How to choose
- Price the unit you actually use (per email verified (credit = 1 email); buyers compare $ per 1,000 verifications, credits-expiry, and free monthly credits), not the headline plan.
- Check what the free tier allows before paying: several options above list one.
- Test on your own data; switch costs are usually the data format and integrations, not the price.
