Email Templates

What it does

The mailkube template engine lets you define email layouts once and reuse them across your entire application. Define your structure, brand, and content blocks in a single place — then pass dynamic variables at send time.

No more assembling HTML strings in your application code. No more copy-pasted email layouts drifting out of sync. Templates live in mailkube, versioned and preview-ready.

Key benefits

• Variable substitution — Pass dynamic data at send time: names, links, amounts, order IDs. Any field in your template can be a variable.
• Live preview — See exactly how your email renders before a single message is sent. Test with real variable values.
• Version history — Every template change is versioned. Roll back to a previous version safely without redeploying your application.
• Multi-locale ready — One template per locale, sharing the same variable contract. Ship a French version alongside your English one without duplicating logic.

Getting started

1. Create a template in your dashboard or via the API
2. Give it a unique slug (e.g. order-shipped)
3. Reference it by slug when sending — pass your variables in the data object
4. Preview before you ship

See the API Reference for the full template object schema and the data payload format.
