Map your channels.
List where messages go: email, intranet, chat, meetings, newsletters, signage, video and audio. Note who each channel reaches and who it misses.
Give each channel a job.
Use one channel for urgent news, one for reference, one for conversation. Say what goes where, and tell people.
Measure a few things well.
Track reach, completion and a simple understanding check. Add a short question such as: did this help?
Review quarterly and retire what no one uses.
