Samsung Now Available in Litmus Email Previews


We’re excited to announce the most recent addition to Litmus Email Previews: Samsung Mail.

Samsung is the most popular Android device manufacturer. As of December 2017, Samsung devices held 47% of the Android market share. Huawei comes in a distant second with only 6.6% of Android the market share. A possible reason for Samsung’s dominance in the market is the sheer number of Samsung devices that are available—mobile devices, phablets, and tablets. Devices range from mid- to high-end, and there are even phone series’ that cater to specific geographic regions—for example the Samsung Galaxy J series which is only available in Japan.

It’s not just Samsung devices that are popular. As of December 2017, Samsung’s native email client had 5% of the email client market share. Despite there being such an array of email apps available on Android devices—including Gmail and Inbox by Gmail—many Samsung device owners are still choosing to use the native email client.

We took a closer look at this email client and how it renders email. Here’s what we found:

Message View

Emoji in subject line


Message clipping



Samsung’s email client will show the entire subject line of an email when it’s being viewed. This means if you’re using long subject lines your subscribers will have to scroll a little bit more vertically just to see your email.

Style in <head>


Inline style support


Media query support


CSS attribute selector support

Animated GIF support


ALT text support


Styled ALT text support

Interactivity (checkboxes)


Animation (transitions/keyframes)


Samsung Rendering “Quirks” and Notes

While reviewing how emails rendered on Samsung’s native email client, there were a few quirks we noticed that email marketers should be aware of:

  • Margins work on elements like the <p> tag and <h> tags, however not on <div>s or <table>s. Margins are commonly used to create space around elements in email. As an alternative, you could use the <br> tag to create space between elements in which the margin attribute doesn’t work.
  • Max-width works across <div>s and <table>s, but not on individual table cells. Avoid using the max-width attribute on these elements. A workaround would be to use a <div> inside an individual table cell and set the max-width on that element.
  • CSS transitions do work in this email client! However, CSS keyframe animation isn’t supported. So if you want to include CSS animation in your emails, we’d suggest sticking to CSS transitions.
  • We noticed in a few tests that the Samsung app would add padding around emails, resulting in white borders around an entire campaign. While we don’t have a fix yet, it’s important to note.
  • Samsung automatically links addresses and phone numbers, and applies a default link styling to them—underlined and blue. While this comes in handy for users who can for example tap an address and instantly have that address open in Google Maps, this can be in conflict with your email’s design.
    You can override the default link styling by adding this Samsung specific style declaration to your <style> block:

    #MessageViewBody a {
        color: inherit;
        text-decoration: none;
        font-size: inherit;
        font-family: inherit;
        font-weight: inherit;
        line-height: inherit;

Make Your Email Designs Bulletproof

If you’re using media queries to change the layout of your design set at specific screen sizes for specific devices, you may want to change that. With the vast range of Samsung devices—not just mobile devices but tablets and even phablets—all with different screen sizes, there aren’t just a few mobile device screen sizes to support. The solution is to use device agnostic media queries which change the email design based on where that design breaks instead of specific screen sizes (We use this technique with our emails at Litmus.).

Targeting Samsung’s Email Client Using CSS

Just like it’s possible to target the desktop Outlook email client using MSO conditional comments, email developers can target the Samsung email client using CSS.

Email developer Mark Robbins noticed that on the Samsung Galaxy S6 the ID MessageViewBody is added to the <body> tag followed by a <div> with the ID MessageWebViewDiv. To target the Samsung email client simply add the following CSS to your email:

#MessageViewBody .yourclassnamehere { }

And in the HTML, for any element that needs this CSS applied to it, add the class name defined to the element:

<div class=”yourclassnamehere”></div>

During our testing, we also noticed that Samsung removes any ID you may have already added to your <body> tag, and adds its own. So instead of using an ID in the <body> tag, inline any CSS you want to be applied to the whole body of the email into the <body> tag to avoid it getting stripped when the ID is removed in Samsung Mail.
