Like a radio, deliverability relies on external factors to transmit messages. Where radios battle signal strength and interference, deliverability battles protocols and spam filters. The question is, do you know how to get your message out?<\/p>\n\n<p class=\"wp-block-paragraph\">In 2025 Mailgun conducted its annual <a href=\"https:\/\/www.mailgun.com\/fr\/state-of-email-deliverability\/chapter\/introduction\/\" target=\"_tabs\" rel=\"noopener noreferrer\">state of email deliverability report<\/a> and asked senders their view on email deliverability and their grasp on what email deliverability means.<\/p>\n\n<p class=\"wp-block-paragraph\">Out of the 1,100 people who took our survey, only about 5% described their job role as \u201cDeliverability Specialist.\u201d The truth is, there aren\u2019t too many deliverability specialists roaming across the email landscape, even though we need them. So, if you\u2019re like 95% of senders, read on to understand why you need high-quality deliverability expertise to support your email program.<\/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-5143\"><p class=\"h5 m-0\" id=\"toc-title-5143\">Table des mati\u00e8res<\/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=\"#understanding-the-impact-of-deliverability\">Understanding the impact of deliverability<\/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=\"#the-challenges-of-email-deliverability\">The challenges of email deliverability<\/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=\"#navigating-the-ins-and-outs-of-email-deliverability\">Navigating the ins and outs of email deliverability<\/a><a class=\"scrollme link-body-color\" href=\"#build-a-culture-of-continuous-deliverability-education\">Build a culture of continuous deliverability education<\/a><a class=\"scrollme link-body-color\" href=\"#partner-with-deliverability-experts\">Partner with deliverability experts<\/a><\/div><\/div><div class=\"d-flex mt-3\"><div class=\"w-auto fw-bold text-accent d-flex me-2\">04<\/div><div class=\"d-flex flex-column\"><a class=\"fw-bold scrollme link-body-color text-accent\" href=\"#troubleshooting-deliverability-issues-with-a-deliverability-expert\">Troubleshooting deliverability issues with a deliverability expert<\/a><\/div><\/div><\/nav>\n<h2 class=\"wp-block-heading\">Understanding the impact of deliverability<\/h2>\n\n<p class=\"wp-block-paragraph\"><b>Email deliverability is just the act of getting your message into your recipient&rsquo;s inbox.<\/b> That\u2019s it.<\/p>\n\n<p class=\"wp-block-paragraph\">What makes this seemingly simple act complicated are the differences between protocols and standards among mailbox providers, the filters set up to weed out spammers, and the increasing need for sender identity authentication.<\/p>\n\n<p class=\"wp-block-paragraph\">But why is email deliverability so important? Well, if emails don\u2019t land in the recipients&rsquo; inbox and are not read&#8230;what\u2019s the point of sending them?<\/p>\n\n<p class=\"wp-block-paragraph\">According to survey respondents, the biggest benefits of prioritizing email deliverability are improved customer satisfaction and increased email ROI. Makes sense \u2013 after all, that is <i>why<\/i> we send messages in the first place. The goal of email communication is to market a service, convey a story, or transmit something that impacts consumers while also benefiting the business.<\/p>\n\n<p class=\"wp-block-paragraph\">When it comes to numbers, email\u2019s ROI is already high, but when you partner with an ESP it increases further. In <a href=\"https:\/\/www.mailgun.com\/fr\/blog\/product\/etude-tei-forrester\/\" target=\"_tabs\" rel=\"noopener noreferrer\">Forrester\u2019s Total Economic Impact (TEI) stud<\/a>y commissioned by Mailgun to evaluate our platform and services in 2023, Forrester found that, over the course of three years, <b>Sinch Mailgun delivered a 264% return on investment (ROI) and a $454K net present value (NPV).<\/b><\/p>\n\n<p class=\"wp-block-paragraph\">ROI and customer satisfaction can tell us a lot about deliverability. It\u2019s one thing to land in the inbox, it\u2019s another to provide quality messaging to subscribers that leads to conversions or meaningful connections. Engagement is a bit part of the deliverability picture.<\/p>\n\n<h2 class=\"wp-block-heading\">The challenges of email deliverability<\/h2>\n\n<p class=\"wp-block-paragraph\">Email deliverability is sensitive and can feel kind of superstitious. It\u2019s like that old sailor\u2019s adage, <i>red sky at night, sailor\u2019s delight, <\/i>where subtle changes in atmosphere can be telltale signs of an incoming storm.<\/p>\n\n<p class=\"wp-block-paragraph\">The biggest deliverability hurdles exist because mailbox providers, postmasters, and even ESPs all aim to automate the filtering of actual useful content from spam. It\u2019s very easy to be mistaken for spam if you don\u2019t know how to navigate deliverability, and this can greatly impact engagement.<\/p>\n\n<p class=\"wp-block-paragraph\">In our deliverability survey, we found that:<\/p>\n\n<ul class=\"wp-block-list\">\n<li>40% of senders who prioritize deliverability say the biggest benefit is Improved customer satisfaction.