What subject line works for Media invoice reminder emails (replied then went silent)?

Name the situation and the business object, not your excitement. Something like "Media note on flights that stall, brand-safety scares," 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 (replied then went silent)?

First reminder 3 days after due date, then 7 days, then a call. 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 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.

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 invoice reminder on LinkedIn instead of email?

Yes if this CTO is actually active there and the thread isn't about payment details. 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.

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.

How Media changes the note

Media buyers are sales leads and operators selling attention in a market that keeps changing the rules. They can smell leftover media-kit language.

Body

Hi [First Name],

This is a reminder, not a scare note. Invoice [number] is still open.

In Media, that usually shows up as flights that stall, brand-safety scares, and follow-up that reads like leftover kit copy. If this needs to be split across two cost centers, I can reissue it.

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

Can you confirm it's in the next payment run?

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