The interwebz is still the preferred platform for business and social interactions, so of course, there\u2019s more incentive for bad actors to target users for their own financial gain. Let\u2019s look at the stupid easy ways bad actors can lure us into a trap, and how we can stop getting pwned by spammers.<\/p>\n\r\n    <nav data-content-type=\"longform\" class=\"toc-block longform-spacings px-5 py-6 px-md-6 px-lg-7 py-md-7 bg-light fs-sm rounded-lg\" aria-labelledby=\"toc-title-5202\"><p class=\"h5 m-0\" id=\"toc-title-5202\">\u00cdndice<\/p><div class=\"d-flex mt-3\"><div class=\"w-auto fw-bold text-accent d-flex me-2\">01<\/div><div class=\"d-flex flex-column\"><a class=\"fw-bold scrollme link-body-color text-accent\" href=\"#how-dmarc-protects-your-reputation\">How DMARC protects your reputation<\/a><\/div><\/div><div class=\"d-flex mt-3\"><div class=\"w-auto fw-bold text-accent d-flex me-2\">02<\/div><div class=\"d-flex flex-column\"><a class=\"fw-bold scrollme link-body-color text-accent\" href=\"#what-types-of-attacks-can-dmarc-help-block\">What types of attacks can DMARC help block?<\/a><a class=\"scrollme link-body-color\" href=\"#youve-been-spoofed\">You\u2019ve been spoofed<\/a><a class=\"scrollme link-body-color\" href=\"#youve-gone-deep-sea-phishing\">You\u2019ve gone deep sea \u2018phishing\u2019<\/a><\/div><\/div><div class=\"d-flex mt-3\"><div class=\"w-auto fw-bold text-accent d-flex me-2\">03<\/div><div class=\"d-flex flex-column\"><a class=\"fw-bold scrollme link-body-color text-accent\" href=\"#wrapping-up\">Wrapping up<\/a><\/div><\/div><\/nav>\n<h2 class=\"wp-block-heading\">How DMARC protects your reputation<\/h2>\n\n<p class=\"wp-block-paragraph\">DMARC is the lesser known authentication. If you\u2019re in the email game, then it\u2019s more likely that you\u2019ve embraced DKIM and SPF. Though it\u2019s very effective \u2013 <a href=\"https:\/\/godmarc.com\/blogs\/dmarc-and-email-statistics\/\" target=\"_tabs\" rel=\"noopener noreferrer\">having stopped more than 90 million phishing attacks in the first half of 2022<\/a> alone, DMARC is still not widely adopted. With over 90% of cyber attacks beginning with phishing (the very thing DMARC defends against), this is the security protocol you don\u2019t want to sleep on.<\/p>\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/www.mailgun.com\/es\/blog\/deliverability\/autenticacion-emails-documento-identidad-envios\/\" target=\"_tabs\" rel=\"noopener noreferrer\">DKIM and SPF<\/a> are great for indicating where messages should be coming from, though not v<b>many ISPs filter email using these authentications alone.\u00a0Both<\/b> DKIM and SPF provide the mechanics to filter out messages\u00a0that fail their checks, but most providers will still allow message to go through. This is because it\u2019s really hard to tell how many legitimate emails are being sent that don\u2019t authenticate \u2013 especially if the sender isn\u2019t getting any feedback. This is where DMARC comes in.<\/p>\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/www.mailgun.com\/es\/blog\/deliverability\/implementar-dmarc\/\" target=\"_tabs\" rel=\"noopener noreferrer\">DMARC (Domain-based Message Authentication, Reporting &amp; Conformance)<\/a> uses both the SPF and DKIM records together to better identify who sent the message. It can tell you if the sender had permissions to send and identify themselves as the domain in the \u201cFrom\u201d field of your email header.<\/p>\n\n<p class=\"wp-block-paragraph\">Sender Policy Framework (SPF) is controlled at the DNS level. It\u2019s where you can say which servers can send on your behalf, and lets you reference whether the originating IP matches the list on your DNS<b>.\u00a0A matching IP is how the recipient server knows the message is coming from an authorized sender of your domain<\/b>.<\/p>\n\n<p class=\"wp-block-paragraph\">DomainKeys Identified Mail (DKIM) signs your messages to signal that it has been sent from the\u00a0 server that created the message, and not from an imposter that intercepted the message and inserted something into the message body itself.<\/p>\n\n<p class=\"wp-block-paragraph\">To pass DMARC checks, SPF or DKIM must meet the requirements of both alignment and authentication. There must be alignment between the domain in the \u201cfrom\u201d address, and the domain identified in the return path or \u201cd=\u201d portion of the DKIM signature.<\/p>\n    <div data-content-type=\"longform\"  class=\"callout text-body-color px-5 py-6 px-md-6 px-lg-7 py-md-7 longform-spacings rounded-lg bg-light\" data-theme=\"light\">\r\n\r\n        <div class=\"content-body\"> <b>Adding DMARC as a protection to your domain will help reduce the possibility of a bad actor using your domain name to send emails<\/b> from a random location that you did not designate with SPF.<\/div>\r\n    <\/div>\r\n\n<p class=\"wp-block-paragraph\">If you\u2019re looking for more resources on DMARC, the\u00a0<a href=\"https:\/\/dmarc.org\/resources\/products-and-services\/\" target=\"_tabs\" rel=\"noopener noreferrer\">DMARC site<\/a>\u00a0provides suggestions for aggregation services that take that return data and display it for you in a nice way that humans can read. Because who doesn\u2019t like a solid feedback loop that helps to improve email deliverability?