The Enrichley API focuses on one thing: high-quality email validation, with a special emphasis on validating catch-all and other “risky” email addresses. Instead of throwing away those addresses, Enrichley helps you safely recover more of your list and protect your sender reputation.
Key features
Email validation for real-world lists
- Validate individual email addresses through the API.
- Detect and handle catch-all domains so you don’t need to discard them by default.
- Designed to keep bounce rates low while maximizing the number of usable contacts.
Benefits
Recover more valid emails
On many unverified lists, 40–60% of emails are considered “risky” because they’re on catch-all domains. Enrichley is designed to safely recover a large portion of those addresses, often resulting in 20–30% more valid emails on the same list compared to traditional verification tools.
Protect sender reputation
By validating emails before you send, you reduce hard bounces and help keep your sending domains and IPs healthy. Enrichley’s real-time checks are tuned to help keep bounce rates low when used with clean data sources.
Use your data more efficiently
Data is expensive. Rather than discarding a large percentage of your list due to catch-all results, Enrichley lets you keep more of the prospects you’ve already paid to acquire.
Use cases
- Sales & marketing teams – Clean prospect lists before campaigns and preserve valuable catch-all leads instead of deleting them.
- Email deliverability & ops – Monitor list quality across different sources and maintain strong sender reputation.
- Product & engineering teams – Integrate validation checks directly into signup flows, CRMs, and internal tools via the API.
Enrichley’s API is designed to be straightforward for developers while giving growth teams the confidence to send to more of their list.
