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 EmailVerify. This helps ensure a smooth transition and validates the accuracy improvements.
How does EmailVerify achieve higher accuracy than Kickbox?
EmailVerify uses advanced AI algorithms combined with real-time SMTP verification and a proprietary spam trap database with 1M+ identified traps. Our multi-layer verification process includes machine learning pattern recognition that adapts to new email patterns faster than traditional methods, catching 40% more disposable emails and risky addresses.
Will my existing Kickbox integrations work with EmailVerify?
Most platforms that integrate with Kickbox also support EmailVerify. We offer native integrations with 25+ platforms including Mailchimp, HubSpot, SendGrid, and more. Our support team can help with any custom integrations, and our API structure is straightforward for developers.
What happens to my Kickbox credits when I switch?
Kickbox credits remain in your Kickbox account but expire after 6 months. We recommend using them up before fully migrating. EmailVerify's non-expiring credits mean you'll never lose unused verification capacity, and our competitive pricing will save you money on future purchases.
How long does API migration typically take?
Most developers complete API migration in under 30 minutes. The API structure is intuitive and well-documented. We provide detailed migration guides, code examples in multiple languages, and our support team is available 24/7 to assist with any technical questions.
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. For businesses processing high volumes, we can create custom enterprise plans that maximize your savings.
Is there a minimum commitment or contract?
No, EmailVerify offers pay-as-you-go pricing with no long-term contracts. Credits never expire, giving you complete flexibility. Unlike Kickbox's 6-month expiration policy, you can use your credits whenever you need them without pressure.
Can I export my verified lists from Kickbox and import them to EmailVerify?
Yes, you can export your verified lists from Kickbox and upload them to EmailVerify for re-verification or storage. We support all major file formats (CSV, Excel, TXT, JSON) and provide automatic duplicate removal to streamline the process.
How does the global infrastructure benefit my business?
EmailVerify's global CDN with 15+ regions means faster response times regardless of where your users are located. If you have customers in Asia, Europe, or Australia, our distributed infrastructure provides consistently low latency (<300ms), compared to Kickbox's US and EU-only deployment.
What if I need real-time list monitoring?
EmailVerify offers real-time email list cleaning and monitoring capabilities that automatically detect when email addresses become invalid or risky. Kickbox doesn't offer this feature, meaning you'd need to manually re-verify lists periodically, which can lead to deliverability issues.
