What subject line works for Manufacturing cold email emails (replied then went silent)?

Name the situation and the business object, not your excitement. Something like "Department Head question on replied then silent" outperforms "Just checking in" because a department head can decide from the preview text whether it's worth opening. Keep it under 50 characters when you can.

How many times should I follow up with a Department Head (replied then went silent)?

Don't follow a cold email the next morning. Give it 4 business days. Give it a week unless they named a date. Then write on that date, not the day after you got impatient. After that, send a breakup note and archive it. A department head who wants it will answer a clean close more often than a fifth bump.

Should I mention a mutual connection in a cold email?

Only if the connection would be comfortable with it. Name-dropping someone who barely knows you can backfire. If you do mention them, say exactly how you know them in one clause and move on. Tie the note to one metric or stall they already own, and keep the ask answerable in a single sentence.

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 cold email 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. Tie the note to one metric or stall they already own, and keep the ask answerable in a single sentence.
