Change the Spacing at the Top of an Email
By default, Klaviyo adds 50 pixels of white space at the top of each email. This padding is added because of the different ways some email clients render emails. With some email clients (for example, certain versions of Outlook) there is no natural spacing built-in. By adding default spacing, you can ensure that your emails will render more consistently across different email clients and devices.
However, if you'd like to modify this default setting, you can click Styles within an email template and then adjust the Margin Top value.
