Hey @juliankers
Please kindly know, that the WP Mail SMTP plugin is responsible for routing all emails to the mailing service (chosen mailer), and the mailing service is responsible for email delivery. So, the WP Mail SMTP plugin bridges a connection between your WordPress site and your email mailing service (mailer).
When you have trouble getting emails or getting them into the “spam” folder, such an issue could occur if the needed DNS records (SPF, DKIM, DMARC) are not added, 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: https://wpmailsmtp.com/categories/docs/mailers/.
After that, the first step is to send a test email from WP Mail SMTP > Tools to a couple email addresses.
- If they go out fine, it means the WP Mail SMTP plugin is configured properly.
- If you get an on-screen error there is a “See Full Error Log” button if you scroll a bit, click it to see more details about the error.
- If you get a warning, there are links and or instructions on how to fix things in it.
Also, check your email deliverability score here: https://www.mail-tester.com/ (send a test email from WP Mail SMTP > Tools to the email address provided by the tool). And you’ll get a report with issues and ways to improve.
It is important to check your Forms plugin notification settings, ecommerce plugin, newsletter plugin, and any other plugin triggering emails from your site, too. Then test them and see how it goes.
There is also a chance of a conflict with another plugin, here is a guide on how to check for conflicts
If everything is set up correctly, please, reach out to your chosen mailer support about the status of those emails. They’d hopefully be able to help!
I hope this helps!
Please keep me posted
