One of the best email validator available in market

We use ZeroBounce to validate email IDs of our target prospects. The business problem the product addresses is weeding out bad contacts/bad emails from our outreach emails which improves deliverability, reduces bounce rate. Additionally we then check for new companies for those prospects and update email IDs accordingly. Scope of use case is limited to marketing and sales emails.

ZeroBounce has been fairly accurate in filtering out unwanted email addresses. But sometimes there is a time lag - Once a prospect leaves the company, they keep the domain active - so in such case ZeroBounce will say this is a valid email ID - fair point but they should add an indicator like prospect moved out of the company.

Yes, ZeroBounce has continuously protected our data securely. They are ISO certified and ensure the PII are not exposed. They have the security measures in place and our GRC team also did some due dligence on the platform to ensure they are compliant. The data encryption and decryption happens very securely.
