Enrich leads the moment they arrive.

Incomplete leads cost you deals

A lead fills out a form with their name and company. Maybe they give you a personal Gmail address. Maybe they skip the email field entirely. Your sales team gets a notification, but they have no way to follow up effectively.

This happens constantly. Marketing generates the lead, but the data is too thin for sales to act on. The lead sits in a queue, ages out, and the opportunity disappears. The problem is not lead generation. The problem is lead data.

Manual enrichment does not scale. Having a rep Google every lead to find their work email takes time that should be spent selling. And bulk enrichment tools that rely on pre-built databases return stale data that bounces.

Enrichment that happens in real-time

emailfinder.dev resolves verified email addresses live. There is no database lookup, no cached result from last quarter. Every request hits the actual mail server and confirms the mailbox exists right now.

When a lead comes in with a name and company, you can immediately resolve their verified work email through the API. The response comes back in under 3 seconds, which means you can enrich leads as they arrive, not in a nightly batch job.

This is the difference between following up within minutes and following up days later with data you are not sure about.

Enriching from partial data

The Person Email endpoint accepts flexible inputs. You can pass a full name and domain, or first name, last name, and company name separately. This handles the messy reality of form submissions where data is inconsistent.

If you have a LinkedIn URL instead, the LinkedIn Lookup endpoint returns the verified email along with the person's current job title and company. This is useful when leads come from social channels or referral programs.

Discovering all contacts at a company

Sometimes a lead represents an account, not just a person. The Company Emails endpoint returns up to 20 verified email addresses for any domain. This lets you map the organization and identify additional stakeholders.

For account-based marketing workflows, this means you can go from a single inbound lead to a full account contact list in one API call. Route different contacts to different sequences based on their role.

Pay only for results that work

Credits are charged only when we return a verified, deliverable email address. If the lookup does not find a valid result, you pay nothing. This makes enrichment economically safe to run on every lead, even high-volume inbound.

There are no monthly minimums, no subscriptions, and credits never expire. You buy credits when you need them and use them at your own pace.

Integration patterns

The most common pattern is a webhook or serverless function that fires when a new lead is created in your CRM or marketing platform. It calls the emailfinder.dev API, gets the verified email, and writes it back to the lead record.

This works with HubSpot, Salesforce, Pipedrive, or any system that supports webhooks. For custom pipelines, the API is a simple GET request with JSON response, so integration takes minutes, not days.

With 1,000 requests per minute rate limit, you can handle traffic spikes from campaigns, events, or product launches without throttling.
