When I write a BT Yahoo email I use enter in order to create a blank line. But when the email is sent, the blanks lines disappear. for example
Hope you have a good day.
All the best"
Any idea why BT Email is removing the blank lines and how I can stop it happening?
I assume you are using webmail. Just tried it and it works fine for me using Firefox and basic view for mail. Try switching to basic view first.
The best option is not to use a web browser for email at all and use a dedicated tool, an mail client.
