No pop-up notifications. No errors. You may keep sending emails.<\/li>\n<\/ul>\n<p>Behind the scenes, though, there may be other blocking types with <a href=\"https:\/\/snov.io\/blog\/why-are-my-emails-going-to-spam\/\">emails going to spam<\/a> or other Gmail folders (e.g., Promotions or Trash). They can be filtered, auto-deleted, or flagged.<\/p>\n<p>Let\u2019s see how.<\/p>\n<ul>\n<li><strong><strong>Custom-filtered <\/strong><strong>messages<\/strong><\/strong><\/li>\n<\/ul>\n<p>Your recipients can easily block you from the Filters and Blocked Addresses tab by setting a custom filter based on the \u201c<em>Subject<\/em>,\u201d \u201c<em>Has the words<\/em>,\u201d \u201c<em>Has attachment<\/em>,\u201d \u201c<em>Size<\/em>,\u201d or other criteria.<\/p>\n<p><strong>For example:<\/strong><\/p>\n<p>They can apply the label \u201c<em>Overpromotion<\/em>\u201d for aggressive email marketing campaigns or \u201c<em>Pushy sales rep<\/em>\u201d for cold emails. Labeled so, messages will sit in Spam folders for 30 days before auto-removal.<\/p>\n<p>Alternatively, a person may pick a category from the \u201cCategorize as\u201d menu. In this case, your emails will be automatically sent to Promotions, Purchases, Social, Travel, or other folders, depending on the chosen category.<\/p>\n<ul>\n<li><strong><strong>Auto-<\/strong><strong>deleted messages<\/strong><\/strong><\/li>\n<\/ul>\n<p>Another custom filter set via Filters and Blocked Addresses can automatically delete your emails. And in this situation, they never actually end up in Spam folders, but in Trash.<\/p>\n<p><strong>For example:<\/strong><\/p>\n<p>Look at these spammy messages that landed in Trash due to the keywords that triggered my custom filters: \u201c<em>save big<\/em>,\u201d \u201c<em>free<\/em>,\u201d and <em>bonus<\/em>.\u201d<\/p>\n<p><a href=\"https:\/\/snov.io\/blog\/wp-content\/uploads\/2026\/05\/auto-deletion.jpg\" data-fancybox=\"\"> <img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/snov.io\/blog\/wp-content\/uploads\/2026\/05\/auto-deletion.jpg\" alt=\"What happens when someone blocks you on Gmail - auto-deletion - emails are moved to Trash\" width=\"745\" height=\"267\" class=\"aligncenter wp-image-53216\" srcset=\"https:\/\/snov.io\/blog\/wp-content\/uploads\/2026\/05\/auto-deletion.jpg 1450w, https:\/\/snov.io\/blog\/wp-content\/uploads\/2026\/05\/auto-deletion-300x107.jpg 300w, https:\/\/snov.io\/blog\/wp-content\/uploads\/2026\/05\/auto-deletion-1024x367.jpg 1024w, https:\/\/snov.io\/blog\/wp-content\/uploads\/2026\/05\/auto-deletion-768x275.jpg 768w\" sizes=\"(max-width: 745px) 100vw, 745px\" \/> <\/a><\/p>\n<p>And just like Spam, the Trash folder will be emptied in 30 days.<\/p>\n<ul>\n<li><strong><strong>Flagged <\/strong><strong>messages<\/strong><\/strong><\/li>\n<\/ul>\n<p>If Gmail decides your email is suspicious or potentially harmful, it flags it and warns the recipient.

