I definitely understand. This is actually a pretty common occurrence as well. WordPress uses a specific mailer right out of the box that normally gets flagged in your email inbox. So try checking your Spam folder for the email, you’ll likely see it there.
If you don’t see the email you may want to reach out to your web hosting provider and work with them to access your website at the server level where you can also change your primary WordPress email. Your web host should be have knowledge on how to perform this task.
Thanks Alex-Ann, I hope you find this information useful.
