## Overview

Beyond text, you can enrich a conversation with **attachments** (files, images, documents), **voice
messages** recorded on the spot, **emojis** and **reactions** to messages. The availability of each
feature depends on the channel: WhatsApp, for instance, supports most of them; other channels may vary.

## Prerequisites

- An open conversation in an inbox that supports the feature you want.
- For media, respect the channel's size and format limits.

## Step by step

1. **Attachments**: in the reply box, use the attach button to pick files from your computer (or drag and
   drop). Add a caption if you like and send.
2. **Voice message**: use the microphone button to record; stop when done and send the audio.
3. **Emoji**: open the emoji picker to add one to the reply text.
4. **Reactions**: hover over a message and choose a reaction (when the channel supports it) — handy to
   confirm receipt or signal agreement without sending a new message.
5. Check the preview before sending.

## Settings & options

- **Attachment types**: images, videos, audio, documents and other formats the channel accepts.
- **Captions**: many media types accept text alongside them.
- **Reactions**: depend on the source channel; not all support them.
- **Reuse files**: when the Media module is available, you can re-send already-saved files without
  uploading again.

## Use cases

- Send a receipt, a PDF manual or an illustrative image.
- Reply quickly with audio when writing it out would take too long.
- React to a customer's message to confirm receipt without cluttering the conversation.

## Tips, limits & best practices

- Respect the channel's **size/format limits** — large files may be rejected.
- Prefer PDF for documents and common image formats for photos.
- Use audio sparingly; many customers prefer text they can reread.

## Troubleshooting

- **The attachment failed**: check the size and format accepted by the channel and try again.
- **I can't react to a message**: the channel may not support reactions.
- **The audio didn't record**: check the browser's microphone permission.
