Every email service &ndash; including the one you use and the one your recipient uses &ndash; performs these checks to ensure that the message is not harmful and can be <b>safely delivered<\/b>. <\/p><p class=\"no-margin\">\n<\/p><p class=\"no-margin\">When your messages do not meet your reputation parameters, you may encounter <b>delays or delivery issues<\/b>, such as emails ending up in the receiver&rsquo;s <a href=\"\/support\/3423286-what-to-do-if-your-emails-go-to-spam\" target=\"_blank\" class=\"intercom-content-link\">spam folder<\/a>. To fix it, you can apply measures that will <b>improve your domain&rsquo;s email reputation<\/b> by following these steps &#128071; <\/p><p class=\"no-margin\">\n<\/p><h2 id=\"h_b4f7e7c393\">Step 1 &ndash; Add email DNS records<\/h2><p class=\"no-margin\">Aside from the <b>MX records<\/b>, which are an absolute must for emails to work, two additional types of records are essential for email deliverability &ndash; <b>SPF<\/b> and <b>DKIM<\/b> records:<\/p><ol>\n<li>\n<p class=\"no-margin\"><b>SPF<\/b> (stands for <b>Sender Policy Framework<\/b>) record allows domain owners to specify which email servers are authorized to send emails on their behalf.<\/p>\n<\/li>\n<li>\n<p class=\"no-margin\"><b>DKIM<\/b> (stands for <b>DomainKeys Identified Mail<\/b>) record is used for signing and verifying the authenticity of emails: it involves adding a digital signature to outgoing emails that the recipient&rsquo;s email server can verify.<\/p>\n<\/li>\n<\/ol><p class=\"no-margin\">\n<\/p><h2 id=\"h_472762ca21\">Step 2 &ndash; Improve the email subject<\/h2><p class=\"no-margin\">One of the most important factors affecting email deliverability is the <b>subject line <\/b>of your messages. Make sure to compose subjects that are <b>relevant <\/b>to your audience and<b> related to the message content<\/b>. <\/p><p class=\"no-margin\">\n<\/p><p class=\"no-margin\">In addition, you should <b>avoid<\/b> the following:<\/p><ul>\n<li>\n<p class=\"no-margin\"><b>Misspelled <\/b>words.<\/p>\n<\/li>\n<li>\n<p class=\"no-margin\">Using ALL CAPITAL LETTERS.<\/p>\n<\/li>\n<li>\n<p class=\"no-margin\">The words &ldquo;<b>Test<\/b>&ldquo;, &ldquo;<b>Check<\/b>&ldquo;, or similar.<\/p>\n<\/li>\n<li>\n<p class=\"no-margin\">Phrases like &ldquo;<b>Open this<\/b>&ldquo;, &ldquo;<b>Read me<\/b>&ldquo;, &ldquo;<b>Urgent<\/b>&ldquo;, or similar.<\/p>\n<\/li>\n<li>\n<p class=\"no-margin\"><b>Random<\/b> letters or numbers, as well as using any <b>special characters<\/b> (like %^&gt;).<\/p>\n<\/li>\n<\/ul><p class=\"no-margin\">More recommendations:<\/p><ul>\n<li>\n<p class=\"no-margin\">Aim for shorter subject lines, though use more than <b>one word<\/b>; e.g., avoid writing only &ldquo;Hello&rdquo;.<\/p>\n<\/li>\n<li>\n<p class=\"no-margin\"><b>Don&rsquo;t leave the subject blank<\/b>.<\/p>\n<\/li>\n<li>\n<p class=\"no-margin\">Remove the &ldquo;<b>Re<\/b>:&rdquo; from message replies.<\/p>\n<\/li>\n<\/ul><p class=\"no-margin\">This way, your subject line will be more positively accepted by both the mail services and your recipients.<\/p><p class=\"no-margin\">\n<\/p><h2 id=\"h_ff0d29aa15\">Step 3 &ndash; Review your contact list<\/h2><p class=\"no-margin\">When it comes to <b>engaging email recipients<\/b>, make sure to send messages only to users who have <b>opted in<\/b> to receive your emails. Sending emails without recipient permission can result in high rates of unsubscribes and spam reports.<\/p><p class=\"no-margin\">\n<\/p><p class=\"no-margin\">In addition, regularly check your email list for <b>nonexistent or invalid<\/b> email addresses. Sending emails to these addresses can also impact your email reputation and lower deliverability rates.