A practical example
Example: a gated whitepaper is promoted with utm_campaign=cloud-guide, but the fulfillment email links to a bare PDF URL.
Under the contract, that email must carry the same campaign value so the download session still attributes to the original offer push.
What to evaluate before investing
- Download a test asset and confirm the final file URL or delivery email preserves the required UTM parameters end to end.
- Check whether your gated-host or file server strips query strings on redirect, and whether the vendor supports parameter passthrough.
- Verify the contract document lists every offer link type—promo, redirect, delivery—with required values and an owner for updates.
Limitations and tradeoffs
The contract only governs links you control; third-party marketplaces or partner syndication may rewrite or drop parameters, so treat those channels as separately tracked.
