DMARC authenticates emails and sender identity and proves that messages originate from a legitimate source authorized by your domain.<\/p>\n\n<p class=\"wp-block-paragraph\">This helps combat a growing threat \u2013 email spoofing. In email spoofing, attackers use a forged sender address to impersonate trusted entities, tricking recipients into clicking malicious links or revealing sensitive information. Here are the basic components of DMARC:<\/p>\n\n<ul class=\"wp-block-list\">\n<li><b>Authentication:<\/b> DMARC relies on existing email authentication protocols like <a href=\"https:\/\/www.mailgun.com\/blog\/deliverability\/spf-records-basics\/\" target=\"_tabs\" rel=\"noopener noreferrer\">SPF (Sender Policy Framework)<\/a> and <a href=\"https:\/\/www.mailgun.com\/pt\/blog\/deliverability\/entender-dkim-como-funciona\/\" target=\"_tabs\" rel=\"noopener noreferrer\">DKIM (DomainKeys Identified Mail)<\/a> to verify the legitimacy of incoming emails claiming to be from your domain.<\/li>\n\n\n\n<li><b>Reporting:<\/b> DMARC instructs email providers (like Gmail or Yahoo Mail) on how to handle emails that fail authentication checks. This allows you to receive reports on potential spoofing attempts and track unauthorized use of your domain.<\/li>\n\n\n\n<li><strong>Conformance:<\/strong>\u00a0DMARC lets you define your preferred action for unauthenticated emails: &#8220;reject,&#8221; &#8220;quarantine,&#8221; or &#8220;none (report only).&#8221; This allows you to take control of your email reputation and protect your users from phishing attacks, as Kate Nowrouzi points out in this video.<\/li>\n<\/ul>\n\t<div class=\"custom-video\">\r\n\t\t\t\t\t                    <div class=\"iframe-responsive-container lazy-video rounded-lg overflow-hidden \">\r\n                <a href=\"https:\/\/www.youtube.com\/watch?v=d_Gju38buII\" class=\"lazy-video-link\" data-lazy-video=\"d_Gju38buII\" target=\"_blank\" rel=\"nofollow\" role=\"button\" data-source=\"youtube\" data-language=\"pt\" data-thumb=\"https:\/\/img.youtube.com\/vi\/d_Gju38buII\/maxresdefault.jpg\" title=\"Sinch Video\">\r\n                    <div class=\"btn btn-light btn-light-social btn-play btn-play-circle\">\r\n                                                    <svg aria-hidden=\"true\" data-url=\"https:\/\/www.mailgun.com\/wp-content\/plugins\/sinch-core\/assets\/icons\/sinch\/play.svg\"><\/svg>\r\n                                            <\/div>\r\n                    <img decoding=\"async\"  src=\"https:\/\/img.youtube.com\/vi\/d_Gju38buII\/maxresdefault.jpg\" alt=\"Why DMARC is now mandatory for bulk email senders (and why your mom needs it)\">\r\n                <\/a>\r\n            <\/div>\r\n                        <script type=\"application\/ld+json\">\r\n            {\n    \"@context\": \"http:\/\/schema.org\",\n    \"@type\": \"VideoObject\",\n    \"@id\": \"https:\/\/www.youtube.com\/watch?v=d_Gju38buII#VideoObject\",\n    \"thumbnailUrl\": \"https:\/\/img.youtube.com\/vi\/d_Gju38buII\/maxresdefault.jpg\",\n    \"embedUrl\": \"https:\/\/www.youtube.com\/embed\/d_Gju38buII\",\n    \"contentUrl\": \"https:\/\/www.youtube.com\/watch?v=d_Gju38buII\",\n    \"name\": \"Why DMARC is now mandatory for bulk email senders (and why your mom needs it)\",\n    \"description\": \"Email authentication requirements are