Post-Launch UTM Link Drift Monitor

Launch-day validation only proves links worked at go-live. This workflow keeps watching: on a recurring schedule it re-tests every published campaign link for HTTP health, unexpected redirects, and UTM parameters that got stripped by a CMS change or a shortened-link expiry. It compares each result to the last known-good baseline and alerts only when a healthy link degrades, so the channel stays quiet until something actually breaks.

Use it during the live window of any campaign with meaningful spend, where a silently broken link means wasted budget and lost attribution. It is especially valuable for long-running evergreen campaigns and links that pass through redirectors or third-party CMSes you don't fully control.

1. 1A schedule trigger runs the check at your chosen interval during the campaign window.
2. 2The workflow reads the live link registry from Coda, including each link's last-good baseline.
3. 3It re-validates every URL for 200 status, final redirect target, and intact UTM params.
4. 4A logic step diffs current results against the baseline to detect new degradations only.
5. 5For any newly broken or drifted link, it posts a targeted alert to Slack with the before/after.
6. 6It updates the baseline in Coda so resolved issues won't re-alert.
