So, what is key for developers? What aspects of deliverability are within their control?<\/p>\n\n<p class=\"wp-block-paragraph\">The first thing to know is that deliverability is hinged on performance. From how optimized your sending infrastructure is to how well your messages are coded, there are many pieces separate from the authentications and best practices that marketers pursue.<\/p>\n\n<p class=\"wp-block-paragraph\">But before we dive in, let\u2019s start with the basics. What is deliverability?<\/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-1086\"><p class=\"h5 m-0\" id=\"toc-title-1086\">Inhaltsverzeichnis<\/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-importance-of-deliverability\">Understanding the importance 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=\"#how-deliverability-and-dev-are-connected\">How deliverability and dev are connected<\/a><a class=\"scrollme link-body-color\" href=\"#choose-the-right-tech-stack\">Choose the right tech stack<\/a><a class=\"scrollme link-body-color\" href=\"#evaluate-the-pros-and-cons-of-different-technologies\">Evaluate the pros and cons of different technologies<\/a><a class=\"scrollme link-body-color\" href=\"#consider-scalability-and-future-growth\">Consider scalability and future growth<\/a><a class=\"scrollme link-body-color\" href=\"#incorporate-automation\">Incorporate automation<\/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=\"#how-developers-enhance-deliverability\">How developers enhance deliverability<\/a><a class=\"scrollme link-body-color\" href=\"#optimizing-load-times-and-performance\">Optimizing load times and performance<\/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=\"#future-trends-and-emerging-tech\">Future trends and emerging tech<\/a><\/div><\/div><div class=\"d-flex mt-3\"><div class=\"w-auto fw-bold text-accent d-flex me-2\">05<\/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\">Understanding the importance of deliverability<\/h2>\n\n<p class=\"wp-block-paragraph\">In short, deliverability is email jargon for getting your message into the inbox.<\/p>\n\n<p class=\"wp-block-paragraph\">Beyond that, though, deliverability centers around increasing engagement and email ROI. Now, we know that ROI may not be a primary concern for all devs, but deliverability is more than just a wallet issue, <b>deliverability is a product of performance.<\/b> And we\u2019re not talking marketing metrics like bounce rates, we\u2019re talking infrastructure efficiency, file sizes, caching mechanisms, cross-platform compatibility, and responsive designs.<\/p>\n\n<p class=\"wp-block-paragraph\">Deliverability isn\u2019t just about <i>if <\/i>your email makes it to the inbox, it\u2019s about the condition in which it arrives.<\/p>\n\n<p class=\"wp-block-paragraph\"><b>Here&#8217;s an example from the email dev perspective:<\/b> The majority of email clients don\u2019t support many things that <i>can <\/i>be done with HTML. So, in addition to marketing\u2019s best practices for deliverability you have to be pragmatic with how you develop your emails. This means testing your messages outside of your local environment with an <a href=\"https:\/\/www.mailgun.com\/de\/products\/inbox\/features\/email-preview\/\" target=\"_tabs\" rel=\"noopener noreferrer\">email preview tool<\/a> to ensure compatibility across different operating systems and devices.<\/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\"> Coding with HTML and keeping deliverability in mind can be a challenge.

When it comes to email, development goes way beyond the coding language used to design the actual emails. Infrastructure engineers are the ones actually optimizing performance at scale, and their role is critical to strong email deliverability.<\/p>\n\n<p class=\"wp-block-paragraph\">Here are a few things to consider:<\/p>\n\n<h3 class=\"wp-block-heading\">Choose the right tech stack<\/h3>\n\n<p class=\"wp-block-paragraph\">Your tech stack is your tools. For email deliverability, that means tools that perform email verification, inbox placement testing, previewing, reputation monitoring, delivery rate monitoring, and monitoring capabilities like blocklist monitoring, spam check, and IP\/domain health.<\/p>\n\n<h3 class=\"wp-block-heading\">Evaluate the pros and cons of different technologies<\/h3>\n\n<p class=\"wp-block-paragraph\">Synergy is something to value when looking into how to compile your toolset. There are a lot of sender agnostic tools out there \u2013 meaning you can partner with one platform for verification and another for IP monitoring. But there are also holistic platforms with built-in integrations for a suite of products.<\/p>\n\n<h3 class=\"wp-block-heading\">Consider scalability and future growth<\/h3>\n\n<p class=\"wp-block-paragraph\">Select a platform or construct your on-premises infrastructure, with growth in mind. One advantage to cloud-based solutions is many have a scale up mindset to meet changing sending needs.