## Demo: email ### Email.svelte ```svelte

Pick one of the pre-written emails and send it. Then open the dev email outbox to read the captured message — the styled HTML body, plain-text part, recipients, and headers.

With `{'{@attach enhance(...)}'}`

Plain HTML

Sending an attachment

Pass attachments to Mochi.email({ ... }) to send a file alongside the body. The route action reads a small pre-resized image off disk and attaches it; the outbox lists it as a 📎 chip on the captured message.

``` ### EmailForm.svelte ```svelte {#if sentSubject}

✅ Sent “{sentSubject}” to {DEMO_TO}.{isHydratable ? ' No page reload happened.' : ''}

View it in the dev outbox →

{#if isHydratable} {:else} Send another {/if}

{:else} {/if} ``` ### AttachmentForm.svelte ```svelte {#if sentFilename}

✅ Sent to {DEMO_TO} with {sentFilename} attached. No page reload happened.

View it in the dev outbox →

{:else} {/if} ``` ### PresetEmail.svelte ```svelte

A photo for you, {name}

Here's a mochi we thought you'd like — it's attached as {filename}.

Open the attachment to take a look. Reply any time.
