> **For AI agents:** the complete documentation index is at [llms.txt](/llms.txt). Append `.md` to any page URL for its markdown version.

Start a message from the **New message** button at the top of the rail, the <kbd>c</kbd>
key, the <kbd>⌘</kbd><kbd>K</kbd> palette, or **Reply** on any message.

## Write and send

Add people in **To** (and **Cc** / **Bcc** when you need them), a subject, and your
message, then press **Send** or <kbd>⌘</kbd><kbd>↵</kbd>. The recipient fields suggest
people you've written to before as you type.

Mail goes out over your account's own mail server, and a copy lands in your **Sent**
folder, so it reads the same in every app.

<Note>
Messages are plain text today. Attachments and formatting are next.
</Note>

## Send later

To hold a message for a better time, press **Schedule** in the compose bar. A row of
times opens above it:

- **Later today** and **This evening**
- **Tomorrow AM** and **Tomorrow PM**
- **This weekend** and **Next week**
- **Pick a time…** for any date and time you set

Choose one and the **Send** button becomes **Schedule · your time**. Press it to queue the
message, or press the caret next to it to change the time. To send right away instead,
press **Unschedule**.

<Info>
Scheduled mail is sent by Mailhopper's servers, so it goes out on time even if your
computer is asleep or the tab is closed. Preset times use your own time zone.
</Info>

## Undo a send

Every send waits a few seconds before it leaves, so you have a moment to catch a mistake.
Right after you send, a bar appears with an **Undo** button — press it (or <kbd>Z</kbd>)
and the message reopens for editing.

Choose how long the window lasts, or turn it off, under **Settings → Inbox → Undo send**
(off, 5, 10, 20, or 30 seconds).

## Manage scheduled messages

Open **Scheduled** in the rail to see everything waiting to go out. On any message:

| Action | What it does |
|--------|--------------|
| Edit | Reopens it in compose so you can change anything. |
| Send now | Sends it immediately instead of waiting. |
| Cancel | Takes it out of the queue and reopens it as a draft. |

If a scheduled message can't go out at its time (an expired mailbox sign-in, say),
Mailhopper keeps it, marks it in **Scheduled**, and emails you. Nothing is sent by
surprise, and nothing is lost.

<Tip>
Send later and Undo send work with both password and Gmail accounts.
