With a seamless ZoomInfo integration, pair your contact data workflows with Allegrow’s high-confidence B2B email verification so you can validate contacts in real time and prevent risky records from ever reaching outbound.
Allegrow’s ZoomInfo integration connects in under 60 seconds via API key, giving your team a single source of truth for verification outcomes so every downstream sync to your CRM or sales engagement platform starts with clean, deliverable emails.

Allegrow brings high-confidence email verification directly into your ZoomInfo workflow, so you can validate contacts before they enter enrichment, routing, or outbound sequences. Instead of exporting lists and hoping they’re clean, you can run real-time validation as part of how your team works — and reduce bounces, spam risk, and “unknown” outcomes on hard-to-verify B2B infrastructure and catch-all domains.
What you unlock with ZoomInfo + Allegrow
To connect ZoomInfo with Allegrow, you’ll need an active Allegrow subscription and your Allegrow API key. ZoomInfo will use this key to authenticate requests to Allegrow’s Validate Email (Synchronous) endpoint, which returns a verification result immediately.
Note: this endpoint has a 30-second timeout. If a validation takes longer, retry after waiting the suggested time returned in the response.
Connect in a few steps
Allegrow provides a dedicated Customer Success Manager (CSM) as your primary point of contact for anything related to the ZoomInfo integration — setup guidance, best practices, and scaling your workflow safely.

Your Customer Success Manager proactively reaches out to schedule meetings with you and other relevant stakeholders during your Allegrow subscription to help you utilise the functionality Allegrow contains. You may also have the facility to access your customer success manager's calendar and schedule a meeting at a time that is convenient for you and your team. In addition to this, Allegrow will send automated reputation reports and alerts during your subscription.
