Describe the bug

When users try to subscribe by entering their email, there is no validation or improper validation of the email format. As a result, users are able to enter incorrect or improperly formatted email addresses, causing issues with subscription or registration.

Expected behavior

When users enter their email in the subscription form:

The email should follow the standard format, i.e., username@domain.com. If the email format is incorrect, an error message should appear, prompting the user to enter a valid email. The form should not be submitted until a properly formatted email is entered
