Most of these reasons lie outside of your control as an email marketer, as you\u2019ll see in a moment. <b>But what you <\/b><b><i>can<\/i><\/b><b> control is how you respond.<\/b><\/p>\n\n<p class=\"wp-block-paragraph\">Keeping your bounce rate as low as possible, especially your hard bounces, plays a big role in maintaining a strong email reputation. That helps you achieve consistently high deliverability, and that means better results.<\/p>\n\n<p class=\"wp-block-paragraph\">If you don\u2019t attend to your email bounces, and just keep sending messages to non-existent email addresses, you increase your chances of being flagged as a spammer and getting blocklisted and that will keep many of your actual, interested subscribers from receiving your emails, too.<\/p>\n\n<p class=\"wp-block-paragraph\">So, keeping control over your bounces is a big part of managing a successful email program.<\/p>\n\n<p class=\"wp-block-paragraph\">Why are bounces such a hard problem to solve? This is largely due to the fact that, in some cases, a bounced email address really is a technical error that can be remedied with some due diligence. Still, with a quick fix, your bounces should go down, right?<\/p>\n\n<p class=\"wp-block-paragraph\">Well, that depends on what type of email bounces you\u2019re getting.<\/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-6592\"><p class=\"h5 m-0\" id=\"toc-title-6592\">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=\"#bounce-rates-web-vs-email-metrics\">Bounce rates: Web vs email metrics<\/a><a class=\"scrollme link-body-color\" href=\"#what-is-a-high-email-bounce-rate\">What is a high email bounce rate?<\/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=\"#hard-bounces\">Hard bounces<\/a><a class=\"scrollme link-body-color\" href=\"#the-main-reasons-for-a-hard-bounce\">The main reasons for a hard bounce<\/a><a class=\"scrollme link-body-color\" href=\"#what-do-i-do-about-a-sudden-increase-in-hard-email-bounces\">What do I do about a sudden increase in hard email bounces?<\/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=\"#soft-bounces\">Soft bounces<\/a><a class=\"scrollme link-body-color\" href=\"#the-main-reasons-for-a-soft-bounce\">The main reasons for a soft bounce<\/a><a class=\"scrollme link-body-color\" href=\"#what-can-you-do-about-a-sudden-increase-in-soft-bounces\">What can you do about a sudden increase in soft bounces?<\/a><a class=\"scrollme link-body-color\" href=\"#can-my-esp-place-limits-on-my-account\">Can my ESP place limits on my account?<\/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=\"#email-bounces-can-be-solved\">Email bounces can be solved<\/a><a class=\"scrollme link-body-color\" href=\"#monitor-your-bounce-metrics-with-bounce-classification\">Monitor your bounce metrics with Bounce Classification<\/a><\/div><\/div><\/nav>\n<h2 class=\"wp-block-heading\">Bounce rates: Web vs email metrics<\/h2>\n\n<p class=\"wp-block-paragraph\">Before we get into it, let\u2019s clarify what we mean by a bounce rate. There may be some confusion here because website traffic data also includes a metric called a \u201cbounce rate.\u201d The bounce rates you see in Google Analytics have very little in common with email bounce rates.<\/p>\n\n<p class=\"wp-block-paragraph\">A website bounce rate measures how many visitors come to your site, look at one page, and then leave without taking any actions or visiting any other pages. A high web bounce rate usually means your content isn\u2019t very engaging, your site is loading slowly or giving off red flags like security warnings, you\u2019re attracting the wrong audience, or you\u2019re just giving visitors little reason to browse further.<\/p>\n\n<p class=\"wp-block-paragraph\"><b>An email bounce rate measures how many emails do not get delivered compared to how many emails you send. <\/b>If you send 5000 emails to your list, and 50 of them bounce back and don\u2019t get delivered, you would have a fairly acceptable bounce rate of 1%. A high email bounce rate is a sign that you need to conduct some list cleaning.<\/p>\n\n<h3 class=\"wp-block-heading\">What is a high email bounce rate?