Setting preview text

Setting the preview text of your emails is often overlooked, but it's a surprisingly important part of your email campaigns that can really help to boost open rates.

Preview text appears just after the subject line) in your recipients' inbox, and gives a glimpse of the content of your email.

When busy recipients scan their email inboxes deciding what to open or ignore, your subject line may be the first thing to catch their attention. But the preview text could be what seals the deal — convincing them to proceed and open your email.

You may have crafted the perfect subject line, but ignore your preview text and your email could easily be ignored.

Think of preview text as your secondary subject line. Both are the store-fronts to your email campaigns. So make sure to make them enticing.

How to add preview text to your emails

In the new email builder

Preview text is displayed prominently in the email builder — just below the "To" and "Subject Line" fields, and before your main message content.

Enter your preview text in the field provided. You can even use Variables in the preview text field if you want to personalise the message to each recipient.

In the old email editor

Open the EcoSend drag & drop message composer canvas, then click Body from the far left-hand side menu.

Scroll down to Email Settings and the Preheader Text box.

Then simply add in your content, make it nice and snappy, and you're good to go! 🎉
