First, confirm that you do have a published DMARC TXT record at dmarc.yourdomain.com. Use a <a href=\"https:\/\/threatcop.com\/dmarc-record-checker\">DMARC checker tool<\/a> to verify. Your published DMARC TXT record should look good, begin with <kbd>v=DMARC1<\/kbd>; and then contain a policy tag, such as <kbd>p=none<\/kbd>;.<\/span><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"font-weight: 400; color: #000000;\">You can only publish one DMARC record per domain.
