How to Set Up an Email to Send at a Later Time

Updated February 21, 2017

Most e-mail messages are sent the instant you click the send button--but what if you would like to delay sending your message for a later time or date? Using Microsoft Outlook or Mozilla Thunderbird, you can set up your e-mail messages to send whenever you'd like. This is useful if you have messages that need to arrive on a particular day or time. It only takes a few minutes to arrange your e-mail to send at a specific time and date.

Start Microsoft Outlook and compose an e-mail.

Select "Options" from within the message window.

Check the "Do Not Deliver Before" box. Date and time drop-down menus will appear.

Select a date and time from the drop-down menus.

Click "Close and Send." Your message will be moved to the "Outbox" folder until the send time arrives.

Go to the "Unsigned Byte" website and right-click the link to the "Send Later" Thunderbird extension beneath the "Send Later Extension" heading.

Click "Save Link As..." or "Save Target As...." and save the file to your computer's desktop folder.

Start Thunderbird and click "Tools" from the toolbar, then "Extensions or Tools," then "Add Ons."

Click "Install" and locate the "Send Later" extension file in your desktop folder.

Wait while the extension is installed, then restart Thunderbird when prompted.

Compose the email you want to schedule.

Click "File" and "Send Later."

Select a time and date from the menu or select the "15 Minutes Later," "30 Minutes Later" or "2 Hours Later" option. If you enter your own time, click "Send Later At Specified Time" to confirm.
