Single-source tools miss contacts. We don't.
Most email list cleaning tools check one database. If your contact isn't there, you get nothing. Cleanlist uses waterfall enrichment — we query 15+ data providers in sequence until we find a match.
Waterfall Enrichment Flow
Other tools stop at Provider 1. Cleanlist keeps going until we find a match.
Verification
Our email verification process runs every address through three rigorous validation steps before marking it deliverable.
Syntax Check
Validates email format, checks for typos, and normalizes the address according to RFC 5322 standards.
- RFC 5322 compliance
- Domain format validation
- Local part verification
- Common typo detection
MX/DNS Validation
Queries DNS records to verify the domain exists and has valid mail exchange (MX) servers configured.
- MX record lookup
- DNS resolution check
- Mail server discovery
- Domain age verification
SMTP Handshake
Performs a real-time ping to the mail server without sending an email to verify the mailbox exists.
- Real-time server ping
- Mailbox existence check
- Catch-all detection
- Greylisting handling

Frequently Asked Questions
How does Cleanlist's email verification tool work?
+
Cleanlist's email verifier uses triple-layer email validation: syntax check (RFC 5322 compliance), DNS/MX record lookup (domain exists and accepts email), and SMTP handshake verification (mailbox exists). We also detect catch-all domains, disposable emails, role-based addresses, and spam traps.
What's reverse email lookup? How do I get contact data from just emails?
+
Reverse email lookup takes an email address and finds the person behind it. Cleanlist searches 15+ data providers to find their direct phone number, company name, job title, LinkedIn profile, location, and more. Upload a list of emails — we return a complete contact database.
How many data providers do you check?
+
Cleanlist uses waterfall enrichment across 15+ premium data providers. We query each provider in sequence — if the first doesn't have a match, we check the next, and the next. This is why we achieve 98% match rates where single-source tools top out at 60-70%.
Can I do bulk email verification and enrichment?
+
Yes. Our bulk email verification tool handles CSV files with up to 10,000+ emails per batch. Cleanlist verifies each email through all three validation layers AND enriches every contact with phone, company, title, LinkedIn, and more. Email list cleaning at scale typically completes within minutes.
Is there a free email verification tool I can try?
+
Yes. Cleanlist offers free email verification with 30 credits per month — no credit card required. Each credit verifies and enriches one contact. Paid plans start at $29/month for 500 credits if you need to clean larger email lists.
What accuracy rate does your email verifier achieve?
+
Cleanlist's email verification tool achieves 99.9% deliverability on verified emails. Our triple email validation process catches invalid, risky, and undeliverable addresses before you send, reducing bounce rates to under 1%.
