In other words, your sender reputation is a major component of your email deliverability. <\/p>\n\n<p class=\"wp-block-paragraph\">In a worst-case scenario (if your reputation is <i>really<\/i> bad), your sender reputation might even land you on an <a href=\"https:\/\/www.mailgun.com\/es\/blog\/deliverability\/como-eliminar-ip-dominio-lista-bloqueo-email\/\" target=\"_tabs\" rel=\"noopener noreferrer\">email blocklist<\/a>. As you can imagine, sender reputation is <i>very important<\/i>. After all, whether you\u2019re sending out a <a href=\"https:\/\/www.mailgun.com\/blog\/email\/what-is-transactional-email-basics\/\" target=\"_tabs\" rel=\"noopener noreferrer\">transactional email<\/a> or an ecommerce campaign, what\u2019s the point of great email design or personalized content if it never gets read?<\/p>\n\n<p class=\"wp-block-paragraph\">ISPs aren\u2019t always 100% transparent when it comes to their parameters for delivery and inbox placement. However, Gmail provides its <a href=\"https:\/\/www.mailgun.com\/es\/blog\/deliverability\/google-postmaster-tools-entender-reputacion-como-remitente\/\" target=\"_tabs\" rel=\"noopener noreferrer\">Google Postmaster Tools<\/a> that give you insight into <a href=\"https:\/\/www.mailgun.com\/es\/blog\/deliverability\/entregabilidad-gmail\/\" target=\"_tabs\" rel=\"noopener noreferrer\">what Gmail thinks<\/a> about your sender reputation. Since Gmail is one of the major players in the email game, you can bet other email clients use similar measures to gauge your sender reputation.<\/p>\n\n<h2 class=\"wp-block-heading\">What determines your sender reputation?<\/h2>\n\n<p class=\"wp-block-paragraph\">Just as in your personal life, it\u2019s never a single action that determines your reputation. In fact, your sender reputation is composed of your IP reputation and your domain reputation over time.<\/p>\n\n<ul class=\"wp-block-list\">\n<li><b>Your IP reputation is based on the IP address from which you send mail. <\/b>If you\u2019re using a <a href=\"https:\/\/www.mailgun.com\/es\/blog\/deliverability\/ip-dedicadas-frente-a-compartidas-cual-usar\/\" target=\"_tabs\" rel=\"noopener noreferrer\">shared IP address<\/a>, your reputation is also influenced by the other senders with whom you share your IP. On the other hand, if you\u2019re on a dedicated IP address, you\u2019re fully responsible for your IP reputation.<\/li>\n\n\n\n<li><b>Your domain reputation is based on the domain from which you send mail, like mailgun.com. <\/b>Much like your IP reputation, your domain reputation is determined by the email you send from the domain.<\/li>\n<\/ul>\n\n<p class=\"wp-block-paragraph\">Let\u2019s unpack this for clarity. Here are some components that determine your IP and domain reputation, which, in turn, determine your sender reputation:<\/p>\n\n<ul class=\"wp-block-list\">\n<li><b>Email content: <\/b>Are you sending high-quality emails that your subscribers want to receive? Email content that contains spammy characteristics or wording is flagged as low-quality emails. All-image emails and messages that are too large in size may also look like red flags to ISPs. You don\u2019t want mailbox providers to think you\u2019re a spammer.<\/li>\n\n\n\n<li><b>Abuse complaints:<\/b> When subscribers mark your emails as spam, it\u2019s recorded as a spam complaint \u2013 also known as an abuse complaint. A high complaint rate might trigger spam filters and negatively impact your sender reputation. To avoid receiving abuse complaints, make it easy for your readers to unsubscribe when they no longer want to receive your messages.<\/li>\n\n\n\n<li><b>Email list quality: <\/b>Your reputation goes beyond your email content itself. For example, if you don\u2019t maintain your mailing list through regular email verifications, you risk having spam traps or invalid email addresses as part of your list. This results in a high bounce rate, which sends a red flag to mailbox providers because it appears like your content isn\u2019t welcome.<\/li>\n\n\n\n<li><b>Sending history: <\/b>Okay, this one is a bit of a chicken-and-egg problem. If your IP address does not have a history of <a href=\"https:\/\/www.mailgun.com\/es\/productos\/send\/\" target=\"_tabs\" rel=\"noopener noreferrer\">sending mail consistently<\/a>, you\u2019ll need to \u201cwarm up\u201d your IP and build trust before you start sending email marketing campaigns at scale. Also, if you have a spotty sending history, you\u2019ll be flagged as a potentially problematic sender. This, in turn, will cause problems for your email sending.