Free DMARC checker

See whether your domain has a DMARC record, and whether Outlook, Hotmail and MSN will accept your email.

The part after the @ in your email address.

What is DMARC?

DMARC is a short line of text you add to your domain’s settings. When an email arrives claiming to be from you, the receiving mail server checks that it really is. DMARC tells that server what to do with email that fails: deliver it anyway, send it to spam, or refuse it. It can also send you reports on who is sending email in your name.

Why does Microsoft care?

Microsoft requires DMARC for email sent to Outlook.com, Hotmail, Live and MSN addresses, and rejects email that fails its checks. Lots of your customers use these addresses, so a missing record can stop your emails reaching them.

What can I do about this?

Type your domain into the box above to see whether it needs fixing. If it does, contact whoever manages your domain (often your web designer or the company you bought the domain from) and ask them to add a DMARC record. If you’re a Buzzshot customer and your domain needs fixing, we’ll have already been in touch. Go to Settings → Emails → Verify Domain for step-by-step instructions, or email support@buzzshot.com and we’ll help.
