Mailchimp · list hygiene & tier savings

Your Mailchimp list is full of people who stopped listening. Listfit finds them.

Mailchimp charges by contact count. Every inactive subscriber on your list is money you pay for zero engagement. Listfit scores every contact — keep, borderline, or prune — shows you exactly how many to archive to drop a billing tier, and does it in one recoverable click.

How it works

Four steps from messy list to clean tier.

Connect once. Listfit scores your list, shows you exactly who to archive, and handles the removal — safely and reversibly.

/01

Connect your Mailchimp account

Paste your Mailchimp API key. Listfit reads your list engagement data for scoring. Your key is never stored in plaintext. Setup takes under 60 seconds — no developer required.

/02

Listfit scores every contact

A scan runs across your audience. Each contact is scored on engagement signals — open rate, click rate, recency — and assigned to a band: Keep, Borderline, or Prune.

/03

Review the scorecard and savings

See your band breakdown and exactly how many contacts to archive to drop your Mailchimp billing tier. Listfit shows the monthly savings before you touch anything.

/04

Archive in one click — recoverable

Listfit archives the prune-band contacts in Mailchimp. It is a soft archive — Mailchimp keeps them for restoration. Never a hard delete. You keep every record, every time.

What you get

Four things Listfit does so your bill doesn't grow on autopilot.

Scoring

Per-contact engagement scoring

Every contact gets a score based on open rate, click rate, and recency. Scores map to three bands — Keep, Borderline, Prune — so you know exactly which contacts are earning their seat on your list and which are deadweight.

Tier savings

Tier-boundary savings estimate

Listfit shows you exactly how many contacts to archive to cross your next Mailchimp pricing boundary — and the exact dollar amount you save per month. No guessing, no spreadsheet math.

Archive queue

One-click archive queue

Review your prune candidates before committing. Optionally include borderline contacts. When you are ready, confirm the archive in one click. Listfit batches the removal and polls until it is done.

Safety

Recoverable — never a hard delete

Listfit archives contacts in Mailchimp — it is a soft archive, not a hard delete. Mailchimp retains archived contacts for restoration. Your data is always recoverable. We never permanently remove a contact on your behalf.

Entitlement

Free scorecard. Paid archive.

Scoring and the savings estimate are free — always. You see exactly what Listfit found before paying anything. The one-click archive queue requires the Standard plan at $29/mo flat. No contact-count pricing; no surprises.

Data

API key only. Tenant-isolated.

Listfit connects via your Mailchimp API key — read-only for scoring, targeted archive writes only. Your key is never stored in plaintext. Tenant-isolated storage means your list data is never mixed with another customer's account.

Security & safety

Your list data. Your archive. Your call.

Archive is always reversible

Every archive action is a soft delete in Mailchimp — contacts are archived, never hard-deleted. Mailchimp retains them for restoration. Listfit never permanently removes a contact on your behalf, ever.

API key, never stored in plaintext

Your Mailchimp API key is used to read engagement data and perform targeted archives. It is never stored in plaintext and never shared. Tenant isolation ensures your list data is never mixed with another customer's account.

Data residency & tenant isolation

Your scan data stays in the region you choose at signup: EU-Central or US-East. Row-level security and composite key constraints ensure your data is isolated at the database level — not just the application layer.

No. Listfit archives contacts in Mailchimp — it is a soft archive, not a hard delete. Mailchimp retains archived contacts and you can restore them at any time from your Mailchimp account. Listfit never permanently removes a contact on your behalf.
You paste your Mailchimp API key into Listfit. The key is used to read your list engagement data for scoring, and to perform targeted archive operations when you confirm them. Your key is never stored in plaintext. You can disconnect at any time from your Listfit account settings.
The free plan runs a full scan, scores every contact, and shows you the Keep / Borderline / Prune breakdown plus the exact tier-boundary savings estimate — how many contacts to archive and how much you save per month. You see the full picture before paying. The archive action itself requires the Standard plan at $29/mo flat.
Each contact is scored on engagement signals from your Mailchimp data: open rate, click rate, and recency of last engagement. Contacts with consistently low or zero engagement across all signals land in the Prune band. Contacts with some engagement land in Borderline. Active contacts land in Keep.
Yes. In the archive queue, you can toggle the option to include borderline contacts alongside prune-band contacts. When you do, Listfit re-previews the full candidate set. The decision is yours — borderline contacts have some recent engagement, so archive them with caution.
Cancel any time. No cancellation fees. Your Mailchimp connection is removed, your scan data is deleted within 30 days, and you remain on the free plan indefinitely with read-only scorecard access. Anything already archived in Mailchimp stays in its archived state — Listfit's cancellation does not restore or re-add contacts.
No. Standard is a flat $29/month regardless of how many contacts you have or how many you archive. Mailchimp charges you by contact count — Listfit charges you a flat fee to help lower that count. There are no per-contact or usage-based charges on the Listfit side.
You choose your region at account creation: EU-Central (Frankfurt) or US-East (Virginia). Scan data stays in that region and does not replicate across regions. Tenant isolation ensures your data is never mixed with another customer's. Full detail is in the Privacy Policy.
