Run your list through 8 verification providers before you hit send. Catch the invalids, catch-alls, and disposables that single-provider tools miss.

No credit card required. Results in under 60 seconds.

The silent campaign killer nobody talks about

You spent hours building the perfect list. Wrote great copy. Set up your sequences. Then 8% of your emails bounce and your domain ends up in spam for the next three months.

Single-provider verification
  • Misses 15-20% of bad addresses — one API can't see everything
  • Catch-all domains marked 'valid' when they're actually dead
  • No way to know if a 'risky' result is truly risky or just uncertain
  • Disposable/temp emails slip through — they bounce 48 hours later
  • You find out your list was dirty after your domain gets flagged
Multi-provider consensus
  • 8 providers cross-check every address — if one misses it, another catches it
  • Catch-all detection actually works because multiple providers triangulate
  • Consensus scoring: 'valid' means 2+ independent services agree
  • Role accounts (info@, support@) flagged automatically
  • ISP detection tells you which mail servers you're sending to

Here's exactly how it works

Three steps. Clean list. Protected domain.

1
Upload your list

Paste emails, upload a CSV, or verify one at a time. We accept lists of any size — no artificial caps.

2
We check 8 providers

Each email runs through multiple verification services in parallel. Results are cross-referenced for consensus. The whole process takes seconds per email, not minutes.

3
Send with confidence

Get a clean list with clear status labels — valid, invalid, risky, catch-all. Remove the bad ones. Keep your bounce rate under 2%. Your domain stays clean.

What your results look like

Email Status Providers Type Details
[email protected] Valid 3/3 agree Business Google Workspace
[email protected] Role Flagged Role account Generic address — low reply rate
[email protected] Invalid 3/3 agree Defunct MX records missing, domain expired
[email protected] Catch-all Detected Business Domain accepts everything — verify manually
[email protected] Invalid 2/2 agree Disposable Temporary email service — will bounce

Every result includes the raw response from each provider — full transparency, no black boxes.

Here's what you get under the hood

Every angle covered

Most tools check one thing. We check all of them.

Consensus Verification

Two or more providers must agree before an email is marked valid. Single-provider false positives drop to near zero. When providers disagree, you see exactly who said what — and you decide.

Catch-All Domain Detection

Catch-all domains accept every email address — even fake ones. Most verifiers mark them "valid." We detect catch-all domains at the domain level and flag every address on them so you don't waste sends on addresses that look good but go nowhere.

Role Account Flagging

Addresses like info@, support@, and sales@ are technically valid but almost never lead to replies. We flag them separately so you can decide whether to include them or skip them entirely.

Real-Time Progress Tracking

Watch results stream in as each email gets verified. No uploading a file and checking back tomorrow. You see status, provider responses, and completion percentage live as it runs.

ISP & Mail Server Detection

Know whether you're sending to Google Workspace, Microsoft 365, or a self-hosted server. Different providers have different spam thresholds — this tells you what you're dealing with before you send.

The real difference is what happens when providers disagree

Every tool on this list verifies emails. The question is how many angles they check and what happens with the gray areas.

According to EmailToolTester , single-provider accuracy ranges from 85-95%. Consensus across multiple providers pushes accuracy above 99%.

Why I built this

I was running a cold email campaign — 3,000 contacts, carefully segmented, personalized subject lines, the works. I verified the list with one of the big-name tools. It said 96% valid. I sent it.

240 bounced. My bounce rate hit 8%. Within 48 hours, Google flagged my domain. Every email from my company — sales, support, invoices — started landing in spam. It took three weeks to recover.

When I dug into the bounces, the pattern was clear: catch-all domains marked "valid," role accounts that never reply, and a handful of disposable emails that died between verification and sending. One provider couldn't see any of this.

So I started cross-referencing. Run the list through two providers. Then three. Then five. The results were night and day. Emails that one service called "valid," two others flagged as risky. Catch-all domains that one tool missed, three others caught.

That's what this is. Not another single-provider verifier. A consensus engine that treats email verification the way credit agencies treat your credit score — multiple independent sources, and you only trust the answer when they agree.

Common questions

Each provider has different detection methods, different databases, and different blind spots. One might miss catch-all domains. Another might miss disposable addresses. Cross-referencing eliminates the gaps. It's the difference between 90% and 99.7% accuracy — and that 9.7% is exactly the emails that will tank your deliverability.

Single emails verify in under a second. Bulk lists process at roughly one email per second with real-time progress streaming. A 1,000-email list takes about 15-20 minutes. You don't have to wait — results stream in as each email finishes, and you can start working with the clean portion immediately.

A catch-all domain accepts email sent to any address — even fake ones like [email protected]. Most single-provider verifiers mark these as "valid" because the domain accepts the email. But that doesn't mean a real person reads it. We detect catch-all domains at the domain level and flag every address on them, so you can make an informed decision about whether to include them in your campaign.

Verification results are cached for 60 days. If you verify the same email within that window, it's instant and free — no credits used. After 60 days, we recommend re-verifying since email addresses change. People leave companies, domains expire, servers change — a valid email today might bounce next quarter.

Yes. Verification is built into the lead pipeline — find leads, enrich them, verify emails, and push to outreach campaigns without leaving the platform. You can also use it standalone: upload a CSV, get a clean list back, export it. Works both ways.

Every email gets one of five statuses: Valid (safe to send), Invalid (will bounce), Risky (might bounce — up to you), Catch-all (domain accepts everything), or Role (generic address like info@ or support@). Each status includes the raw response from every provider that checked it, so you always know why it was classified that way.

Start free — your first batch costs nothing. After that, pay per verification with volume discounts. It's a fraction of what a single bounced campaign costs you in domain reputation damage. And with 60-day caching, you never pay twice for the same email.

Every bounced email is a crack in your sender reputation. The cracks add up faster than you think.

It takes three weeks to recover from a blacklisted domain. It takes 60 seconds to prevent it.
