Newsletter
The first mention gives the date, the item list with quantities and the collection deadline, and opens the volunteer sign-up for the day. The second mention is the collection count against the target and the items still short. The last call is the final count, the volunteer schedule and the packing or serving location.
Social
Save the date is the item list and the deadline, on an image that can be shared outside the church. The reminder post the Friday before is for volunteers: time, location, what to wear. The day-of post is a photograph from the packing line, with the number of families served.
Sunday Announcements
Announce it two Sundays before with the items still short and the volunteer shifts open. The final announcement is the Sunday before the Saturday, which is also the collection deadline: the final count and the schedule for the day.
