Checking <a href=\"https:\/\/emailwarmup.com\/blog\/email-deliverability\/what-is-email-deliverability\/\" target=\"_blank\" rel=\"noreferrer noopener\">email deliverability<\/a> shows you the difference between <em>reaching a server<\/em> and <em>reaching the inbox<\/em>.<\/p>\n\n\n\n<p>At a quick glance, you must know that:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Deliverability testing sends emails to controlled mailboxes across providers<\/li>\n\n\n\n<li>Results show exact placement percentages (inbox, promotions, spam, unreceived)<\/li>\n\n\n\n<li>Provider-specific breakdowns reveal where you&#8217;re passing and failing<\/li>\n\n\n\n<li>Checking before campaigns catches problems that tank open rates<\/li>\n<\/ul>\n\n\n\n<p>This guide covers the available checking methods, how to run a test, and what the results mean for your sending.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why should you check email deliverability before sending campaigns?<\/h2>\n\n\n\n<p>Send reports only, confirm your email left the server \u2014 not that anyone will see it.<\/p>\n\n\n\n<p>The gap between delivery and deliverability costs campaigns without warning. An email marked &#8220;delivered&#8221; might land in:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Spam folder \u2014 never seen<\/li>\n\n\n\n<li>Primary inbox \u2014 visible immediately<\/li>\n\n\n\n<li>Blocked entirely \u2014 rejected before arrival<\/li>\n\n\n\n<li>Promotions tab \u2014 checked weekly at best<\/li>\n<\/ul>\n\n\n\n<p>Testing reveals this reality before you burn through prospect lists. A cold email campaign sent to 10,000 contacts with 50% inbox placement means 5,000 people never had a chance to respond (and you won&#8217;t know from open rates alone \u2014 <a href=\"https:\/\/emailwarmup.com\/blog\/emails-going-to-spam\/email-spam-filtering\/\" target=\"_blank\" rel=\"noreferrer noopener\">email spam filtering<\/a> happens silently).<\/p>\n\n\n\n<p>The damage <strong>compounds<\/strong>. Poor placement signals trigger stricter filtering on future sends. One bad campaign can shift your domain from &#8220;trusted sender&#8221; to &#8220;suspicious&#8221; across Gmail, Outlook, and Yahoo simultaneously.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What does a deliverability test actually measure?<\/h2>\n\n\n\n<p>A deliverability test sends your email to seed mailboxes across multiple providers, then checks where each copy landed.<\/p>\n\n\n\n<p>The core metrics break down like this:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td>Metric<\/td><td>What it measures<\/td><td>Why it matters<\/td><\/tr><tr><td>Inbox rate<\/td><td>% reaching primary inbox<\/td><td>Your actual visibility to recipients<\/td><\/tr><tr><td>Promotions rate<\/td><td>% sorted to promotions\/updates tab<\/td><td>Reduces open rates by 40-60%<\/td><\/tr><tr><td>Spam rate<\/td><td>% filtered as spam<\/td><td>Recipients never see these<\/td><\/tr><tr><td>Unreceived rate<\/td><td>% blocked before delivery<\/td><td>Often indicates blocklisting<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p>Beyond placement percentages, comprehensive tests also check:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Provider variance \u2014 how Gmail treats you versus Outlook<\/li>\n\n\n\n<li>Domain reputation \u2014 blocklist presence, domain age signals<\/li>\n\n\n\n<li>Content flags \u2014 spam trigger words, broken links, image ratios<\/li>\n\n\n\n<li>Authentication status \u2014 <a href=\"https:\/\/emailwarmup.com\/spf-lookup\" target=\"_blank\" rel=\"noreferrer noopener\">SPF lookup<\/a>, <a href=\"https:\/\/emailwarmup.com\/dkim-lookup\" target=\"_blank\" rel=\"noreferrer noopener\">DKIM lookup<\/a>, <a href=\"https:\/\/emailwarmup.com\/dmarc-lookup\" target=\"_blank\" rel=\"noreferrer noopener\">DMARC lookup<\/a> per provider<\/li>\n<\/ul>\n\n\n\n<p>The provider breakdown matters more than the aggregate. A 70% overall inbox rate might mean 95% at Gmail but 30% at Outlook \u2014 revealing an authentication issue specific to Microsoft&#8217;s filters.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What are the different methods for checking deliverability?<\/h2>\n\n\n\n<p>Several approaches exist, each with tradeoffs between accuracy, effort, and coverage.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Seed list testing<\/h3>\n\n\n\n<p>Seed list testing is considered one of the most accurate methods to check email deliverability. You send emails to a network of managed mailboxes across providers (Gmail, Outlook, Yahoo, Zoho, regional services). Since you control the receiving accounts, you can verify the exact placement.