How this service works
Find and validate a work email from a name plus company domain.
Output
Returns the best candidate email address along with a status (found, guessed, not_found, skipped, or no_mx), a confidence level (high, medium, or low), SMTP verification result (valid, catch-all, or unknown), a catch_all boolean flag, a cached boolean indicating whether the result came from cache, and a credits_charged integer (1 if found, 0 otherwise).
Example use cases
Sales prospecting email lookup
“I need the work email for Marcus Rivera at stripe.com — find the most likely deliverable address so I can reach out to him directly.”
LinkedIn-based contact resolution
“I found this person on LinkedIn at linkedin.com/in/jane-doe-product — can you figure out their work email from that profile?”
CRM contact enrichment
“I have a lead named Tom Nakamura who works at datadog.com but I only have his name and company — can you find and verify his professional email address?”
Technical details
Endpoint
POSThttps://agents.bytemine.ai/functions/v1/api-gateway/email-finder?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a single verified work email for a named individual at a known company domain, especially for B2B outreach or CRM enrichment. It is preferable over generic email-guessing tools because it performs live SMTP verification with catch-all detection, caches results so repeat lookups are free, and charges only on a confirmed find. Use it when you have a person's name plus a company domain or LinkedIn URL and need the highest-confidence deliverable address available.
Side effects
- status: not_found — no matching email pattern could be verified for the given name and domain
- status: no_mx — the company domain has no valid MX records, so email cannot be delivered
- status: skipped — input was incomplete or the domain was blocked
- SMTP result: catch-all — domain accepts all addresses so deliverability cannot be confirmed
- Missing required fields — must provide either (first_name + last_name + company_domain) or a linkedin_url
- Invalid LinkedIn URL format — person URL required for automatic identity resolution
