TOO MANY EMAILS AND MEETINGS

TOO MANY EMAILS AND MEETINGS
I am wondering if any of you feel like your company has a good email/meeting structure defined? I am attempting to streamline these for our company to help reduce unnecessary emails and set expectations for meetings and other communication. From Executives, VP's, Regional Managers, site-level staff.
Anything you can share is greatly appreciated.
 

Isn't it CRAZY? We've asked our teams not to reply all (unless it's truly a reply all issue), not to send thank you emails acknowledging an email, and if they are sending an email to a large group put all the email addresses in bcc rather than in the top line so people can't reply all to the whole group. 
On meetings, we are wrestling with all our newer client wanting a weekly call that typically lasts an hour, after we've already sent them a weekly report that tells them everything that we review in the call. The interesting thing is that property performance seems to be better for our long term clients that don't require a weekly call. In other words, we have more time to do "all the things" rather than talk about them. When meeting with potential clients we discuss frequency of calls, asking that they not be weekly, except the first month or so. 
As for team meetings, we zoom each other weekly for Manager calls, monthly for Maintenance team members, and monthly for Leasing team members.  We also have a very brief weekly Town Hall, all employees, for celebrations, anniversaries, company updates. We think it's a unifying call, and in the last survey 88% of team members still wanted it. So we continue!
