They scan each email for suspicious signals and assign a \u201cspam score.\u201d If this score is too high, the message is marked as spam or rejected altogether.<\/p>\n<p>Spam filters use various criteria to analyze incoming messages \u2014 from technical setup and sender reputation to content, formatting, and even recipient engagement. So, let\u2019s break down what factors can affect your deliverability and possible reasons why your emails are going to spam.<\/p>\n<h3>1. You haven\u2019t set up SPF, DKIM, or DMARC records<\/h3>\n<p>When DNS (Domain Name System) records, such as SPF, DKIM, and DMARC, are not set up, providers can\u2019t verify that you\u2019re a legitimate sender. This directly influences your sender reputation and makes your emails look suspicious or spoofed. As a result, they can get flagged or blocked by spam filters.<\/p>\n<div class=\"content-banner default\">\n<p class=\"content-banner__title\">Check your SPF, DKIM, and DMARC records in seconds<\/p>\n<p class=\"content-banner__description\">Run Snov.io Deliverability Test<\/p>\n<div class=\"content-banner__link\"><a href=\"https:\/\/app.snov.io\/register?lang=en&amp;signup_source=blog&amp;signup_page=snov.io%2Fblog%2Fsales-email-templates&amp;cta_type=banner\">Try now<\/a><\/div>\n<div class=\"content-banner__img\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/snov.io\/blog\/wp-content\/uploads\/2024\/08\/Icon-3-opt-7.png\" alt=\"Check your SPF DKIM, and DMARC records in seconds\" width=\"224\" height=\"224\" \/><\/div>\n<\/div>\n<h3>2. You\u2019ve got a low sender reputation<\/h3>\n<p>ESPs track your domain\u2019s behavior, analyzing bounces, complaints, and engagement level. If many people ignore your messages or rarely interact with them, it may negatively impact your reputation. With a low sender score, it becomes more likely that your emails go to the spam folder.<\/p>\n<h3>3. Your sending IP isn\u2019t trustworthy<\/h3>\n<p>This issue may happen when you use a shared email address. The thing is that ESPs associate harmful activity not only with the domain, but also with the mailing IP. If others on the same IP address send spammy content, your deliverability will also suffer.<\/p>\n<p>What\u2019s more, the IP\u2019s reputation stays with the address for months, so its history also matters. Even though you\u2019re doing everything right, negative reputation history records on your shared IP may be another reason why your emails are going to spam.<\/p>\n<h3>4. Your email list quality is poor<\/h3>\n<p>When I hear \u201cWhy are my emails going to spam?\u201d, I usually ask, \u201cHow often do you clean your list?\u201d If you do it approximately never, this explains a lot. Outdated, bought, or scrapped lists (especially when you\u2019re using unreliable scraping tools) often contain invalid addresses.<\/p>\n<p>Sending to unengaged or non-existent contacts commonly results in high bounce rates and low interaction. This may signal ESPs that your content is unwanted and make your emails go to spam.<\/p>\n<div class='posts-into__content'>\r\n<div class=\"post\">\r\n    <div class=\"post__img\">\r\n        <img loading=\"lazy\" decoding=\"async\" width=\"320\" height=\"160\" src=\"https:\/\/snov.io\/blog\/wp-content\/uploads\/2024\/02\/Build-email-list.png\" class=\"attachment-327x160 size-327x160 wp-post-image\" alt=\"Mailing list: qu\u00e9 es, c\u00f3mo crearla y por qu\u00e9 es importante\" srcset=\"https:\/\/snov.io\/blog\/wp-content\/uploads\/2024\/02\/Build-email-list.png 2250w, https:\/\/snov.io\/blog\/wp-content\/uploads\/2024\/02\/Build-email-list-300x150.png 300w, https:\/\/snov.io\/blog\/wp-content\/uploads\/2024\/02\/Build-email-list-1024x512.png 1024w, https:\/\/snov.io\/blog\/wp-content\/uploads\/2024\/02\/Build-email-list-768x384.png 768w, https:\/\/snov.io\/blog\/wp-content\/uploads\/2024\/02\/Build-email-list-1536x768.png 1536w, https:\/\/snov.io\/blog\/wp-content\/uploads\/2024\/02\/Build-email-list-2048x1024.png 2048w\" sizes=\"(max-width: 320px) 100vw, 320px\" \/>    <\/div>\r\n    <div class=\"post__content\">\r\n        <p class=\"post__content-title\">\r\n            <a href=\"https:\/\/snov.io\/blog\/how-to-build-an-email-list\/\">How To Build An Email List: Best Strategies &#038; Tools For Successful Email Marketing<\/a>\r\n        <\/p>\r\n        <p class=\"post__content-date\">17\/03\/2026<\/p>    <\/div>\r\n<\/div>\r\n<div class=\"post\">\r\n    <div class=\"post__img\">\r\n        <img loading=\"lazy\" decoding=\"async\" width=\"320\" height=\"160\" src=\"https:\/\/snov.io\/blog\/wp-content\/uploads\/2023\/02\/1-1.png\" class=\"attachment-327x160 size-327x160 wp-post-image\" alt=\"Email Hygiene Is Easy: 8 