How soon should I send a thank-you after a meeting?

Same day, ideally within a few hours. Waiting until the next morning is fine if the meeting ran late. Waiting until Friday for a Monday meeting makes it look like a chore. Name the stall they care about, offer one small next step, and stop before the thread feels like a sequence.

Why do prospects reply once and then disappear?

Often they needed to check with someone, a fire started, or your last ask was bigger than they meant to take on. A good follow-up shrinks the next step and references what they already said so they don't have to reload context.

Is it okay to send this thank you on LinkedIn instead of email?

Yes if this department head is actually active there and the thread isn't about long attachments. Keep the LinkedIn version even shorter. Don't paste the full email. One context line and one question is plenty. Name the stall they care about, offer one small next step, and stop before the thread feels like a sequence.

Subject

Thanks for the straight talk on [topic]

Body

Hi [First Name],

Thanks for [specific action]. It actually unblocked [outcome].

In SaaS, that usually shows up as time-to-value that slips past the first 14 days and quietly becomes churn. No need to reply. I just wanted this on the record.

Given this is replied then went silent, ask if the blocker is timing, people, or the work itself.

If I can return the favor, say the word.

Best,
[Your Name]
[Your Title]
[Your Company]
