From the team behind SpamKill (opens in a new tab) — spotting spam since 2018 · {{TBD:contacts-analyzed}} contacts analyzed · Works with your platform:

  • Mailchimp
  • HubSpot
  • ActiveCampaign
  • Brevo
  • Constant Contact

The warning email isn't the problem. Your list is.

Dead & fake addresses

Lists decay roughly 25% a year. Every dead address is a bounce waiting to happen.

Bots using real people's emails

Bots fill your forms with other people's real addresses. They pass verification — then the real owner hits "report spam."

You pay for it twice

Bad contacts drag your sender reputation down and inflate your ESP bill every single month.

List rot happens to every list. Let's fix it — calmly.

A warning from your email platform is scary; email is your revenue channel. The good news: this is fixable, usually before your next send.

Since 2018, we've blocked bad signups at the door with SpamKill. Spam Clean is the other half of the job — removing the bad contacts already inside your list. Same team, shared detection methods.

"We got a bounce warning the week before our biggest send of the year. The free analysis showed us exactly which contacts to pull — we cleaned the list and shipped the campaign on schedule. No panic, no guesswork."

Diagnosis before surgery.

    A guaranteed minimum count of bad contacts, plus a sample you can verify yourself.

  3. Clean by color

    Act in minutes — no deliverability degree required.

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

Nothing is ever deleted without your approval. Uncertain contacts are flagged for review — never auto-removed.

Why "verified" lists still get spam complaints.

Name John Smith
Email sarah.jones@gmail.com
Deliverable address. Real person. Never signed up.

Standard verifiers pass this contact because the address works. But Sarah never signed up — and when your email lands, she hits "report spam." Spam Clean catches these with name-to-email matching.

Common questions

No. Nothing is deleted without your approval, and anything uncertain is flagged amber or yellow for review — never auto-removed.

Encrypted in transit and at rest, never shared, never emailed, and purged after {{TBD:retention-days}} days. Full details on our Security page.

Free analysis in {{TBD:turnaround-hours}} for most lists. Cleaning starts right after, so you can fix things before your next send.

The analysis is always free. Cleaning is priced by list size — see Pricing.
