These three protocols authenticate who you are and protect against spoofing, phishing, and impersonation. In short, they prove you&#8217;re not a bad actor, or at least that you\u2019re not acting badly in email.<\/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\"> Learn more about the basics of email deliverability from our first episode of Deliverability Academy, <a href=\"https:\/\/www.mailgun.com\/de\/blog\/deliverability\/deliverability-academy-folge-eins-zusammenfassung\/\">check out the recap.<\/a><\/div>\r\n    <\/div>\r\n\n<p class=\"wp-block-paragraph\">Even though these authentication protocols have been par for the course for ages, DMARC was much less adopted given that senders have to jump through a couple more hoops to get it. When <a href=\"https:\/\/www.mailgun.com\/de\/blog\/deliverability\/gmail-und-yahoo-mailbox-neuerungen-2024\/\" target=\"_tabs\" rel=\"noopener noreferrer\">Gmail and Yahoo<\/a> released their sender requirements in 2023, <a href=\"https:\/\/www.mailgun.com\/de\/blog\/email\/end-zusammenfassung-staffel-sechs-folge-1-dmarc\/\" target=\"_tabs\" rel=\"noopener noreferrer\">DMARC stopped being optional.<\/a> And now, Microsoft has hopped on the same train.<\/p>\n\n<p class=\"wp-block-paragraph\">DMARC finally closes the loop that SPF and DKIM leave open. It checks whether the domain in your visible From address actually aligns with your authenticated domain. That alignment is what mailbox providers care about most now.<\/p>\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-27c5b1b8d997ac386c59538e08314140\">\r\n            &#8222;DMARC actually fills in a gap that SPF and DKIM both kind of left behind\u2026 it closes that loophole and makes sure that you are who you say you are.\u201d         <\/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\/Alison-Gootee_Headshot.jpg\" alt=\"Foto von Alison Gootee\">\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-27c5b1b8d997ac386c59538e08314140\">\r\n                        Alison Gootee                    <\/cite>\r\n                                            <span class=\"mb-0 text-body-color\">Deliverability Advocacy Specialist Sinch Mailgun<\/span>\r\n                                    <\/div>\r\n            <\/div>\r\n            <\/div>\r\n\n<p class=\"wp-block-paragraph\">And while <code>p=none<\/code> might be acceptable today, it\u2019s a placeholder at best.

Without reporting, a DMARC record isn\u2019t doing much. Reports are the \u201cR\u201d in DMARC and they provide crucial visibility into your domain\u2019s email ecosystem. From unknown senders within your own organization to external threats, these reports shine a light on what\u2019s really happening with your email.<\/div>\r\n    <\/div>\r\n\n<h2 class=\"wp-block-heading\">Microsoft expands the playbook<\/h2>\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/www.mailgun.com\/de\/blog\/deliverability\/microsoft-absender-anforderungen\/\" target=\"_tabs\" rel=\"noopener noreferrer\">When Microsoft came to the table<\/a> they didn\u2019t do it with quite the same gusto as Yahoogle. Instead of a strict list of thresholds and percentages they came with a list of recommendations, but they still do require DMARC like the other big inbox providers.<\/p>\n\n<p class=\"wp-block-paragraph\">Their guidance includes expected hits like unsubscribe headers<a href=\"https:\/\/www.mailgun.com\/de\/blog\/deliverability\/bedeutung-der-e-mail-listenbereinigung\/\" target=\"_tabs\" rel=\"noopener noreferrer\">, list hygiene<\/a>, and reply handling, but they aren\u2019t as strict. Instead of requiring a one-click unsubscribe with <a href=\"https:\/\/www.mailgun.com\/de\/blog\/deliverability\/what-is-rfc-8058\/\" target=\"_tabs\" rel=\"noopener noreferrer\">RFC 8058<\/a> for example, Microsoft is just requiring a clear, functional unsubscribe process.<\/p>\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-c6afaee4d5ac513d5918fe2152e8563e\">\r\n            &#8222;Merely meeting the authentication standard is not the thing that\u2019s going to guarantee inbox placement\u2014it\u2019s just a bare minimum.\u201d         <\/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\/Alison-Gootee_Headshot.jpg\" alt=\"Foto von Alison Gootee\">\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-c6afaee4d5ac513d5918fe2152e8563e\">\r\n                        Alison Gootee                    <\/cite>\r\n                                            <span class=\"mb-0 text-body-color\">Deliverability Advocacy Specialist Sinch Mailgun<\/span>\r\n                                    <\/div>\r\n            <\/div>\r\n            <\/div>\r\n\n<p class=\"wp-block-paragraph\">So why is Microsoft seemingly less strict? The truth, we think, is in the subtext. And the subtext here says, \u201cYou can follow all the technical rules and still be unwelcome if your emails feel spammy or careless.\u201d Microsoft isn\u2019t just looking at your authentications; it\u2019s reading the room and has made it clear they will react based on how recipients manage your messages.<\/p>\n\n<h2 class=\"wp-block-heading\">Why respectful sending is no longer optional<\/h2>\n\n<p class=\"wp-block-paragraph\">One of our favorite parts of Deliverability Academy are the gold nuggets of wisdom that we get from our panel of experts and Natalie Hays never disappoints.<\/p>\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-44bd601c0f58bf14efda779f6d82404c\">\r\n            &#8222;Imagine you meet someone new, and you want to be friends.

