Bulk Email List Cleaning
Don't let hard bounces drag your campaigns down
Even the best-planned campaign falls flat if deliverability is poor — and nothing kills deliverability like a dirty list. Upload yours and get back a clean, send-ready list in minutes.
How it works
Three steps between you and a clean list
01
Upload your list
Drag in a CSV or TXT file — or import directly from HubSpot, ActiveCampaign, Mailgun, and other integrations. No software to install.
02
Twelve checks run on every address
Syntax, MX records, SMTP handshakes, spam traps, disposable domains, duplicates, role accounts, complainers, risky TLDs — the full toolbox, every time.
03
Download what you need
Results are segmented into six categories. Export only the Deliverable segment — or any combination — and hit send with confidence.
What you can expect
Accuracy that's never taken for granted
Adopting our list cleaning service means every address you target has been meticulously inspected — Gmail, Outlook, Yahoo, AOL, and every domain in between.
Quality assurance
99%+ accuracy on every list. In other words: any email tagged 'Deliverable' is one you can safely send to — and we back that with a full money-back guarantee.
Bad email removal
ELV removes 99.9% of spam traps, hard bounces, and toxic addresses — the emails that quietly poison your sender reputation.
Performance
Expect 99.99% uptime and verification speeds over 100,000 emails per hour. Greylisted addresses get an automatic second pass instead of a wrong answer.
Segmented results
Six intuitive result codes — download only what you need
No wading through raw logs. Every address lands in one of six clear categories, and each segment downloads separately. Most senders export Deliverable and move on.
The address exists and accepts mail. Safe to send.
The address doesn't exist or can't receive mail. Remove it.
A temporary, throwaway address. It will bounce soon.
The server accepts everything; deliverability is uncertain.
The server didn't respond conclusively. Retry or exclude.
A trap address used to catch spammers. Never send to it.
Included with every clean
The full 12-tool verification toolbox
Duplicate removal
Detects and removes every duplicate email in your records, so you never pay to verify — or send to — the same address twice.
Spam trap removal
Flags and removes addresses that match known spam trap patterns before they can poison your sender reputation.
Risk validator
Scans for high-risk keywords and shady top-level domains that correlate with abuse, complaints, and blocklistings.
MTA / MX validation
Checks that each domain's Mail Transfer Agent has a valid MX record and can actually accept mail.
Domain validation
Removes every address on a dead, parked, or invalid domain — emails that can never be delivered.
Complainer database
Eliminates addresses matching our proprietary database of known complainers — the people who mark legitimate mail as spam.
Syntax verifier
Catches malformed addresses that violate RFC syntax standards and removes them instantly.
Real-time SMTP check
Performs a live, untraceable SMTP handshake against addresses that can't be validated by any other method.
Team accounts
Invite your whole team to collaborate in one workspace while sharing a single pool of credits — no per-seat fees.
Role email checker
Identifies role-based and free accounts (info@, admin@, sales@) commonly used to mask real email addresses.
Anti-greylisting tech
When a server greylists our check, we automatically wait and retry — so temporary deferrals never get misclassified.
Selectable downloads
Download exactly the segments you need — deliverable only, risky only, or any combination of result categories.