<\/p>\n\n<h3 class=\"wp-block-heading\">Incorporate automation<\/h3>\n\n<p class=\"wp-block-paragraph\">Regardless of your toolset, automation should be at the forefront of your strategy. This can apply to your sending strategy like with transactional emails that are triggered by customer action (think password resets, shipping confirmations, etc.)<\/p>\n\n<p class=\"wp-block-paragraph\">You should also consider automations that <a href=\"https:\/\/www.mailgun.com\/de\/blog\/email\/email-list-segmentation\/\" target=\"_tabs\" rel=\"noopener noreferrer\">segment mailing lists<\/a> based on user interaction, a key component to keep email deliverability under control.<\/p>\n\n<h2 class=\"wp-block-heading\">How developers enhance deliverability<\/h2>\n\n<p class=\"wp-block-paragraph\">We\u2019ve covered some of the high-level points of how developers and engineers can impact deliverability. Now, we\u2019re going to give you a playbook for increasing deliverability by improving just one element: speed.<\/p>\n\n<h3 class=\"wp-block-heading\">Optimizing load times and performance<\/h3>\n\n<p class=\"wp-block-paragraph\"><b>Speed is everything. <\/b>Swift load times are critical for messages, given that the average attention span of a user is about <a href=\"https:\/\/www.hostingmanual.net\/3-seconds-how-website-speed-impacts-visitors-sales\/\" target=\"_tabs\" rel=\"noopener noreferrer\">three seconds.<\/a> That\u2019s less time than the five second food on the floor rule.<\/p>\n\n<p class=\"wp-block-paragraph\">While this statistic pertains specifically to website page load speed, you can bet that the inbox is no different \u2013 it\u2019s just a bit harder to track when users click out of a message. And that\u2019s the blind spot with email: Engagement metrics can tell you a lot, but not everything.<\/p>\n\n<p class=\"wp-block-paragraph\">Here are two things email developers can do to improve load times and test you\u2019re their code and performance before sending an email.<\/p>\n\n<ol class=\"wp-block-list\">\n<li><a href=\"https:\/\/www.emailonacid.com\/help-article\/how-do-html-size-image-size-and-pixel-height-impact-previews\/\" target=\"_tabs\" rel=\"noopener noreferrer\">Minimize file sizes<\/a>, optimize images, and implement <a href=\"https:\/\/www.emailonacid.com\/blog\/article\/email-development\/mobile-first-emails\/\" target=\"_tabs\" rel=\"noopener noreferrer\">responsive design principles.<\/a><\/li>\n\n\n\n<li>Ensure cross-platform compatibility with <a href=\"https:\/\/www.mailgun.com\/de\/blog\/deliverability\/how-to-leverage-email-inbox-preview\/\" target=\"_tabs\" rel=\"noopener noreferrer\">inbox preview testing<\/a><\/li>\n<\/ol>\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\"> Need a guide to creating responsive and optimized emails that render across all clients and devices?

Without X-ray vision to peer into the inner workings of mailbox providers, the filters, protocols, and standards of getting into various inboxes remains cloaked in a degree of mystery.<\/p>\n\n<p class=\"wp-block-paragraph\">But that doesn\u2019t mean your email program is defenseless. In fact, the best defense is to be ready to adapt. That\u2019s why paying attention to the optimization of your performance and your HTML practices is so crucial.<\/p>\n\n<p class=\"wp-block-paragraph\">And that\u2019s not the only area where adaptation is needed. Communication is constantly morphing, and businesses need to keep up with the trends to stay relevant \u2013 not just in email, but in omnichannel experiences in general.<\/p>\n\n<p class=\"wp-block-paragraph\">We know in the future technologies like AI and chatbots will continue to play a significant role in enhancing user experiences and engagement \u2013 <b>yet another reason to be really intentional when choosing platforms and tools,<\/b> and deciding how to construct your infrastructure.<\/p>\n\n<h2 class=\"wp-block-heading\">Wrapping up<\/h2>\n\n<p class=\"wp-block-paragraph\">Email isn\u2019t stagnant, and it&#8217;s crucial to stay up to date with the latest trends and technologies. So, make sure you seek out opportunities to expand your knowledge and skills, whether it&#8217;s through courses, experience, or helpful content *wink*.<\/p>\n\n<p class=\"wp-block-paragraph\">If deliverability isn\u2019t already a consideration in how you set up your infrastructure or code your emails, hopefully this post has convinced you that it\u2019s at least something to think about.<\/p>\n\n<p class=\"wp-block-paragraph\">To keep up with the more technical side of emailing, be sure to subscribe to our newsletter for interviews, insights, and inside scoops from our own developers.<\/p>\n    <div data-content-type=\"longform\" class=\"longform-spacings\">\r\n        <div class=\"cta bg-primary rounded-lg px-5 py-6 p-md-7 px-md-6\">\r\n                    <div class=\"form-subscription\">\r\n                            <div class=\"h4 mb-3\">\r\n                    Keep me posted!
