CandidateIQ vs ZeroBounce

Same facts, side by side: starting price, free tier, MCP, API and what each one is actually built for.

Starting price

CandidateIQ

$200/mo Free trial

Data clean-up for staffing firms whose ATS is full of dead emails and stale records. CandidateIQ validates contact details, enriches records with titles, locations, social profiles and resumes, and gives each candidate a Trust Score so recruiters and automations work the reachable records first. Plans start at $200/mo or $2,500 per project, and Bullhorn users can run it as a managed sync from $1,000/mo.

Where CandidateIQ fits

  • Staffing firms on Bullhorn with large, ageing databases
  • Agencies preparing data before rolling out AI matching or automation
  • Ops teams fighting bounced emails and dead numbers
  • Firms that want a one-off database clean-up project

ZeroBounce

$39/2,000 credits Free tier

Email validation and scoring. Free 100 credits; ZeroBounce ONE starts at $99/mo for 10,000 validations.

Where ZeroBounce fits

  • Recruiting and sales teams cleaning lists before send
  • Ops that want validation as an API
  • Desks that need scoring, not only deliverable/undeliverable
  • Buyers who want a no-commitment free 100 credits

Where they pull apart

CandidateIQ

Stands out: It treats your existing database as the asset: rather than buying new candidates, it scores, verifies and fills in the ones you already own, then writes the results back into Bullhorn fields. You can test it free on your own records before paying.

Watch out: Only Bullhorn gets a named, managed integration; other ATSs work through file uploads or the API on the Enterprise plan. The useful real-time sync starts at $1,000/mo, and it improves data rather than doing any outreach itself.

Not the right fit for

  • Small desks with a few thousand clean records
  • Recruiters who want an email finder for new prospects

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

ZeroBounce

  • 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
