It\u2019s awful. But the worst is when you simply get ghosted. They stop answering your texts and calls and simply fall off the face of the earth. You\u2019re left wondering if they\u2019re just temporarily gone or if the breakup is permanent. In this case, it\u2019s sometimes best to just step up and either clarify your relationship or sever ties for good.<\/p>\n\n<p class=\"wp-block-paragraph\"><b>Businesses and their email subscribers are also in a relationship in the email marketing world. <\/b>And sometimes, you end up in that gray zone where you\u2019re unsure if your subscriber has broken up with you. They no longer open your emails and no longer engage with your messages. In this case, you can reach out to your subscriber and explicitly invite them back. Or, you might need to let your customer go.<\/p>\n\n<p class=\"wp-block-paragraph\">Your company can implement a \u201c<b>sunset policy<\/b>\u201d to clean unengaged contacts from your mailing lists.

The goal of implementing a sunset policy is to <b>improve your engagement rates and <\/b><a href=\"https:\/\/www.mailgun.com\/de\/blog\/deliverability\/email-zustellrate-verbessern\/\" target=\"_tabs\" rel=\"noopener noreferrer\"><b>email deliverability<\/b><\/a><b>.<\/b><\/p>\n\n<p class=\"wp-block-paragraph\">You can implement a sunset policy to determine when the \u201csun sets\u201d on your relationship with disengaged contacts. Sunset policies help you focus on communicating with engaged customers and bid a quick <i>hasta la vista <\/i>to unengaged subscribers cluttering up your mailing list.<\/p>\n\n<h2 class=\"wp-block-heading\">Why are sunset policies important?<\/h2>\n\n<p class=\"wp-block-paragraph\">While all use cases and businesses are different, sunset policies are important to your email marketing efforts. In brief, sunset policies:<\/p>\n\n<ul class=\"wp-block-list\">\n<li>Optimize your mailing list<\/li>\n\n\n\n<li>Conveniently clean your mailing list<\/li>\n\n\n\n<li>Structure your list cleaning<\/li>\n\n\n\n<li>Improve email deliverability<\/li>\n<\/ul>\n\n<p class=\"wp-block-paragraph\">Let\u2019s go over each of these in more detail below.<\/p>\n\n<h3 class=\"wp-block-heading\">Optimize sending lists<\/h3>\n\n<p class=\"wp-block-paragraph\">Preventative maintenance of your contact lists, like a sunset policy, ensures you\u2019re sending emails to recipients who want your messages. An <a href=\"https:\/\/www.mailgun.com\/blog\/deliverability\/how-to-manage-your-email-list\/\" target=\"_tabs\" rel=\"noopener noreferrer\"><b>optimized sending list<\/b><\/a><b> leads to better engagement<\/b>, with the end goal of improving deliverability and inboxing. We\u2019ll explain why engagement is so critical to good deliverability and why it all starts with a healthy mailing list.<\/p>\n\n<h3 class=\"wp-block-heading\">Conveniently clean your mailing list<\/h3>\n\n<p class=\"wp-block-paragraph\">Automation is never a bad thing! Implementing a sunset policy allows you to automate mailing list cleaning. You can set up your sunset on a particular schedule or with <a href=\"https:\/\/www.mailgun.com\/de\/blog\/email\/trigger-email-programm\/\" target=\"_tabs\" rel=\"noopener noreferrer\">certain triggers<\/a> as you move through your email marketing campaign.<\/p>\n\n<h3 class=\"wp-block-heading\">Structure your list cleaning<\/h3>\n\n<p class=\"wp-block-paragraph\">Sunset policies structure your list and give you a clear idea of which subscribers to let go or keep to maximize your deliverability rates and provide accurate reporting.<\/p>\n\n<h3 class=\"wp-block-heading\">Improve your email deliverability<\/h3>\n\n<p class=\"wp-block-paragraph\">You\u2019ve designed a <a href=\"https:\/\/www.mailgun.com\/blog\/product\/mailgun-template-builder\/\" target=\"_tabs\" rel=\"noopener noreferrer\">great HTML template<\/a> and prepared a great email campaign, but there are no guarantees your email subscribers will receive, much less engage with, your email. Email delivery can be a bit of a crapshoot based on the whims of Internet Service Providers (ISPs).<\/p>\n\n<p class=\"wp-block-paragraph\">You may think engagement isn\u2019t very important if you\u2019re making it into the inbox, but the truth is that your email deliverability needs engaged contacts. ISPs use <a href=\"https:\/\/www.mailgun.com\/de\/blog\/email\/email-metriken\/\" target=\"_tabs\" rel=\"noopener noreferrer\">engagement metrics<\/a> (like open rates and click-through rates) to decide what messages make it into the inbox and what they consider spam.<\/p>\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" class=\"wp-image-2883\" width=\"1297\" height=\"684\" src=\"https:\/\/www.mailgun.com\/wp-content\/uploads\/2025\/07\/MG-Infographics-Logs-Analytics-02-3.png\" alt=\"Metrics and tags displayed on a bar chart.\" \/><figcaption class=\"wp-element-caption\"><em>Using tags helps you visualize email types and audiences.<\/em><\/figcaption><\/figure>\n\n<p class=\"wp-block-paragraph\">If you have a <a href=\"https:\/\/www.mailgun.com\/de\/blog\/email\/der-weg-zu-e-mail-engagement-in-2021-wichtige-erkenntnisse\/\" target=\"_tabs\" rel=\"noopener noreferrer\">healthy level of engagement<\/a>, you\u2019ll enter a cycle of ISP-approved deliverability into the inbox, which results in more engagement, and even better deliverability. If you have low or no engagement, prepare to meet the spam folder. This means bracing for the trifecta of low engagement, deliverability issues, and a damaged brand reputation.