<\/h3>\n\n<p class=\"wp-block-paragraph\">If your email bounce rate is too high, a mailbox service provider (MBP) can penalize your sender reputation. They take it as an indication that you\u2019re not maintaining good list health or are acquiring subscribers from less-than-legitimate sources.<\/p>\n\n<p class=\"wp-block-paragraph\">For this reason, <b>the general recommendation is to keep your bounce rate under 2%, <\/b>if possible. Once you creep above the 2% bounce rate benchmark, you need to perform some email list cleaning and get your bounce rate back down.<\/p>\n\n<p class=\"wp-block-paragraph\"><b>Why not go for a zero bounce rate? <\/b>Well, that\u2019s certainly the goal, but it\u2019s not exactly realistic. Bounced emails will happen eventually. People abandon addresses because they change jobs or enter a new phase of life. Some bounces are temporary issues and have nothing to do with maintaining a clean contact list. Even a full mailbox could cause bounces. ISPs understand this and there\u2019s a bit of grace.<\/p>\n\n<p class=\"wp-block-paragraph\">However, some email addresses will keep bouncing no matter what &#8211; like a bouncy ball with enough energy to keep bouncing for all eternity. (Sorry for the dramatics.) So, how do you know which type of email bounces to worry about the most? It comes down to <b>hard bounces vs soft bounces.<\/b><\/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\"> All email bounces impact your deliverability and your sender reputation. Unfortunately, seeing how your bounce rate impacts your deliverability isn\u2019t possible <a href='https:\/\/www.mailgun.com\/de\/products\/inbox\/deliverability\/blocklist-monitoring-service\/'>without specific tools.<\/a><\/div>\r\n    <\/div>\r\n\n<h2 class=\"wp-block-heading\">Hard bounces<\/h2>\n\n<p class=\"wp-block-paragraph\"><b>With a hard bounce, the email address is undeliverable and isn\u2019t likely to become deliverable in the future.<\/b>\u00a0Hard bounces, also known as permanent failures, mean that the message is undeliverable due to some sort of unchangeable, permanent reason. <b>Common reasons for hard bounces are invalid email addresses, the receiving server no longer exists, misspelled domain names or recipient addresses, etc.<\/b> Most email providers \u2013 Mailgun included \u2013 will stop attempting to send hard bounce messages after the first attempt. If it has nowhere to go, not even <i>we <\/i>can deliver it. also known as permanent failures, mean that the message is undeliverable due to some sort of unchangeable, permanent reason. Most email providers \u2013 Mailgun included \u2013 will stop attempting to send hard bounce messages after the first attempt. If it has nowhere to go, not even we can deliver it.<\/p>\n\n<h3 class=\"wp-block-heading\">The main reasons for a hard bounce<\/h3>\n\n<h4 class=\"wp-block-heading\">Non-existent email address<\/h4>\n\n<p class=\"wp-block-paragraph\">How can an email show up on your list if it doesn\u2019t exist? It may have been real before, but perhaps that recipient closed their email account. If it was a work email, they may have left their job. Eventually, abandoned addresses may be used as <a href=\"https:\/\/www.mailgun.com\/de\/blog\/deliverability\/spam-traps-what-you-should-know\/\" target=\"_tabs\" rel=\"noopener noreferrer\">spam traps.<\/a><\/p>\n\n<p class=\"wp-block-paragraph\">So, if you keep sending to non-existent email addresses, you\u2019ll not only have a higher bounce rate, but you may accidentally send to a spam trap and end up on a blocklist. <\/p>\n\n<h4 class=\"wp-block-heading\">Email typos<\/h4>\n\n<p class=\"wp-block-paragraph\">A real person may have opted into your email list but just typed their address wrong. If this happens, sometimes you can correct it. For example, if you notice their email address ends with gmail.co, you could manually add the missing \u2018m.\u2019 The same goes for other common typos. But if they mistype the personalized portion of their address, catching a typo will be much harder.