Live check
Everything you need
One plugin, the whole deliverability toolkit
From a single check to enterprise list hygiene — every feature runs privately on your own WordPress install.
Deliverability scoring
Every address gets a 0–100 score and a letter grade so you know exactly what is safe to send.
Bulk list cleaning
Upload a CSV and verify thousands of addresses in the background with a downloadable report.
Spam-trap protection
Disposable, role-based, and a graded 0–5 toxicity score with spam-trap detection keep risky contacts out of your lists.
Blacklist monitoring
Scheduled DNSBL scans watch your sending domain and IP across major blocklists.
Form integrations
Block bad emails at signup in Contact Form 7, WPForms, Elementor, Gravity, and WooCommerce.
Developer API
Rate-limited API keys let you verify programmatically from your CRM, Zapier, or custom apps.
Private & self-hosted
Your data never leaves your server. No third-party API, no per-check fees, full ownership.

Why it matters
Protect your reputation, save on every send
-
Higher inbox placement
Removing invalid addresses lowers your bounce rate and keeps you out of spam folders.
-
Stop wasting send budget
Most ESPs charge per contact. Clean lists mean you only pay for people who actually exist.
-
Avoid spam traps & blacklists
Trap detection and DNSBL monitoring protect the domain reputation you have worked to build.

Loved by senders
Built for marketers, agencies & developers
Our bounce rate dropped to almost nothing after we started cleaning lists here first.
Being fully self-hosted was the dealbreaker for us — no contact data leaves our server.
The scoring grades make it trivial to decide which contacts are safe to email.
Questions
Frequently asked
Is my data sent to a third party?
No. Everything runs on your own WordPress server. There is no external verification API and no per-check fee.

We layer syntax, MX, live SMTP, disposable, role, and trap checks to produce a confidence score and clear grade for every address.
Can I verify large lists?
Yes. Upload a CSV and the bulk processor verifies addresses in the background, then gives you a downloadable report.
