## Questions about Magic Link + Fallback Code.

**What is the Magic Link + Fallback Code template for?**
A focused passwordless sign-in email with a primary magic link, a large six-digit fallback code, precise expiry language, and a clear not-you route. It is best suited to passwordless sign-in, cross-device login, account verification.

**Which fields can I change in Magic Link + Fallback Code?**
The public studio exposes the brand, accent, language, subject, preheader, and every visible message field. Gemini can propose structured copy changes for review. In a workspace, the template also names product, six-digit code, expiry, magic-link url, device, location, not-you url so changes can be reviewed instead of buried in raw HTML.

**Can Moosewave MCP adapt this template?**
Yes. Copy the supplied MCP brief to find transactional-magic-link-mono-code, inspect it, adapt a new private design, return the change summary and previews, and stop at a saved draft. Reading and changing a workspace still require the corresponding permissions.

**Does the public preview prove inbox or email-client compatibility?**
No. It is an illustrative browser preview for structure and responsive width. A workspace draft is where actual content, rendering checks, required fields, and pre-send review belong; the preview does not claim inbox placement or universal client rendering.
