Bulk Email Verifier That Never Counts Credits
Upload a list, get a live SMTP verdict for every address: valid, invalid, catch-all or unknown. Unlimited verification on lifetime plans. Cleaning services charge this per list; you pay once.
How it works
List in, clean list out, three steps
1. Upload or import
Paste addresses, upload a CSV, or verify lists you scraped or pulled from the 420M+ database inside Getlead.
2. SMTP checks run
Every address gets a live handshake with its mail server: syntax, MX, mailbox existence and catch-all detection.
3. Export the clean list
Download or send directly from Getlead with invalids removed and catch-alls segmented.
Results
Every address gets one of four verdicts
Mailbox confirmed by the server. Safe to send.
Mailbox does not exist. Remove before sending.
Domain accepts everything. Cap at 20% of a campaign.
Server did not answer. Re-verify later.
vs cleaning services
Email list cleaning services charge per list. Forever.
Same SMTP checks, different business model. Credit pricing punishes you for re-verifying, which is exactly what good hygiene requires.
Public list-cleaning and credit prices, July 2026. Addresses decay a few percent monthly; re-verification is not optional.

FAQ
Bulk verification questions
How do I verify email addresses in bulk?
Upload your list (CSV or paste) to a bulk verifier that runs SMTP checks. Each address gets a live mailbox check and comes back labeled valid, invalid, catch-all or unknown. Remove invalids, cap catch-alls, then send.
Is there a free bulk email verifier?
Most tools charge per 1,000 checks. Getlead includes unlimited bulk SMTP verification in lifetime plans from $9.90 once. Single addresses are free to check, 10 per day, no signup, at the free email verifier.
How is this different from an email list cleaning service?
Cleaning services run the same checks as a managed one-off job at $5+ per thousand with turnaround time. Here you get the same result instantly, repeatably, with no per-list cost.
How accurate is bulk SMTP verification?
It is the most accurate method available: the actual mail server confirms each mailbox. Verified lists bounce at 0.51% in our data. Catch-all domains are flagged separately since no tool can confirm those.
