Thanks for all of the input!
I DO tend to stick to ONE email per week UNLESS there is a last-minute change need people to know about. My weekly email is set up kind of like a weekly agenda with important things (e.g. things that have deadlines or are just really important) in bold or red.
Example:
Tuesday 6/9
- Practice: NOON- 2 in West Gym (blue tank/gold shorts/white bow)
- Tumbling at Westside: 6-7:30 (OPTIONAL DAY)
- DUE: YOUTH CLINIC GROUP LEADER APPLICATIONS (5:00 PM)
I think this format works well just because no one has time to read full sentences. Based on that, you really have no reason to text and ask "What do we wear Monday?" Isn't that clear enough?
In terms of emails I send when there are CHANGES, the subject will read (example) TIME CHANGE - FITTINGS (yes, all caps) and will just say "Fittings will now take place in the
East Gym at 9 AM." Change is in bold. Simple enough, right?
I generally don't request a response, but I think that is something I will start based on your suggestions. Thanks!
