3-Level Email Validation With Quality Scoring
Clean your email lists with PMTAcore's powerful 3-level validation engine. Choose Basic (format, MX, disposable checks), Full (adds SMTP mailbox verification and catch-all detection), or Advanced (adds spam trap detection, DNSBL checks, reverse DNS, domain age analysis, and SPF/DMARC verification). Every email gets a quality score from 0-100. Multi-threaded batch processing handles thousands of addresses at once.

Validation Features
Powerful tools for cleaning and verifying your email lists
Multi-Threaded Batch Processing
Validate thousands of emails simultaneously with configurable thread count. Upload CSV or text files and process entire lists in minutes.
Quality Score 0-100
Every email gets a quality score from 0 to 100 based on all validation checks. Filter your lists by score threshold to keep only the highest quality addresses.
Disposable & Spam Trap Detection
Detects temporary email services like Guerrilla Mail and Mailinator. Advanced level also identifies known spam traps to protect your sending reputation.
SMTP Mailbox Verification
Connects to the mail server and verifies the mailbox exists without sending an email. Detects catch-all servers and handles greylisting responses intelligently.
Typo Suggestions
Automatically suggests corrections for common email typos (e.g., gmial.com → gmail.com). Recover valid addresses that would otherwise be lost.