<\/li>\n\n\n\n<li>Among senders who\u2019ve been blocklisted, Delays for important messages was the biggest negative impact at 33.5%.<\/li>\n\n\n\n<li>Another 22% said the biggest impact of getting blocklisted was Dissatisfied customers.<\/li>\n<\/ul>\n\n<p class=\"wp-block-paragraph\"><b>The number one challenge for senders is understanding all the elements at play.<\/b> Email deliverability is ultimately built through a combination of technical requirements and engagement strategies that senders need to know about:<\/p>\n\n<ul class=\"wp-block-list\">\n<li><b>Sender reputation: <\/b>Your sender reputation is like your email credit score, and it\u2019s impacted by many deliverability aspects. Factor one is your <a href=\"https:\/\/www.mailgun.com\/fr\/blog\/deliverability\/adresses-ip-dediees-et-partagees-laquelle-choisir\/\" target=\"_tabs\" rel=\"noopener noreferrer\">IP address and domain health.<\/a><\/li>\n\n\n\n<li><b>Authentication: <\/b>Along with your IP\/domain health, authentication is a major contributor to your sender reputation. <a href=\"https:\/\/www.mailgun.com\/fr\/blog\/deliverability\/authentification-des-emails-votre-carte-identite-pour-envoi\/\" target=\"_tabs\" rel=\"noopener noreferrer\">Authentication protocols<\/a> like SPF, DMARC, and DKIM help prove to ISPs that you are a legitimate sender by verifying your sender identity through certificates and encryption.<\/li>\n\n\n\n<li><b>List health: <\/b>List hygiene is key to good deliverability. In email, <a href=\"https:\/\/www.mailgun.com\/blog\/deliverability\/how-to-manage-your-email-list\/\" target=\"_tabs\" rel=\"noopener noreferrer\">a clean list<\/a> is built organically, not bought. Strong lists are regularly validated and maintained with tools like email verifications or processes like sunset policies to ensure that inactive users or invalid addresses don\u2019t count against you.<\/li>\n\n\n\n<li><b>Subscriber engagement: <\/b>How your subscribers interact with your messages influences where ISPs place them in the inbox. If your users mark you as spam, you can bet that\u2019s where you\u2019ll end up landing. That\u2019s why understanding and carefully monitoring email metrics is important.<\/li>\n<\/ul>\n\n<p class=\"wp-block-paragraph\">But that\u2019s not it. On top of knowing what impacts your deliverability, you need to <b>understand the best practices<\/b> across each of these areas. What\u2019s the right way of building an email list? How should handle disengaged subscribers? What are the best authentication practices for your email program?<\/p>\n\n<p class=\"wp-block-paragraph\">Finally, you need to be able to read your <a href=\"https:\/\/www.mailgun.com\/fr\/blog\/deliverability\/statistiques-phares-delivrabilite\/\" target=\"_tabs\" rel=\"noopener noreferrer\">email metrics<\/a> and track any slight fluctuation in engagement to detect potential issues. For example, a sudden increase in <a href=\"https:\/\/www.mailgun.com\/fr\/blog\/deliverability\/ameliorer-votre-taux-de-rebond\/\" target=\"_tabs\" rel=\"noopener noreferrer\">bounce rate<\/a> <i>can<\/i> mean you might be on a blocklist, but it could also mean you haven\u2019t properly warmed your IP, that you\u2019ve purchased emails, or have suddenly increased your sending and the volume is being flagged as suspicious.<\/p>\n\n<h2 class=\"wp-block-heading\">Navigating the ins and outs of email deliverability<\/h2>\n\n<p class=\"wp-block-paragraph\">As you\u2019re probably realizing, deliverability can be a pain in the keester. Especially if it\u2019s a relatively new concept to your team.<\/p>\n\n<p class=\"wp-block-paragraph\">We\u2019ve talked a lot about best practices and some of the elements that impact email deliverability. Now, let\u2019s talk about how to implement it, what are some good deliverability resources, and when you should think about lighting up the bat signal.<\/p>\n\n<h3 class=\"wp-block-heading\">Build a culture of continuous deliverability education<\/h3>\n\n<p class=\"wp-block-paragraph\">If you\u2019re going to go it alone, we won\u2019t stop you. Deliverability is something that can be learned and if you have the internal resources to dedicate, managing your email deliverability in-house can be successful.<\/p>\n\n<p class=\"wp-block-paragraph\">Step one is to <a href=\"text=Deliverability%2520is%2520the%2520rate%2520in,a%2520properly%2520implemented%2520email%2520program.\" target=\"_tabs\" rel=\"noopener noreferrer\">understand the basics.<\/a> Take the factors of email deliverability we outlined earlier and look at your current sending practices. A great place to start is by analyzing what you\u2019re currently doing that works well, and what might be hurting you.<\/p>\n\n<p class=\"wp-block-paragraph\">Step two is to get a bird\u2019s eye view of how deliverability works and is being implemented by senders on a larger scale. Staying connected and up to date on deliverability trends is key to ensuring you adapt your strategy to the latest developments from mailbox providers and consumer habits.<\/p>\n\n<p class=\"wp-block-paragraph\">Wondering how to do that?
