Email Templates

Templates built for developers

Email templates in mailkube are version-controlled, variable-driven, and accessible via API. Design once, send forever, update without deploying.

How templates work

Templates live in your mailkube account and are referenced by ID at send time:

curl -X POST https://api.mailkube.com/v1/messages \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -d '{
    "to": "user@example.com",
    "from": "noreply@yourdomain.com",
    "template_id": "welcome-email",
    "variables": {
      "first_name": "Alice",
      "activation_url": "https://app.example.com/activate/abc123"
    }
  }'

Variable substitution

Templates support {{ variable_name }} syntax. Pass any key-value object at send time and variables are substituted before delivery. Missing variables render empty by default, or throw if you enable strict mode.

Versioning

Every template change creates a new version. Send against any version by ID, or always use the latest. Roll back instantly if something looks wrong.

Multi-language support

Store locale-specific template variants under the same template ID. Pass a locale field at send time and mailkube selects the right variant automatically.

Previewing

Preview any template with test variable values directly from the dashboard. Previews render as both HTML and plain text, across simulated email clients.

Plain text fallback

Every template includes an auto-generated plain text version. Or provide your own. Plain text matters for deliverability and accessibility.
