The email platform
built for inbox placement.
Stop losing 20-30% of email revenue to the spam folder.
Every day you send to a dirty list, you're making your deliverability worse.
Spam Traps Are Lurking
Even clean, well-maintained lists pick up spam traps over time. Hit just one and your sender reputation takes a serious hit across your entire domain.
Dead Weight Drags You Down
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.
Complainers & Bots Poison Everything
A 0.1% complaint rate is enough to get you blacklisted. Bots inflate your list with fake engagement, masking the real damage happening underneath.
A complete deliverability platform. Use as much or as little as you need.
A complete deliverability platform. Use as much or as little as you need.
Deep Cleaning
Goes way beyond basic validation. We detect seed accounts, bot signups, and sophisticated spam traps that slip right past services like ZeroBounce and NeverBounce.
Real-Time Protection
New subscribers get verified the moment they enter your list. Bad addresses never make it in, so your list stays clean from day one.
Automatic Re-Cleaning Every 90 Days
Lists decay. Addresses go stale, people change jobs, domains expire. We re-scan your entire list automatically so you never have to think about it.
Deliverability Health Score
Get a letter grade from A to F with a full breakdown of what's in your list and what's hurting you. Plus a branded report you can keep and share with your team.
List cleaning is just the starting line.
Verification gets you started. Campaign Refinery keeps you there.
Same results, 40-67% less expensive.
Campaign Refinery delivers everything above at a fraction of what other cleaners charge. Connect your ESP and your first cleaning is free, up to 10,000 contacts.

Ongage charges $1,499/mo for their premium tier and caps you at 7M sends/month. Campaign Refinery gives you more with no send caps, no contact limits, and no platform fee.
You choose when to use it.
Start by cleaning your list and keep sending from your current ESP. That works perfectly on its own. When you're ready to take full control, connect your own Mailgun, SendGrid, or Amazon SES relay and send through Campaign Refinery. No pressure, no timeline. The platform is there when you want it.
What's the cost of NOT cleaning your list?
If even 5% of your list is toxic and you have 50,000 contacts, that's 2,500 addresses actively damaging your sender score every single send.
Each email you send to a spam trap makes the next campaign harder to inbox. Each bounce chips away at your domain reputation. And the damage compounds daily.

Questions worth answering.
Will this affect my current ESP setup?
For BYO, we connect and clean your list while you keep sending from your current ESP. Managed and Done For You customers move to Campaign Refinery infrastructure as part of onboarding.
What does the free cleaning include?
We clean every contact currently in your ESP account at the time of onboarding, up to 10,000. If you have 500 contacts, we clean 500. If you have 15,000, we clean the first 10,000. After that, additional cleaning uses our credit-based pricing. No subscription required. BYO credits never expire.
How is this different from ZeroBounce or NeverBounce?
Most cleaners verify addresses and detect spam traps, bots, and complainers. Campaign Refinery does all of that too, but it's also built into a full deliverability platform with engagement-based reputation scoring. It's not just a cleaning tool. It's the system that keeps your list healthy long-term, at 40-67% lower cost.
Is my list data safe?
Yes. Your data is never sold, shared, or used for any purpose other than cleaning. Period.
What ESPs do you support?
For list cleaning, we currently support Kit (ConvertKit) and Klaviyo. If you also use Campaign Refinery to send email, we support Mailgun, Amazon SES, and SendGrid as sending relays.
What if I have more than 10,000 contacts?
We'll clean up to 10,000 for free. Any contacts beyond that can be cleaned at our credit-based pricing, which is 40-67% lower than competitors. BYO credits never expire.
Are there any requirements to qualify?
Yes. You need an active ESP account with sending history. We reserve the right to decline accounts that don't meet our activity guidelines in order to prevent abuse.
Your list is either working for you or against you.