Best Email List Cleaning Practices\" srcset=\"https:\/\/snov.io\/blog\/wp-content\/uploads\/2023\/02\/1-1.png 1500w, https:\/\/snov.io\/blog\/wp-content\/uploads\/2023\/02\/1-1-300x150.png 300w, https:\/\/snov.io\/blog\/wp-content\/uploads\/2023\/02\/1-1-1024x512.png 1024w, https:\/\/snov.io\/blog\/wp-content\/uploads\/2023\/02\/1-1-768x384.png 768w\" sizes=\"(max-width: 320px) 100vw, 320px\" \/>    <\/div>\r\n    <div class=\"post__content\">\r\n        <p class=\"post__content-title\">\r\n            <a href=\"https:\/\/snov.io\/blog\/email-list-cleaning\/\">Email Hygiene Is Easy: 8 Best Email List Cleaning Practices<\/a>\r\n        <\/p>\r\n        <p class=\"post__content-date\">9\/04\/2026<\/p>    <\/div>\r\n<\/div><\/div>\n<h3>5. Recipients marked your emails as spam<\/h3>\n<p>I know it hurts, but sometimes recipients themselves flag messages as spam. These feedbacks go directly to providers, increasing your spam complaint rate. So, even a few manually marked emails can seriously damage a sender reputation, especially when sending to irrelevant contacts.<\/p>\n<h3>6. Your sending behavior looks suspicious<\/h3>\n<p>If you start sending hundreds of messages at once without doing a proper warm-up, you\u2019ll look suspicious to ESPs. It is especially risky when your account is new or has been inactive for a while. Sudden spikes in volume or inconsistent activity resemble spam-like behavior, preventing campaigns from landing in users\u2019 inboxes.<\/p>\n<h3>7. You don\u2019t provide the \u201cUnsubscribe\u201d option<\/h3>\n<p>Failing to include an unsubscribe link in emails violates spam regulations, such as CAN-SPAM and <a href=\"https:\/\/snov.io\/knowledgebase\/is-snov-io-compliant-with-the-gdpr\/\">GDPR<\/a>. So, filters detect this behavior as deceptive or aggressive, flagging your messages as spam.<\/p>\n<h3>8. You include too many images, links, and attachments<\/h3>\n<p>Adding too many visuals, links, or heavy attachments may also be a reason why your email goes to spam. The thing is that spam filters can\u2019t read images like they do text, so image-only messages are considered suspicious.<\/p>\n<p>As for cold emailing, including images even alongside the text can trigger spam filters. For example, Gmail often displays a warning when it detects content from unfamiliar senders. Thus, your images aren\u2019t shown by default, and recipients are asked whether they want to see them.<\/p>\n<p>Meanwhile, large files with many links in messages may also be blocked as they often resemble promotional spam content or phishing attempts.<\/p>\n<h3>9. You\u2019re using spam trigger words<\/h3>\n<p>The words and phrases, like \u201cfree,\u201d \u201cbuy now,\u201d \u201cact now,\u201d \u201ccash,\u201d \u201ccredit,\u201d and so on, especially when combined with excessive punctuation or capitalization, can cause serious spam issues. This wording is typically used in scams, so filters treat it with caution. And let\u2019s be honest, using these phrases makes a message look unprofessional.<\/p>\n<h2 id=\"how\">How to avoid the spam folder and enhance email deliverability<\/h2>\n<p>Now that you know the main issues that can affect deliverability, consider practical strategies and tips on how to avoid the spam folder:<\/p>\n<h3>Set up proper authentication<\/h3>\n<p>To establish trust with inbox providers, complete a domain&#8217;s DNS setup before sending campaigns. If your email fails the authentication check, it\u2019s a signal that it may be blocked by spam filters.<\/p>\n<p>Configure SPF, DKIM, and DMARC settings to prove that your messages come from an authorized sender. These protocols help prevent spoofing and phishing, making your domain more trustworthy in the eyes of inbox providers:<\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>SPF (Sender Policy Framework)<\/b> contains information about IP addresses allowed to send campaigns from a specific domain.<\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>DKIM (DomainKeys Identified Mail)<\/b> adds a digital signature to your messages, verifying that the email content hasn\u2019t been changed during transit.<\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>DMARC<\/b> sets rules for how ESPs should process incoming emails that fail SPF or DKIM checks.<\/li>\n<\/ul>\n<p><b>\u2192 Learn <\/b>how to avoid the spam folder by <a href=\"https:\/\/snov.io\/knowledgebase\/how-to-setup-dns-records-spf-dkim-dmarc-and-mx\/\"><b>setting up DNS records<\/b><\/a><b> for a sender domain.<\/b><\/p>\n<h3>Build a targeted email address list<\/h3>\n<p>Ensure your list consists of recipients who truly match your target audience and actually want to hear from you.

