{% hint style="success" %}
**Help text**: Add a short description to explain the purpose of the Email Field option, offering context or clarification when the customer enters the information. Help text can be displayed as Tooltip or Content (Below/Beside the option title, Below the option).
{% endhint %}

**Placeholder text:** Display placeholder text inside the Email Field as a faded, lighter color. This text disappears when the customer starts typing and is often used to give customers a clear example of what should be filled in the field.
