From single checks to enterprise bulk processing — we cover every step of email verification.
SMTP Deep Validation
Connects to the recipient's mail server and performs a full SMTP handshake — the only way to truly know if a mailbox exists.
Bulk Excel Upload
Upload .xlsx with an Email column (any position — A, B, C, D…). Name, Company, and other fields stay in the file. Or paste 10–5,000 addresses. Color-coded Excel results when done.
Real-Time API
RESTful API with API keys. Integrate into your sign-up forms, CRM, newsletter tool, or any app. Rate limited, documented, reliable.
Disposable & Catch-All Detection
Instantly flag temporary emails (Mailinator, 10minutemail, etc.) and catch-all domains that accept everything — even non-existent addresses.
Email Scoring 0–10
AI-style composite quality score for every email. MX reputation, SMTP response quality, domain age — prioritize high-quality leads instantly.
Email Finder
Find verified emails by name and domain. Pattern generation + SMTP validation. Domain cache for instant repeat lookups. Perfect for outreach.
Blacklist Monitor
Monitor domains & IPs against 110+ DNSBLs (Spamhaus, Barracuda, SORBS). Auto-scans every 8h. Email alerts on reputation changes. Free — no credits used.
Typo Correction
Auto-detect typos like "gmial.com" → "gmail.com". Suggests corrections before SMTP check. Saves credits and catches user errors.
Beyond Verification — Deliverability & Monitoring
Protect your sender reputation, catch list decay, and validate phone numbers too.
DMARC Report Monitoring
Collect your DMARC rua aggregate reports and see every source sending as your domain — with SPF/DKIM alignment and message counts. Free: 1 domain.
Continuous List Monitoring
Subscribe a list and we re-verify it on a schedule, then alert you the moment a good address starts failing. Stop list decay before your next send. Free: 1 list.
Phone Validation
Check any phone number's line type and carrier (mobile, landline, VoIP). Offline format checks are free and unlimited; carrier lookups include a free monthly allowance.

Email verification checks if a mailbox actually exists (SMTP probe). Validation is just syntax checking. We do both.

Do catch-all checks cost credits?
No — catch-all detection, risky, and unknown results are free. You only pay for valid/invalid verdicts.
How fast is the API?
