Your email list is quietly killing your deliverability.

If you're sending email to a list you haven't cleaned recently, some of your messages are going to spam. Inactive addresses, spam traps, bots, and known complainers drag down your sender reputation with every send.

High bounce rates

Invalid addresses signal to ISPs that you're not maintaining your list. Bounce rates above 2% can trigger throttling or blocks.

Spam complaints from bad addresses

ISPs watch your engagement ratios closely. Inactive and invalid addresses drag down your open rates, and that signals to providers that you're not a sender worth inboxing.

Hidden spam traps and bots

A 0.1% complaint rate is enough to get you blacklisted. Bots inflate your list with fake engagement, masking the real damage happening underneath.

Campaign Refinery goes deeper than basic verification.

Spam Trap Detection

We identify recycled, pristine, and typo-based spam traps that silently destroy your sender score.

Bot and Fake Signup Removal

Detect and remove bot-generated signups that inflate your list with fake engagement.

Seed Account Identification

Find and flag seed accounts that ISPs use to monitor sender behavior.

Complainer Detection

Identify subscribers with a history of marking emails as spam before they damage your reputation.

List cleaning is just the starting line.

Other cleaners verify addresses. Campaign Refinery does that and gives you the platform to keep your list healthy long-term.

Features both Campaign Refinery and other cleaners offer:

• Invalid and disposable email detection
• Spam trap detection
• Native integrations (Mailchimp, ActiveCampaign, Klaviyo, etc.)
• Bot and fake signup detection
• Known complainer detection

Features only Campaign Refinery offers:

• Built into a full deliverability platform
• Engagement-based reputation scoring
• 10,000 contacts cleaned free

Same results, 40-67% less expensive. Campaign Refinery delivers everything above at a fraction of what other cleaners charge. Your first 10,000 contacts are cleaned for free.

What happens when your list is actually clean.

Frequently Asked Questions

Do I have to switch ESPs to use this?

No. Campaign Refinery connects to your existing platform. You keep sending from wherever you send now. We just clean the list underneath.

What does "free" actually mean?

Your first 10,000 contacts are cleaned at no cost, with no credit card required. No trial period, no feature gates. You get the full cleaning engine on those contacts.

How is this different from ZeroBounce or NeverBounce?

Most cleaners verify whether an email address exists. Campaign Refinery goes further by detecting spam traps, bots, seed accounts, and known complainers. It's also built into a full deliverability platform, not just a standalone tool.

How long does cleaning take?

Most lists under 10,000 contacts are cleaned in under 60 seconds. Larger lists take a few minutes depending on size.

Will this affect my current sending?

Not at all. Cleaning happens in the background. Your current campaigns, automations, and sequences keep running without interruption.

What happens after my first 10,000 contacts?

You can continue cleaning additional contacts at Campaign Refinery's standard rates, which are 40-67% lower than most competitors. There's no pressure to upgrade immediately.

Your list is either working for you or against you.

Find out which in 60 seconds. Your first 10,000 contacts are cleaned free, no credit card needed.
