Step 1

Upload securely

Connect Mailchimp, HubSpot, ActiveCampaign, Brevo, or Constant Contact directly. Your file is encrypted in transit and at rest, and deleted after {{TBD:retention-days}} days.

  • Mailchimp
  • HubSpot
  • ActiveCampaign
  • Brevo
  • Constant Contact

Step 2

The analysis: what we check

  • Deliverability

    Does the address actually exist and accept mail?

  • Disposable addresses

    Ten-minute throwaway inboxes that will never convert.

  • Spam traps

    Addresses that exist only to catch careless senders — the reputation killers.

  • Catch-all domains

    Domains that accept everything; deliverability unknown, flagged for review.

  • Role accounts

    info@, sales@ — inboxes, not people.

  • Name-to-email mismatch

    Unique

    Bot signups using real people's valid addresses — the ones standard verifiers pass.

Step 3

The report

You get a guaranteed minimum count of bad contacts and a verifiable sample from your own list — every address sorted into a colour-coded verdict tier.

  • Red — remove with confidence
  • Amber — review first
  • Yellow — review first
  • Green — keep

Nothing is auto-deleted. You approve every removal.

Step 4

Clean & export

Remove the red tier in one click, work through the review queue at your pace, and export the clean list straight back to your platform.

{{TBD:turnaround-hours}} for most lists, {{TBD:turnaround-large}} for very large ones.

Never. Verification happens without sending anything to your list.
