Mail Check

Email Spoofing Protection Check

Enter your company's domain or email address (for example info@example.com). We look up public DNS records only, and show whether SPF, DKIM and DMARC are set up so that others cannot send email pretending to be you.

Why it matters

  • Without SPF, DKIM and DMARC, anyone can send email that looks like it comes from your domain, to your customers and partners.
  • Since February 2024, Gmail and Yahoo require SPF or DKIM for all senders, and DMARC for bulk senders. Missing records make your own mail land in spam.
  • Settings need to include every service that sends mail for you: your mail provider, your website's contact form, newsletter tools and so on.

This is a quick check using common DKIM selector names; a key under another name may not be detected. The domain you enter is logged to improve the tool.