more than just technical hurdles \\u2013 they're essential steps toward creating a more secure email ecosystem. In this video, Kate Nowrouzi explains why Yahoo and Gmail have a new sender requirement that makes the DMARC specification a mandatory part of email authentication. If you are bulk sender, and you want to reach Yahoo and Gmail users, you better be sure that DMARC is implemented. Here\\u2019s why... \\n\\nDMARC (Domain-based Message Authentication, Reporting and Conformance) is the best defense the email industry has against phishing and brand spoofing in the inbox. Scammers have gotten very good at designing emails that look and read as if they came from trusted brands. Kate describes exactly how someone\\u2019s mother could easily be confused by email spoofing. But the truth is, even the savviest subscribers fall prey to these sophisticated scams. When enforced, DMARC can help prevent malicious emails from ever getting delivered. \\n\\nWatch now to find out more about why DMARC makes the email inbox a safer place, building trust between email senders, recipients, and mailbox providers. \\n\\nExplore the \\u201cState of email deliverability 2025\\u201d for more on the new requirements: \\nhttps:\/\/www.mailgun.com\/resources\/research\/yahoogle-bulk-senders\/  \\n\\nGet further insights from industry experts on the importance of DMARC: \\nhttps:\/\/www.mailgun.com\/blog\/deliverability\/dmarc-insights-from-dmarcian\/\",\n    \"uploadDate\": \"2024-11-20T16:54:11+00:00\",\n    \"duration\": \"PT1M8S\"\n}        <\/script>\r\n        \t\t\r\n\t\t\t<\/div>\r\n\r\n\t\r\n\n<h3 class=\"wp-block-heading\">DMARC policies<\/h3>\n\n<p class=\"wp-block-paragraph\">DMARC builds on the authentication capabilities of SPF and DKIM, but goes further and allows senders to tell receiving servers how they want messages that fail authentication to be managed. This is done through selecting policies and there are three possible options.<\/p>\n\n<h4 class=\"wp-block-heading\">None<\/h4>\n\n<p class=\"wp-block-paragraph\">The <b>p=none <\/b>tag makes no changes to your existing arrangement \u2013 the inbox provider will pass on the message as normal to the recipient.<\/p>\n\n<h4 class=\"wp-block-heading\">Quarantine<\/h4>\n\n<p class=\"wp-block-paragraph\">The <b>p=quarantine<\/b> tag means sending unqualified mail to the spam folder until you are 100% sure where these emails are originating.<\/p>\n\n<h4 class=\"wp-block-heading\">Reject<\/h4>\n\n<p class=\"wp-block-paragraph\"><b>p=reject<\/b> is the end goal of DMARC adoption, and <a href=\"https:\/\/www.mailgun.com\/pt\/blog\/email\/previsoes-de-e-mail-2024\/\" target=\"_tabs\" rel=\"noopener noreferrer\">according to our deliverability experts<\/a>, it\u2019s where the future of the sender requirements is headed.

And this is where the first wave of confusion and questions came in from senders. Will I be impacted?

It sounds like an intense line of witness questioning \u2013 and many senders probably resonate with that feeling of being in the hotseat when it comes to these requirements. So, here\u2019s deal, <b>Google defines bulk senders as those who send 5,000 emails within a 24-hour window.<\/b> Seems straightforward enough.<\/p>\n\n<p class=\"wp-block-paragraph\">Yahoo&#8217;s definition, however, is intentionally numberless.

