Mailspring is insanely slow on my Mac. I just tried to compose a new message for example and it took a full 30 seconds for the new message window to open. I’m running OS 11.4, Big Sur if that makes any difference.
I find myself using Mac mail again and only suffering through Mailspring when I need to use a template or track an email to see that it was opened.
Any help sincerely appreciated!
