You can follow best practices, but each team and brand has its own limits, preferences, and considerations.<\/p>\n<p>So when it\u2019s time to decide between dedicated IPs vs. shared IPs, you have to consider a few different factors.<\/p>\n<p>Read on to learn what a dedicated IP is and when you should have one so you can make the best decision for your email program.<\/p>\n<h2>What is an IP address?<\/h2>\n<p>An IP address is a website\u2019s version of a street address. The string of numbers identifies a website\u2019s location, although we tend to use the more human-friendly website address for our navigation.<\/p>\n<p>For example, the IP address for www.litmus.com is currently 23.185.0.4.<\/p>\n<p>Every website has an IP address, and your emails are routed through one, too. Each time you send an email, inbox service providers check the sending IP address as one of the factors they use to ensure you are who you say you are.<\/p>\n<p>As a result, your IP address reputation affects your <a rel=\"noopener\" href=\"https:\/\/litmus.com\/community\/learning\/19-deliverability-basics\" target=\"_blank\" rel=\"noopener\">deliverability<\/a>. That will be a recurring theme in this post. There are two types of email IP addresses: a shared IP or a dedicated IP.<\/p>\n<img decoding=\"async\" class=\"alignnone wp-image-34648 size-full\" src=\"https:\/\/www.litmus.com\/wp-content\/uploads\/2021\/09\/Dedicated-IP-flowchart2.png\" alt=\"Shared vs. Dedicated IP Flowchart\" width=\"1544\" height=\"1664\" srcset=\"https:\/\/www.litmus.com\/wp-content\/uploads\/2021\/09\/Dedicated-IP-flowchart2.png 1544w, https:\/\/www.litmus.com\/wp-content\/uploads\/2021\/09\/Dedicated-IP-flowchart2-278x300.png 278w, https:\/\/www.litmus.com\/wp-content\/uploads\/2021\/09\/Dedicated-IP-flowchart2-950x1024.png 950w, https:\/\/www.litmus.com\/wp-content\/uploads\/2021\/09\/Dedicated-IP-flowchart2-768x828.png 768w, https:\/\/www.litmus.com\/wp-content\/uploads\/2021\/09\/Dedicated-IP-flowchart2-1425x1536.png 1425w\" sizes=\"(max-width: 1544px) 100vw, 1544px\" \/>\n<p>With a <b>shared IP<\/b>, your email sends from one of many IPs that your email service provider (<a rel=\"noopener\" href=\"https:\/\/www.litmus.com\/solutions\/esp\/\">ESP<\/a>) manages. All of the companies using that ESP will cycle through the same IP addresses. So, someone else is likely using your assigned IP address(es), too.<\/p>\n<p>With a <b>dedicated IP<\/b>, your email always sends from the same static IP, and your company is the only resident at that address.<\/p>\n\n<div class=\"container pt-3 pb-5\">\n\t<div class=\"row blog-cta-blue  p-4\">\n\t\t<div class=\"col-12 mx-auto\">\n\t\t\t<div class=\"row d-flex align-items-center\">\n\t\t\t<div class=\"col-lg-6 col-12\">\n\t\t\t\t<p class=\"bold fs-4\">Is your infrastructure hurting you?<\/p>\n\t\t\t\t<p>Validity Everest checks your technical setup for errors that affect inbox placement\u2014before they hurt your performance.<\/p>\n\t\t\t\t<button class=\"button-blue arrow\"><a rel=\"noopener\" target=\"_blank\" href=\"https:\/\/www.validity.com\/everest\/infrastructure\/\" class=\"text-white text-decoration-none\">Audit setup<\/a><\/button>\n\t\t\t<\/div><!--col-6-->\n\t\t\t<div class=\"col-6 d-none d-lg-block\">\n\t\t\t\t<img decoding=\"async\" src=\"https:\/\/www.litmus.com\/wp-content\/uploads\/2024\/12\/blog-cta-12172024.svg\" width=\"208\" height=\"171\" alt=\"\">\n\t\t\t<\/div><!--col-6-->\n\t\t\t<\/div> <!--row-->\n\t\t<\/div><!--col-12-->\n\t<\/div><!--row-->\n<\/div><!--container-->\n\t\n\t\t\n\t\n\t\n\t\n\n<p>&nbsp;<\/p>\n<h2>The benefits (and drawbacks) of a dedicated IP<\/h2>\n<p>At first glance, a dedicated IP looks like an enticing option to ensure you have total control over your IP reputation. While that\u2019s true, it\u2019s only part of the story. Here\u2019s what you need to know about using a dedicated email IP address.<\/p>\n<h3>Pro: Other company\u2019s shady email practices won\u2019t affect your deliverability<\/h3>\n<p>The benefit of dedicated IPs that you\u2019ll hear most often is protecting your deliverability from other senders\u2019 practices. Since you\u2019re the only company sending email from an IP address, you have total transparency and control over maintaining IP reputation, and as an extension, your deliverability.<\/p>\n<h3>Con: The full weight of your IP reputation lies on your shoulders<\/h3>\n<p>You need to maintain excellent sending practices on a dedicated IP address because your actions alone determine IP reputation. In the same way that sharing the IP address with shady senders can bring your <a rel=\"noopener\" href=\"https:\/\/www.litmus.com\/blog\/how-to-fix-email-reputation\" rel=\"noopener\" target=\"_blank\">email sender reputation<\/a> down, sharing an address with reputable senders can boost your program.