I am looking for recommendations on how to communicate accomplishments and address other typical O3 topics with my High I manager who regularly cancels the scheduled O3s and who is a listener rather than a reader.

When the O3 is cancelled I send an email summary of what I would have covered divided into sections: 1) Critical Info for my supervisor; 2) Review of past 30 day accomplishments; 3) Update on COTs

Is there a better way to structure the email or organize the information?