<\/p>\n\n<p class=\"wp-block-paragraph\">Of course, manually fixing little subscriber typos is finicky, and even a bit risky. You can&#8217;t be 100% sure that person truly meant to give you consent to send them email marketing campaigns. That&#8217;s why a solution like <a href=\"https:\/\/www.mailgun.com\/de\/products\/inbox\/inboxready\/\" target=\"_tabs\" rel=\"noopener noreferrer\">Mailgun Optimize&#8217;s email validation API<\/a> can help. It catches common typos and provides potential subscribers with suggest fixes.<\/p>\n\n<h4 class=\"wp-block-heading\">You\u2019ve been blocked<\/h4>\n\n<p class=\"wp-block-paragraph\">Some mailbox service providers block emails perceived to be commercial in nature. Again, this is most likely with certain companies or institutions, such as government entities. You may be able to get around that by contacting these subscribers through other means and asking them to add your sending email address to a \u201csafe senders\u201d list. <\/p>\n\n<p class=\"wp-block-paragraph\">In other cases, recipients themselves can block you, perhaps because they don\u2019t want to receive emails from you but also don\u2019t want to go through the unsubscribe process for some reason. If you continue seeing this as the reason for an email bounce, it\u2019s best to just remove that subscriber from your list.<\/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\"> A common misconception is that nothing you do will change this bounce, so some senders think it\u2019s best to just throw those email addresses off your lists or CRM. Deleting customer data is not recommended. Instead, emails that hard bounce should be added to a suppression list <a href='https:\/\/help.mailgun.com\/hc\/en-us\/articles\/360012287493-Understanding-Mailgun-Suppressions-Bounced-Complained-Unsubscribed-And-Whitelisted-'>(Mailgun does this automatically).<\/a><\/div>\r\n    <\/div>\r\n\n<h3 class=\"wp-block-heading\">What do I do about a sudden increase in hard email bounces?<\/h3>\n\n<p class=\"wp-block-paragraph\">When it comes to hard bounces, you shouldn\u2019t see a sudden increase at any point while sending emails. If you are sending to a list for the first time without validating it first, you might see a larger hard bounce rate due to factors like typos. As we stated earlier, just add those addresses to a <a href=\"https:\/\/documentation.mailgun.com\/docs\/mailgun\/user-manual\/smtp-protocol\/\" target=\"_tabs\" rel=\"noopener noreferrer\">suppression list<\/a> to bring your hard bounces down. It\u2019s as easy as that, with (hopefully) no profanity involved.<\/p>\n\n<p class=\"wp-block-paragraph\">To avoid them entirely, you can <a href=\"https:\/\/www.mailgun.com\/de\/blog\/product\/bulk-verifications-accurate-fast\/\" target=\"_tabs\" rel=\"noopener noreferrer\">verify an existing list <\/a> or add a <a href=\"https:\/\/www.mailgun.com\/de\/blog\/email\/double-opt-in-mit-php-mailgun\/\" target=\"_tabs\" rel=\"noopener noreferrer\">double opt-in feature<\/a> to your forms to ensure users\u2019 emails are correct.

Suddenly, you receive a hard bounce from this email address. The customer still wants to hear from you, so deleting their record would mean losing a customer. Instead, we use this hard bounce as a reminder to prompt them to update their valid email address another way, either in-app or using a <a href=\"https:\/\/www.sinch.com\/products\/apis\/messaging\/\" target=\"_tabs\" rel=\"noopener noreferrer\">CPaaS method.<\/a><\/p>\n\n<h2 class=\"wp-block-heading\">Soft bounces<\/h2>\n\n<p class=\"wp-block-paragraph\">Now that we\u2019ve got through the hard stuff (sorry, bad pun), let\u2019s talk <a href=\"https:\/\/www.mailgun.com\/de\/blog\/soft-bounces-mysteries-failures\" target=\"_tabs\" rel=\"noopener noreferrer\">soft bounces.<\/a> <b>These temporary failures cannot be delivered due to some kind of issue that will likely resolve itself.<\/b> What kind of temporary circumstance? Anything from the email message being too large to the recipient\u2019s email server being down. <\/p>\n\n<h3 class=\"wp-block-heading\">The main reasons for a soft bounce<\/h3>\n\n<h4 class=\"wp-block-heading\">Mailbox full<\/h4>\n\n<p class=\"wp-block-paragraph\">Most mailbox providers give quite a large amount of room for each account. A full mailbox suggests that the recipient has stopped using that email address. It could also mean they just don\u2019t delete old emails frequently enough, or that they have a lot of images or rich media in emails taking up space on the server.