new email keeps extending off the page - why?

every time I compose a new email, it extends (endlessly) off to the right-hand side... ie a line doesn't drop down after a certain number of characters, it just seems to extend off to infinity.

Does anyone know why, and how to fix?

thanks!

hmmm...

Sounds like an ill formed signature...try removing the sig and compare your results.

Relaunch Mail holding the Shift key down and compare you results...

no insight—

if iCloud Drive is in use—

Quit Mail.

>System Settings>AppleID> > iCloud Drive > Options... > Turn Mail OFF (Important: this is NOT the first Mail you see, in the main iCloud window, this is the Mail in the iCloud Drive options window).

Open Mail.

Make the changes to your email signatures.

Quit Mail to save the changes.

Reopen Mail to check your changes are still there, then quit again.

Finally

System Settings > iCloud > iCloud Drive > Options... > Turn Mail ON (Important: this is NOT the first Mail you see, in the main iCloud window, this is the Mail in the iCloud Drive options window...).

Open Mail and your changes should still be there.
