apple mail crashing

Try removing the email accounts, then re-add them.

This may sound strange, but if I held down the shift key when opening Mail, it stayed open. But then, if I clicked on the SPAM folder that Spam Sieve uses, it would quit.

I deleted Spam Sieve and the folder, reinstalled Spam Sieve and it works fine now.

After upgrading to 13.2, Mail won't even open. Starts to open, then quits.

Same problem here - deleted preferences and did not fix problem. OSX 13.2 MacBook Pro 2.3 GHz 8-Core Intel Core i9. Mail tries to open and crashes - sent crash report to apple.

Same here. FYI on Studio Mac M1 Ultra

I am having the same issue and I rely on this app for all of my email accounts. It worked great until I updated to Ventura 13.2.
