Key takeaways

  • Preview panes are often the first look readers get. Optimize that small space for trust, clarity and action.
  • Show your brand logo and name prominently (top-left) so they aren’t cut off in vertical or horizontal preview panes.
  • Keep preview pane copy minimal. Remove filler so the most important message shows.
  • Don’t rely on external images in the preview: 59% of users block images, so code visible preview content in HTML.
  • Avoid link overload; too many links in the preview looks cluttered and resembles spam.
  • Make a single, clear call to action the focus of the preview to drive opens and clicks.

Introduction

If you’ve read one blog about optimizing you’re marketed emails, it feels like you’ve read them all, right? With so much generic information floating around the web, the talk surrounding optimization has definitely grown a little stale. However, there’s one interesting part of the process that doesn’t seem to actually get much attention – the emergence of preview panes across mail platforms. Considering that this is the first look readers have at what you’re trying to show off, giving some serious attention to how your brand comes across in these little windows definitely makes sense. To help you make a great first impression in the preview pane, here are some smart tips for optimizing your messages when they take center stage on this limited screen real estate.

Put an Emphasis on Building Trust

Considering that the inbox can be a “Wild West” of sorts with so many scams and shady messages floating around, the best way to avoid having your emails hit the virtual trash bin is to make it readily apparent to your reader that the message they’re looking at is legit. This means showing off your brand logo and name prominently in a place that won’t be cut off in either vertical or horizontal preview panes. The top left corner of the message is your best bet if you’re aiming to keep things visible. By sticking to smart formatting like this, you can avoid turning off skeptical readers before they open your email.

Limit the Amount of Copy in the Preview Pane

While it might seem a little odd to skimp on the body of the message, having a solid brick wall of text in the preview pane isn’t the way to go about your email marketing campaign. Not only is this not an attractive way to showcase your deals and offers, it also cuts down on the chances of your audience seeing the really important parts of the message. Before firing off a new round of content, take a moment to think about everything that shows up in the preview pane. If you even have the slightest concern that something in this window might be extraneous, it’s probably a good idea to go ahead and pull it. Otherwise, you could be kicking yourself when you realize that the first thing viewers see isn’t an enticing offer, but rather filler content that shouldn’t have been there in the first place.

HTML is Your Friend

With 59 percent of users blocking images in their email clients, leaning heavily on external images isn’t a good idea in the preview pane. Sure, these images can help you track open rates, but they are most definitely suited for the body of the message. When possible, coding the portions of the message that popup in the preview pane with HTML is the best way to work around the rise of image suppression. Naturally, this might require a little extra work if you’re trying to keep your logo prominently displayed, but you’ll definitely be happy with results. After all, if you don’t like seeing those annoying red “X’s” that signify a blocked image in your inbox, what makes you think that your audience will like it when it comes to your marketed emails?

Avoid Link Overload

One of the most grievous faux pas your brand can inadvertently slip into is link overload. This means cramming excessive amounts of links into the space that shows up on a horizontal or vertical preview pane. Obviously, you’re going to need links to products, deals, or your homepage somewhere in the message. However, the real problem starts when all of these, and then a few more, end up crowding a preview page and turning it into a cluttered mess. Adding in that plenty of spam messages from shadier brands or scammers come jammed with links as well, doesn’t put your messages in good company that you’d be proud to keep anyways.

Focus on the Call to Action

Finally, the biggest thing your message can do in the preview pane is generate a powerful call to action. At the core of any marketing message that shows up in your audiences’ inboxes is an incentive to do something with your products or services. Whether it is a limited time offer or a handy guide for using these retail items in new and exciting ways, having a clear and concise call to action not only helps streamline your message as a whole, it also keeps your preview focused and enticing for viewers. Before worrying about images, content length, or anything else, making sure you have this fundamental piece of the puzzle in place in the best way to keep your message on track and give your readers all the reason they need to read on after the preview.

FAQ

Why does the email preview pane matter for my marketing emails?

The preview pane is the first, limited window many readers see of your message. It shapes first impressions and determines whether recipients open the email, so optimizing what appears there matters more than broad or generic formatting.

How can I make my email look legitimate in the preview pane?

Build trust by showing your brand logo and name prominently in a location that won’t be cut off (the top-left corner is recommended); clear branding helps differentiate your message from scams and shady mail.

How much body copy should I let appear in the preview pane?

Limit the amount of copy visible and avoid a dense block of text. If any content in the preview feels extraneous, remove it so readers see the most enticing parts first.

Should I use images in the preview pane to track opens or show branding?

Relying on external images is risky because 59% of users block images; images can help track opens but are better placed in the email body. When possible, code the portions that appear in the preview with HTML so branding and messaging remain visible even with image suppression.

How many links should I include in the preview pane?

Avoid link overload. Include essential links but don’t cram the preview with multiple links. Excessive links clutter the small space and can make your message resemble spam.

How should I craft a call to action for the preview pane?

Make the call to action clear and concise; centre the preview on a single incentive (eg. a limited-time offer or useful guide) so the preview is focused and entices readers to open and act.

What can make my email look like spam in the preview pane and how do I avoid it?

Elements that mimic spam include many links, dense filler text and lack of clear branding. To avoid that, display your logo and name clearly, limit visible copy and links and present a straightforward call to action.
