ContactThe only validator that resolves catch-alls instead of guessing
Standard validators punt on catch-all domains and hand you “unknown.” We go deeper and resolve many of them — so your B2B lists come back usable. Start free, pay as you go with credits, or go unlimited.

Frequently asked questions
Can't find the answer you're looking for? Reach out to our customer support team.
- Should I buy credits or go Unlimited?
- Credits are pay-as-you-go — best for one-off cleans or occasional validation. Unlimited is a flat monthly rate with no per-email charges — best once you validate regularly or in high volume. You can always start with credits and switch to Unlimited later.
- Do credits expire?
- Credits never expire. 1 credit validates 1 email with a definitive verdict, and you can use them for bulk lists or the API.
- How does catch-all resolution work?
- Most validators return "unknown" on catch-all domains and leave you guessing. We go further with enhanced validation to resolve many of those addresses. It runs automatically only where standard validation returns "unknown", and costs 3 credits per resolved address — so you never pay extra on the easy ones. Every Unlimited plan includes a monthly allotment of enhanced resolutions.
- What does "unlimited" actually include?
- Unlimited means no volume cap and no per-email charges for standard validation. Plans are sold as 3, 6, or 12-month commitments billed upfront — the longer the commitment, the lower the monthly rate. Every Unlimited plan includes API access, integrations, unlimited team members, 10,000 enhanced catch-all resolutions per month, and deliverability monitoring (25 domains + 50 sending IPs).
- What's included in Enterprise?
- Enterprise starts at $2,000/mo and includes everything in Unlimited plus an SLA with uptime guarantee, a SOC 2 Type II report, SAML/SSO, dedicated support, white labeling, and custom throughput. Contact sales for a quote.
- Can I change my plan later?
- You can start with credits and upgrade to Unlimited at any time. Term changes take effect at renewal — if you need to change a commitment mid-term, contact us and we will sort it out.
- What payment methods do you accept?
- All major credit cards through our secure payment processor, Stripe.
