Where they pull apart

Debounce

Stands out: A verification API with a public per-check floor and a free start, so no $35/mo gate if your list is small.

Watch out: Per-check looks cheap until you run a million rows. There is no timed trial; free credits are the on-ramp.

Not the right fit for

  • People who need a finder
  • Teams that want a sequencer
  • Buyers who need a flat $32/mo all-you-can-verify

ZeroBounce

Stands out: Validation plus quality scoring on one meter, with a real free 100-credit allowance and a public $99/month subscription.

Watch out: Pay-as-you-go starts at $39 for 2,000 validations if you do not want a subscription. Heavy lists will burn the 10,000-credit ONE cap.

Not the right fit for

  • Teams that needed a finder, not a verifier
  • High-volume senders who will outgrow 10k/month immediately

Pros and cons

Debounce

  • Public per-check price
  • Free credits, no card
  • API-first list cleaning
  • Not a finder
  • Per-check math hurts at huge volume unless you buy packs
  • Thin ATS-style connector story

ZeroBounce

  • Public $99/mo ONE plan for 10k validations
  • 100 free credits, no trial needed
  • API plus MCP
  • ONE's 10k cap is easy to blow on a big agency list
  • Does not find emails, only validates them
  • Pay-as-you-go $39 pack is easy to miss if you only look at $99
