Should wp mail work out of the box?

Hi,

Yes, I am running more than 10 websites using EE, and the wp_mail() function does work as it should. Just to be on safe side, I use Postman SMTP to configure the SMTP for outgoing emails.

This way, the emails sent using wp_mail() function does not go to spam folder.

Hope this helps you.