<\/li>\n<\/ul>\n\n<h2 class=\"wp-block-heading\">What are the consequences of being a bad sender?<\/h2>\n\n<p class=\"wp-block-paragraph\">So you\u2019ve integrated your app with an email service provider (ESP). That\u2019s it, right? Not quite.<\/p>\n\n<p class=\"wp-block-paragraph\">If you\u2019re using an EPS like Mailgun, we\u2019ll help you protect your sender reputation. However, not all ESPs are created equal, and you may be on the hook for looking after your own sender reputation. If you have a bad sender reputation, ISPs will flag your messages and will be less likely to place your emails in your reader\u2019s inbox.<\/p>\n\n<p class=\"wp-block-paragraph\">Make sure your great email campaign reaches your reader\u2019s inbox. Maintain a good sender reputation to ensure your email deliverability.<\/p>\n\r\n    <aside data-content-type=\"longform\"  class=\"banner-block longform-spacings rounded-lg shadow-lg px-5 py-6 px-md-6 py-md-7 p-lg-7 bg-light\" data-theme=\"light\" aria-labelledby=\"banner-block-block_cf84f38ba47ec5ff33dcf64a2b2f2687\">\r\n                            <p class=\"h4 text-accent fw-bold\" id=\"banner-block-block_cf84f38ba47ec5ff33dcf64a2b2f2687\">\r\n                Be a better communicator             <\/p>\r\n                            <div class=\"mb-0 text-body-color\">\r\n                                    <div class=\"content-body mb-0 text-body-color\"><p class=\"mb-0\">Take on communication challenges in 2025 with insights from the Sinch state of customer communications report.&nbsp;<\/p><\/div>\r\n                            <\/div>\r\n        \r\n        <div class=\"text-start mt-5\"><a href=\"https:\/\/sinch.com\/state-of-customer-communications\/chapter\/industry-insights\/\" target=\"_blank\" class=\"btn btn-secondary\" >Read the Report<\/a><\/div>\r\n    <\/aside>\r\n\r\n\n<h2 class=\"wp-block-heading\">5 ways to improve your sender reputation<\/h2>\n\n<p class=\"wp-block-paragraph\">While you can use tools like Sender Score to monitor your reputation score, that\u2019s not enough by itself. Instead, check out these tips to improve your sender reputation:<\/p>\n\n<ol class=\"wp-block-list\">\n<li>Maintain mailing list hygiene.<\/li>\n\n\n\n<li>Provide an easy way to unsubscribe.<\/li>\n\n\n\n<li>Use double opt-ins.<\/li>\n\n\n\n<li>Check if you\u2019ve been blocklisted.<\/li>\n\n\n\n<li>Have proper authentication protocols in place.<\/li>\n<\/ol>\n\n<p class=\"wp-block-paragraph\">Let\u2019s go over each of these below.<\/p>\n\n<h3 class=\"wp-block-heading\">1. Maintain mailing list hygiene<\/h3>\n\n<p class=\"wp-block-paragraph\"><a href=\"\/products\/inbox\/email-verification\/\" target=\"_tabs\" rel=\"noopener noreferrer\">Verify your email list <\/a>regularly to purge invalid addresses, spam traps, and disengaged subscribers. This lowers your bounce rate and increases your open rate. Both of these metrics will help improve your sender reputation. In fact, as Nick Schafer of Sinch Mailgun explains in this video, he believes that these are some of the most important metrics if you want to improve your sender reputation.<\/p>\n\t<div class=\"custom-video\">\r\n\t\t\t\t\t                    <div class=\"iframe-responsive-container lazy-video rounded-lg overflow-hidden \">\r\n                <a href=\"https:\/\/www.youtube.com\/watch?v=7sQiYfxxEsQ\" class=\"lazy-video-link\" data-lazy-video=\"7sQiYfxxEsQ\" target=\"_blank\" rel=\"nofollow\" role=\"button\" data-source=\"youtube\" data-language=\"es\" data-thumb=\"https:\/\/img.youtube.com\/vi\/7sQiYfxxEsQ\/maxresdefault.jpg\" title=\"V\u00eddeo de Sinch\">\r\n                    <div class=\"btn btn-light btn-light-social btn-play btn-play-circle\">\r\n                                                    <svg aria-hidden=\"true\" data-url=\"https:\/\/www.mailgun.com\/wp-content\/plugins\/sinch-core\/assets\/icons\/sinch\/play.svg\"><\/svg>\r\n                                            <\/div>\r\n                    <img decoding=\"async\"  src=\"https:\/\/img.youtube.com\/vi\/7sQiYfxxEsQ\/maxresdefault.jpg\" alt=\"Need to improve sender reputation?

