Keap Email Verification

Verify Keap contacts before your next campaign. Connect your Keap account, verify every email address, and push clean results back, all automatically.

Keap (formerly Infusionsoft) is a CRM and marketing automation platform for small businesses. Mailthentic integrates directly with Keap to help you verify and clean your contact database without CSV exports or manual work.

How It Works

Four steps to a clean Keap database.

1

Connect Keap

Paste your API key once to connect. No password sharing.

2

Import contacts

Pull contacts or lists from Keap. Duplicates are removed automatically.

3

Verify every email

Each address runs through the 9-point engine including SMTP mailbox confirmation, catch-all and disposable detection.

4

Push results back

Clean results sync back to Keap. Invalid contacts are tagged so you can exclude them from campaigns.

Why Verify Your Keap Contacts

Clean contact data

Verify emails before campaigns and automations so bounces do not pile up.

Protect deliverability

Fewer bounces from Keap sends means better inbox placement.

Focus on reachable contacts

Flag invalid addresses so your follow-ups reach real people.

Ongoing hygiene

Run recurring verification as new contacts enter Keap.

Frequently asked questions

How does Mailthentic connect to Keap?
Mailthentic connects to Keap securely, imports your contacts, verifies every address with the 9-point engine, and writes clean results back. You never share your Keap password.
Does verification send emails to my contacts?
No. Verification uses DNS lookups and SMTP handshakes to confirm a mailbox exists without delivering any message, so your contacts are never emailed.
How much does it cost?
The integration is free. You pay only for verification credits used, one credit per unique address. Every new account starts with 100 free credits, no credit card required.
