Template variables

Use {{mustache}} syntax anywhere in the subject or body: 
Subject: Welcome to {{business_name}}, {{first_name}}!

Body:
Hi {{first_name}},

Thanks for signing up — we're excited to have you. If you need help, just reply to this email.

Cheers,
{{sender_name}}
ShingleAI extracts every {{variable}} automatically. There’s no separate step to declare them — just use them where you want them filled in.

​
What the preview shows

The template detail page has a Preview tab that lists every extracted variable. You can fill sample values and see the rendered subject and body update live.

​
Validation

ShingleAI validates the subject and body for Mustache syntax errors on save — for example, an unclosed {{ or a dangling }}. You cannot save a template whose syntax is invalid.
Variables that aren’t provided at send time render as empty strings — Mustache silently skips them. If a variable is truly required, enforce that in the automation or agent that calls the template, not in the template itself.

​
Active vs. archived

Every template has an active or archived state. Archived templates don’t appear in the automation/agent picker but remain in the list for reference and reactivation. This is a soft state — archiving does not delete history.
