    I’m using WP Mail SMTP, but emails are still not getting delivered to some recipients. The settings seem fine, but I suspect there might be an authentication issue. Can you guide me on how to resolve this?

    Hi @tariqarsenault ,

    Thanks for reaching out. If your emails are only failing for some recipients while your WP Mail SMTP settings look correct, it’s very likely related to email authentication rather than the plugin itself.

    We recommend checking the following:

    • SPF Record – Make sure your domain includes your SMTP provider in a single, valid SPF record.
    • DKIM – Ensure DKIM is properly set up and verified through your email provider.
    • DMARC – Adding a DMARC record can improve trust and prevent delivery issues.
    (In case it helps, here’s a detailed guide on these three.)
    • From Email – This should match your domain (e.g., name@yourdomain.com) and be forced in WP Mail SMTP.

    I hope this helps. Thanks 🙂
