Subject: Closing your file, {{first_name}}?
Hi {{first_name}},
I've reached out a handful of times about {{your_product}} and {{specific_problem}} at {{company}}, and I'm not getting a read on whether this is a now-thing or a not-now thing.
Rather than keep adding to your inbox, I'll close the file at my end. If anything changes — new initiative, budget shifts, the {{relevant_trigger}} actually happens — you know where to find me.
No reply needed. Wishing you well either way.
