protocols, watch the following support video.

When adding a new email account, you’ll be asked to supply some details. Enter them as follows:

For POP3:

  • Mail account type: POP3
  • Incoming mail server (POP):
  • Outgoing mail server (SMTP):


  • Mail account type: IMAP
  • Incoming mail server (IMAP):
  • Outgoing mail server (SMTP):

When adding a new email account, you’ll be asked to supply some details. Enter them as follows:

  • Username: The username for the mailbox (full email address)
  • Password: The password for the mailbox

Make sure you choose the outgoing mail server requires authentication option.

Once you have entered the details, you can check they are correct by checking the account for email. When you do this, messages should be downloaded into your email program.