Are they positive or negative? Services like Gmail, Yahoo Mail, Outlook, and others are paying attention to how your contacts respond to your campaigns and messages. If it seems like your subscribers don\\u2019t care about what you\\u2019re sending, your ability to reach the inbox could suffer. \\n\\nIn this video, Nick Schafer of Sinch Mailgun explains how much email engagement impacts deliverability and sender reputation. If you want to get delivered to more inboxes, you\\u2019d better make sure that recipients find your emails engaging enough to open and click. \\n\\nThe same goes for senders who are trying to improve damaged sender reputation. The best way to prove your emails deserve to be in the inbox is to show positive engagement signals. Mailbox providers are not only trying to protect their users from bad actors, but they also want to provide an ideal inbox experience. Good engagement rates tell them emails from your business deserve inbox placement. \\n\\nLearn about other factors that can help improve sender reputation in a free report from Sinch Mailgun: \\nhttps:\/\/www.mailgun.com\/resources\/research\/email-sender-reputation\/ \\n\\nGet advice on how to improve sender reputation in this article: \\nhttps:\/\/www.mailgun.com\/blog\/deliverability\/improve-sender-reputation\/\",\n    \"uploadDate\": \"2024-12-10T21:59:40+00:00\",\n    \"duration\": \"PT1M29S\"\n}        <\/script>\r\n        \t\t\r\n\t\t\t<\/div>\r\n\r\n\t\r\n\n<h3 class=\"wp-block-heading\">2. Provide an easy way to unsubscribe<\/h3>\n\n<p class=\"wp-block-paragraph\">Avoid abuse complaints by giving your readers an easy way to unsubscribe when they want to opt out of their relationship with you. It\u2019s sad to see them go, but that\u2019s better than waiting for them to mark your messages as spam.<\/p>\n\n<h3 class=\"wp-block-heading\">3. Use double opt-ins<\/h3>\n\n<p class=\"wp-block-paragraph\">Asking your subscribers to verify their emails before adding them to your mailing list might seem like an unnecessary extra hoop to jump through. However, this extra step helps to verify that the email addresses on your mailing list are valid. More importantly, you give your users a chance to confirm that they actually want to receive your messages.<\/p>\n\n<h3 class=\"wp-block-heading\">4. Check if you\u2019ve been blocklisted<\/h3>\n\n<p class=\"wp-block-paragraph\">Even if you\u2019re a legitimate sender mailing high-quality content, you might <a href=\"https:\/\/www.mailgun.com\/es\/blog\/deliverability\/como-eliminar-ip-dominio-lista-bloqueo-email\/\" target=\"_tabs\" rel=\"noopener noreferrer\">end up on a blocklist<\/a>. Check if you\u2019re on a blocklist before sending out your next email campaign to ensure your messages land in your reader\u2019s inbox. After all, if you\u2019re on a blocklist, your messages will never make it to your reader\u2019s inbox. A high bounce rate can negatively affect your sending reputation. At Mailgun, we provide a <a href=\"https:\/\/www.mailgun.com\/es\/products\/inbox\/deliverability\/blocklist-monitoring-service\/\" target=\"_tabs\" rel=\"noopener noreferrer\">blocklist monitoring service<\/a> to keep your deliverability rates high.