Hi @Caitlyn Smith, welcome to the community,

The line “Heart logo for Mi Vida...” is sometimes known as the “preview text” of an email.  Depending on different email clients (Gmail, Outlook, Apple Mail, etc), they show a little preview of the email usually taken from the first few lines of your email to let users see more than just the Subject Line to decide if they want to open the email or not.

In Klaviyo, you can set your preferred copy in all messages (Campaigns and Flow Messages) instead of letting the email client determine the preview text.  You can do this by entering your preferred “Preview Text” copy in the “Campaign content” step or in the Flow message’s “Subject and sender” panel when you select the message in the Flow. 

Campaign Message Preview Text

• In Campaigns, after the “Recipients” step, proceed to the Content Step
• Set the “Preview Text” you want to show after the Subject Line.
• Click “Continue to Review” to make sure its saved

Flow Message Preview Text

• In Flows, select the message you want to edit
• In the email detail panel on the right, click on “Edit” in the upper right corner
• Add your Preview Text and make sure to click “Save” to confirm your changes.

Just note, different email clients show different amount of text so make sure to put the most important information up front and do tests on popular email clients to see what is shown.  It also can vary by the user’s device system preferences (e.g. Font Size, etc) - so it’s not always going to be consistent from user to user.  

Here is a good/bad examples if the focus is on the “20% OFF”

• (Bad) :  Enjoy the Holiday Festivities, Shop Today to Save 20% OFF 
• 🟢 (Good) : Save 20% OFF Today, Enjoy the Holiday Festivities.

Hope that helps!
