EmailLabs Email Verification API
EmailLabs verifies and scores any email address in milliseconds, running every meaningful deliverability check short of an SMTP probe — so you catch bad, fake, and risky addresses before they ever hit your database.
What it checks
gmial.com → gmail.com).What you get back
A single JSON response with a per-check breakdown, a 0–100 confidence score, and a clear verdict: valid, risky, or invalid — plus human-readable reasons for the result.
Why use it
Highlights
The Verify Email endpoint returns a JSON response containing the validation status of the email address, a confidence score, and a detailed breakdown of various checks performed, such as syntax, domain validity, disposable status, and typo suggestions.
Key fields in the response include "email" (the original email), "normalizedEmail" (formatted email), "status" (valid, risky, or invalid), "score" (0-100 confidence score), and "checks" (detailed results of each validation check).
The response data is structured in a JSON format with a top-level object containing the email details, validation status, confidence score, and a nested "checks" object that provides results for each specific validation check performed.
The endpoint provides information on email syntax validity, length limits, domain and MX record checks, disposable email detection, identification of free webmail providers, role-based account flags, and typo suggestions for misspelled domains.
Data accuracy is maintained through rigorous validation checks against established standards (RFC 5321 and RFC 5322), real-time DNS lookups for domain verification, and continuous updates to the database of disposable and free email providers.
Typical use cases include validating email addresses during user registration to reduce bounce rates, cleaning existing email lists, enhancing user experience with typo suggestions, and preventing fake sign-ups by identifying disposable addresses.
Users can customize their requests by providing a single email address to the Verify Email endpoint. The API automatically performs all relevant checks without requiring additional parameters, streamlining the validation process.
Standard data patterns include a clear "status" indicating the email's validity, a "score" reflecting confidence in the result, and detailed "checks" that provide insights into specific validation aspects, such as syntax and domain checks.
