Every email list decays. But paying "API Taxes" of $0.008 per email to clean them is a rip-off. Invalid addresses cause bounces that damage your sender reputation and land your emails in the spam folder.
Cleanmails is a lightweight, self-hosted script designed to give you full control. We eliminate risky and undeliverable emails in two powerful phases—improving your deliverability and protecting your inbox placement.
Phase 1: Basic Cleaning works entirely on your local environment to filter out obvious junk. For 100% assured results, Phase 2 (SMTP Validation) performs a deep-level handshake to confirm the inbox truly exists.
🛡️ The 2-Phase Validation Process
Cleanmails verifies every email through a rigorous multi-layered scan split into two distinct operational phases:
Basic Cleaning (Works Offline)
1. Mistake & Typo Filter
Instantly catches typos like "gmal.com" or "yhaoo.com". We ensure every email structure is perfect.
2. Static Domain Check
Cross-references against our internal database of 123k+ disposable domains and 4k+ free providers.
3. "Burner" Email Detection
Identifies temporary/disposable providers used for fraud or "one-time" signups.
4. Risky Role Filtering
Flags support@, info@, or admin@ to help you target actual decision-makers.
SMTP Validation (100% Assured)
5. MX & DNS Intelligence
Real-time lookup of mail exchange records to verify if a domain can actually receive mail.
6. Real-time Handshake
Connects directly to the recipient's mail server to verify the inbox exists without sending an email.
7. Bot & Robot Analyzer
Advanced signal verification to distinguish machine-generated addresses from real humans.
8. RFC Compliance
100% compliance with RFC 5322 standards for industry-standard validation accuracy.

FAQ
Is this as accurate as paid APIs?
Yes. We use the same industry-standard signal checks (Syntax, DNS, MX Record deep-scans) that high-priced services use. The only difference is that you run the script yourself instead of paying them a markup.
Can I use this on lists of 100k+?
Absolutely. There are no artificial limits. You can process lists of any size. For extremely large lists, running locally on a powerful machine is recommended for maximum speed.
I'm not "technical"—can I use this?
Yes! We provide single-click deployment options and if you prefer a hands-off approach, we offer a Managed Setup service where our experts handle everything for you. You don't need to write a single line of code to get a powerful email cleaner live.
What do I get after purchasing?
You get instant automated access to our private GitHub repository containing the full source code, lifetime updates, and documentation. Everything you need to start cleaning today.
