API Documentation

The 16-Point Verification Engine

Every email request undergoes a rigorous 16-stage inspection. We don't just check if the mail exists; we analyze the health, risk, and intent of every address to maximize your ROI.

01. Syntax Check

Verifies RFC compliance to catch typos and invalid formatting instantly.

02. SMTP Handshake

Pings the mail server in real-time to confirm the mailbox actually exists.

03. MX Records

Confirms the domain has valid mail exchange records to receive messages.

04. DNS Validation

Verifies the domain is active and correctly configured on the global internet.

05. Spam Traps

Identifies honeypots and blacklisted addresses before they hit your sender score.

06. Complainers

Flags users known for marking emails as spam to keep you off global blacklists.

07. Greylisting

Detects temporary server defenses so you can manage retry logic efficiently.

08. Mailbox Full

Identifies accounts at capacity that will result in immediate hard bounces.

09. Typo Suggest

Detects domain misspellings and suggests the correct email in real-time.

10. Disposables

Block disposable email services used to bypass trials and commit fraud.

11. Role Accounts

Flags info@ or sales@ to help you prioritize personal professional contacts.

12. Catch-All

Detects 'accept-all' domains to help you manage delivery uncertainty.

13. Gibberish Detection

ML-powered detection of bot-generated keyboard smashes (e.g. asdf123@).

14. Offensive Content

Flags profanity or high-risk keywords to ensure brand safety and compliance.

15. B2B Lead Scoring

Instantly identifies Gmail/Yahoo vs. high-value corporate domain emails.

16. SMTP Provider

Identifies the host (Google, O365, etc.) for advanced list segmentation.
