check email exist or not wordpress

To check if an email exists in WordPress, you can follow these steps:

1. Log in to your WordPress admin dashboard.
2. Navigate to the "Users" section.
3. Click on "Add New" to add a new user.
4. Enter the email address you want to check in the "Email" field.
5. If the email already exists, you will see a notification indicating that the email is already registered. If the email does not exist, you will be able to proceed with creating a new user account with that email.

I hope this helps!
