How do you sell against "people already have a workaround"? (I will not promote)

Talking to potential users who agree the problem is real, but they're already solving it with some manual, unstructured workaround instead of a proper tool. They agree mine is better when I explain it, but conversion is still low. Cold outreach on LinkedIn and email, mostly silence. Is this a messaging problem, a targeting problem, or is beating an existing workaround just a much harder sell than people give it credit for?
