In Beta 11 takes a minimum of two minutes to send out any email. This is on Mac OS Tahoe 26.6.2. It shows the message: Composing Message, this operation may take a while to complete as in the attached screenshot.
In the production version of eM Client I do not have this issue.
Check that you have the latest Beta v11.0.196 via the release history page.incase you have an older Beta.
If you already have, then could be the mail is possibly still synching mail or locally caching mail so taking a very long time to send mail.
To check if it is, “click the dropdown on the right of Refresh” and click “Show Operations”.
Tehere is a tool Profile for 10 seconds in menu that should help us disgnose the problem.
