Same list as six months ago? That's a problem.If your subscriber list looks exactly the same as it did six months ago, you've probably got a problem hiding in it. List cleaning is how you find it, and clear it out, before it drags the rest of your mail down.
⬡ title-card, big "List Cleaning", subtitle fades in: keep · monitor · suppressSo what is it? List cleaning is the process of going through your whole subscriber list and deciding three things for every address. Keep sending to it. Watch it. Or stop sending to it. That's the job.
⬡ checklist, three rows drawn in: Keep · Monitor · SuppressNot just "does it work?"And here's the part people miss. You're not just looking at whether an address technically works. You're weighing engagement history, how the address was collected in the first place, whether the domain is quietly decaying, and whether anything on the list smells like a spam trap. Cleaning uses all of that, not just one signal.
⬡ record-cards, four signal cards light up: engagement · how acquired · domain decay · trap riskWhy bother? Because dead addresses pile up bounces, and addresses that never open teach mailbox providers that people ignore your mail. Send to enough silence and providers start routing you to spam. The cruel part: your best readers, the ones who do open and click, stop seeing you. That's the cost of not cleaning.
⬡ journey-flow, healthy send lands in inbox, then unengaged addresses accumulate and the same send slides toward the spam folderIf that clicked, subscribe. We're working through every list-hygiene question, one plain answer at a time.
⬡ title-card, subscribe promptIn practice it sorts into three buckets. Keep the engaged crew, the folks who open, click, and reply. Monitor the on-the-fence ones, not dead but not warm either, maybe drop them to a lower send frequency or a win-back flow. And suppress the risky ones: hard bounces, likely traps, addresses from lists you can't vouch for.
⬡ split-compare, three lanes: KEEP (steady green line) · MONITOR (flat, watchful) · SUPPRESS (removed from the send)Cleaning ≠ validation.One thing to keep straight. Validation tells you whether an address can technically receive mail. Cleaning tells you whether you should keep sending to it. Related, but different jobs. Validation is one tool cleaning uses, not the whole thing. That's its own video, linked below.
⬡ split-compare, LEFT "Validation: can it receive?" vs RIGHT "Cleaning: should you send?"So a good starting move: run the list through validation to strip the dead addresses, then layer your engagement data on top. The addresses that are technically fine but have been silent for six months? Those are the ones you suppress or move to a win-back flow.
⬡ checklist, ordered: 1 validate out the dead · 2 layer engagement · 3 suppress or win back the silentNext up: how often you should actually run this. And subscribe for the rest of the list-hygiene playbook.
⬡ end-card, Subscribe + Next: "How often should I clean my list?" (005.004.002)What is email list cleaning? It's the process of reviewing your whole subscriber list and deciding, for every address, whether to keep sending, monitor, or suppress. In about three minutes: why cleaning is more than a technical check (it weighs engagement, acquisition source, domain decay, and spam-trap risk), the mechanism by which unengaged addresses push your mail toward spam, the keep/monitor/suppress buckets, and why cleaning is not the same as validation.
