GoHighLevel Email Verification

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

GoHighLevel is an all-in-one CRM and marketing platform popular with agencies and their clients. Mailthentic integrates directly with GoHighLevel to help you verify and clean your contact database without CSV exports or manual work.

How It Works

Four steps to a clean GoHighLevel database.

1

Connect GoHighLevel

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

2

Import contacts

Pull contacts or lists from GoHighLevel. 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 GoHighLevel. Invalid contacts are tagged so you can exclude them from campaigns.

Why Verify Your GoHighLevel Contacts

Protect every sub-account

Agencies run many client sub-accounts; one dirty list can hurt deliverability for all.

Reduce campaign bounces

Verify contacts before email and SMS campaigns so bounces do not pile up.

Cleaner automations

Verified contacts keep your workflows and pipelines accurate.

Verify at capture

Use the API to verify form and funnel signups before they enter GoHighLevel.

Frequently asked questions

How does Mailthentic connect to GoHighLevel?
Mailthentic connects to GoHighLevel securely, imports your contacts, verifies every address with the 9-point engine, and writes clean results back. You never share your GoHighLevel 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.