<\/p>\n\n<h3 class=\"wp-block-heading\">5. Have proper authentication protocols in place<\/h3>\n\n<p class=\"wp-block-paragraph\">Before you start sending, make sure you have your <a href=\"https:\/\/www.mailgun.com\/es\/blog\/deliverability\/autenticacion-emails-documento-identidad-envios\/\" target=\"_tabs\" rel=\"noopener noreferrer\">SPF, DKIM, DMARC, and BIMI<\/a> records in place. These authentication protocols are your ID cards that prove you are who you say you are. Think of mailbox providers as the bouncers in a club. Your authentication records ensure you can join the party and stick that landing in your user\u2019s inbox.<\/p>\n\n<h2 class=\"wp-block-heading\">Wrapping up<\/h2>\n\n<p class=\"wp-block-paragraph\">And that\u2019s sender reputation in a nutshell. It\u2019s not just about technology \u2013 it\u2019s about behavior, consistency, and respect for your audience. If you over-send, ignore list hygiene, or skip best practices, you risk coming off like that person who just doesn\u2019t get the hint.<\/p>\n\n<p class=\"wp-block-paragraph\">As Natalie Hays, Senior Product Marketing Manager at Sinch Mailgun, explained in <a href=\"https:\/\/www.mailgun.com\/blog\/email\/deliverability-academy-episode-two-recap\/\" target=\"_tabs\" rel=\"noopener noreferrer\">episode two of our Deliverability Academy webinar<\/a>:<\/p>\n    <div data-content-type=\"longform\" class=\"quote hub-quote longform-spacings d-flex flex-column rounded-lg px-5 py-6 px-md-6 py-md-7 p-lg-7 shadow-sm bg-primary\" data-theme=\"light\">\r\n\r\n        <div class=\"quote-logo mb-3\">\r\n                            <svg height=\"40\" class=\"quote-icon quote-icon-color\" aria-hidden=\"true\" data-url=\"https:\/\/www.mailgun.com\/wp-content\/plugins\/sinch-core\/assets\/icons\/custom-icons\/quotes-right.svg\"><\/svg>\r\n                    <\/div>\r\n\r\n        <blockquote class=\"quote-content content-body m-0 text-body-color\" id=\"quote-block-6c9db2d402421d83b877d36a00134ac1\">\r\n            Imagine you meet someone new, and you want to be friends.

This type of behavior is seen as \u201cspammy\u201d and can negatively impact your sender reputation. Instead, slowly warm up your IP for sending at volume. Some ESPs, like Mailgun, warm up your dedicated IP address as a service.<\/p>\n\n<h3 class=\"wp-block-heading\">What happens if I send out spammy-looking content?<\/h3>\n\n<p class=\"wp-block-paragraph\">This goes without saying, but if it looks like spam, chances are that ISPs will treat it as spam. Don\u2019t use all-image emails, spammy words, too many exclamation points, or too many emojis. Check your subject lines for spelling mistakes! If your message looks like spam, ISPs could refuse to place it in your reader\u2019s inbox. This will negatively impact your reputation.<\/p>\n\n<h3 class=\"wp-block-heading\">What if I forget to remove disengaged users?<\/h3>\n\n<p class=\"wp-block-paragraph\">Keep tabs on your email marketing metrics \u2013 like open rate, click-through rate, and conversion rate \u2013 to determine if your readers are still engaged. If your readers have become disengaged, you can send a re-engagement email or create a sunset policy to <a href=\"https:\/\/www.mailgun.com\/es\/blog\/deliverability\/politicas-sunset-contactos-sin-interaccion\/\" target=\"_tabs\" rel=\"noopener noreferrer\">remove them<\/a> from your email list.<\/p>\n\n<h3 class=\"wp-block-heading\">Can I use a shared IP address?<\/h3>\n\n<p class=\"wp-block-paragraph\">As we mentioned above, using a shared IP means sharing your IP reputation with other senders. Of course, this can be a good thing if you\u2019re a new sender and want to piggyback off of an IP with an established reputation. However, this can backfire if the other senders on your IP have bad email sending habits.
