Tariff
Priced by what you actually verify.
Credit-based, no seat tax, no overage trap. Credits never expire and roll between bulk and API usage interchangeably.
Frequently asked
- Do credits expire?
- No. Credits roll over month to month and can be used interchangeably between bulk uploads and the real-time API.
- What counts as a credit?
- One credit per definitive verification answer (valid, invalid, risky, role, catch-all). Transient SMTP errors are free retries.
- Can I change plans?
- Anytime. Upgrades are prorated immediately; downgrades take effect at the next billing cycle.
- Is there a free tier?
- Yes — 25 free AI-scored verifications per day, no credit card required, for as long as you want.
- Is the decision engine included on every plan?
- Yes. Every plan — including the free tier — gets the full decision engine: a confidence score, bounce risk, recommended action and machine-readable reason codes on every result.
- Does it get more accurate over time?
- Yes. When you report real delivery outcomes (or wire up your email provider's bounce webhook), the engine refines its per-domain and per-address scoring — so catch-all and unknown domains keep getting sharper.
