 * in the additional headers area – we have the following
 * Bcc: [email@domain.com](https://wordpress.org/support/topic/syntax-error-149/email@domain.com?output_format=md)
   
   Reply-To: [email]
 * however when we save it – it shows “This field has syntax errors.”
 * any ideas as to why?

 * Make sure that the email mail-tag in the FORM is required(*). e.g.
 *     ```
       [email* email]
       ```

 * is that just a suggestion?
    or do you believe that will make the syntax error
   go away?

 * I think it will resolve your issue. At present the user can leave the email field
   empty in the FORM , as it is not a required field, but then your syntax in MAIL
   states that the reply-to address is the email address in the [email] mail-tag.
   Hence the validation error. Try it for yourself. Nothing will break 🙂
