Hubspot CRM Integration

Log in to your No2Bounce account. In the left sidebar, click Email Validations, then select the CRM Integrations tab at the top of the page.

You will see three integration options: Salesforce, Hubspot, and HubSpot. Click the Connect button on the Hubspot card to begin the authorization flow.

You will be redirected to Hubspot's secure authentication page. Enter your Hubspot email address or mobile number and click Next to proceed with your password.

Alternatively, use one of the social sign-in options: Google, Apple, Yahoo, Facebook, LinkedIn, X (Twitter), or Microsoft. If you don't have a Hubspot account, click Sign up now to create one for free.

After signing in, Hubspot will display a permissions consent screen showing what No2Bounce is requesting access to. The permissions include:

• Group scope toperform CRUD operationson CRM metadata
• READaccess to fetch data using CRM Object Query Language
• PerformCRUD operationson CRM modules (Contacts, Leads, Accounts)
• Group scope toupdate records in bulk

Check the "I allow No2Bounce to access the above data from my Hubspot account" checkbox, then click Accept. You will be automatically redirected back to No2Bounce.

No2Bounce only accesses your CRM data to read contacts and write validation results back. Your data is never shared with third parties.

Once authorization is complete, you are redirected back to No2Bounce's CRM Integrations page. The Hubspot card now shows a green CONNECTED badge in the top-right corner, and two new action buttons appear:

• Import List— opens the Hubspot Integration contact management view
• Disconnect— safely unlinks your Hubspot account at any timE

Click Import List to proceed to the next step.

‍

The Hubspot Integration page opens with module tabs at the top: Home, Leads, Contacts, and Accounts. Select the module containing the records you want to verify.

Under Choose Columns, click the dropdown to select which fields to import — at minimum, select the Email column. You may also add Last Name, Full Name, First Name, or any other relevant fields for context. Then click Load Data to preview your records.

Select your columns (including Email) and click Load Data to preview CRM records.

Your contacts load in a table showing all selected columns. Use the checkboxes to select individual records, or click the top checkbox to select all at once. You can also use the search/filter bar to narrow down specific contacts before selecting.

Once your selection is ready, click the Validate Now button in the upper-right corner to begin the email verification process.

‍

After clicking Validate Now, you are redirected to the Validation Progress page. A circular progress indicator shows real-time completion percentage. Once complete (100%), results are displayed and automatically written back to your Hubspot CRM records.

The results summary breaks emails into three categories:
_Deliverable

●Valid, safe to send

_Risky

●Catch-all or uncertain

_{UnDeliverable}

●Invalid do not send Download

_Report

Available for 7 days

The Validation History table below logs every past run, showing date, source, number of records, deliverable/risky/undeliverable counts, status, and a download link.

‍

After validation completes, the following fields are written back to your Hubspot CRM contact records automatically:

N2B_Status— Deliverable, Risky, or UnDeliverable

N2B_Score— Numeric email quality score (0–100)

N2B_SubStatus— Detailed sub-classification (e.g. catch_all, invalid_domain)

N2B_Validation_Timestamp— Date and time the email was last verified

When the Catch-All option is enabled during validation, No2Bounce performs a deeper check on domains that accept all incoming mail — helping you identify higher-risk addresses that a standard check may mark as valid.

• Catch-all verification consumes1 additional credit per email
• Results are tagged in theN2B_SubStatusfield ascatch_all
• You can choose to enable or disable catch-all per validation run
