Disabling CSS inlining

When Direct Mail sends or previews your message, it automatically inlines all CSS styles in your HTML email (including linked stylesheets). Most web-based email clients do not render CSS styles unless they are inlined.

However, if you do not want this behavior, you can disable CSS inlining. Here's how:

  1. Choose Direct Mail > Preferences from the menu bar
  2. Select the Messages tab
  3. Uncheck the "Convert embedded and external CSS to inline styles" checkbox

You can use the Preview window in View Source mode to see the effects of enabling or disabling CSS inlining.


If you turn off CSS inlining, we recommend running a full design test on your email before sending it. Some email clients (like Gmail) do not honor any CSS styles unless they are inlined, so you may want to use the design test to verify that your email looks the way you want before you send it out.