<\/p><p class=\"no-margin\">\n<\/p><p class=\"no-margin\">Regarding the <b>volume of messages sent<\/b>, make sure to stay within your account&rsquo;s limits and <b>avoid<\/b> <a href=\"\/support\/1583510-can-i-send-mass-mail\" target=\"_blank\" class=\"intercom-content-link\">mass mailing<\/a>. If you want to conduct an email campaign, consider a <b>dedicated solution<\/b>, as they specialize in handling high email volume while also providing greater tools, features, and analytics.<\/p><p class=\"no-margin\">\n<\/p><h2 id=\"h_8398f46ca3\">Step 4 &ndash; Test your messages<\/h2><p class=\"no-margin\">Once you have applied the previous steps, you can check your emails against several reputation algorithms with one single tool. All you will need to do is:<\/p><ol>\n<li>\n<p class=\"no-margin\">Go to <a href=\"https:\/\/www.mail-tester.com\/\" target=\"_blank\" class=\"intercom-content-link\" rel=\"noopener\">Mail-Tester<\/a><b> <\/b>and obtain the recipient testing address.<\/p>\n<\/li>\n<li>\n<p class=\"no-margin\"><b>Send <\/b>a message from your email account to the test address using the same subject and content that you would send to any of your usual recipients.<\/p>\n<\/li>\n<li>\n<p class=\"no-margin\">Go back to the Mail Tester page and click on <b>Check your score<\/b>.<\/p>\n<\/li>\n<li>\n<p class=\"no-margin\"><b>Scroll down<\/b> the score page and expand each section to find specific recommendations to improve deliverability.<\/p>\n<\/li>\n<\/ol><p class=\"no-margin\">That&rsquo;s it! After completing the above steps, your emails should properly reach your recipients.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>How to ensure that your emails are delivered to the receiver<\/p>\n","protected":false},"author":581,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"include_on_kodee":true,"footnotes":""},"categories":[288],"tags":[],"class_list":["post-1075","post","type-post","status-publish","format-standard","hentry","category-hostinger-email-getting-started"],"hreflangs":[{"locale":"en-US","link":"https:\/\/www.hostinger.com\/support\/5240869-improve-email-deliverability-at-hostinger\/","default":1},{"locale":"es-ES","link":"https:\/\/www.hostinger.com\/es\/support\/5240869-como-mejorar-la-entrega-de-tus-emails-en-hostinger\/","default":0},{"locale":"fr-FR","link":"https:\/\/www.hostinger.com\/fr\/support\/5240869-comment-ameliorer-la-delivrabilite-des-e-mails-chez-hostinger\/","default":0},{"locale":"id-ID","link":"https:\/\/www.hostinger.com\/id\/support\/5240869-bagaimana-cara-meningkatkan-pengiriman-email-di-hostinger\/","default":0},{"locale":"lt-LT","link":"https:\/\/www.hostinger.com\/lt\/support\/5240869-kaip-pagerinti-el-laisku-pristatyma-hostinger-platformoje\/","default":0},{"locale":"pt-PT","link":"https:\/\/www.hostinger.com\/br\/support\/5240869-como-melhorar-a-entrega-de-e-mail-na-hostinger\/","default":0},{"locale":"uk-UA","link":"https:\/\/www.hostinger.com\/ua\/support\/5240869---\/","default":0}],"include_on_kodee":true,"_links":{"self":[{"href":"https:\/\/www.hostinger.com\/support\/wp-json\/wp\/v2\/posts\/1075","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.hostinger.com\/support\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.hostinger.com\/support\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.hostinger.com\/support\/wp-json\/wp\/v2\/users\/581"}],"replies":[{"embeddable":true,"href":"https:\/\/www.hostinger.com\/support\/wp-json\/wp\/v2\/comments?post=1075"}],"version-history":[{"count":0,"href":"https:\/\/www.hostinger.com\/support\/wp-json\/wp\/v2\/posts\/1075\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.hostinger.com\/support\/wp-json\/wp\/v2\/media?parent=1075"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.hostinger.com\/support\/wp-json\/wp\/v2\/categories?post=1075"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.hostinger.com\/support\/wp-json\/wp\/v2\/tags?post=1075"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
