Mailchimp counts unsubscribed contacts toward your plan until you archive them. Listgevity marks every address Inbox, Caution or Remove so you know what to archive.
Mailchimp counts unsubscribed contacts toward your plan size until you archive them. So a contact who left two years ago can still be costing you every month. On top of that sit the addresses that never unsubscribed but went dead: abandoned inboxes, closed jobs, typos from the signup form. By our own estimate, 12 to 20% of a list goes stale every year.
You do not have to switch tools to use us. Run your list through whatever checker you use today, then send us only the addresses it marked risky or unknown. Those are the hard calls, and they are where a plain decision saves you the most. You pay for a small file, not the whole list.
Export your audience from Mailchimp and send us the file. A person on our side checks every address and sends it back within about a day, each one marked:
| Verdict | What it means | What you do |
|---|---|---|
| Inbox | Safe to mail | Keep them in every flow |
| Caution | Risky, mail with care | Segment them, do not blast |
| Remove | Dead weight | Suppress or delete them |
Archive the Remove ones in Mailchimp so they stop counting toward your plan, and hold the Caution ones out of your next big send.
Will this lower my Mailchimp bill? It can. Archived contacts stop counting toward your plan size. Note your contact count before and after so you see the difference in your own numbers.
Do you need my Mailchimp login? No. You export the audience yourself and email it to us. We never touch your account.
Does this guarantee the inbox? No, and be careful with anyone who says they can. We take the dead weight off your list. The inbox you earn with good sending from there.
What does it cost? The first 50 addresses are free. After that, we quote a price for your list before we run anything. See pricing.
Run your list through Listgevity and get Inbox, Caution or Remove on every address, with the reason.
