Email DNS & Deliverability Checker


Email DNS records (SPF, DMARC, MX, DKIM) dictate who is authorized to send emails on behalf of your domain, where incoming emails are delivered, and how receiving mailboxes (like Gmail, Outlook, and Yahoo) handle fraudulent or spoofed emails.

Following the strict enforcement mandates introduced by Google and Yahoo, misconfigured or missing records can cause your genuine emails to land in spam folders or be rejected entirely. Enter any domain below for an in-depth, plain-English breakdown of your email deliverability, authorized sending platforms, anti-spoofing policy, and security health score.