Make your message clear, personalized, and relevant to your audience. Recipients should clearly understand the value you offer from the start. Consider creating a professional subject line that accurately reflects the content of the message and resonates with the recipient.<\/p>\n<p>Avoid spam-trigger phrases, excessive punctuation or capitalization, and bold fonts. Don\u2019t tease spam filters with excessive images, links, or heavy attachments. One visual or link is more than enough.<\/p>\n<p><b>\ud83d\udca1 Expert tip<\/b><\/p>\n<p><span style=\"font-weight: 400;\">I recommend including a plain-text version if you\u2019re using HTML. Thus, you\u2019ll build trust with <\/span><span style=\"font-weight: 400;\">spam filters<\/span><span style=\"font-weight: 400;\"> by showing that you\u2019re a legitimate sender who follows best practices.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">It also ensures your emails are visible to recipients who don\u2019t view HTML content in their inbox. Finally, this approach may yield higher open and reply rates, as screen readers often rely on the plain-text format for scanning messages.<\/span><\/p>\n<h3>Get a dedicated IP address<\/h3>\n<p>With a dedicated IP, you\u2019ll have full control of your sender reputation, receiving a personal email server\u2019s address you won\u2019t share with anyone else.<\/p>\n<p>The ESPs, such as Microsoft (Outlook), Zoho, Sengrid, Mailgun, and others, provide dedicated IP addresses. However, in many cases, this option is available only if you\u2019re consistently sending in high volumes. If your volume is low, consider warming up your account gradually.<\/p>\n<p><b>\u2192 Learn more about how you can set up a <\/b><a href=\"https:\/\/snov.io\/knowledgebase\/how-to-set-up-a-dedicated-ip-address-for-sending-emails\/?utm_source=chatgpt.com\"><b>dedicated IP address<\/b><\/a><b>.<\/b><\/p>\n<h3>Use clear \u201cFrom\u201d information<\/h3>\n<p>A key but often overlooked strategy on how to avoid the spam folder involves ensuring a clear sender name. If your \u201cFrom\u201d section looks vague, unfamiliar to recipients, or suspicious, users might mark your message as spam. Or else, it may trigger spam filters, bringing you the same outcome.<\/p>\n<p>Always use a recognizable name to build trust with both recipients and email service providers. You can include your full name and brand name in the \u201cFrom\u201d field. Just ensure consistency, so the sending address matches the domain.<\/p>\n<h3>Follow reasonable sending limits<\/h3>\n<p>Whether the idea of reaching out to many prospects at once sounds tempting, it\u2019s better to avoid sending large volumes too quickly. Instead, increase the daily limit gradually. Our experts recommend keeping a sending capacity of <b>50-100 emails per day<\/b> from a single account.<\/p>\n<p>Sending more than this limit can be considered spamming activity by inbox providers. If you need to send emails in large volumes, consider distributing them across multiple accounts.<\/p>\n<p>Besides, if your opens or replies are not as high as you expect, don\u2019t try to compensate for it by increasing the number of recipients. In the end, no matter how many messages you send, if your email goes to spam. Instead, refine your email content, implement targeted <a href=\"https:\/\/snov.io\/blog\/email-segmentation\/\">segmentation strategies<\/a>, and conduct A\/B testing to find out what resonates most with your audience.<\/p>\n<blockquote class=\"blockquote-with__image\"><p>A\/B testing plays a critical role in optimizing cold outreach. Sometimes, something as small as having (or not having) a dot at the end of the subject line can impact reply rates. Even using an exclamation mark (!) can influence how your message is perceived.<\/p>\n<p>&nbsp;<\/p>\n<p>To ensure accurate results, test only one thing at a time and with similar ICPs. Thus, you can get what actually changed. A\/B tests for whole emails are not actually A\/B tests.<\/p>\n<div class=\"blockquote-image\">\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/snov.io\/blog\/wp-content\/uploads\/2025\/07\/maia.jpeg\" alt=\"Atahualpa Maia\" width=\"48\" height=\"48\" \/><\/p>\n<div class=\"blockquote-image__info\">\n<p class=\"blockquote-image__info-author\">Atahualpa Maia<\/p>\n<p class=\"blockquote-image__info-position\">VP of Sales at Snov.io<\/p>\n<\/div>\n<\/div>\n<\/blockquote>\n<h2 id=\"how2\">How Snov.io helps you stay out of spam<\/h2>\n<p>One of the most often-overlooked secrets of how to avoid the spam folder is a reliable outreach tool.
