Emacs Gnus delay (schedule) email sending

I always forget how to schedule my emails and it’s a pain to look up because Gnus uses the word “delay” instead of “schedule”, so here it is. Note that for gnus message scheduling (delaying) to work, you will need a line like this in your init file:

(gnus-delay-initialize)

In a message buffer with Gnus you can execute C-c C-j (gnus-delay-article) to schedule an item for a later sending. After that I see it scheduled in my nndraft:delayed folder with a “date” line describing the time at which it will be sent. Note that if I wasn’t initiating this message with C-x m (compose-mail), such as when it was just an src message block in an org-file, the delay won’t work and the message won’t be saved to any folder.

Delete it from the gnus folder to cancel the sending.
