This is called a hard bounce. It refers to a permanent issue that makes the email address unusable. Understanding hard bounces helps you maintain a clean email list and prevent deliverability issues.<\/p>\n<h2 id=\"what-are-hard-bounces\">What are hard bounces?<\/h2>\n<p>A hard bounce means that an email address is invalid or can no longer receive emails permanently. This is different from a soft bounce, which is usually temporary.<\/p>\n<ul>\n<li aria-level=\"1\"><b>Invalid email address:<\/b> the address is misspelled (e.g. <i>piet@gnail.com<\/i>) or the account no longer exists. This often occurs with outdated lists or addresses that were never active.<\/li>\n<li aria-level=\"1\"><b>Non-existent domain:<\/b> the part after the @ symbol is invalid or no longer active, for example when a company has closed or the domain has expired.<\/li>\n<li aria-level=\"1\"><b>Blocked by the server:<\/b> the recipient\u2019s mail server rejects your emails. This may happen because your domain or sender address is blacklisted, or because the recipient has explicitly blocked your domain.<\/li>\n<\/ul>\n<h2 id=\"how-does-xendy-handle-this\">How does Xendy handle this?<\/h2>\n<p>You don\u2019t have to do anything. Xendy automatically detects hard bounces and immediately marks these addresses as \u2018<b>Inactive<\/b>\u2019. This prevents you from continuing to send to invalid addresses and protects your send reputation.<\/p>\n<h2 id=\"why-is-this-important\">Why is this important?<\/h2>\n<p>Hard bounces directly affect how providers like Gmail and Outlook evaluate your emails. The lower your number of hard bounces, the higher the chance your emails will arrive in the inbox. That\u2019s why Xendy automatically ensures that hard-bounced addresses are no longer emailed.<\/p>\n<h2 id=\"frequently-asked-questions\">Frequently Asked Questions<\/h2>\n<div class=\"accordion\">\n\t<div id=\"accordion-1768775603\" class=\"accordion-item\">\n\t\t<a id=\"accordion-1768775603-label\" class=\"accordion-title plain\" href=\"#accordion-item-what-is-a-hard-email-bounce?\" aria-expanded=\"false\" aria-controls=\"accordion-1768775603-content\" >\n\t\t\t<button class=\"toggle\" aria-label=\"Toggle\"><i class=\"icon-angle-down\"><\/i><\/button>\n\t\t\t<span>What is a hard email bounce?<\/span>\n\t\t<\/a>\n\t\t<div id=\"accordion-1768775603-content\" class=\"accordion-inner\" aria-labelledby=\"accordion-1768775603-label\" >\n\t\t\t\n<p>A hard bounce means that an email address is invalid or can no longer receive emails permanently.
