Email Validation for HubSpot CRM

Connect CampaignKit to HubSpot CRM to verify contact email addresses automatically. Avoid manual data import/exports by using our built-in HubSpot integration:

• Bulk validate all your contact's email addresses without import/export
• Automatically validate new and updated contacts
• Works with multiple HubSpot accounts

CampaignKit uses the HubSpot API and WebHooks to communicate with your HubSpot account. It's possible to connect multiple HubSpot accounts.

When connecting CampaignKit with HubSpot CRM, CampaignKit creates two additional contact attributes. Those attributes are used to store CampaignKit's validation results:

• CampaignKit Email Class: Valid, Invalid or Risky
• CampaignKit Email Score: 0 - 10

CampaignKit never removes or modifies data in your HubSpot account. Validation results are stored in the attributes, which can be used to filter your contacts.

Simple Setup Process

It takes a few simple steps to get started. In CampaignKit, navigate to New Integration and select HubSpot.

CampaignKit starts the authorization flow. You'll be redirected to HubSpot's consent screen, where you approve and gant access to your account.

Your accounts are now connected. New and updated contacts will be validated automatically from now on. To bulk validate your existing contacts use the CampaignKit App to start the bulk validation process.

How the HubSpot API integration keeps contacts current

CampaignKit subscribes to HubSpot's contact webhooks. Whenever a contact's email address is set or changed in HubSpot, HubSpot notifies CampaignKit, which validates the new address and writes the result to the CampaignKit Email Class and Email Score properties. Each automatic validation of an address that passes the syntax check uses one credit.

Contacts that were already in HubSpot before you connected are covered by a one-time bulk validation from the CampaignKit App. Read the full HubSpot setup guide for screenshots of every step.
