How this service works
Find the most likely deliverable work email for a person. Provide first_name, last_name, and company_domain, or a LinkedIn person or company URL and the identity is resolved automatically. Builds ranked candidate patterns and probes them over SMTP, with catch all detection. Results are cached per name and domain so repeat lookups are instant and free. Billed only on status found.
Output
Returns the most likely deliverable work email address for the person, along with a deliverability status (e.g. found, risky, catch-all, invalid) and confidence ranking. Results are cached per name and domain for instant repeat lookups. Billing only occurs when status is 'found'.
Example use cases
Sales outreach contact discovery
“I need to reach out to Marcus Rodriguez who works at stripe.com — can you find his work email so I can send him a cold email?”
LinkedIn lead email lookup
“I found a promising prospect on LinkedIn at linkedin.com/in/james-holloway-marketing — can you find his deliverable work email address?”
CRM contact enrichment
“I have a lead: first name Emily, last name Watts, company domain hubspot.com — what's her most likely work email I can add to our CRM?”
Technical details
Endpoint
POSThttps://bytemine.pay.zeroclick.io/functions/v1/api-gateway/email-finder?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a single, deliverable work email for a known person at a specific company and want SMTP-verified accuracy rather than a raw guess. Prefer it over bulk email finders when precision matters and you are billed only on confirmed finds. It is especially useful when you have a LinkedIn URL and want automatic name and domain resolution without pre-formatting inputs.
Side effects
- No email found if the person does not exist at the domain or patterns cannot be verified
- Catch-all domain detection may limit confidence — email returned as risky rather than verified
- Invalid or non-existent LinkedIn URL causes resolution failure
- Missing required fields (no company_domain and no linkedin_url) returns a validation error
- SMTP probing may be blocked by strict mail servers, reducing deliverability confidence