<\/p>\n\n\n\n<p>Building your own seed list requires:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Creating accounts at each major provider<\/li>\n\n\n\n<li>Maintaining those accounts (inactive mailboxes get deleted)<\/li>\n\n\n\n<li>Manually checking each inbox after every test<\/li>\n<\/ul>\n\n\n\n<p>Most teams use testing tools that maintain seed networks instead \u2014 same accuracy without the account management overhead.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Manual inbox checks<\/h3>\n\n\n\n<p>The manual inbox check involves sending test emails to your personal Gmail, Outlook, and Yahoo accounts, then checking where they land.<\/p>\n\n\n\n<p>Limitations include<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Covers 3-4 providers at most<\/li>\n\n\n\n<li>No authentication diagnostics or content analysis<\/li>\n\n\n\n<li>Misses regional providers that your international prospects use<\/li>\n\n\n\n<li>Your personal engagement history skews results (providers trust senders you interact with regularly)<\/li>\n<\/ul>\n\n\n\n<p>Hence, manual inbox checks are useful for spot checks, but <strong>not<\/strong> reliable for campaign validation.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Deliverability testing tools<\/h3>\n\n\n\n<p>Automated testing across 50+ providers with detailed diagnostics. You send one email to a provided address list \u2014 the tool checks placement across its seed network and returns a breakdown.<\/p>\n\n\n\n<p>EmailWarmup&#8217;s <a href=\"https:\/\/emailwarmup.com\/email-deliverability-test\" target=\"_blank\" rel=\"noreferrer noopener\">email deliverability test<\/a> works this way:&nbsp;<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Send to the seed addresses<\/li>\n\n\n\n<li>Receive a report within minutes showing inbox rates per provider<\/li>\n\n\n\n<li>Check your authentication status and content flags<\/li>\n<\/ol>\n\n\n\n<p>The advantage over manual testing is <strong>coverage<\/strong>.&nbsp;<\/p>\n\n\n\n<p>Your prospects use Gmail and Outlook, but they also use Zoho, ProtonMail, regional providers like GMX (40 million users in Germany) or Mail.ru (100+ million in Eastern Europe). Tools catch provider-specific issues you&#8217;d never find by checking three personal accounts.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Google Postmaster Tools<\/h3>\n\n\n\n<p>Free data from Google showing how Gmail specifically treats your domain. You get:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Domain reputation (high, medium, low, bad)<\/li>\n\n\n\n<li>Spam rate from user reports<\/li>\n\n\n\n<li>Authentication success rates<\/li>\n\n\n\n<li>Delivery errors<\/li>\n<\/ul>\n\n\n\n<p>The catch is that <a href=\"https:\/\/emailwarmup.com\/blog\/email-deliverability\/google-postmaster-tools\/\" target=\"_blank\" rel=\"noreferrer noopener\">Google Postmaster Tools<\/a> requires sending volume to generate data (typically 100+ emails daily to Gmail). The data is historical, not predictive \u2014 it shows what happened, not what will happen with your next campaign.<\/p>\n\n\n\n<p>Hence, it\u2019s good for ongoing monitoring, but not a substitute for pre-send testing.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Microsoft SNDS<\/h3>\n\n\n\n<p><a href=\"https:\/\/emailwarmup.com\/blog\/email-deliverability\/microsoft-snds\/\" target=\"_blank\" rel=\"noreferrer noopener\">Microsoft SNDS<\/a> is Microsoft&#8217;s equivalent of Outlook and Hotmail, which shows spam complaint rates, <a href=\"https:\/\/emailwarmup.com\/blog\/spam-traps\/\" target=\"_blank\" rel=\"noreferrer noopener\">spam trap<\/a> hits, and IP reputation within the Microsoft ecosystem.<\/p>\n\n\n\n<p>The limitations are the same as Postmaster Tools:&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Historical data<\/li>\n\n\n\n<li>Single provider<\/li>\n\n\n\n<li>Requires volume&nbsp;<\/li>\n<\/ul>\n\n\n\n<p>It\u2019s useful alongside Gmail data, but neither tool tells you where a <em>new<\/em> campaign will land before you send it.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How do you check email deliverability via a test?<\/h2>\n\n\n\n<p>The process depends on your method, but tool-based testing follows a simple pattern.