InboxGreen DNS Checker

Check SPF, DKIM, and DMARC records for any domain instantly.

Check your email DNS records in seconds -- right from your browser toolbar. Click the InboxGreen icon on any website to instantly check whether that domain's SPF, DKIM, and DMARC records are configured correctly. Or right-click any link to check that domain without leaving the page. What it checks: - SPF: Is the domain authorized to send email? - DKIM: Are outgoing emails cryptographically signed? - DMARC: Is the domain protected against spoofing? Unlike other SPF and DMARC checkers, InboxGreen detects when DMARC is set to p=none -- a hidden risk that looks like a pass but leaves your domain completely unprotected against spoofing. Each record shows Pass, At Risk, or Missing. If something needs fixing, a direct link takes you to InboxGreen.email for a full diagnostic report. Who uses this: - Developers checking DNS config before launch - Marketers diagnosing email deliverability problems - IT admins auditing client domains without opening a terminal Free. No signup. Works on any domain.
