Feingeist Software GmbH announces MailButler, the Apple Mail assistant, recently added a new productivity-boosting feature on its list. It's called Follow-Up, and it allows users to schedule a follow-up reminder that will notify them when there is no response to a particular email. Once the email is written, the user can just tell MailButler when he wants to be reminded, and the notification will appear on his preferred date & time. MailButler simplifies, optimizes and streamlines working with emails. MailButler is Free and can be downloaded from their website.
