I’d like to know, how I get The Newsletter Plugin to use WP Mail SMTP for sending E-Mails.
I already setup WP Mail SMTP and it’s working like a dream
I set “Enable the SMTP?” to “No” in the Newsletter Plugin
When I send a test E-Mail from WP Mail SMTP it works perfektly and I get 3x PASS for SPF, DKIM and DMARC, when I send a test E-Mail from the Newsletter Plugin it works, but I get only 2x PASS, the receiver gets a SPF Softfail. So I guess the Newsletter Plugin is not using WP Mail SMTP.
What do I need to do for The Newsletter Plugin to use WP Mail SMTP?
