Hello,
Thanks for reaching us here!
Please check your email for the spam messages, sometimes it will forward the messages to the spam section of your email address. If you do not find them there, so the most common reason for emails going missing is that your WordPress hosting server is not properly configured to use the PHP mail() function. Emails sent by WordPress websites often fail this test. This means that when an email is sent out from your WordPress site, it may not even make it into the recipient’s spam folder let alone inbox. So, we recommend everyone to use SMTP for sending emails in WordPress. Because, unlike the PHP mail() function, SMTP uses proper authentication which leads to high email deliverability.
WordPress has a WP Mail SMTP plugin that configures your WordPress site to send emails using SMTP instead of the PHP mail() function. Please try this way to send testy emails.
Best Regards
