This trend results in an increasing amount of unwanted email.</p> <p>Web administrators have come up with clever ways to protect against this by writing out email addresses (i.e., help [at] cloudflare [dot] com) or by using embedded images of the email address. However, you lose the convenience of clicking on the email address to automatically send an email.<br/><br/>By enabling Cloudflare Email Address Obfuscation, email addresses on your web page will be obfuscated (hidden) from bots, while keeping them visible to humans. In fact, there are no visible changes to your website for visitors.</p> <div class="cf-sidebar cf-sidebar-bgcolor-note"> <div class="cf-sidebar-icon far fa-sticky-note fa-2x"> </div> <div>For email address obfuscation to work in Cloudflare, a page must have a MIME type (Content-Type) of "text/html" or "application/xhtml+xml". </div> </div> <hr/> <h2>Verify email address obfuscation</h2> <p>Cloudflare enables email address obfuscation automatically when you sign up. </p> <p>To verify email address obfuscation in the Cloudflare dashboard:</p> <p>1. Log in to the Cloudflare dashboard.</p> <p>2. Ensure the website you want to verify is selected.</p> <p>3. Click the <strong>Scrape Shield</strong> app.</p> <p>4. Under <strong>Email Address Obfuscation</strong>, check that the toggle is set to <em>On</em>.</p> <p>Alternatively, you can retrieve the page source from an HTTP client such as CURL, an HTTP library, or browser's view-source option. Then, review the source HTML to confirm that the address is no longer present. </p> <hr/> <h2>Troubleshoot email obfuscation</h2> <p>To prevent unexpected website behavior, email addresses are not obfuscated when they appear in:</p> <ul> <li>Any HTML tag attribute, except for the <em>href</em> attribute of the <em>a</em> tag.</li> <li>Other HTML tags:</li> </ul> <p class="wysiwyg-indent5"><em>script</em> tags: <script></script></p> <p class="wysiwyg-indent5"><em>noscript</em> tags: <noscript></noscript></p> <p class="wysiwyg-indent5">HTML comments: </p> <p class="wysiwyg-indent5"><em>textarea</em> tags: <textarea></textarea></p> <p class="wysiwyg-indent5"><em>xmp</em> tags: <xmp></xmp></p> <p class="wysiwyg-indent5"><em>head</em> tags: <head></head></p> <ul> <li>Any page that does not have a MIME type of "text/html" or "application/xhtml+xml"</li> </ul> <hr/> <h2>Prevent Cloudflare from obfuscating email</h2> <p>To prevent Cloudflare from obfuscating emails, you can:</p> <ul> <li>Add the following comment in the page HTML code: </li> </ul> <p class="wysiwyg-indent5"><em>you</em> <em>email addresses, goes here</em></p> <ul> <li>Return email addresses in JSON format for AJAX calls, making sure your web server returns a content type of "application/json".<br/><br/></li> </ul></div> </div> </section> <footer> <div class="article-footer"> <div class="article-share"> <ul class="share"> <li><a href="https://web.archive.org/web/20200929082908/https://www.facebook.com/share.php?title=What+is+Email+Address+Obfuscation%3F&u=https%3A%2F%2Fsupport.cloudflare.com%2Fhc%2Fen-us%2Farticles%2F200170016-What-is-Email-Address-Obfuscation-" class="share-facebook">Facebook</a></li> <li><a href="https://web.archive.org/web/20200929082908/https://twitter.com/share?lang=en&text=What+is+Email+Address+Obfuscation%3F&url=https%3A%2F%2Fsupport.cloudflare.com%2Fhc%2Fen-us%2Farticles%2F200170016-What-is-Email-Address-Obfuscation-" class="share-twitter">Twitter</a></li> <li><a href="https://web.archive.org/web/20200929082908/https://www.linkedin.com/shareArticle?mini=true&source=Cloudflare&title=What+is+Email+Address+Obfuscation%3F&url=https%3A%2F%2Fsupport.cloudflare.com%2Fhc%2Fen-us%2Farticles%2F200170016-What-is-Email-Address-Obfuscation-" class="share-linkedin">LinkedIn</a></li> </ul> </div> </div> <div class="article-votes"> <div> <span class="article-votes-question">Was this article helpful?</span> <small class="article-votes-count"> <span class="article-vote-label" data-helper="vote" data-item="article" data-type="label" data-id="200170016" data-upvote-count="1125" data-vote-count="1720" data-vote-sum="530" data-vote-url="/hc/en-us/articles/200170016/vote" data-value="null" data-label="1125 out of 1720 found this helpful">1125 out of 1720 found this helpful</span> </small> </div> <div class="article-votes-controls" role="radiogroup"> <a class="button article-vote article-vote-up" data-helper="vote" data-item="article" data-type="up" data-id="200170016" data-upvote-count="1125" data-vote-count="1720" data-vote-sum="530" data-vote-url="/hc/en-us/articles/200170016/vote" data-value="null" data-label="1125 out of 1720 found this helpful" data-selected-class="null" aria-selected="false" role="radio" rel="nofollow" title="Yes" href="#"></a> <a class="button article-vote article-vote-down" data-helper="vote" data-item="article" data-type="down" data-id="200170016" data-upvote-count="1125" data-vote-count="1720" data-vote-sum="530" data-vote-url="/hc/en-us/articles/200170016/vote" data-value="null" data-label="1125 out of 1720 found this helpful" data-selected-class="null" aria-selected="false" role="radio" rel="nofollow" title="No" href="#"></a> </div> </div> <div class="article-return-to-top"> <a href="#article-container">Return to top <span class="icon-arrow-up"></span> </a> </div> </footer> </article> </div> </div> </div> <section class="article-footer-search-wrapper footer-search-wrapper"> <section class="container"> <section class="content-wrapper"> <section> <h1>Not finding what you need?</h1> <p>Searching can help answer 95% of support questions.
