About this Add-on
You can specify a specific time and date, or click "15 mins later", "30 mins later" or "2 hours later", or click "Put in Outbox" to get the built-in Thunderbird "Send Later" functionality (i.e., copy to Outbox).
For additional information, see the user guide.

Send Later uses SugarJS by Andrew Plummer. Thanks Andrew!
Please email me bug reports, suggestions, etc.
Unfortunately, limitations in the Thunderbird add-on framework make it somewhere between difficult and impossible to make scheduled messages with Send Later work safely and properly when the Enigmail add-on is installed and enabled.
However, Send Mail can successfully deliver previously scheduled messages even when Enigmail is active.
Therefore, Send Later now displays an alert pop-up and disables the scheduling of messages when Enigmail is enabled. If/when Enigmail is disabled or uninstalled and Thunderbird is restarted, Send Later automatically re-enables itself.
The Development Channel lets you test an experimental new version of this add-on before it's released to the general public. Once you install the development version, you will continue to get updates from this channel. To stop receiving development updates, reinstall the default version from the link above.
Caution: Development versions of this add-on have not been reviewed by Mozilla.
