Hi ! It's a long time since I was able to send emails ... they never arrive. Suggestions would be appreciated. I can receive emails - no problem.
If you are a BT Broadband customer has the BT Mail email account been used in the past 150 days?
Why has my email address been suspended or deleted? | Email | BT Help
or
Are you presently a BT Broadband customer or are you paying for your email through a BT Premium email account or did you migrate to EE Broadband?
If none of the above your email account may have been downgraded to a BTMail Basic account which can not be used with an email client or email apps.
