Keap Email Verification Integration

Clean your Keap contacts with Mailthentic to cut bounces and protect sender reputation. A native Keap connector is available on request, and you can verify your list today.

Native connectors are built on request for customers on a paid plan.

Why verify your Keap lists

Keap campaigns trigger on contact actions, so an invalid address enters a sequence and bounces immediately, with no human in the loop to catch it. Keap is strict about deliverability and a rising bounce rate can put your sending privileges at risk, not just your inbox placement. Verifying contacts before they hit a campaign keeps your automations and your account healthy.

Keap, formerly Infusionsoft, is a CRM and marketing automation platform for small businesses, combining contact management, campaign builders, pipelines and payments in one system.

How Keap verification works

Verify your Keap list today in three steps.

1

Export your Keap contacts as a CSV

From the Contacts area, filter the group or tag you want to clean and export it to CSV. Any file with an email column works.

2

Upload the CSV to Mailthentic's bulk verifier

We verify every address: syntax, domain and MX, disposable, catch-all, role based and risky patterns, with a clear verdict per record.

3

Download the clean list and import it back into Keap

Re-import the deliverable contacts and tag or opt out the invalid ones. Paid customers can request a native Keap integration and our team will build it, removing the CSV step.

Benefits for Keap users

Fewer bounces from campaign sequences

Keap campaigns fire automatically. Verifying first stops sequences from sending to addresses that never existed.

Protect your sending privileges

Marketing automation platforms monitor bounce rates closely. A verified contact base keeps you well inside acceptable thresholds.

Stop paying for contacts you cannot reach

Keap plans scale with contact count. Removing unreachable records means your spend follows your real audience.

Cleaner pipeline and lead data

Sales pipelines built on contacts that cannot receive email waste rep time. Verified data means every lead in the pipeline is contactable.

Reliable automation triggers

Goals and decision branches driven by opens and clicks only behave correctly when the underlying addresses are deliverable.

GDPR aligned processing

Verification runs on our infrastructure with a DPA available, so EU contact data can be cleaned without weakening your compliance posture.

What Mailthentic checks

Every Keap contact runs through the full verification stack.

Syntax validation

Every Keap contact is checked against RFC rules, catching malformed addresses that arrive from web forms, imports and manual entry.

Domain and MX record checks

We confirm the domain exists and publishes mail exchange records, so contacts at closed companies and misspelled providers are flagged before a campaign runs.

Disposable email detection

Throwaway addresses used to claim a lead magnet are identified, so they never enter a Keap campaign or count against your plan.

Catch-all domain detection

Domains that accept every address at the server are flagged, so you know which Keap contacts carry residual bounce risk before you automate against them.

Role based address flagging

Shared mailboxes such as info@, admin@ and support@ are marked. They engage poorly with automated sequences and raise complaint risk.

Risky and invalid address detection

Mailbox level checks separate confirmed invalid addresses from risky ones, so you can opt the dead ones out and send carefully to the rest.

Keap use cases

Cleaning before a campaign build

Verify the contact group before you point a new Keap campaign at it, so the sequence starts on data you can trust.

Scrubbing imported lead lists

Event, webinar and partner lists carry the most bad addresses. Verify them before they enter Keap and trigger automations.

Restoring a rising bounce rate

If bounces have climbed, verify the contact base, opt out the invalid records and rebuild volume on a clean list.

Annual contact hygiene

People change jobs and companies close. A regular verification sweep keeps your Keap database contactable.

Frequently asked questions

Is there a native Keap integration?
Not yet. A native Keap integration is available on request: paying customers can request it and our team builds and enables it for their account. Until then you can verify your Keap contacts today by exporting a CSV, running it through our bulk verifier and re-importing the clean file.
How do I verify my Keap list today?
Export your contacts from Keap as a CSV, upload the file to Mailthentic's bulk verifier, then download the clean results and import the deliverable contacts back into Keap.
Will verifying reduce my Keap bounce rate?
Yes. Confirmed invalid addresses cause hard bounces, and hard bounces are what put marketing automation accounts under review. Removing them before campaigns run is the most effective fix.
What about catch-all domains?
Catch-all servers accept mail for any address, so no verifier can prove a specific mailbox exists. We flag them clearly rather than guessing, and you decide whether to send, pace or hold those contacts.
Is my Keap contact data secure?
Uploads are processed for verification only. We never sell, rent or reuse your data, processing is GDPR aligned and a DPA is available on request.
How are credits charged for a Keap export?
One credit per email address in the file. You can trial the workflow on the free tier before buying a credit pack or taking a subscription.
