How many invoice reminders should I send before calling?

Two emails, then a call or a note to the original buyer. Email-only collections stall because AP inboxes are noisy. A short call often reveals a missing PO or a wrong coding string. Name the stall they care about, offer one small next step, and stop before the thread feels like a sequence.

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 Media invoice reminder emails (after a demo)?

Name the situation and the business object, not your excitement. Something like "Invoice [number] is past due ([amount])" 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.

What this CTO actually cares about

A CTO in Media is protecting reliability, security, and engineering time. They look for architecture, failure modes, and whether you'll create toil for their team. Fluff is a ranking signal that you don't know the work. The hook that earns a look is an incident class, a security gap, or a cost line they already hate. The ask should stay at this size: a technical working session or a written teardown, not a 'vision call'. Delete trigger: Calling it 'AI-powered' with no description of the system.

Watch the language. Words that land here include IO, flight, brand safety, CPM, makegood, inventory. Upfronts and flight dates create urgency. Random Tuesdays don't.

Subject

Invoice [number] is past due ([amount])

Body

Hi [First Name],

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

The version of this that matters for sales leads and operators selling attention in a market that keeps changing the rules is rescued two paused IOs by sending a delivery diagnosis instead of another one-pager. Late fees start on [date] per our agreement. I'd rather get it cleared than apply them.

Replay the two moments they leaned in, and the one concern they named.

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

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