Avoid having any part of your email hidden by using fluid coding techniques that adjust the width of your email to the width of the message window. Alternatively, ensure your emails are no wider than 800px.<\/p>\n<p>We did spot this message in the T-Online.de inbox while testing in Chrome on a laptop:<\/p>\n<figure id=\"post-16562 media-16562\" class=\"aligncenter nudged\"><img decoding=\"async\" class=\"\" src=\"https:\/\/www.litmus.com\/wp-content\/uploads\/2020\/04\/tonline-germannotice.png\" alt=\"T-Online.de\"><\/figure>\n<p>In case you\u2019re not fluent in German, this message translated to:<\/p>\n<blockquote><p>This e-mail has been scaled down so that it can be displayed completely. Undo scaling.<\/p><\/blockquote>\n<p>This message is displayed when the size of the window is reduced to less than 800px, as the email has been scaled down to fit the size of the window. Unfortunately, media queries aren\u2019t supported by T-Online.de, so they won\u2019t help with how the email is scaled down. After the window reaches the 645px width mark, the email is no longer scaled\u2014any part of the email that is wider than this number is hidden on the right side of the window, with no way to scroll to see it.<\/p>\n<h2>HTML and CSS Support<\/h2>\n<div style=\"background: #f6f6f6;

Use background images as enhancements to your designs that aren\u2019t missed if they\u2019re not there.<\/li>\n<li><strong>Embrace the power of the animated GIF<\/strong>\u2014with no support for HTML5 video the best way to add some motion to your email would be through <a rel=\"noopener\" href=\"https:\/\/litmus.com\/blog\/a-guide-to-animated-gifs-in-email\" target=\"_blank\" rel=\"noopener noreferrer\">animated GIFs<\/a>.<\/li>\n<\/ul>\n<h2>We&#8217;d love to hear from you<\/h2>\n<p>Did you discover a rendering quirk in T-Online.de that we missed?