That\u2019s how subscribers feel when they get email after email with no room to breathe. When the opt-out link is buried in a footer. When they can\u2019t tell why they\u2019re even on the list.<\/p>\n\n<p class=\"wp-block-paragraph\">Tools like easy unsubscribe and preference centers aren\u2019t a nice-to-have, they\u2019re a sanity check. Let people choose how often they want to hear from you. Let them opt down before they opt out and don\u2019t act surprised when high unsubscribe rates tank your sender reputation \u2013especially if you weren\u2019t really listening to your audience in the first place.<\/p>\n\n<h2 class=\"wp-block-heading\">Getting started with Mailgun DMARC<\/h2>\n\n<p class=\"wp-block-paragraph\">One of the big questions our audience had was what should you do if you\u2019re overwhelmed by DMARC reporting? If you&#8217;re staring at XML files and pretending they make sense, you\u2019re not alone.<\/p>\n\n<p class=\"wp-block-paragraph\">That\u2019s where solutions like <a href=\"https:\/\/www.mailgun.com\/de\/blog\/email\/end-zusammenfassung-staffel-sechs-folge-1-dmarc\/\" target=\"_tabs\" rel=\"noopener noreferrer\">Mailgun\u2019s DMARC monitoring, powered by Red Sift<\/a>, comes in. It simplifies DMARC deployment and makes the reports digestible. You\u2019ll know who\u2019s sending on your behalf, what\u2019s failing, and how to fix it.<\/p>\n\n<h2 class=\"wp-block-heading\">Wrapping Up<\/h2>\n\n<p class=\"wp-block-paragraph\">Of course, if your current solution is working and you\u2019re confident in your enforcement posture, the advice was simple: \u201cDon\u2019t rock the boat unless it\u2019s filling with water.\u201d Mailgun isn\u2019t the only solution to deliverability, but hey, we\u2019re here if you need us.<\/p>\n\n<p class=\"wp-block-paragraph\">Landing in the inbox isn\u2019t just a technical problem. It\u2019s a trust problem. Mailbox providers are looking at what you send, how you send it, and whether your subscribers even want it.<\/p>\n\n<p class=\"wp-block-paragraph\">SPF, DKIM, and DMARC are non-negotiable, but what really keeps you out of spam is being a good sender. That means giving subscribers control, making it easy to opt out, sending content people actually expect, and responding like there\u2019s a real person on the other end.<\/p>\n\n<p class=\"wp-block-paragraph\">Authentication and meeting requirements gets you through the door. Respect keeps you in the room.<\/p>\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=pc8UaW9hYt4\" class=\"lazy-video-link\" data-lazy-video=\"pc8UaW9hYt4\" target=\"_blank\" rel=\"nofollow\" role=\"button\" data-source=\"youtube\" data-language=\"de\" data-thumb=\"https:\/\/img.youtube.com\/vi\/pc8UaW9hYt4\/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\/pc8UaW9hYt4\/maxresdefault.jpg\" alt=\"Deliverability Academy: Authentication and Microsoft\u2019s Sender Requirements\">\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=pc8UaW9hYt4#VideoObject\",\n    \"thumbnailUrl\": \"https:\/\/img.youtube.com\/vi\/pc8UaW9hYt4\/maxresdefault.jpg\",\n    \"embedUrl\": \"https:\/\/www.youtube.com\/embed\/pc8UaW9hYt4\",\n    \"contentUrl\": \"https:\/\/www.youtube.com\/watch?v=pc8UaW9hYt4\",\n    \"name\": \"Deliverability Academy: Authentication and Microsoft\\u2019s Sender Requirements\",\n    \"description\": \"Join us as we walk through the Microsoft sender requirements and why authentication is so important for future-proofing your email program.  \\n\\n\\nWhat we\\u2019ll talk about:\\n\\n- How Microsoft\\u2019s updated sender rules impact bulk senders \\n\\n- What are authentication best practices in 2025 and beyond \\n\\n- Common mistakes that will keep you out of the inbox, even with authentication in place\\n\\nYou\\u2019ll learn: \\n\\n- The role of SPF, DKIM, and DMARC in complying with mailbox provider policies \\n\\n- How to proactively prevent deliverability issues with proper setup \\n\\n- Actionable steps to prepare your program for evolving sender requirements\",\n    \"uploadDate\": \"2025-06-18T19:11:34+00:00\",\n    \"duration\": \"PT59M13S\"\n}        <\/script>\r\n        \t\t\r\n\t\t\t<\/div>\r\n\r\n\t\r\n","protected":false},"excerpt":{"rendered":"<p>Die Anforderungen f\u00fcr den Posteingang sind strenger geworden.