And it would be better to track email deliverability regularly to understand how many emails land in spam rather than in Gmail inboxes.<\/p>\n<div class=\"content-banner default\">\n<p class=\"content-banner__title\">Get the whole deliverability toolkit in one place<\/p>\n<p class=\"content-banner__description\">Raise your inbox placement to 98% with Snov.io<\/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\">Give it a try<\/a><\/div>\n<div class=\"content-banner__img\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/snov.io\/blog\/wp-content\/uploads\/2024\/11\/all-in-one.png\" alt=\"Get the whole deliverability toolkit in one place\" width=\"224\" height=\"224\" \/><\/div>\n<\/div>\n<h2 id=\"find\">How to find out if someone blocked you on Gmail \u2014 real signals<\/h2>\n<p>Now, let\u2019s review the biggest signs that your cold messages or email marketing campaigns may be landing directly in spam due to blocking.<\/p>\n<h3>#1. You stop getting responses to your emails<\/h3>\n<p>If the person isn\u2019t responding to your messages over time, blocking is quite a possible scenario. Yet, before assuming the worst, think about these factors:<\/p>\n<ul>\n<li>People may have abandoned their email addresses, switching to temporary ones, for instance<\/li>\n<li>Your emails are just getting buried in the \u201cGmail graveyard\u201d due to inbox overload<\/li>\n<li>Your messages may accidentally go to Spam or Promotions<\/li>\n<\/ul>\n<p>Now, consider this. In email marketing, the average reply rate is merely <a href=\"https:\/\/belkins.io\/blog\/cold-email-response-rates\" rel=\"nofollow noopener\" target=\"_blank\">5.8%<\/a>. In cold outreach, it\u2019s even lower \u2014 <a href=\"https:\/\/instantly.ai\/cold-email-benchmark-report-2026\" rel=\"nofollow noopener\" target=\"_blank\">3.43%<\/a>. So, remember that silence alone isn\u2019t a straightforward sign of being blocked on Gmail.<\/p>\n<h3>#2. Your engagement metrics collapse overall with bulk blocking<\/h3>\n<p>If you use an <a href=\"https:\/\/snov.io\/email-tracker\">email tracker for Gmail<\/a>, you may notice sudden engagement drops with low or zero:<\/p>\n<ul>\n<li>Replies<\/li>\n<li>Opens<\/li>\n<li>Read-throughs<\/li>\n<li>Clicks<\/li>\n<li>Conversions<\/li>\n<\/ul>\n<p>That\u2019s actually one of the best strategies for checking whether someone has blocked you on Gmail, especially if many recipients did.<\/p>\n<div class=\"content-banner default\">\n<p class=\"content-banner__title\">Wondering if people engage with your emails?<\/p>\n<p class=\"content-banner__description\">Firstbase already uses Snov.io to capture leads first, automate outreach, and monitor engagement on Gmail.<\/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 it for free<\/a><\/div>\n<div class=\"content-banner__img\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/snov.io\/blog\/wp-content\/uploads\/2023\/12\/\u0440\u043e\u0437\u0441\u0438\u043b\u043a\u0430-\u0456\u043c\u0435\u0439\u043b\u0456\u0432-1.png\" alt=\"Wondering if people engage with your emails\" width=\"224\" height=\"224\" \/><\/div>\n<\/div>\n<h3>#3. You don\u2019t receive bounce notifications<\/h3>\n<p>This may sound weird, but not getting <a href=\"https:\/\/snov.io\/blog\/email-bounce-back\/\">bounce-back emails<\/a> is another clue that something might be wrong.<\/p>\n<p>A bounced message isn\u2019t pleasant, per se, as it damages your sender reputation and decreases email deliverability. But when you send yet another email and receive a bounce, it may at least confirm other reasons for not responding to your messages or engaging with them.<\/p>\n<p>These reasons may coincide with the following notifications of deliverability issues in hard or soft bounces:<\/p>\n<ul>\n<li>\u201cAddress not found\u201d (because of a deactivated or invalid email address)<\/li>\n<li>\u201cMessage not delivered\u201d (because of a temporary server error or connection timeout)<\/li>\n<li>\u201cRecipient inbox full\u201d (self-explanatory)<\/li>\n<li>Or others<\/li>\n<\/ul>\n<p>When such bounces occur, you typically get emails with subject lines: \u201c<em>Delivery Status Notification (Failure)<\/em>, just like in the example below.