<\/p>\n\n<h2 class=\"wp-block-heading\">What types of attacks can DMARC help block?<\/h2>\n\n<p class=\"wp-block-paragraph\">We\u2019re big fans of DMARC both in terms of security and deliverability. It\u2019s one thing to talk about the logistics, but what are some examples of the risks that DMARC helps prevent?<\/p>\n\n<h3 class=\"wp-block-heading\">You\u2019ve been spoofed<\/h3>\n\n<p class=\"wp-block-paragraph\">One of the easiest ways for bad actors to infiltrate our lives is to use our trusting \u2013 and often lax \u2013 attitude towards established senders.\u00a0<a href=\"https:\/\/searchsecurity.techtarget.com\/definition\/email-spoofing\" target=\"_tabs\" rel=\"noopener noreferrer\">Email spoofing<\/a>\u00a0tests our trust and exploits it, using it against us to see if we\u2019ll take the bait if it looks like a message is coming from someone we know. You can be on the receiving end and not know the difference because bad actors will mimic email headers to look legitimate.<\/p>\n\n<p class=\"wp-block-paragraph\">More sophisticated spoofing attacks will often include company logos, be well written, and have links to websites that also look legitimate, making it really hard for a user to realize that they are being phished until it\u2019s too late. But if you take a closer look at the full details of your email header, you can catch the weird things like IP addresses that you didn\u2019t authorize to send on your behalf.\u00a0<b>It\u2019s all too easy to replicate an email header and put your domain reputation at risk.<\/b><\/p>\n    <div data-content-type=\"longform\"  class=\"callout text-body-color px-5 py-6 px-md-6 px-lg-7 py-md-7 longform-spacings rounded-lg bg-light\" data-theme=\"light\">\r\n\r\n        <div class=\"content-body\"> DMARC reduces spoofing attack by preventing spoofers from using fake \u201cFrom\u201d addresses. It catches imposter emails by invalidating them through robust authentication standards.

Your own domain users are left vulnerable to <a href=\"https:\/\/www.mailgun.com\/es\/blog\/deliverability\/caught-in-a-phishing-line-what-we-do-and-how-you-can-protect-yourself\/\" target=\"_tabs\" rel=\"noopener noreferrer\">phishing attacks<\/a> where bad actors will trick recipients with personalized messages. These messages can\u00a0<b>attempt to gain passwords, payment information, or confidential company information<\/b>\u00a0that you would not normally share. So, if you can\u2019t function without binge watching Futurama, and Netflix is threatening to cancel your account because of a problem with your billing information\u2026I\u2019d say<\/p>\n\n<ol class=\"wp-block-list\">\n<li>You\u2019re all of us, and<\/li>\n\n\n\n<li>You might not question the legitimacy of this email:<\/li>\n<\/ol>\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" class=\"wp-image-4417\" width=\"594\" height=\"730\" src=\"https:\/\/www.mailgun.com\/wp-content\/uploads\/2025\/07\/Netflix-Phishing-Email.png\" alt=\"Phishing email that appears to be from Netflix\" srcset=\"https:\/\/www.mailgun.com\/wp-content\/uploads\/2025\/07\/Netflix-Phishing-Email.png 594w, https:\/\/www.mailgun.com\/wp-content\/uploads\/2025\/07\/Netflix-Phishing-Email-244x300.png 244w\" sizes=\"(max-width: 594px) 100vw, 594px\" \/><\/figure>\n\n<p class=\"wp-block-paragraph\">And that\u2019s just the small stuff. These attacks are the Moby Dick of \u2018phising\u2019\u2013\u00a0 just a security disaster waiting to happen because <b>of\u00a0how far they reach and the size of their impact<\/b>.\u00a0They can hit your organization in the form of a message sent from a senior executive or a high-profile contact and are made to look like official correspondence. It\u2019s pretty much a message you would reasonably expect like a legal subpoena, customer complaint, or a message from the CEO. If you\u2019re being asked to provide confidential information or direct payment to an obscure source\u2026flag it immediately.<\/p>\n    <div data-content-type=\"longform\"  class=\"callout text-body-color px-5 py-6 px-md-6 px-lg-7 py-md-7 longform-spacings rounded-lg bg-light\" data-theme=\"light\">\r\n\r\n        <div class=\"content-body\"> <b>If your domain has no DMARC record, hackers can more easily spoof an email address that is attached to your domain name.<\/b> At Mailgun, when adding a domain to your account you are\u00a0required to add DKIM and SPF records\u00a0\u2013 both of which help to indicate where the domain is allowed to send email from. By enabling DMARC, you have the added benefit of selecting a return address for reports of your domains sending activity to email hosting providers.<\/div>\r\n    <\/div>\r\n\n<h2 class=\"wp-block-heading\">Wrapping up<\/h2>\n\n<p class=\"wp-block-paragraph\">DMARC is by no means a magic wand that will eliminate spoofing of your domain, but it can deter a spammer or phisher from using your domain name while trying to execute one of these attacks. And of course, it can also\u00a0<b>help protect your domain reputation<\/b>\u00a0by validating your identity and separating your sending actions from a spammer who is trying to mimic you.<\/p>\n\n<p class=\"wp-block-paragraph\">To protect your own users from spoofing attacks, remember that DMARC is part of the toolset that you will need , but user education is key..
