Designer Studio for legacy templates (classic UI)
Overview
Section titled “Overview”This article is for pre-2022 templates, built with our legacy HTML syntax: use it if your tags are in $tag; format. If you use Liquid templates, see Designer Studio for Liquid templates (classic UI).
Designer Studio holds your signature templates. Signature templates are designed in HTML. Don’t worry if you’re not familiar with HTML: we provide your initial signature templates during onboarding.
- To see which signatures are live, check Signature Assignment (Signatures menu > Signature Assignment). Take care when you edit a live signature.
- We recommend cloning before editing, and using the Preview button before you select Save.
- Need to change an image or link in your signature template? See Changing images and links in legacy templates (classic UI).
