Pricing
Credits for cleaning lists. Plans for watching domains.
Two separate things, priced separately, so you only pay for the one you need. Validation credits are pay-as-you-go and never expire. Deliverability tools are a small monthly plan, with a free tier that stays free.
Validation credits
Pay as you go. Credits never expire.
One credit per email verified, whether the answer is valid, invalid or risky. No subscription, no minimum, no expiry date.
