Email list hygiene: who on your list is not actually subscribed
The short answer
Good email list hygiene means every contact you mail has current consent. Match each named contact to its latest subscription status across your email platform, ecommerce checkout and store sign-ups, then count contacts with no opt-in, an unsubscribe or a hard bounce. Those records should never reach a campaign or a paid audience.
Why it matters
Mailing people who unsubscribed breaks CAN-SPAM, and mailing people who never opted in raises spam complaints that hurt delivery for the rest of your list. Inflated counts also overstate your reachable audience and skew revenue per email.

What the answer looks like
Illustrative output on sample data
Illustrative example: how Lexi answers this for a pet retailer with 412,000 named contacts across email, point of sale (POS) and loyalty. It reads the latest consent event for each person across every source.
- Subscribed: 268,000
- Unsubscribed: 51,000
- Never opted in: 79,000
- Undeliverable after a hard bounce: 14,000
What the data shows
144,000 named contacts, about 35% of the list, should not receive marketing email.
What it means
Reports that count the full list overstate reach by more than half. Most never-opted-in records come from store checkouts, where consent was not captured.
What to do
Suppress the 144,000 from sends and add a consent prompt at store checkout.

Frequently asked questions
How do I remove unsubscribed contacts from my list for good?
Add unsubscribed contacts to a suppression list and keep them there. Deleting a contact erases the record of the opt-out, so the same address can return through a store sign-up or an import and get mailed again. A suppression list blocks the address in every tool that syncs from it.
Why does my email platform show fewer unsubscribes than my customer records?
Each tool only sees the opt-outs it collected. A customer who unsubscribed in the loyalty app, or asked a store associate to stop emails, may still show as subscribed in the email platform. Bring every consent source into one customer view and apply the most recent event, whichever system recorded it.
How often should I check email list hygiene?
Check suppression sync before every campaign, and run a full status count monthly. A monthly count catches drift from new store sign-ups, imports and integrations that write contacts without a consent flag. Track the share of never-opted-in records over time, since a rising share points to a gap in how consent is captured.
