What does the email and phone validation feature do?

This feature verifies the accuracy and validity of emails and phone numbers, ensuring your contact data is correct, up-to-date, and ready for outreach.

How does it work?

Our system cross-checks emails and phone numbers against multiple validation providers, detecting invalid, outdated, or risky contacts to reduce bounce rates and improve deliverability.

What happens if an email or phone number is invalid?

If a contact is flagged as invalid or risky, you can remove or update the record before sending outreach campaigns, ensuring your messages reach the right people.

“With an end-to-end platform that allowed reps to supplement their contacts with verified data and engage best-fit prospects all in one place, we increased sales qualified leads by an extraordinary 70%.”
