What makes a CTO reply to outreach?

Evidence you understand their stack constraints and won't waste engineering time. Mention a real integration, a failure mode, or a security question you already answered. Demo theater is how you get routed to /dev/null. Name the stall they care about, offer one small next step, and stop before the thread feels like a sequence.

What subject line works for Marketing invoice reminder emails (after a demo)?

Name the situation and the business object, not your excitement. Something like "Marketing note on attribution arguments, creative fatigue," 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 a demo)?

First reminder 3 days after due date, then 7 days, then a call. Same day with the recap. A value bump 3 days later if they went quiet. 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 apologize for sending an invoice reminder?

No. You can be polite without acting like asking to be paid is a favor. State the facts, offer help if something is blocked, and keep the next step obvious. Name the stall they care about, offer one small next step, and stop before the thread feels like a sequence.

Should I include a recording in the demo follow-up?

If you recorded it and they agreed, yes, plus timestamps for the two parts they cared about. A raw 40-minute link with no map is homework. Add the three bullets they'd need to brief a colleague. Name the stall they care about, offer one small next step, and stop before the thread feels like a sequence.

What this CTO actually cares about

A CTO in Marketing is protecting reliability, security, and engineering time. They look for architecture, failure modes, and whether you'll create toil for their team.

Body

Hi [First Name],

Flagging invoice [number] for [amount], due [date].

I'm writing because a budget cut, a rebrand, or a channel that stopped converting. Pay here: [link]. Invoice PDF is attached / linked. If the PO, coding, or approver is the blocker, tell me and I'll fix our side today.

Answer the real objection and make internal forwarding easy.

Who on your side should I talk to if this isn't your queue?

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

Questions people ask before they hit send
