For instance you can <a href=\"\/support\/email\/blacklist-check\/request-a-delisting-from-a-blacklist\/\" target=\"_blank\" rel=\"noopener\">request a delisting from a blacklist<\/a>.<\/p>\n<h2>What is a blacklist?<\/h2>\n<p>Depending on who you ask, most people who attempt to track the global level of spam being sent, estimate anywhere between <span style=\"color: red;\">80%-95%<\/span> of all email transmitted daily on the Internet is spam.<\/p>\n<p>That means that simply relying on manually going through all of your own email, is not the most efficient method for weeding through spam messages anymore these days.<\/p>\n<p>As such there are public blacklists of mail servers that have been relaying spam. This allows other mail servers to check if an email is from a server&#8217;s IP address that might have possibly been flagged for sending spam in the past.<\/p>\n<p>For instance you can use our <a href=\"\/support\/tools\/blacklist-check\/\" target=\"_blank\" rel=\"noopener\">blacklist check<\/a> tool to check if your server is currently listed on any public blacklists.<\/p>\n<h2>Why is my server on a blacklist<\/h2>\n<p>It&#8217;s not uncommon for a mail IP address to end up on a public blacklist, especially on a shared server. It could be due to overall volume of mail coming from that server, or messages seem to have characteristics of spam in them.<\/p>\n<p>Another common cause is email forwarders. If you have <span style=\"color: red;\">user@example.com<\/span> forwarding to <span style=\"color: red;\">user@yahoo.com<\/span>, if <span style=\"color: red;\">user@example.com<\/span> is spammed, our mail server could forward that onto Yahoo.<\/p>\n<p>Their servers might see our mail IP address as relaying the spam message to their server, even though it wasn&#8217;t the originating server of the spam.<\/p>\n<h2>Working around blacklisting problems<\/h2>\n<p>We monitor email queues for signs of delivery issues with major email providers. If you&#8217;re having an issue emailing a certain provider and you need to get a message sent out urgently I would recommend following the steps in my guide on <a href=\"\/support\/email\/send-mail-via-gmail-when-server-ip-is-blocked\/\" target=\"_blank\" rel=\"noopener\">sending mail via Gmail when server IP is blocked<\/a> to still get your message out in a timely manner.<\/p>\n<p>After that, typically you&#8217;d want to request to have the mail server&#8217;s IP address de-listed from any blacklists that it&#8217;s currently on. In order to do this you can read my guide on <a href=\"\/support\/email\/blacklist-check\/request-a-delisting-from-a-blacklist\/\" target=\"_blank\" rel=\"noopener\">requesting a delisting from a blacklist<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>In this guide I&#8217;m going to explain why it&#8217;s common for mail servers to get blacklisted, and what you can do if your own server has been blacklisted.
