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!

When scheduling a recurring message via the Send Later pop-up window, you may now indicate that the recurring message should be canceled and deleted from your Drafts folder if you receive a reply to it. This is useful, e.g., if you want to keep periodically reminding someone about something until they reply to indicate that the reminder is no longer needed.
Thanks, as always, to my translation volunteers, for assisting in translating this new feature to many languages!
New feature: Draft messages saved by Send Later are now more reliably marked as “read” so they don’t make your Drafts folder have an unread count unnecessarily.
Send Later now uses separate, unique message IDs for scheduled drafts vs. the messages it actually sends, as well as for different copies of recurring messages. Previously, the message ID which Send Later used when sending a scheduled message was identical to the message ID that was used while the message was being stored in your Drafts folder. Furthermore, Send Later previously used that same message ID for all sent copies of recurring messages. Using the same message ID for drafts and recurring messages was incorrect both because message IDs of different copies of messages are supposed to be unique, and because some mail servers might get confused when a draft and a sent message have the same message ID.
Previously, when a recurring message was sent, Send Later briefly failed to include it in the count of pending messages. Now, Send Later consistently counts recurring messages in the pending message count.
