I have recently signed up to BT for internet, broadband and phone. How do i go about setting up a BT email address?
BT stopped email addresses for new customers a while ago
Why on earth would you want an email address tied to an ISP?
As has been mentioned, BT stopped email for new customers in 2022
See link.
You can get a free email service from Google gmail or Microsoft Outlook.com and there are many other free email services if you do an Internet search.
