ZeroBounce bundles validation with email finding, blacklist monitoring, warmup and inbox testing. That is great if you need all of it, but it shows up in the price. If your job is simply to know which addresses are safe to send, you are subsidising features you will never open. Email Verifier API does one thing, accurate verification, and prices accordingly.
ZeroBounce advertises 100 free monthly validations, but its own pricing page conditions that on signing up with a business or premium domain. Our 100 free credits come with every account, with no domain check and no card.
ZeroBounce markets around 99%. An independent test of 563 addresses by Sparkle measured 96 to 97% in the real world. Our engine targets 98% using a live 16-point check, including a real SMTP handshake that never sends a message.
