How Our Engine Protects Your Inbox
Every address runs through a multi-stage verification pipeline before it ever reaches your sending platform.
Syntax & format check
Instantly drops malformed addresses — missing @ symbols, illegal characters, broken TLDs and typo domains like @gmai.com.
Spam trap & honeypot detection
Identifies addresses seeded by ISPs and blocklist operators specifically to catch senders mailing unverified lists.
Disposable email filter
Flags temporary and burner services such as TempMail and GuerrillaMail before they inflate your list and tank engagement.
Real-time SMTP ping
Checks mailbox existence at the receiving server without ever sending an actual email — zero risk to your domain.
Catch-all & MX verification
Pinpoints server responses to isolate catch-all and risky domains, so you can segment them instead of blindly mailing them.
Role & complainer suppression
Strips role accounts and known complainer addresses that generate abuse reports and drag your sender score down.
Automation That Thinks Ahead of Your Send
Machine learning layered on top of raw verification — so you know how a campaign will land before you launch it.
Dynamic bounce prediction
Machine learning models analyze domain health to predict deliverability scores before your campaigns launch.
Automated list repair
Generates suggested fixes for common typo domains — auto-correcting john@gmial.com to john@gmail.com instead of discarding a real subscriber.
AI deliverability consultant
Built into the Professional and Enterprise dashboard, giving actionable guidance on email copy and DNS setup — SPF, DKIM and DMARC.
