Templates and the Templates API
Create reusable templates with three editors, version them under an alias, and send them by alias or ID with variables.
Updated Feb 10, 2026
Build templates with the HTML editor, the rich-text editor or the Dragit drag-and-drop editor. Templates that share an alias are versions of one template, and only the published version is used when you send by alias.
Manage templates with the Templates API, and send one by passing template and variables to Send an email. See Templates.
