Delayed Send for Auto Email for Activities/Events
I like to hold off on sending emails until the 1-2 days before and the registration has been closed. These emails include things like my personal number, weather conditions, and overall serve as a reminder. Most people find accessing an email from a phone easier than accessing it from the website (and I don't want to include my phone number on postings).
Sometimes the ideal time to send an email conflicts with other activities (ie I might be leading a conditioning hike or doing a race the night before a morning run). To get around this, I will sometimes send an email 2-3 days before, but then new people join and I don't get a chance to email them before the event.
It would be great if I could input the email into the activity somewhere, schedule a time to send, it would auto-send on that specific date/time, then get send to any additional registrants who sign up after the originally scheduled time.
