What it does

Verifyre and Campaign Monitor, together.

Reads your lists

Verifyre lists every list in your Campaign Monitor account and streams its contacts page by page, so even a list 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 handled inside Campaign Monitor, after you have reviewed the results.

Setup guide

Set up Campaign Monitor in 4 steps.

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

  1. Create an API key in Campaign Monitor

    In Campaign Monitor go to Account settings, 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 Campaign Monitor and paste the key. Verifyre tests it immediately and shows the account it belongs to. A wrong key says exactly what Campaign Monitor answered.

  3. Verify a list

    Pick a list 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 Campaign Monitor click your profile name (top right), then Account settings, then API keys. Use the account-level key to see every client, or a client's own key (Client settings, then API keys) for just that client.

Write-back

What gets written back to Campaign Monitor.

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.

  • Undeliverable subscribers unsubscribed from the list you verified. Agency keys see every client's lists; a client key sees only that client.

Campaign Monitor FAQ

Campaign Monitor questions

Visit the help centre
Does Verifyre store my Campaign Monitor 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 list. 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.
