Select your provider?
Our website now provides help and support to customers of Plusnet, Force9 and Free-Online. Please select your provider using the drop-down menu and you will be provided with the technical support details that are appropriate to you.

The screenshots shown here were taken using Windows 7. Although the screen layout will be slightly different, the same steps apply for Thunderbird on Apple OS X and Linux based systems.

Follow these instructions to set up your Plusnet or hosted domain email address.

  1. If this is the first time you've opened Thunderbird, the Mail Account Setup window will appear automatically (continue to step 2).

    Otherwise, go to File on the top bar and select Existing Mail Account...

    Go to File on the top bar and select Mail Account.
  2. Fill in your name, email address and password. If you need help with these, there's more information below the screenshot.

    • Your Name: Enter your full name (or the name you'd like people to see when you send them email from this account)
    • Email Address: Enter the address you're setting up, this could be a Plusnet address (yourname@username.plus.com) or a hosted domain address (yourname@yourdomain.co.uk)

That's all you need to do. If you have any questions about your email service or you experience any problems, please see the Related Articles at the bottom of the page.

Your email username and password

Setting up for the first time?

  • Email username: Your Account username
  • Email password: Your Account password

Your Account username and password are the ones you log in to this website with.

Setting up an additional Plusnet email address?

  • Email username: Your mailbox username (in the format username+mailboxname)
  • Email password: Your mailbox password

If you're not sure what these are, check the email we sent after the new address was created.

Should I choose POP3 or IMAP?

It's up to you! Below are the main differences between the two.

If you're likely to be checking your email from multiple places or devices (e.g. Your computer, a smartphone, webmail while at work), go with IMAP.

If you're only likely to be checking from one machine (e.g. your desktop or laptop at home), go for POP3

POP3 IMAP

Everything sent to your email address is stored on our mail system until you connect and download it with your mail program.

As messages are downloaded to your computer, they are removed from our mail system. After downloading, messages are stored on your computer until you delete them.

With POP3, your messages are kept in one place and you can read messages (that you've already downloaded) when you're not connected to the Internet.

Everything sent to your email address is stored on our mail system until you delete it. For this reason, IMAP is better if you need check your mail from other computers or devices.

Any changes made to your messages (moving them between folders, marking them as read, deleting, etc) will be seen immediately on every computer or device that you check your email with.

As your messages are kept on our mail system, you'll need to be connected to the Internet to read them.
