How Contact Enrichment Works for Recruiters

Recruitment contact enrichment typically uses a multi-provider waterfall: the system queries cached data first (free), then premium providers in sequence until a verified result is found. This approach minimises cost while maximising coverage. A typical waterfall checks company records, then email pattern databases, then phone directories, then live verification services.

The enrichment process for a single contact usually takes 2-5 seconds and follows this sequence:

  • Cache check — previously found data is returned instantly at zero cost
  • Email pattern matching — generates likely email patterns (first.last@, f.last@) and verifies via SMTP
  • Provider lookup — queries data providers for verified email and phone
  • Verification — validates email deliverability via MX record and SMTP checks

Email Enrichment vs Phone Enrichment

Email and phone enrichment have different coverage, verification and credit costs. Test both on a representative list; no universal Australian success rate is established here.

Choosing an Enrichment Provider for Australian Recruitment

Australian-specific considerations when choosing enrichment tools:

  • +61 number coverage — many US-built tools have poor Australian mobile number coverage
  • Toll-free filtering — reject 1800/1300 numbers that reach switchboards, not decision-makers
  • ASIC/ABR integration — Australian company data from government registries is more reliable than scraped sources
  • Verification accuracy — check provider claims against your own domain; catch-all domains inflate reported accuracy
