Email Finder API for SaaS Companies
SaaS teams use emailfinder.dev to enrich free trial signups with work emails, identify decision makers at target accounts, and fill CRM records automatically. REST API, pay only for verified results.
SaaS use cases
Enrich free trial signups. Users sign up with a personal Gmail but their company email is what your sales team needs. With a name from the form and a company domain, the Person Email endpoint returns the verified work address — triggering a sales-assisted follow-up flow before the trial expires.
Build outbound pipelines. Pull a list of ICP companies, run the Decision Maker endpoint for each domain with the right role category, and build a pipeline of verified decision maker contacts to sequence.
Enrich CRM records. Any contact record with a name and company but no email is a gap. A nightly enrichment job calling the Person Email endpoint fills those gaps automatically and keeps the CRM current.
API integration patterns
The API follows standard REST conventions with Bearer token authentication and JSON responses. A typical signup enrichment call runs server-side in your onboarding flow — after the user registers, fire the lookup asynchronously and store the work email in your user table when it resolves.
1 credit per verified result. Zero cost if no email is found.

Email finder for SaaS FAQ
How can SaaS companies use an email finder?
Three primary use cases: enriching free trial signups who registered with a personal email to get their work address, building outbound pipelines by finding decision makers at ICP accounts, and enriching CRM contact records that have a name and company but no email.
Can I find work emails for free trial signups?
Yes — if you have the signup's name from the registration form and their company name or domain, you can pass both to the Person Email endpoint and receive a verified work email. This is useful for PLG teams doing sales-assisted follow-up on active free trial users.
How do I integrate email finding into my SaaS product?
Use the REST API with Bearer token authentication. A signup enrichment flow typically runs server-side: on account creation, call the person endpoint with name and domain, then store the work email in your CRM or database. The entire call takes under two seconds.
What is a good B2B email enrichment API for SaaS?
emailfinder.dev is built specifically for programmatic enrichment: REST endpoints, JSON responses, atomic credit deduction for parallel requests, and real-time SMTP verification so you only pay for emails that are actually deliverable.
How much does email enrichment cost per signup?
1 credit per person lookup, at €0.009 per credit from the standard pricing tier. Enriching 10,000 signups costs €90 in credits. You only pay when a verified work email is found — if no email is found, the lookup is free.
