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 allows you to verify the performance improvements.
How does BillionVerify achieve 40x faster real-time API responses than Bouncer?
BillionVerify uses optimized multi-threaded SMTP verification with intelligent caching and global CDN distribution. While Bouncer's real-time API can take up to 30 seconds, BillionVerify maintains sub-300ms average response times through advanced infrastructure and algorithm optimization.
Will my existing Bouncer integrations work with BillionVerify?
Most platforms that integrate with Bouncer also support BillionVerify. We offer native integrations with 25+ platforms including Mailchimp, HubSpot, SendGrid, and more. Our API structure is similar, making migration straightforward. Our support team can help with any custom integrations.
What happens to my Bouncer credits when I switch?
Bouncer credits remain in your Bouncer account and never expire. We recommend using them up before fully migrating. BillionVerify's pricing will save you 80-92% on future purchases, making the switch financially beneficial.
How long does API migration typically take?
Most customers complete API migration in under 30 minutes. The API structure is similar to Bouncer's, requiring mainly endpoint URL changes and header adjustments. We provide detailed migration guides and code examples. Our support team is available 24/7 to assist.
Do you offer bulk migration discounts?
Yes! Contact our sales team for special migration offers. We often provide bonus credits or discounted rates for customers switching from competitors. High-volume users can receive custom enterprise pricing with additional savings.
Is there a minimum commitment or contract?
No, BillionVerify offers pay-as-you-go pricing with no long-term contracts. Credits never expire, giving you complete flexibility. Unlike monthly subscriptions, you only pay for what you actually use.
Can I export my verified lists from Bouncer and import them to BillionVerify?
Yes, you can export your verified lists from Bouncer and upload them to BillionVerify for re-verification or storage. We support all major file formats (CSV, Excel, TXT, JSON), making the transition seamless.
Why is BillionVerify's batch processing slower but more affordable?
BillionVerify optimizes for a balance of speed, accuracy, and cost. While our batch processing is 50K/hour versus Bouncer's 200K/hour, we achieve higher accuracy (99.9% vs 97% audited) at 80-92% lower cost. For most businesses, completing 100K emails in 2 hours versus 30 minutes isn't significant when savings are substantial.
Does BillionVerify charge for "unknown" results like Bouncer doesn't?
BillionVerify follows standard industry practices for charging verified emails. However, our superior accuracy (99.9% vs 97% audited) means you get fewer "unknown" results overall, and our 80-92% lower pricing more than compensates for any difference in unknown result handling.
