E-mail Follow-Up is a Microsoft® Outlook® add-in that allows (and reminds you!) to send follow-up e-mail messages if a reply has not been received within a specified time-frame. E-mail Follow-Up will watch for messages and show an alert when a reply has not been sent. This Outlook add-in also allows you to send a follow up message using a predefined template to remind the recipient that the reply hasn’t been sent.
