From 4Team Corporation:
SendLater is a free e-mail scheduler allowing you to handle your e-mail correspondence in a timely manner even if you are away from your computer. Prepare all your e-mail notifications and reminders, greetings in advance and schedule their delivery. As long as your computer is online, your e-mail will be sent automatically even Outlook is not running (supporting Exchange accounts as well). Each time you reply or create a new delayed e-mail message, you will be able to choose a particular time and recurrence for your PC to send your message. Just click the 'Send Later' icon on the toolbar and select the sending time using time-and-date/recurrence selector. Click 'Send later' and your message will be scheduled for that time/recurrence and saved in the 'Send Later' folder. Automatically resend the email in case no answer was received in given time using the new "Re-send" button. Specify a number of times the email has to be re-sent. You can also resend already sent items. Stop the recurrent sending if a response is received from the recipient. Now with the latest Windows 10 and Outlook 2016 support.
What's new in this version:
- This update includes improvement of the "Use email or Exchange server directly" option so it would work with Exchange accounts available via Exchange Web Services, as well as several other bug fixes.