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"2150\" height=\"1192\" src=\"https:\/\/emailwarmup.com\/blog\/wp-content\/uploads\/2025\/07\/Email-deliverability-test.jpg\" alt=\"Email deliverability test\" class=\"wp-image-2556\"\/><\/figure>\n\n\n\n<p>For EmailWarmup&#8217;s free test:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Copy the seed addresses from the <a href=\"https:\/\/emailwarmup.com\/email-deliverability-test\" target=\"_blank\" rel=\"noreferrer noopener\">deliverability test<\/a> page<\/li>\n\n\n\n<li>Open a new email in your ESP (the one you&#8217;ll use for actual campaigns)<\/li>\n\n\n\n<li>Paste the addresses in the &#8220;To&#8221; field<\/li>\n\n\n\n<li>Send with &#8220;test&#8221; as subject and body \u2014 consistency matters for accurate results<\/li>\n\n\n\n<li>Check results in the report (usually within 2-3 minutes)<\/li>\n<\/ol>\n\n\n\n<p>The key detail is to send from the exact infrastructure you&#8217;ll use for real campaigns. Testing from your personal Gmail tells you nothing about how emails from your ESP will perform. Filters evaluate the <em>sending source<\/em> \u2014 domain, IP, authentication \u2014 not just content.<\/p>\n\n\n\n<p>If you&#8217;re testing multiple sending setups (different ESPs, different domains), run separate tests for each. A domain that passes from SendGrid might fail from Mailgun if DKIM isn&#8217;t configured identically.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How do you interpret deliverability test results?<\/h2>\n\n\n\n<p>Results fall into three categories based on inbox placement rate.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Healthy results<\/h3>\n\n\n\n<p>Your sending infrastructure is working properly.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td>Metric<\/td><td>Healthy range<\/td><\/tr><tr><td>Inbox rate<\/td><td>85%+ (90%+ for cold email)<\/td><\/tr><tr><td>Spam rate<\/td><td>Under 5%<\/td><\/tr><tr><td>Unreceived<\/td><td>Under 2%<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p>Promotions placement isn&#8217;t ideal, but it also isn\u2019t critical \u2014 some promotional content naturally sorts there.

Monitor periodically and retest after any infrastructure changes.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Warning signs<\/h3>\n\n\n\n<p>Something needs attention before it becomes a larger problem.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td>Indicator<\/td><td>Likely cause<\/td><\/tr><tr><td>60-80% inbox rate<\/td><td>Authentication gaps or early reputation issues<\/td><\/tr><tr><td>High promotions (40%+)<\/td><td>Content triggers or sending patterns<\/td><\/tr><tr><td>Provider-specific failures<\/td><td>Missing authentication for that provider<\/td><\/tr><tr><td>2-5% unreceived<\/td><td>Possible blocklist or DNS issues<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p>At this stage, verify the authentication setup.

Regular testing catches problems before they damage campaign performance \u2014 waiting until open rates drop means the damage is already done.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1766403884638\"><strong class=\"schema-faq-question\">What&#8217;s the difference between delivery rate and inbox placement?<\/strong> <p class=\"schema-faq-answer\">Delivery rate measures whether the email reached the recipient&#8217;s mail server. Inbox placement measures whether it landed in the primary inbox (versus spam or promotions). A 98% delivery rate with 50% inbox placement means half your &#8220;delivered&#8221; emails are invisible to recipients.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1766403891456\"><strong class=\"schema-faq-question\">Can I check deliverability from any email service provider?<\/strong> <p class=\"schema-faq-answer\">Yes. Any ESP that lets you enter recipient addresses manually works \u2014 Gmail, Outlook, SendGrid, Mailchimp, HubSpot, Klaviyo, Salesforce, and custom SMTP. The test evaluates your sending infrastructure, so send from the exact setup you&#8217;ll use for real campaigns.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1766403896718\"><strong class=\"schema-faq-question\">Why do I have different results for different providers?<\/strong> <p class=\"schema-faq-answer\">Each provider uses its own filtering algorithms and reputation systems. Authentication configured correctly for Gmail might have issues with Microsoft. Blocklists affect providers differently. Content that passes Google&#8217;s filters might trigger Yahoo&#8217;s. Provider-specific results help you target fixes where they&#8217;re needed.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1766403911739\"><strong class=\"schema-faq-question\">Does checking email deliverability affect my sender reputation?<\/strong> <p class=\"schema-faq-answer\">No. Deliverability tests are sent to controlled seed mailboxes, not real recipients. There are no spam complaints, bounces, or engagement signals that could affect reputation. Test as often as needed without risk.<\/p> <\/div> <\/div>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Your email service provider says &#8220;delivered.&#8221; But delivered where?