<\/p>\n\n<p class=\"wp-block-paragraph\"><b>Good email engagement rates mean good deliverability.<\/b> Bad email engagement rates mean bad deliverability. It\u2019s as simple as that.<\/p>\n\n<p class=\"wp-block-paragraph\">When it comes to your email program, <a href=\"https:\/\/www.mailgun.com\/de\/blog\/deliverability\/promote-strategic-email-engagement\/\" target=\"_tabs\" rel=\"noopener noreferrer\">engaged subscribers are the people who will open and interact<\/a> with your emails through their consumer lifecycle. Focus on your engaged email subscribers to keep your engagement high, your ISPs happy, and your messages at the top of the inbox where they belong.<\/p>\n\n<h2 class=\"wp-block-heading\">What should I consider when implementing an email sunset policy?<\/h2>\n\n<p class=\"wp-block-paragraph\">As we mentioned above, every business and use case is different, and as such, requires different sunset policies. Here are a few things you should establish before implementing a sunset policy:<\/p>\n\n<ul class=\"wp-block-list\">\n<li><b>Define what a disengaged contact is for your business. <\/b>Every situation is different, but you can use statistics from your email engagement metrics to determine when you consider a contact to be disengaged. For instance, you can consider the number of emails delivered since their last engagement or their last email open date.<\/li>\n\n\n\n<li><b>Determine how long it\u2019s appropriate for your company to send messages to an unengaged recipient. <\/b>Just because your subscriber has dropped off in their email engagement doesn\u2019t mean they\u2019re gone for good. Based on your email engagement metrics and the email marketing team\u2019s recommendations, decide how long it\u2019s appropriate to re-engage contacts before letting the sunset policy kick in.<\/li>\n<\/ul>\n\n<p class=\"wp-block-paragraph\"><b>Decide if you\u2019ll send unengaged customers a final permission pass to unsubscribe or a goodbye series, asking them if they\u2019d like to continue to receive mail. <\/b><i>Do not go gentle into that good night \u2013<\/i> it\u2019s worth trying one last time to win back your disengaged contacts. You can do this by explicitly letting them know they\u2019re being removed from your mailing list on a certain date. You can also encourage them to re-engage instead of leaving within the same message, as shown below.<\/p>\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" class=\"wp-image-4455\" width=\"1630\" height=\"734\" src=\"https:\/\/www.mailgun.com\/wp-content\/uploads\/2025\/07\/BBC-Careers-Hub.png\" alt=\"BBC Careers Hub profile reactivation email.\" srcset=\"https:\/\/www.mailgun.com\/wp-content\/uploads\/2025\/07\/BBC-Careers-Hub.png 1630w, https:\/\/www.mailgun.com\/wp-content\/uploads\/2025\/07\/BBC-Careers-Hub-1024x461.png 1024w, https:\/\/www.mailgun.com\/wp-content\/uploads\/2025\/07\/BBC-Careers-Hub-768x346.png 768w, https:\/\/www.mailgun.com\/wp-content\/uploads\/2025\/07\/BBC-Careers-Hub-1536x692.png 1536w, https:\/\/www.mailgun.com\/wp-content\/uploads\/2025\/07\/BBC-Careers-Hub-300x135.png 300w\" sizes=\"(max-width: 1630px) 100vw, 1630px\" \/><\/figure>\n\n<h3 class=\"wp-block-heading\">How do you implement a sunset policy?<\/h3>\n\n<p class=\"wp-block-paragraph\">Once you\u2019ve established the above definitions, let\u2019s look at how to implement your policy:<\/p>\n\n<p class=\"wp-block-paragraph\">1. <b>Segment your mailing list based on your rules of engagement. <\/b>Sort your email subscribers into activity groups to determine email frequency. For example:<\/p>\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>\nActi\u00advity grou\u00adp\n<\/th><th>\nLeve\u00adl of enga\u00adgement\n<\/th><\/tr><\/thead><tbody><tr><td>\nNon-engaged\n<\/td><td>\nNo emai\u00adls\n<\/td><\/tr><tr><td>\nSome\u00adwhat enga\u00adged\n<\/td><td>\n\u00bc emai\u00adls\n<\/td><\/tr><tr><td>\nWell\u00ad enga\u00adged\n<\/td><td>\n\u00bd emai\u00adls\n<\/td><\/tr><tr><td>\nSupe\u00adr enga\u00adged\n<\/td><td>\n\u00be emai\u00adls\n<\/td><\/tr><tr><td>\nAlwa\u00adys enga\u00adged\n<\/td><td>\nAll emai\u00adls\n<\/td><\/tr><\/tbody><\/table><\/figure>\n\n<p class=\"wp-block-paragraph\">Remember, these are only guidelines, they are not hard rules.

In this video, a pair of experts explain why identifying unengaged email subscribers is an important part of maintaining list hygiene. \\n\\nNick Schafer and Ashley Rodgriguez of Sinch Mailgun believe sunset policies are vital to every email program. An email sunset policy involves setting timeframes and thresholds for contacts who are no longer opening or clicking what you\\u2019re sending to their inbox. \\n\\nMailbox providers like Gmail, Yahoo Mail, and Outlook pay attention to whether people are engaging with your email marketing campaigns. So, segmenting or removing unengaged subscribers from your list ultimately supports improved email deliverability. That may seem counterintuitive. How could a smaller email list deliver better results? The truth is subscribers who are no longer engaging aren\\u2019t doing your business any favors. With a sunset policy, you can proactively unsubscribe those people before problems arise. \\n\\nFind out why Nick and Ashley say sometimes enough is enough.
