Read Receipts / Tracking Notification Every time email is opened
I like how the 'Read Receipt' works, however, I do not like how it only shows a receipt the first time the recipients opens the email. Rather, I believe that the user should receive a notification every time the user opens the email. As an everyday user or even a sales professional, it would showcase that the email is being read, but no response has been given. It might spark to send a quick follow up sparking a response.