<\/p>\n\n<h4 class=\"wp-block-heading\">Size of email<\/h4>\n\n<p class=\"wp-block-paragraph\">Some mailbox providers place limits on the size of emails they\u2019ll accept, in terms of megabytes. So, if you\u2019re sending out emails with lots of high-resolution images or huge attachments, you run the risk of them not being delivered. The simplest way to avoid this is to always optimize your images. <\/p>\n\n<p class=\"wp-block-paragraph\">You can also <a href=\"https:\/\/www.mailgun.com\/de\/products\/inbox\/inboxready\/\" target=\"_tabs\" rel=\"noopener noreferrer\">test for inbox placement and email deliverability<\/a> before sending a major campaign. <\/p>\n\n<h4 class=\"wp-block-heading\">Receiving email server issues<\/h4>\n\n<p class=\"wp-block-paragraph\">Here, the recipient\u2019s email server might be down or be having other issues preventing it from receiving messages at that time. After a while, it will work again and the email will go through.<\/p>\n\n<p class=\"wp-block-paragraph\">A recipient\u2019s mail server may also bounce a message back to the sender if it fails email <a href=\"https:\/\/www.mailgun.com\/de\/blog\/deliverability\/e-mail-authentifizierung-ihr-ausweis-fuer-den-versand\/\" target=\"_tabs\" rel=\"noopener noreferrer\">authentication protocols like SPF, DKIM, and DMARC enforcement.<\/a><\/p>\n\n<p class=\"wp-block-paragraph\">There isn\u2019t any one solution for soft bounces, but the email still can\u2019t be delivered to the recipient\u2019s mailbox at that point in time. In these cases, <b>most ESPs will attempt delivery a few more times in case circumstances change and then stop if the email continues to bounce.<\/b><\/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\"> Bounced back emails are just one of many possible outcomes when sending an email \u2013 <a href='https:\/\/www.mailgun.com\/de\/blog\/email\/email-metriken\/'>read our ultimate guide<\/a> to email metrics to better understand your email stats.<\/div>\r\n    <\/div>\r\n\n<h3 class=\"wp-block-heading\">What can you do about a sudden increase in soft bounces?<\/h3>\n\n<p class=\"wp-block-paragraph\">If you find yourself in this situation, the first thing you should look at is your list.

Usually, there is something you are doing that would adversely affect your reputation or others if you\u2019re on a shared IP. Allowing risky sending to continue from a shared sending IP hurts other well-meaning senders, and an ESP needs to take care of every sender.<\/p>\n\n<p class=\"wp-block-paragraph\">There are other cases beyond soft bounces where you can find yourself limited while sending. Sending too many messages at one time <a href=\"https:\/\/www.mailgun.com\/de\/blog\/deliverability\/domain-warmup-reputation-vor-dem-versand-aufbauen\/\" target=\"_tabs\" rel=\"noopener noreferrer\">without a proper warm up<\/a>, hitting <a href=\"https:\/\/www.mailgun.com\/de\/blog\/deliverability\/spamfallen\/\" target=\"_tabs\" rel=\"noopener noreferrer\">spam filters with risky sending practices<\/a>, or <a href=\"https:\/\/www.mailgun.com\/de\/blog\/deliverability\/eine-email-liste-richtig-aufbauen\/\" target=\"_tabs\" rel=\"noopener noreferrer\">recipients that did not consent <\/a> to your email messages and complain are a few examples of factors that affect your sending limits, too.<\/p>\n\n<h2 class=\"wp-block-heading\">Email bounces can be solved<\/h2>\n\n<p class=\"wp-block-paragraph\">We emphasize this a lot when we talk about bounce rates, but we\u2019ll reiterate here \u2014 the problem isn\u2019t your bounces, it\u2019s what\u2019s causing them in the first place. Bounces are almost always a symptom of out-of-date or poor sending practices, and that means <a href=\"https:\/\/www.mailgun.com\/de\/blog\/diving-head-first-into-the-inbox\" target=\"_tabs\" rel=\"noopener noreferrer\">poor deliverability<\/a>.
