For SaaS Reseller Platforms
The email and phone API
that doesn't make you look bad
When contact data fails, your users blame you, not your provider. We find and verify in one step in real-time, so your product delivers reliable results fast.
Trusted by 50+ SaaS platforms to power contact enrichment with a <5% bounce rate guarantee
Why FindymailPower your product with reliable B2B data
Verify contact data others skip, deliver results faster than competitors, and get one reliable API with transparent pricing.
Give users the most reliable email data available
Your users need email data they can trust. We're the only provider guaranteeing <5% bounce rate while delivering the best email coverage in the industry, so they reach more decision-makers with confidence.
Keep your product fast
Slow enrichment kills momentum and requests time out or return incomplete data.
Our API returns results fast with better coverage, so your users' workflows keep moving.
One API for everything
Right now you're probably managing separate providers for emails, phone numbers, and company data. Different rate limits, different error codes and different pricing.
We handle it all in one API: email finding, verification, phone enrichment, company lookup, and reverse search.
Built for reliability
When your API goes down, your users can't work and problems land in your support queue.
We maintain 99.9% uptime, handle 300 concurrent requests, and verify in real-time so you never serve stale data.
Support that actually helps
API issues need real technical support, not canned responses.
Get the right answers fast from our support team: through chat, email, or direct Slack access, plus clear documentation.

Common questions from technical teams
Here are the most common ones we get.
Most endpoints return results in under 2 seconds. Email verification happens in real time, and our phone enrichment averages 8 seconds or less. One customer saw enrichment speeds improve by 41% after switching to us.
Most endpoints support 300 concurrent requests. Phone finding (via social profile URL) is limited to 30 concurrent requests when used synchronously. Domain search is limited to 5 concurrent requests for sync calls, but you can use webhooks for async processing with higher volume.
Simple: 1 credit per email found and verified, 10 credits per phone number. Email verification alone uses 1 verifier credit. You only pay when we successfully find data. Track usage in real time via the API so you always know where you stand.
Yes. Most endpoints support webhook URLs so you can submit requests and get notified when results are ready. This is especially useful for bulk operations or domain searches that need more processing time.
99.9% uptime. We verify data in real time instead of serving from stale databases, so you're never dealing with outdated information that breaks your users' workflows.
One of our customers (a prospecting platform) saw a 100% increase in phone enrichment coverage after adding us to their stack. We verify mobile numbers in real time, which is why results are both faster and more accurate than database-only providers.
Bearer token authentication. You can retrieve your token from the API page in your dashboard. Same token works across all endpoints with consistent error handling.
Yes. You can use our contact list management endpoints to organize and process contacts in bulk, or use webhooks for async batch processing. Intellimatch also supports exporting up to 5,000 companies per search.
You can, but most customers replace their waterfall entirely. We find and verify in one step with better coverage than stacking multiple providers. One API means no conflicting error codes or rate limits to manage.
We guarantee a <5% bounce rate. If emails bounce, we refund your credits. That's why platforms trust us as their primary provider instead of a backup option.
We verify catch-all emails in real time instead of marking them as "risky." That's why Clay's independent benchmark ranked us #1 with 23% more valid emails than competitors. Your users can reach decision-makers at enterprise companies that other tools skip.
Yes. OpenAPI 3.0 spec with working code examples for every endpoint. Clear rate limits, consistent error handling, and real examples you can test immediately. You can view it here.
Most teams are up and running in a few days. Our engineering team walks you through implementation, reviews the docs with you, and helps plan your rollout. No complicated onboarding or downtime.
Yes. Connect to our endpoints and run real requests from your use case. Compare coverage, speed, and accuracy against your current provider with actual data.
