It’s possible that the email address that you changed in WordPress is not the same email address that is associated with your user account or the email address that is used for email notifications.
To verify the email address associated with your WordPress user account, log in to your WordPress site and go to the Users section in the admin panel. Click on your user account to edit it and check the email address listed there. If it’s not the email address you want to use, update it to your current email address.
If the email address listed in your user account is correct, you may need to check the settings for email notifications in your WordPress site. Go to Settings > General in the admin panel and check the email address listed in the “Email Address” field. This is the email address that WordPress uses for sending email notifications, such as new user registrations, password resets, and comment notifications.
If the email address listed in the “Email Address” field is not the one you want to use, update it to your current email address.
If you’ve checked both your user account and the email settings and the correct email address is listed in both places, then it’s possible that there’s an issue with your email provider or email client that’s preventing you from receiving the confirmation email. You could try contacting your email provider’s support team for further assistance with this issue.
Finally, if you’re still not receiving the confirmation email, you could try using a different email address or email provider to see if that resolves the issue.
