Describe the audience, goal, copy direction, and send constraint in Codex or Claude Code.
Prompt in. Branded email out.
See how a customer prompt becomes a validated, branded email template using the same blocks the Zen Tools email service renders.
Users describe the email. Zen Tools structures, validates, and test-sends it.
The customer controls the logo, colors, footer, public assets, and reply-to address. Zen Tools sends from its shared sender, routes replies to the workspace address, and blocks live sends until the template validates.
Save the customer logo, colors, footer, public assets, and workspace reply-to address.
Zen Tools converts the brief into article, markdown, stat_block, and cta sections.
The MCP validates the JSON/YAML payload and renders the email before it can be sent.
Send the rendered template to yourself first, then approve the live recipient list.

Four public blocks cover the customer-facing template surface.
Codex or Claude Code can write the content. Zen Tools turns it into this constrained renderable payload, validates it, previews it, and sends a test.
