I am trying to better understand the entire email, smtp, deliverability topic.
Normally it’s not recommended to just send from WordPress without a proper setup. Emails for contact form notification, order confirmation, .. which are sent from WordPress will very likely end up in spam. It’s recommended to use a proper email service provider (like Postmark for instance)
However, my hosting provider uses outbound filtering through Mailchannels. I just send directly from the server and tested it with [https://www.mail-tester.com/](https://www.mail-tester.com/) and I get incredibly good scores.
Do I still need a proper SMTP setup for those websites? I thought the only reason for it is reliable deliverability, but if the mail-tester is showing good results it’s probably given
