Make the Best First Impression with Subject Line Checker in Litmus

[ 0 By

Your from name, subject line, and preview text are your ultimate first impression in the inbox. They encourage your subscribers to open and read your email. Without an open, there are no clicks; without clicks, there are no conversions. For many email campaigns, success depends on that first impression.

That’s a lot of pressure. (Cue David Bowie and Freddie Mercury.)

That’s why we’re thrilled to (re) introduce Subject Line Checker, available in all paid Litmus plans and found in Litmus Builder.

RE-INTRODUCING: SUBJECT LINE CHECKER

This isn’t the first time we’ve had a Subject Line Checker tool. While our initial tool was extremely helpful, we wanted it to be more contextual and proactive, so folks could catch any potential issues before they happened. We went back to the drawing board.

Just as we were banging our heads against said drawing board, Austin Woodall posted an amazing tool he built to help preview subject line and preview text in Gmail and iOS in the Litmus Community. We instantly knew this was the vision for the future Subject Line Checker. We enlisted Austin to help expand upon this concept to build over 15 email client previews and we’re excited to share the re-imagined Subject Line Checker with the world.

WHAT’S NEW WITH SUBJECT LINE CHECKER?

Subject Line Checker lets you preview your from name, subject line, and preview text in real time in over 15 popular email clients. It’s easier, faster, and more contextual than ever before. Plus, it’s directly integrated with Litmus Builder.

 

 

INSTANTLY PREVIEW SUBJECT LINES AND PREVIEW TEXT

After checking your previews, you can easily edit the from name, subject line, and preview text in the input fields. Any edit to those fields will be updated in real time in the email client preview below. You can even insert emojis into your subject line using the emoji dropdown menu or copy and paste them into the input fields. 💯

 

 

Subject Line Checker automatically populates the from name with your Litmus account email address and subject line with the Builder document title. You can use the data-preview-text attribute on an HTML element in your email for your desired preview text to populate in that input field.

<div data-preview-text>This text will pre-populate into the preview text input field</div>

The input field labels will warn you of any potential issues, such as:

  • Your subject line may be too long
  • Emojis aren’t supported in your subject line
  • Your preview text may be too long or too short

You can also see an overview of potential issues for all available email clients at a glance in the left hand sidebar. For example, we can see in the image above that our subject line may be too long and that emojis aren’t supported. By default, you can view all email clients, but you can filter your clients so that you’ll only see what issues need to be addressed. These update in real time as you make edits to your subject line and preview text.

To navigate between email clients, you can either click on an email client directly in the left hand sidebar, click on the left or right arrows in the preview pane, or use the left or right arrow keys on your keyboard to toggle through them. For mobile email clients, you can also switch between portrait and landscape view by clicking on the icons in the bottom right or by using the up or down arrow keys.
