Starting a template from a blank editor is the slow part. AI authoring lets you describe the message you want in plain language and get back a complete first draft — subject, layout, copy, and a typed list of the variables it uses — which you then refine in the editor before publishing.

​
What it produces

You give it a channel and a brief (“a friendly welcome email for a new SaaS signup with a button to set up their workspace”), and it drafts channel-appropriate content:
  • Email — a subject line, an optional preheader, a structured body of headings, paragraphs, buttons, lists, and dividers, and optionally a color palette (accent for buttons/links, heading, and body text colors). Colors are applied only when the brief mentions a color, brand, or look/feel; otherwise the email keeps its neutral defaults.
  • SMS — a single message body, kept within SMS length budgets.
  • Push — a short title and body.
Alongside the content it declares the variables it used — snake_case names, types, descriptions, and example values — and reuses variables you’ve already defined when they fit, so you’re not left wiring up placeholders by hand.

​
Where it fits in the workflow

AI authoring is available in two places:
  • Dashboard editor — the Write with AI button in the template editor drafts or rewrites a template inline. Nothing goes live until you review and publish.
  • MCP server — the senderkit_templates_create and senderkit_templates_regenerate tools let an AI agent (Claude, Cursor, etc.) generate templates from a brief. Both tools save the result as a draft and return a link to the editor for review — publishing is always a deliberate human step.
In both cases the draft is a new template version; it only affects real sends once you publish it.

​
What to expect

Treat the output as a strong first draft, not a finished template:
  • Review the copy — it’s a starting point; tighten it to your voice.
  • Check the variables — confirm the names and types match the data you’ll actually pass at send time.
  • Then publish — the draft only affects real sends once you publish it as the current version.
