What subject line works for Non-Profit invoice reminder emails (replied then went silent)?

Name the situation and the business object, not your excitement. Something like "Invoice [number] is past due ([amount])" outperforms "Just checking in" because a founder 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 Founder (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 founder 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 founder 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.
