Email Schedule Send Thunderbird

Sending Email at a Scheduled Date / Time in the Future Using Mozilla Thunderbird: Install the "Send Later 3" (Thunderbird 3.1+) extension. It extends the Send Later functionality by bringing up a scheduler for the time when the “Send Later” option is chosen (Ctrl+Shift+Enter is the shortcut). The extension saves the message to draft and monitors the messages in the draft folder, when the chosen time arrives it moves the message to unsent and sends unsent messages. Now you can send email in the future!

Download Thunderbird 3.1+ version of the extension using below link. You will need to save it your hard disk and then install it from Thunderbird Extension Manager.

Restart Thunderbird.

Sit back, relax and have a cuppa.

How to Usage:

If you want to control how often the add-on checks for messages to be delivered, edit its preferences from Tools > Add-ons. The default is 60 seconds. The background polling status is shown the status bar as “SL8TR [IDLE 00]”, if there are messages in the draft folder waiting to be sent later the message reads, e.g., “SL8TR [PEND 3]” (it says "SENDLATER3" instead of "SL8TR" for the newer version of the add-on).

If you want to schedule a message to send later, just choose “File->Send Later” (or CTRL+SHIFT+ENTER) after composing an email.

This will prompt you with the time and date in a "pop-up" window, select the time and date and Click on “Send at specified time”.

If you want to use the default Thunderbird Send Later functionality you can choose “Pass through to Send Later”.
