Does Lusha verify its email data?

Lusha provides confidence scores on its contact data but does not perform independent SMTP verification. Community-contributed emails may be outdated or incorrect.

How reliable is Lusha's crowdsourced data?

Quality varies. Some community-contributed emails are current and accurate, while others are months or years old. Verification is the only way to know for certain.

How many Lusha emails are typically invalid?

Community-sourced data tends to have higher invalid rates than direct-lookup tools. Expect 15-25% of Lusha emails to need removal after verification.

Can I verify Lusha contacts from the browser extension?

Yes. Save contacts revealed by the Lusha extension to a list, export that list as CSV, and upload to Truelist for verification before adding them to your sequences.

Lusha is a contact enrichment tool that provides business email addresses and direct phone numbers, primarily sourced through a browser extension and community-contributed data.

Why verify your Lusha email list

Lusha relies heavily on community-contributed data and crowdsourced contact information. While this gives it broad coverage, the accuracy of crowdsourced emails varies significantly. Contributors may share outdated information, and contacts change jobs frequently. Independent verification separates the valid emails from the stale ones.
