Why this rule existsrationale

The published bound is 40 to 4096 characters, and anything near the floor cannot contain the audience, content and opt-in source a reviewer needs. Enforcing the real bound rather than a guessed heuristic also prevents the opposite failure, where a long, thorough description is silently truncated on submission.

How to fix itremediation

Expand the description to explain who receives the messages, what they contain, and how recipients opted in. Aim well above the 40-character floor.

A compliant exampleexample

Acme Coffee sends weekly promotional offers, new product announcements, and loyalty rewards updates to customers who opted in via the checkout consent checkbox at acmecoffee.com.

Notesnotes

The current contentFlags scanner uses a 40/100 heuristic with no upper bound — this replaces the guess with the published bound.
