There are 3 main reasons why you are getting an "Invalid Email" error when signing up:

Your email is disposable or invalid email address.
Your email is from qq.com domain, which is prohibited.
Your email is missing the MX record, which is required for receiving emails.

To verify the validity of your email:

You can check your email with online validators such as this free online tool here.
Use this link to verify that your email has an MX record and isn't disposable: https://api.mailcheck.ai/email/EMAIL_ADDRESS, simply replace the field EMAIL_ADDRESS with your email address.

If the ‘mx’ field is true and ‘disposable’ is false, then the email is valid according to the service.
However, if the service indicates that the 'mx' field is false, it means that your email is missing the MX record. Furthermore, if the ‘disposable’ field is true, it means that your email is disposable.

In case your email is missing the MX record, this online guide can assist you in adding an MX record to your email.
