Hello penelope323,
Thank you for your reply.
It seems like the server might not be sending emails correctly.
To simplify things, I recommend keeping WP Mail SMTP active for testing purposes.
You don’t need to activate any services like Brevo—just enable the plugin and use the “Test Email” feature to check if emails are being sent.
Additionally, it would be a good idea to contact your hosting provider and ask if your server is configured to send emails. Some hosts require a third-party SMTP service, while others do not. Confirming this with your host will give us more clarity.
As for DKIM, it’s an alphanumeric key added to your DNS as a security measure. It helps verify that an email was genuinely sent from your domain and not someone pretending to be you.
Let me know what your host says, and i’ll be happy to assist further.
Best regards.
