Hi, I heard of this Gmail-competitor MUA recently. https://superhuman.com/ Reading through its list of features, it seems quite easy to think of scripting some of them, e.g. delayed sending by refiling into a to-send folder that's posted in the background, or appending a future reminder to a per-day file to be inc'd.
For the avoidance of doubt, this isn't suggesting we ship features like this, just a reaffirmation that being able to script mail-processing programs that work well together, and with the rest of Unix, is powerful. -- Cheers, Ralph. -- nmh-workers https://lists.nongnu.org/mailman/listinfo/nmh-workers
