Today's Email: How to clean your list without killing your reach

Your list needs regular cleaning. But most people either clean too aggressively and lose good subscribers, or they don't clean at all and let their deliverability slowly decay.

Why cleaning matters in the first place

Every time you send to someone who never opens, never clicks, and never buys, you're telling Gmail and Yahoo one thing: people don't want your emails.

Do that enough times and your emails start landing in spam for everyone. Including the people who actually want to hear from you.

Cleaning isn't about shrinking your list. It's about protecting the subscribers who care.

Step 1: Define "inactive" before you remove anyone

This is where most people mess up. They pick an arbitrary window like "hasn't opened in 90 days" and mass-delete.

That's too aggressive for most businesses.

Instead, think about your sending frequency:

• If you email daily or multiple times a week: 90 days of no engagement is meaningful.

• If you email weekly: 120-150 days is more realistic.

• If you email twice a month or less: go out to 180 days before calling someone inactive.

The window should match your cadence. Someone who gets two emails a month has had maybe 12 chances to engage in 180 days. That's very different from someone who got 180 emails in the same period.

Step 2: Don't delete. Suppress first.

Removing someone from your list is permanent. Suppressing is reversible.

Move inactive subscribers into a suppressed segment. Stop sending them your regular campaigns. But keep them on the list.

This does two things:

• Your engagement rates improve immediately because you're no longer diluting them with inactive contacts.

• You still have those subscribers available for re-engagement later.

Deletion should be the last step, not the first.

Step 3: Run a re-engagement sequence before suppressing

Give inactive subscribers one last shot before you move them.

A simple two or three email sequence works:

Email 1: Acknowledge the silence. "We noticed you haven't opened in a while. Here's what you've been missing." Include your best recent content or offer.

Email 2 (3-5 days later): Ask directly. "Still want to hear from us? Click here to stay on the list." One clear button. No pressure.

Email 3 (if needed, 5-7 days later): Let them know this is the last email they'll get unless they re-engage. Be straightforward, not dramatic.

Anyone who opens or clicks during this sequence moves back to your active list. Everyone else gets suppressed.

Step 4: Check for false positives

Before you suppress, look at your inactive segment more carefully.

• Are any of them recent purchasers? Someone who bought last month but didn't open your last three emails is not inactive. They're a customer.

• Are any of them Apple Mail users? Apple's Mail Privacy Protection auto-loads tracking pixels, so some "openers" aren't really opening. But the reverse is also true. Some people reading your emails aren't registering as opens.

• Are there subscribers who click but don't "open"? This happens more than you'd think. Check click data separately from open data.

These false positives are real subscribers you'd lose if you only looked at open rates.

Step 5: Make cleaning a recurring process

List cleaning isn't a one-time project. Set a schedule.

Quarterly works for most businesses. Monthly if you send at high volume. Twice a year if your cadence is light.

Every cycle: identify inactive subscribers, run re-engagement, suppress those who don't respond, delete only the ones who've been suppressed through multiple cycles with zero engagement.

The goal isn't a small list. It's a healthy one.

A well-maintained list of 8,000 engaged subscribers will outperform a neglected list of 25,000 every single time. Better open rates. Better click rates. Better inbox placement. Better revenue per send.

Clean regularly. Suppress before you delete. Re-engage before you suppress. And always check for false positives.

That's the whole process.

Best,
Alec
