ErrorCode: '300', Message: 'Email should have either a text/plain
Looking for any assist on this one.
We moved to a new host and now use Postmark for email.
everything is working except our welcome emails wouldn't get sent, so we striped out the src links and we still get an SMTP error:
ErrorCode: '300', Message: 'Email should have either a text/plain or text/html Content-Type or contain a MIME part with one of those content types.'.
