Why this rule existsrationale

This five-word set is honoured at handset and carrier level regardless of what you configure, so a consumer using any of them has effectively opted out whether your platform noticed or not. Declaring them aligns your suppression list with what has already happened.

How to fix itremediation

Declare at least the universal five, and preferably the full seven-word FCC per-se set including REVOKE and OPTOUT.

STOP, QUIT, END, REVOKE, OPTOUT, CANCEL, UNSUBSCRIBE

Notesnotes

Discharges catalog CMP-184 ("optoutKeywords is populated and retains STOP") together with OPS-027, which owns the empty-list case. The split is deliberate: this rule returns UNCLEAR rather than FAIL on an empty list so that a campaign with no keywords yet is reported once, by OPS-027, instead of twice.

Rules you will hit next

5 other rules read campaign.optout_keywords. Fixing one field to satisfy a single rule is how a resubmission trades one rejection for another, so read these before you change anything.

Reading the rules is the easy part.

Ekas runs every rule that gates approval, 823 of these 915, against your registration before it reaches the carrier. It reads your site, your policy pages and your opt-in the way a reviewer would, and hands you the fix, not just the verdict.
