About Mailidator Email Validator
Mailidator Email Validator adds a tiny check button next to every email address on any webpage. One click reveals a detailed validation report — right on the page, without switching tabs.
─────────────────────────────────────
WHAT GETS CHECKED
─────────────────────────────────────
✓ MX Record — Does the domain actually accept email?
✓ Disposable / Temporary — Is this a throwaway inbox from Mailinator, Guerrilla Mail, 10 Minute Mail, and 1,000+ others?
✓ Forwarding Service — Is the address routed through an email forwarding proxy?
✓ Role Account — Is this a generic address like info@, support@, noreply@?
✓ Free Provider — Gmail, Yahoo, Outlook, or a business domain?
✓ Overall Verdict — VALID, INVALID, DISPOSABLE, FORWARDING, or RISKY — color-coded for instant recognition.

WHO IT'S FOR
─────────────────────────────────────
→ DEVELOPERS & QA ENGINEERS
Quickly inspect email fields in staging environments, test fixtures, and admin panels. No API call needed from the console — just click the button next to any address.
→ COMMUNITY MODERATORS & TRUST & SAFETY TEAMS
Spot throwaway accounts before they post spam or abuse. The disposable and forwarding checks flag the most common evasion tactics in seconds.
→ CRM & SALES TEAMS
Keep your contact lists clean. Before you import or email a lead, confirm the address has a valid MX record and isn't a role alias that nobody reads.
→ CUSTOMER SUPPORT AGENTS
Verify a customer's email address is real while you're looking at their account — without leaving the support dashboard.
→ GROWTH & MARKETING TEAMS
Reduce bounce rates by checking email quality directly in your ESP, spreadsheet, or CRM — wherever the address appears on screen.

HOW IT WORKS
─────────────────────────────────────
1. Install the extension and connect your free Mailidator account.
2. Browse to any page containing email addresses.
3. A small icon appears next to each address.
4. Click the icon — a tooltip appears with the full validation result.
5. Badges show you exactly which checks passed or failed.
The validation is powered by the Mailidator API, which cross-references live DNS lookups, a regularly updated disposable domain database, and forwarding-service detection heuristics.
─────────────────────────────────────
PRIVACY & DATA
─────────────────────────────────────
• The extension only sends an email address to the Mailidator API when YOU click the validate button — never automatically.
• No browsing history, page content, or personal data is ever collected.
• Email addresses are used solely to perform the validation request and are not stored or sold.
• Full privacy policy: https://mailidator.com/privacy
