What subject line works for Insurance cold email emails (after an invoice)?

Name the situation and the business object, not your excitement. Something like "Idea for [Company Name]'s [pain]" outperforms "Just checking in" because a CTO 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 CTO (after an invoice)?

Don't follow a cold email the next morning. Give it 4 business days. A polite reminder a few days after due, then a firmer operational note. After that, send a breakup note and archive it. A CTO 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. Name the stall they care about, offer one small next step, and stop before the thread feels like a sequence.

How do I follow up on an unpaid invoice without damaging the relationship?

Assume a process issue first. Put the facts up top, offer to fix coding or PO problems, and keep the tone operational. Escalate to the original buyer only after AP has had a fair chance. Rage emails get paid last.

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

Yes if this CTO 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.
