What it does

Verifyre and Mailchimp, together.

Reads your audiences

Verifyre lists every audience in your Mailchimp account and streams its contacts page by page, so even a audience of hundreds of thousands never has to be exported.

Verifies with a real handshake

Each address goes through syntax, DNS, disposable and role checks and an SMTP conversation with its own mail server, with per-domain politeness so no provider is hammered.

Writes the verdict back

Undeliverable contacts are tagged, unsubscribed or suppressed, your choice, inside Mailchimp, after you have reviewed the results.

Setup guide

Set up Mailchimp in 4 steps.

You will need: a Verifyre account (free) and your Mailchimp api key.

  1. Create an API key in Mailchimp

    In Mailchimp go to Account & billing, then Extras, then API keys and create a key named Verifyre. Copy it; you will paste it once and never see it again on our side (it is encrypted with AES-256-GCM at rest).

  2. Connect it in Verifyre

    Sign in, open Integrations, choose Mailchimp and paste the key. Verifyre tests it immediately and shows the account it belongs to. A wrong key says exactly what Mailchimp answered.

  3. Verify a audience

    Pick a audience from the list, confirm the credit estimate (one credit per unique address, duplicates are free) and start. Watch the counts fill in live; you get an email when the job is done.

  4. Push results back

    From the finished list, choose the write-back action. Verifyre applies it only to undeliverable contacts by default; risky contacts (catch-all domains, role accounts) are left for you to decide on with the exported CSV.

Where exactly the api key lives

In Mailchimp click your profile picture, then Account & billing, then Extras, then API keys. Click Create A Key, give it a name and copy the key (it ends in -usN).

Write-back

What gets written back to Mailchimp.

Verification only reads. Writing results back is a separate step you trigger after reviewing the counts, and nothing is ever deleted without your say-so.

  • A member tag "Verifyre: undeliverable" on every address that cannot receive mail, so you can build a segment and archive or exclude them in one go.
  • Or the member status set to Unsubscribed, which keeps your audience count (and your Mailchimp bill) honest.

Mailchimp FAQ

Mailchimp questions

Visit the help centre
Does Verifyre store my Mailchimp contacts?
Contacts are held only for the duration of the job and the result rows you can download; the credentials are encrypted and can be disconnected at any time, which deletes them.
How many credits does a sync use?
One credit per unique, well-formed address in the audience. Duplicates, syntax failures and addresses verified in the last 24 hours are free.
Will it unsubscribe contacts without asking?
No. Verification only reads. Writing back is a separate step you trigger from the finished list, and you choose which action to apply.
Does this count against Mailchimp's contact limit?
Tagging does not change your contact count. Unsubscribing keeps the contact but Mailchimp does not bill for unsubscribed contacts, so cleaning usually lowers your plan tier.
