❌ Waiting too long to send the notice
Why it matters: A last-minute rescheduling letter — sent the day before or the morning of the meeting — wastes the recipient's preparation time and signals poor planning on your part.
Fix: Send the letter as soon as you know the original date is unworkable, even if your preferred alternative slots are not yet confirmed — a preliminary heads-up followed by a full proposal is better than a single late notice.
