# Reverse email lookup
> Resolves an email address to the most probable Specter person, returning their person ID, core profile fields, and a match confidence score. Use `person_id` with [Get person info by ID](/api-reference/people/get-person-info-by-id), or `company_id` with [Get company by ID](/api-reference/companies/get-company-by-id).
Costs 1 credit per request.
## Behaviour
- `score` ranges from 1 to 10. A score of 7 or higher is generally a reliable match; treat lower scores with increasing caution.
- Returns `204` if the email can't be matched to a person.