<\/p>\n<p>Without other reliable senders on the IP to act as a crutch, you may feel the effects of sender errors more fully.<\/p>\n<h3>Pro: Your IP address is more likely to get \u201csafelisted\u201d<\/h3>\n<p>If you\u2019re the only company sending email from an IP address, and you\u2019ve proven reliable in the past, organizations may safelist you. This is particularly helpful for B2B companies that need to send transactional and promotional emails to employees within a company.<\/p>\n<h3>Con: You need to warm up the IP address (and keep it warm)<\/h3>\n<p>You start from scratch with a dedicated IP, which means you need to <a rel=\"noopener\" href=\"https:\/\/www.litmus.com\/blog\/how-to-migrate-esps-easily\/\" target=\"_blank\" rel=\"noopener\">warm up your IP address<\/a> to establish a solid foundation for your reputation. And once warmed, your dedicated IP needs to stay consistently warm. Any sudden dips or spikes in email volume will put internet service providers (ISPs) like Yahoo! and Verizon Media on red alert\u2014and you\u2019ll get dinged for that.<\/p>\n<h3>Con: Dedicated IPs require more time and money<\/h3>\n<p>Typically, dedicated IPs cost more than using your ESP\u2019s shared IP pool. Dedicated IPs are helpful for high-volume senders (more on that later), so they may only be a choice on higher-tiered plans.<\/p>\n<h2>Dedicated IP vs. Shared IP: how to choose the best option for your team<\/h2>\n<p>As you can see, there\u2019s a lot more to dedicated IPs than controlling reputation and deliverability. To help you decide which IP setup you should choose (and whether your current one is right for you), we\u2019ve created a decision chart with key factors to consider.<\/p>\n<img decoding=\"async\" class=\"alignnone wp-image-34647 size-full\" src=\"https:\/\/www.litmus.com\/wp-content\/uploads\/2021\/09\/Dedicated-IP-flowchart1.png\" alt=\"Should you use a shared IP or dedicated IP flowchart\" width=\"1543\" height=\"1791\" srcset=\"https:\/\/www.litmus.com\/wp-content\/uploads\/2021\/09\/Dedicated-IP-flowchart1.png 1543w, https:\/\/www.litmus.com\/wp-content\/uploads\/2021\/09\/Dedicated-IP-flowchart1-258x300.png 258w, https:\/\/www.litmus.com\/wp-content\/uploads\/2021\/09\/Dedicated-IP-flowchart1-882x1024.png 882w, https:\/\/www.litmus.com\/wp-content\/uploads\/2021\/09\/Dedicated-IP-flowchart1-768x891.png 768w, https:\/\/www.litmus.com\/wp-content\/uploads\/2021\/09\/Dedicated-IP-flowchart1-1323x1536.png 1323w\" sizes=\"(max-width: 1543px) 100vw, 1543px\" \/>\n<h3>Shared IPs<\/h3>\n<p>Sending from a shared IP is a popular choice that works for a wide range of email teams. This setup is often more affordable and easier to manage than a dedicated IP address. ESPs also want to maintain a positive IP reputation (or their customers would be upset), so most have methods to manage sender standards. You can <a rel=\"noopener\" target=\"_blank\" href=\"https:\/\/postmarkapp.com\/blog\/how-to-check-your-ip-reputation#how-to-check-ip-address-reputation\" target=\"_blank\" rel=\"noopener\">check your email IP address reputation<\/a> if you\u2019re unsure of where you currently stand. It\u2019s also helpful to remember that IP reputation is only one component that impacts deliverability.<\/p>\n<h3>Dedicated IPs<\/h3>\n<p>On the other hand, a dedicated email IP address could be a good fit for your team if:<\/p>\n<p><b>You have a monthly send volume of 100,000 emails or more.<\/b><\/p>\n<p>If you consistently have a high send volume, a dedicated IP will give you more control over your reputation. If your send volume has fluctuations, though, a shared IP will be better to smooth out send volume and prevent raising any deliverability red flags.<\/p>\n<p><b>You\u2019re willing to pay for and maintain a dedicated IP address.<\/b><\/p>\n<p>You\u2019re the sole manager of a dedicated IP address, so you should expect more work and investment than a shared IP address that\u2019s pre-warmed and managed by your ESP.<\/p>\n<p><b>You want to be the sole influence on your IP reputation.<\/b><\/p>\n<p>If you have rock-solid sending practices and want to take full responsibility for your reputation, then you may be ready for a dedicated IP.<\/p>\n<h2>Keep your email deliverability in tip-top shape<\/h2>\n<p>Whether you choose a shared or dedicated IP, it\u2019s important to monitor your deliverability (with an <a rel=\"noopener\" href=\"https:\/\/www.litmus.com\/blog\/email-deliverability-audit\">email deliverability audit<\/a>), since IP reputation is just one piece of the puzzle.\u00a0 Do you use a shared or dedicated IP address?
