Do you know when to send a group email over an IM group message?

Large distribution group emails (e.g NorthwindAll@, SSWAll@) should be used for critical information or emails that require feedback from users. For general information or random posts, reduce email noise by using an IM group (e.g. Microsoft Teams).

Group emails serve an important purpose in providing information to the entire organization in a way that is less likely to get lost than an Instant Message. It also provides a good method of allowing for a good cross section of staff responses. IM messages are better suited to general comments/information or random posts.
