Hello,
Im solving this issue a while now and decited to just ask for help…
I have set up some woocomerce emails in email designer but none of them are sending. I added a SMTP plugin (that usualy do the trick) but the issue still persists.
what do your email conditions look like? Do regular mails from a form for example go out? Do you have any third party plugins enabled that could create a conflict?
If no mails at all go out, not even form a regular form, it’s most likely an issue with the smtp setup.
If it’s only woocommerce emails, try creating a dummy template with just some text and the condition set to all Woo Emails