<\/p>\n<p><a href=\"https:\/\/snov.io\/blog\/wp-content\/uploads\/2026\/05\/no-bounce-back-emails.jpg\" data-fancybox=\"\"> <img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/snov.io\/blog\/wp-content\/uploads\/2026\/05\/no-bounce-back-emails.jpg\" alt=\"How to know if someone blocked you on Gmail - no bounce-back emails like this\" width=\"745\" height=\"376\" class=\"aligncenter wp-image-53218\" srcset=\"https:\/\/snov.io\/blog\/wp-content\/uploads\/2026\/05\/no-bounce-back-emails.jpg 1350w, https:\/\/snov.io\/blog\/wp-content\/uploads\/2026\/05\/no-bounce-back-emails-300x151.jpg 300w, https:\/\/snov.io\/blog\/wp-content\/uploads\/2026\/05\/no-bounce-back-emails-1024x517.jpg 1024w, https:\/\/snov.io\/blog\/wp-content\/uploads\/2026\/05\/no-bounce-back-emails-768x387.jpg 768w\" sizes=\"(max-width: 745px) 100vw, 745px\" \/> <\/a><\/p>\n<p>When someone blocks you, on the other hand, you receive nothing: no delivery status notification or alert.<\/p>\n<p><strong>\u2192 Learn how to fix the problem of <\/strong><a href=\"https:\/\/snov.io\/knowledgebase\/what-are-hard-and-soft-email-bounces\/\"><strong>hard and soft bounces<\/strong><\/a><strong>.<\/strong><\/p>\n<h3>#4. You send a test email and get an active response<\/h3>\n<p>This is a much stronger signal than those I mentioned previously, yet not a sure-fire one.<\/p>\n<p><strong>For example:<\/strong><\/p>\n<p>Let\u2019s say you\u2019re used to launching email marketing campaigns or cold emails from one Gmail account. Now, you switch to another account. Suddenly, the person is actively responding.<\/p>\n<p>That doesn&#8217;t guarantee you were blocked, but it may hint that the recipient treats your previous sender identity differently.<\/p>\n<h3>#5. You reach out and confirm or refute it via another communication channel<\/h3>\n<p>Honestly? To me, it looks like the best advice on how to find out if someone blocked you on Gmail without guessing. It\u2019s a guaranteed way to obtain feedback (an affirmative answer or denial) because you simply ask the person via:<\/p>\n<ul>\n<li>Phone call<\/li>\n<li>Messaging apps like WhatsApp or Facebook Messenger<\/li>\n<li>SMS<\/li>\n<li>Social platforms (primarily, LinkedIn for B2B or Instagram for B2C)<\/li>\n<\/ul>\n<p>Here\u2019s a short template to make it easier for you:<\/p>\n<div style=\"width: 100%; display: flex; justify-content: center; margin: 2em 0;\">\n<div style=\"display: inline-block; border: 1px solid #575757; width: 100%; box-sizing: border-box; overflow: hidden;\">\n<table style=\"width: 100%; border-collapse: collapse; margin: 0; padding: 0;\">\n<tbody>\n<tr>\n<td style=\"padding: 18px; line-height: 1.7; font-family: Arial, sans-serif; font-size: 15px; color: #000;\">&nbsp;<\/p>\n<p><em><span style=\"font-family: georgia, palatino, serif; font-size: 12pt;\">Hey [First Name],<\/span><\/em><\/p>\n<p><em><span style=\"font-family: georgia, palatino, serif; font-size: 12pt;\">I&#8217;ve recently sent you a couple of emails and wanted to check whether they actually reached your inbox.<\/span><\/em><\/p>\n<p><em><span style=\"font-family: georgia, palatino, serif; font-size: 12pt;\">Just wondering whether they got filtered by Gmail and landed in spam, or if there\u2019s any chance my address was accidentally blocked.<\/span><\/em><\/p>\n<p><em><span style=\"font-family: georgia, palatino, serif; font-size: 12pt;\">No worries either way \u2014 just wanted to clarify.

Since then, it has implemented even fiercer policies specifically for bulk senders (over 5,000 emails\/day).<\/p>\n<p>Several of the most critical Gmail rules relate to the following aspects:<\/p>\n<ul>\n<li><strong>Email authentication:<\/strong> SPF, DKIM, and DMARC<\/li>\n<li><strong>User subscription:<\/strong> Double opt-in and one-click unsubscribe (the latter is required only for promotional messages sent in bulk)<\/li>\n<li><strong>Spam<\/strong><strong> rate:<\/strong> Ideally, it should be below 0.1% and never hit more than 0.3%<\/li>\n<li><strong>Display names:<\/strong> Clear and not impersonated<\/li>\n<li><strong>Formatting and content:<\/strong> Proper HTML structure, visible and understandable links, non-deceptive subject lines, etc.<\/li>\n<li><strong>Sending volume and frequency:<\/strong> Gmail severely forbids sudden volume spikes or sending emails in bursts<\/li>\n<\/ul>\n<p>Remember that messages sent in bulk all of a sudden can look suspicious to Gmail. You should gradually increase your sending activity. Experts particularly advise doing an <a href=\"https:\/\/snov.io\/email-warm-up\">email warm-up<\/a> for newly created accounts to prepare them for mass sending.<\/p>\n<p style=\"text-align: center;\"><iframe loading=\"lazy\" width=\"560\" height=\"315\" src=\"\/\/www.youtube.com\/embed\/WqfZfqPbDPA?si=t4iTJPypKTe7J9oi\" title=\"YouTube video player\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen=\"allowfullscreen\"><\/iframe><\/p>\n<h3>Make it easy for subscribers to opt in and out<\/h3>\n<p>That\u2019s a very important practice for email marketing, which every sender should follow.
