How to archive inactive Mailchimp contacts to lower your bill

Run the free audit — browser-only, nothing uploaded

Subscribed contacts who never open still count toward your Mailchimp contact limit. Mailchimp's own advice for avoiding extra charges is to segment contacts who aren't interacting with emails (or buying) and archive them (About Additional Charges). Their dedicated walkthrough is Archive Inactive Contacts.

What to expect on the bill

Archived contacts don't count toward your current contact total and can be unarchived later (source).
Billing uses the peak contact total in each period, so archiving won't cut a peak already recorded this cycle — it helps later periods (source; peak billing explained).
Mailchimp suggests trying a re-engagement campaign before you archive, in case some inactive contacts are still worth winning back (source).

Method 1: segment by email interaction (non-openers)

Click Audience, then Segments. Pick the audience if you have more than one.
Click Create segment.
First condition: Campaign interaction → has not opened, then choose from Aggregated Emails.
Click Add filter (keep And). Second condition: Campaign interaction → was sent, same Aggregated Emails list — so you only target people who were sent those emails and didn't open.
Optional: add Email Date Added → is before → [date] so brand-new subscribers who haven't received mail yet aren't archived (Mailchimp tip).
Click Review Segment, select the contacts, click Archive, type ARCHIVE, confirm.

Source steps: Archive Inactive Contacts — Segment and archive by email interaction.

Method 2: segment by contact rating

Audience → Segments → Create segment.
Condition: Contact Rating → is less than → 2 stars (one-star / negative rating). Mailchimp recalculates ratings when you send (source).
Review, select, Archive, type ARCHIVE.

Also archive the easy billable statuses

Inactive subscribed contacts are only one slice. Unsubscribed and (often) non-subscribed contacts still count toward the limit until archived (About Mailchimp Pricing Plans):

Archive unsubscribed contacts in bulk
Non-subscribed contacts and your bill
Duplicates across audiences (same email billed once per audience)

Measure before you archive

Export each audience, then run AudienceTrim's free audit in your browser. It counts unsubscribed, non-subscribed and cross-audience duplicates (nothing is uploaded). Use Mailchimp segments above for inactive subscribed openers — those engagement fields aren't in the static export ZIP the same way.

FAQ

Will archiving inactive contacts lower my Mailchimp bill this month? Not if you already hit a higher peak this billing period. Mailchimp bills on peak contact total; archiving helps future periods.

Should I re-engage before archiving inactive subscribers? Mailchimp recommends trying a re-engagement campaign first, because some inactive contacts can still generate revenue.

How do I avoid archiving brand-new Mailchimp subscribers? Add a segment condition Email Date Added is before a date prior to your recent sends, so new contacts who haven't received email yet stay subscribed.

Do archived inactive contacts keep their data? Yes. Archiving removes them from the marketing audience without losing data, and you can unarchive later.
