Why this rule existsrationale

A plain http:// link exposes the recipient to interception on exactly the channel carriers are trying to make trustworthy, so it is refused. This is the single highest-consequence cheap defect in the catalog: Twilio's current code for it is NOT eligible for resubmission, so one forgotten "s" can permanently kill a campaign rather than earning a fixable rejection.

How to fix itremediation

Replace every http:// link with its https:// equivalent and confirm the certificate is valid.
