# How to add a pre-header to an email template?
Email marketing is a powerful tool for engaging with your audience, but optimizing your campaigns for maximum impact requires attention to detail!
One crucial element often overlooked is the pre-header, a valuable asset that can significantly improve the open rate of your email campaigns.
### Understanding the pre-header
The pre-header is the snippet of text that follows the subject line in an email inbox:
By default, the first lines of an email are often displayed as a preview. However, these lines may not always provide valuable information to entice recipients to open the email.

Generic greetings such as *'Dear customer, we are pleased to...'* might not be compelling and a well-crafted pre-header can make a substantial difference 💪

### How to add a pre-header to your email template
To take control of your email pre-headers, you can effortlessly add a pre-header directly within your template in the Message settings tab.
Most email clients display the beginning of the email body right after the subject and pre-header in the inbox preview. To avoid showing this content, you can enable the **Fill in with white space** option. This adds empty space after the subject and pre-header, preventing any text from the email body from appearing.
When the **Fill in with white space** option is enabled, inbox previews will show empty space after the pre-header.
By incorporating this step, you can customize your pre-header text, providing a concise and compelling summary that encourages recipients to open and engage with your emails.
