Delivery refers to whether a message is accepted by the receiving mail server, while deliverability measures where that message lands in the inbox.<\/p>\n\n<p class=\"wp-block-paragraph\"><b>What is email delivery?<\/b><\/p>\n\n<ul class=\"wp-block-list\">\n<li><strong>Delivery<\/strong> refers to whether a mail server accepts your message. A high delivery rate may still not indicate inbox placement. An email can be counted as \u00ab\u00a0delivered\u00a0\u00bb even if it lands in spam.<\/li>\n<\/ul>\n\n<p class=\"wp-block-paragraph\"><b>What is email deliverability?<\/b><\/p>\n\n<ul class=\"wp-block-list\">\n<li><a href=\"https:\/\/www.mailgun.com\/blog\/email\/understanding-email-deliverability\/\">Deliverability<\/a> focuses on inbox placement and engagement.

It verifies that your messages are legitimate and not spoofed, which helps protect both your brand and recipients from phishing attacks. In 2025, authentication will be critical for inbox placement, especially with new requirements from Gmail and Yahoo.<\/p>\n\n<h3 class=\"wp-block-heading\">The three top authentication protocols:<\/h3>\n\n<ul class=\"wp-block-list\">\n<li><a href=\"https:\/\/www.mailgun.com\/blog\/deliverability\/spf-records-basics\/\"><strong>SPF (Sender Policy Framework):<\/strong><\/a>\u00a0Defines which servers can send on your domain\u2019s behalf.<\/li>\n\n\n\n<li><a href=\"https:\/\/www.mailgun.com\/fr\/blog\/deliverability\/comprendre-dkim-fonctionnement\/\"><strong>DKIM (DomainKeys Identified Mail):<\/strong><\/a>\u00a0Adds an encrypted signature to verify your email&rsquo;s origin.<\/li>\n\n\n\n<li><a href=\"https:\/\/www.mailgun.com\/fr\/blog\/deliverability\/implementer-dmarc\/\"><strong>DMARC (Domain-based Message Authentication, Reporting &amp; Conformance):<\/strong><\/a>\u00a0Directs providers on handling failed authentication and generates reports for senders.<\/li>\n<\/ul>\n\n<p class=\"wp-block-paragraph\">DMARC is an email authentication protocol designed to give email domain owners the ability to protect their domain from unauthorized use, commonly known as email spoofing. It works by works by using DNS records to specify how an email from a domain should be handled if it fails authentication checks through SPF and DKIM. <\/p>\n\n<p class=\"wp-block-paragraph\">DMARC was a big topic in email this year and for good reason. While the new sender requirements currently only mandate a DMARC policy of p=none (which is a monitor only policy), that will likely change. And it should.<\/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-63ad42d23fd97c64b73467c02514f826\">\r\n            The p=reject policy is the most effective policy.

However, this doesn\u2019t guarantee that the email reaches the inbox. Deliverability focuses on where the email lands (inbox vs. spam) and whether users engage with it.<\/p>\n\n<h4 class=\"wp-block-heading\">How can I prevent my emails from landing in the spam folder?<\/h4>\n\n<p class=\"wp-block-paragraph\">Avoid common spam triggers by maintaining good list hygiene, minimizing complaints, and following email best practices. Ensure your content is relevant and your list is free from spam traps or inactive addresses.<\/p>\n\n<h4 class=\"wp-block-heading\">Why is email authentication important for deliverability?<\/h4>\n\n<p class=\"wp-block-paragraph\">Authentication protocols like SPF, DKIM, and DMARC verify your sender identity, preventing phishing and ensuring that mailbox providers trust your emails. Without proper authentication, your messages may be flagged as spam or blocked altogether.<\/p>\n\n<h4 class=\"wp-block-heading\">How can I secure my email sending infrastructure?<\/h4>\n\n<p class=\"wp-block-paragraph\">Use double opt-in for subscribers, provide easy unsubscribe options, enable two-factor authentication (2FA), and perform regular audits of your sending accounts. Separating transactional and marketing emails on different subdomains or IPs can also prevent issues from affecting all your mail streams.<\/p>\n\n<h4 class=\"wp-block-heading\">How do I continuously improve my email performance and deliverability?<\/h4>\n\n<p class=\"wp-block-paragraph\">Regularly monitor engagement metrics like opens, clicks, and spam complaints. Use tools like <a href=\"https:\/\/www.mailgun.com\/fr\/blog\/product\/integration-avec-google-postmaster-tools\/\" target=\"_tabs\" rel=\"noopener noreferrer\">Google Postmaster and Microsoft SNDS<\/a> to track your sender reputation. This will set you apart already, we reported that 70% of senders who took our survey aren\u2019t using these tools. <\/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=cB49YAEPOPI\" class=\"lazy-video-link\" data-lazy-video=\"cB49YAEPOPI\" target=\"_blank\" rel=\"nofollow\" role=\"button\" data-source=\"youtube\" data-language=\"fr\" data-thumb=\"https:\/\/img.youtube.com\/vi\/cB49YAEPOPI\/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\/cB49YAEPOPI\/maxresdefault.jpg\" alt=\"Optimizing your email strategy for 2025\">\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=cB49YAEPOPI#VideoObject\",\n    \"thumbnailUrl\": \"https:\/\/img.youtube.com\/vi\/cB49YAEPOPI\/maxresdefault.jpg\",\n    \"embedUrl\": \"https:\/\/www.youtube.com\/embed\/cB49YAEPOPI\",\n    \"contentUrl\": \"https:\/\/www.youtube.com\/watch?v=cB49YAEPOPI\",\n    \"name\": \"Optimizing your email strategy for 2025\",\n    \"description\": \"Whether this was your best year yet, or you still need some work, Mailgun is looking back into the top 2024 email trends and practices to provide insight into how to win in 2025, based on our new State of Deliverability Report.  \\n\\nJoin Mailgun\\u2019s Nick Schafer, Senior Manager of Deliverability and Compliance, and Kate Nowrouzi, VP of Deliverability and industry evangelists, as we look through some of the most impactful 2024 sending data and share unique insights that will help you reach more inboxes this year.  \\n\\n\\nWhat we will cover: \\n\\n-Understanding delivery vs deliverability and why they both matter \\n\\n-Top 5 reasons you are landing in the spam folder instead of the inbox  \\n\\n-Security best practices to protect your brand and your customers  \\n\\n-The most important email metrics to track in 2025 and how to track them\",\n    \"uploadDate\": \"2025-02-05T18:55:47+00:00\",\n    \"duration\": \"PT1H40S\"\n}        <\/script>\r\n        \t\t\r\n\t\t\t<\/div>\r\n\r\n\t\r\n\r\n    <aside data-content-type=\"longform\"  class=\"banner-block longform-spacings rounded-lg shadow-lg px-5 py-6 px-md-6 py-md-7 p-lg-7 bg-light\" data-theme=\"dark\" aria-labelledby=\"banner-block-block_64e036b53011fbccbc7a8162748a7518\">\r\n                    <p class=\"text-uppercase section-caption text-body-color\">\r\n                Sign Up            <\/p>\r\n                            <p class=\"h4 text-accent fw-bold\" id=\"banner-block-block_64e036b53011fbccbc7a8162748a7518\">\r\n                It&rsquo;s easy to get started.
