Subscribers download the resource but never open it. The useful response is a targeted correction with an observable acceptance check. That keeps the repair tied to the problem instead of turning it into an open-ended redesign.
Find the likely cause
The delivery message hides the promised asset.
Treat this as an explanation to verify against the actual work. Look at the input, the relevant decision, and the final result together. If the evidence does not support this diagnosis, investigate the mismatch before applying a convenient but unrelated fix.
Make the targeted correction
Put a clear download link near the beginning and restate the immediate benefit.
A useful lead magnet helps the same person who could benefit from the paid offer complete a small task.
Check that the repair worked
Test the delivery email and download on a phone.
Repeat the check on the final version that the reader or customer will encounter. An approved draft, a preview, and a published result can differ; the acceptance decision should concern the version people actually use.
Prevent the next related failure
A separate issue to watch for is this: the lead magnet tries to be an entire course. Limit the resource to one task and place optional depth in separate material.
Monitor the useful outcome
Measure resource use and qualified follow-up interest, alongside opt-in volume.
Keep a short record of the original symptom, the evidence behind the diagnosis, and the result of the acceptance check. That record makes the solution reusable when the same condition appears again, without assuming that every superficially similar problem has the same cause.
