Editing Custom email headers and footers (section)

=== Introduction ===
The ability to add custom email headers and footers allows businesses to incorporate non-removable pieces of content into every outgoing email. These elements are particularly useful for reinforcing branding elements such as logos, taglines, or specific messages intended for your audience. 

It is important to note that once you have added a custom header or footer, it will be automatically included in all future campaigns and automation emails. However, this customization does not reflect in the email designer interface, and it will only be visible in test and live sends. This section will outline how to create and manage custom email headers and footers effectively.
