Hi, @adleyho!
Thanks for getting in touch, and we’re sorry for the trouble.
Please note, that the WP Mail SMTP plugin is responsible for sending emails from your website. Our plugin routes all emails to the mailing service (chosen mailer), and the mailing service is responsible for the email receiving.
So, the WP Mail SMTP plugin just bridges a connection between your WordPress site and your email mailing service (mailer).
For example, you have a form on your website -> the user submits it -> sending of the notification email about the submission is triggered -> this email goes to the WP Mail SMTP plugin -> WP Mail SMTP plugin routes this email to the mailer -> mailer will send and deliver it further.
When you have trouble getting emails, such an issue could occur if the needed DNS records (SPF, DKIM, DMARC) are not added to your sender domain, or set up incorrectly, and/or your email deliverability score is low because previously you were sending not authenticated emails or you are blacklisted.
You need to make sure that you’ve followed all the steps in our guides on how to set up a mailer.
Also, check your email deliverability score here. And you’ll get a report with issues and ways to improve.
If everything is set up correctly, please, reach out to your chosen mailer support to look deeply into this issue. They’d hopefully be able to help!
Kind regards.
