The Monitor Reply feature helps you to keep on top of your email communications by advising you when someone hasn't replied to your emails.
To use Monitor Reply:
1) Send an email with Mailtrack.
2) Click on the monitor reply option in the pop-up that appears in the bottom left-hand side of the screen.
And that's it!
If you don't receive a reply to the email after 24 hours you will receive an email notification advising you that you've not received a response yet.
