Five B2B enrichment engines unified inside HubSpot

Combine telecom, messaging, identity, mailbox, and domain reputation signals before assigning leads to sales reps.

Caller ID (CNAM) vs Contact Name match

Caller ID intelligence

Retrieves telecom-registered Caller Name and compares it against the HubSpot contact name so SDRs spot fake form entries immediately.

Caller ID API

Phone Carrier & VoIP screening

Global E.164 normalization

Identifies Mobile, Landline, and disposable VoIP numbers while writing normalized E.164 numbers and carrier metadata back to CRM properties.

Phone Number Validator

Silent WhatsApp & Business detection

Zero messages or OTPs sent

Checks whether a prospect’s phone number is active on WhatsApp or WhatsApp Business so reps prioritize the highest-reply outreach channel.

WhatsApp Number Checker

Email deliverability & 50+ DNSBL checks

Mailbox + domain reputation

Blocks burner temp-mail signups and screens company domains or form submission IPs across 50+ real-time DNS blocklists.

IP & Domain Blacklist Checker

HubSpot Workflow branching recipes

Use output tokens from the ProWebLook custom workflow actions to automate SDR routing and list hygiene.

Fast-track high-trust WhatsApp leads to SDRs

Assign leads immediately when both email and WhatsApp are verified on a real mobile line.

Trigger: Contact submits Demo Request Form
Action 1: ProWebLook - Enrich Contact Lead
Branch: High-Intent Mobile Lead
  trust_score >= 75
  AND phone_line_type == "Mobile"
  AND whatsapp_registered == true
Then: Rotate record to Sales Owner + Create high-priority task

Quarantine disposable emails & VoIP burner signups

Prevent marketing email bounces and fake trial abuse automatically.

Branch: High Fraud / Bounce Risk
  is_disposable == true
  OR email_deliverable == false
  OR phone_line_type == "VoIP"
Then: Set Marketing Contact status to Non-Marketing + Add to Suppression List

Screen target account domains before outbound

Check company domain reputation before enrolling prospects into sequences.

Trigger: Company enters Outbound Prospecting stage
Action: ProWebLook - Check Domain & IP Blacklist (target = Company domain)
Branch: Clean Domain (listed == false)
Then: Enroll associated contacts in outbound sequence

Frequently asked questions

Which HubSpot objects support the ProWebLook UI Extension card?

The React UI Extension card works on Contacts, Companies, and Deals in both the middle record tab (crm.record.tab) and the right sidebar (crm.record.sidebar).

Does re-opening a Contact record in HubSpot consume credits every time?

No. Lookups are cached for 12 hours using SHA-256 keys in Cloudflare KV, and synced results are stored directly in custom HubSpot contact properties until you explicitly click re-verify.

How are HubSpot OAuth tokens and webhook requests secured?

Every incoming HubSpot request is verified with HMAC-SHA256 X-HubSpot-Signature-v3 and timestamp replay checks, OAuth tokens are encrypted at rest with AES-256-GCM, and GDPR privacyDeletion webhooks purge portal records automatically.

Can Breeze AI agents inside HubSpot invoke ProWebLook actions?

Yes. The custom workflow actions expose structured typed inputs and output tokens compatible with both HubSpot Workflows and Breeze AI automation.

Can I try the HubSpot card before buying a credit plan?

Yes. Every new ProWebLook account includes 50 free one-time credits each across email, phone, WhatsApp, caller ID, and blacklist checks, plus a built-in starter sandbox.
