How many times should I follow up with a CTO (long time no contact)?

First reminder 3 days after due date, then 7 days, then a call. Send when you have a real trigger: news, a useful artifact, a role change, a season. 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.

Is it weird to email someone after six months of silence?

Not if you have a new reason and you don't pretend the old thread is still warm. Lead with the trigger, remind them who you are in one line, and make the ask optional. Nostalgia without news is just another cold email with extra steps.

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 should I never say in a Non-Profit invoice reminder?

Don't imply their mission is inefficient. Help them tell it better. Calling it 'AI-powered' with no description of the system. Don't open with 'it's been a while' and then paste the old pitch. Those three mistakes show up constantly in Non-Profit inboxes and they all read as "this was templated."

What this CTO actually cares about

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

How Non-Profit changes the note

Non-Profit buyers are ED teams, development leads, and program directors stretching every dollar. Don't pitch like a VC. Mission language has to be specific to their programs, not a generic 'doing good.' A credible proof point in this vertical sounds like: improved second-gift conversion 17% with thank-you notes that named the program, not the CRM. Watch the language. Words that land here include restricted funds, board, grant cycle, stewardship, program officer. If you cannot name a gala, a grant deadline, or a board meeting with a gap in the packet, wait until you can.

Subject

Can we clear invoice [number] this week?

Body

Hi [First Name],

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

In Non-Profit, that usually shows up as donor follow-up that feels automated and grant calendars that punish delay. If this needs to be split across two cost centers, I can reissue it.

Given this is long time no contact, ask if the old problem still exists, or if you should leave it archived.

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

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

Questions people ask before they hit send

Name the situation and the business object, not your excitement. Something like "Can we clear invoice [number] this week?" 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.