If DMARC is so great at validating sender identity and protecting user\u2019s inboxes, why haven\u2019t senders more widely adopted it? The answer is twofold. It\u2019s both more expensive to implement than authentications like SPF and DMARC, and more technically demanding with different challenges depending on the size of your organization. Here are some of the big challenges:<\/p>\n\n<ul class=\"wp-block-list\">\n<li><b>Shadow IT:<\/b> In complex IT environments, identifying all sources of email within the organization can be challenging. Shadow IT, where departments use unauthorized email services outside the central IT purview, can make DMARC implementation difficult. <b>To overcome this, do a comprehensive audit of all your email sending sources before rolling out DMARC policies.<\/b><\/li>\n<\/ul>\n    <div data-content-type=\"longform\" class=\"quote hub-quote longform-spacings d-flex flex-column rounded-lg px-5 py-6 px-md-6 py-md-7 p-lg-7 shadow-sm bg-primary\" data-theme=\"light\">\r\n\r\n        <div class=\"quote-logo mb-3\">\r\n                            <svg height=\"40\" class=\"quote-icon quote-icon-color\" aria-hidden=\"true\" data-url=\"https:\/\/www.mailgun.com\/wp-content\/plugins\/sinch-core\/assets\/icons\/custom-icons\/quotes-right.svg\"><\/svg>\r\n                    <\/div>\r\n\r\n        <blockquote class=\"quote-content content-body m-0 text-body-color\" id=\"quote-block-b9361ea39cfcb51a1f116d16580188dd\">\r\n            &#8220;For enterprises the challenging Is mostly shadow IT, and by that, I mean business units within the organization have individual needs for services. So, they go out and purchase systems for things like benefits management that sends reports every month. And the service does that by essentially spoofing the organizations domain \u2013 in a legitimate way \u2013 but that type of mail source can make it harder to achieve DMARC alignment.&#8221;        <\/blockquote>\r\n\r\n                    <div class=\"d-flex gap-3 mt-5\">\r\n                                    <div>\r\n                        <img decoding=\"async\" width=\"72\" height=\"72\" class=\"rounded-lg quote-author\" src=\"https:\/\/www.mailgun.com\/wp-content\/uploads\/2025\/07\/ash-morin_headshot.png\" alt=\"Foto de Ash Morin\">\r\n                    <\/div>\r\n                                <div class=\"d-flex flex-column align-self-center fs-sm\">\r\n                    <cite class=\"mb-0 fw-bold text-accent fst-normal\" aria-describedby=\"quote-block-b9361ea39cfcb51a1f116d16580188dd\">\r\n                        Ash Morin                    <\/cite>\r\n                                            <span class=\"mb-0 text-body-color\">Director of Deployment Services at dmarcian<\/span>\r\n                                    <\/div>\r\n            <\/div>\r\n            <\/div>\r\n\n<ul class=\"wp-block-list\">\n<li><b>Third-party dependencies:<\/b> Many organizations rely on third-party email service providers (ESPs) for marketing campaigns or transactional emails.

The first is to make sure you\u2019re sending with best practices like great <a href=\"https:\/\/www.mailgun.com\/pt\/blog\/deliverability\/como-gerenciar-sua-lista-de-e-mails\/\" target=\"_tabs\" rel=\"noopener noreferrer\">list hygiene<\/a> and <a href=\"https:\/\/www.mailgun.com\/pt\/blog\/email\/segmentacao-de-lista-de-e-mails\/\" target=\"_tabs\" rel=\"noopener noreferrer\">good segmentation<\/a>. These <a href=\"https:\/\/www.mailgun.com\/blog\/email\/understanding-email-deliverability\/\" target=\"_tabs\" rel=\"noopener noreferrer\">deliverability basics<\/a> will help keep your mail sources organized and optimized which makes it easier to manage DMARC.<\/p>\n\n<p class=\"wp-block-paragraph\">The second is to find strong resources so you can troubleshoot when you need to. Resources are going to be your best friend when it comes to navigating DMARC adoption. We\u2019ve linked some great information throughout this post, but you should also check out dmarcian.com and their <a href=\"https:\/\/dmarcian.com\/why-dmarc\/\" target=\"_tabs\" rel=\"noopener noreferrer\">sender resources tab<\/a>. They\u2019re the DMARC experts and have assembled everything you need to know.<\/p>\n\n<p class=\"wp-block-paragraph\">We\u2019ve been covering the <i>Yoogle<\/i> changes for a while now, and we\u2019ve got some great information about the requirements.
