  • VAT invoice
  • 1 credit = 1 email

How much does email verification cost?

One credit = one verification. Buy a pack once, credits never expire. No monthly subscription or hidden limits — you pay only for checks you actually use.

Self-serve: create an account, upload a list or connect the API without a sales call.

Pay-as-you-go model

You pay for verifications used, not for unused subscription capacity. Credits stay on your account with no expiry — seasonal campaigns do not waste unused monthly limits.

Comparison with subscriptions

Verifiers with monthly limits often waste budget off-season. With us you buy exactly what you need, and larger packs lower the per-address price.

ROI vs cost of hard bounces

One hard bounce on a large list hurts domain reputation and ESP support time. Pre-send verification costs a fraction of that risk — especially for cold email and old databases.
