A bloated list costs you money and tanks your deliverability. This prompt identifies every subscriber who has gone quiet, tells you what they're costing you, and gives you a clear plan for what to do next.
Every email platform charges you based on your subscriber count. That means every cold subscriber who never opens your emails is costing you real money every month while actively hurting your deliverability scores.
Most founders know they should clean their list but never do because the process feels complicated. You have to figure out who is inactive, decide what to do with them, and then actually move them somewhere before you delete anyone.
This prompt runs the whole audit for you. Claude pulls your cold subscribers, calculates the cost, and gives you a tiered plan: who to re-engage, who to move to a cold segment, and who to remove entirely.
Before running the audit, decide what inactive means for your list. If you email weekly, 90 days without an open is a clear signal. If you email monthly, you might extend that to 120 or 180 days. Pick one number and commit to it before you start.
Paste the prompt below into Claude with your Kit connector active.
Look at my Kit subscriber list and identify everyone who has not opened any of my emails in the last 90 days. How many subscribers is that? What percentage of my total list are they? Estimate what they're costing me per month based on my current plan pricing. Then give me a three-tier plan: who to try to re-engage, who to move to a cold segment, and who to remove.
Claude will return a segmentation plan. The re-engagement tier typically includes subscribers who were active within the last year but dropped off recently. The cold tier includes subscribers who have never opened more than one or two emails. The removal tier is anyone who has never opened a single email since subscribing.
Before removing the re-engagement tier, send a simple three-email sequence: one subject line that acknowledges the silence, one that delivers value, and one that asks directly whether they want to stay on the list. Anyone who opens stays. Anyone who does not gets moved to the removal group.
Once your re-engagement window closes, remove the non-responders from your active list. Archive their data before you delete in case you need to reference it later. Your deliverability and billing both improve immediately.
A clean list is a healthy list. Run this audit every 90 days and your deliverability stays strong, your bills stay lower, and the people receiving your emails are actually the ones who want to be there.
