FAQ
Everything you might be wondering
What exactly do I get by reserving a spot now?
You get 1,000 verification credits free at launch, first time 50% discount on every paid plan, day-one API access, a 1:1 onboarding call with our team, and a founding-user badge with direct input on the roadmap. We’re capping this at the first 500 users.
Do I need to pay anything today?
No. Reserving is free and no payment information is required. You’ll only be billed if you upgrade beyond your free 1,000 credits after launch — and first time 50% off is already locked in if you do.
How is Email verifier different from Hunter, Kickbox, or ZeroBounce?
Three things. First, accuracy: our 99.8% SMTP-level verification is among the highest in the category. Second, transparency: every result ships with a confidence score so you can set your own risk threshold. Third, price: founding users lock in 50% off for first time — no one else will pay this rate
Is Email verifier GDPR and CCPA compliant?
Yes. We strictly adhere to GDPR, CCPA, CAN-SPAM, and ACMA regulations. We process data securely and offer minimal data retention by default.
What happens to the credits I don't use right away?
Your 1,000 launch credits don’t expire as long as your account is active. Use them at any time across single verifications, bulk CSV jobs, or API calls.
Can I integrate Email verifier with my CRM or sending tool?
Yes. We’re shipping with a REST API, async bulk endpoints, and CSV import/export. Native integrations with HubSpot and Salesforce are on the post-launch roadmap — founding users get to vote on the order.
What if I change my mind?
There is zero obligation. If you reserve a spot and decide Email verifier isn’t for you, you can simply walk away.
