[02.b] methodology
How the benchmark is built
- Build the benchmark from real B2B users who are already associated with active customer or workspace usage, rather than from synthetic contacts or guessed email patterns.
- Use only contacts where we have a trusted source of work-email truth, then compare provider output against that known work email.
- Keep the benchmark public while keeping the underlying identities private: raw emails and person-level evidence are not exposed in the site output.
- Give each provider the same inputs within each input set so the comparison stays fair.
- Run each provider once per contact and store the returned work email candidate.
- Score correct emails against known work emails, then track wrong email rate, answer rate, and cost.
- Estimate cost from the cheapest public monthly plan and documented work email credit usage where public pricing exists.
