Frequently Asked Questions

Can I use both services simultaneously during migration?

Yes, absolutely. Many customers run both services in parallel for a testing period to compare results before fully switching to BillionVerify. This helps ensure a smooth transition and validates the accuracy improvements.

How does BillionVerify achieve higher accuracy than DeBounce?

BillionVerify uses advanced AI algorithms combined with real-time SMTP verification and a proprietary spam trap database. Our multi-layer verification process includes machine learning pattern recognition that adapts to new email patterns faster than traditional database-driven methods. We process millions of verifications daily, continuously improving our detection models.

Will my existing DeBounce integrations work with BillionVerify?

Most platforms that integrate with DeBounce also support BillionVerify. We offer native integrations with 25+ platforms including Mailchimp, HubSpot, SendGrid, and more. Our support team can help with any custom integrations. The API migration is straightforward and typically takes less than 30 minutes.

What happens to my DeBounce credits when I switch?

DeBounce credits remain in your DeBounce account and expire after 12 months. We recommend using them up before fully migrating. BillionVerify offers competitive pricing that will save you 40-50% on future purchases, and our credits never expire.
