“Valid” is the most expensive
lie in cold email.
Most verifiers flag catch-alls as risky and leave you guessing. VerifyHQ resolves them to actual mailbox validity so you never lose a good lead or torch a domain again. Send with proof, not hope.

Works with your favorite outreach stack
Real-time single verification
Paste one email. Get a tier, score, and reason in under 2 seconds. Embed in signup forms, plug into your CRM, or check straight from the dashboard.
Bulk list cleaning
Upload CSVs up to 500K rows. Download cleaned results with industry-standard field names — drop straight into your existing workflow.
Catch-all resolution that actually works
Other verifiers see "catch-all" and shrug. VerifyHQ digs deeper — resolving catch-all domains to actual mailbox-level validity so you stop throwing away perfectly good leads.
Deliverability scoring
No more binary "valid/invalid." Every email gets a deliverability score you can threshold — send above 80, review 50–80, skip below 50. Your rules.
Native integrations & API
Native integrations with Instantly, Smartlead, Lemlist, Apollo, HubSpot, ActiveCampaign, Zapier, and more. RESTful API with async webhook callbacks signed with HMAC-SHA256 — drop verified data exactly where your stack needs it.
Actionable reports & exports
Filter by tier, score, domain, or provider. Export clean CSVs with industry-standard attributes. Spot domain-level patterns before they torch your deliverability.
Testimonials
Teams that send smarter, not harder.
We switched from ZeroBounce and our bounce rate dropped below 0.4% immediately. The catch-all resolution is in a league of its own — we stopped losing perfectly good leads on catch-all domains entirely.
Jake Morrison
Head of Growth, Outbound Labs
VerifyHQ's deliverability scoring changed how we build lists. We set our send threshold at 80 and haven't had a bounce problem since. It's the one tool I'd rebuild my entire cold email stack around.
Sarah Chen
Founder, ScaleReach
Running 15+ client campaigns simultaneously means one dirty list can torch multiple domains. VerifyHQ is the only verifier we trust to catch what everyone else misses. Non-negotiable for our agency.

Built-in Protection — Included, Not Upsold
Blacklist monitoring
Daily automated checks against major blocklists. The moment your domain or IP gets listed, you'll know — and you'll know the second it clears.
Abuse detection
Every email is cross-referenced with known spammer databases. Addresses linked to abuse get flagged and scored down before they touch your campaign.
Toxic domain detection
Catches domains used for phishing, malware, and botnets. Identified inside the pipeline — killed before they ever reach your list.
Use Cases
From your first submission to your millionth cold email.
Whether you're checking one address at signup or cleaning a bought list of 200K leads — VerifyHQ handles it.

Start small. Scale cleanly.
Block bad emails at the door

Got questions? Straight answers only.
99%+ accuracy across our multi-stage deep pipeline. Every address runs through syntax, DNS, SMTP, spam trap, catch-all resolution, and deliverability scoring on our own dedicated infrastructure — not a resold third-party API.
A score that tells you how confident we are this email will land in an inbox. It factors in mailbox existence, domain health, catch-all status, spam trap signals, and abuse history. Set your own send threshold and skip the guesswork.
