Email Verification API — Validate Any Email Address in Real-Time
Free email verification API with syntax check, MX record lookup, disposable domain detection, role account detection, typosquat correction, and deliverability scoring. Validate any email address in real-time.
What is Email Verification?
Email verification is the process of validating whether an email address is valid, deliverable, and safe to send to. APImcp.site's email verification API performs comprehensive checks including syntax validation, MX record lookup to confirm the domain accepts mail, disposable email domain detection, role account detection (admin@, info@, etc.), typosquat domain detection, and a deliverability score. No email is actually sent — all checks are performed via DNS and pattern analysis.
How to Use the Email Verify API
Call GET /api/v1/email-verify?email=user@example.com. The API returns a JSON response with valid (boolean), score (0-1), syntax_valid, mx_found, disposable, role_account, typosquat_domain, free_email, and error flags. The score aggregates all checks into a single deliverability confidence metric.
Key Features
Syntax validation against RFC 5321/5322. MX record lookup via Cloudflare DNS-over-HTTPS. Disposable domain database with 10,000+ known domains.
