Email Validation for HubSpot CRM

Why Validate Emails for HubSpot?

HubSpot's CRM quality depends on clean contact data. Invalid emails clog your pipeline, skew analytics, and waste sales team time on unreachable leads. Validation ensures your CRM data stays accurate and your automation workflows trigger correctly.

Benefits

• ✓ Keep your CRM data clean for accurate sales forecasting
• ✓ Reduce wasted sales outreach to invalid email addresses
• ✓ Improve marketing automation trigger accuracy
• ✓ Maintain HubSpot score integrity with verified contacts

How to Validate HubSpot Emails

1. Step 1: Export contacts from HubSpot CRM as a CSV via the Contacts dashboard
2. Step 2: Run the list through email validation to identify invalid addresses
3. Step 3: Use the HubSpot API to update contact properties with validation results
4. Step 4: Set up a workflow to automatically flag or block new invalid signups

API Integration

Integrate email validation directly into your HubSpot workflow:

// HubSpot API - Update contacts after validation
const hubspot = require("@hubspot/api-client");

const client = new hubspot.Client({
  accessToken: process.env.HUBSPOT_API_KEY,
});

// Batch update contacts with validation status
const batchInputPublicAssociationBatchInput = {
  inputs: invalidEmails.map((email) => ({
    id: contactIdMap[email],
    properties: {
      email_validation_status: "invalid",
     Lifecycle_Stage: "other",
    },
  })),
};

await client.crm.contacts.batchApi.update(batchInputPublicAssociationInput);
