ASOasis Tech Launches Email Verification Pro API—Multi-Layer Checks with Deliverability Scoring

ASOasis Tech ships an email verification API that goes beyond syntax checks

ASOasis Tech has released the Email Verification Pro API, a managed API that validates email addresses through seven distinct checks and returns a 0–100 deliverability score. The API is now live on RapidAPI and on the ASOasis product page.

What it does

The API exposes three endpoints:

• POST /v1/verify — Verify a single email address
• POST /v1/verify/batch — Verify up to 10 email addresses in one request
• GET /v1/health — Service health check

Each verification runs seven checks and returns:

• Syntax validation (RFC 5322 compliant)
• Disposable domain detection across 1,000+ known providers
• Role account detection (admin@, info@, support@, etc.)
• MX record verification with exchange server details and priorities
• SPF, DMARC, and DKIM authentication record checks
• Deliverability score from 0 to 100
• Verdict: deliverable, risky, unknown, undeliverable, or disposable

Why it matters

Invalid and disposable email addresses cost businesses money through wasted sends, damaged sender reputation, and inflated contact databases. Traditional approaches—regex-only validation or invasive SMTP probing—are either too shallow or too aggressive. The Email Verification Pro API provides a balanced, non-invasive alternative that checks multiple layers without touching the recipient’s mailbox.
