## Reply to a contact-form message
1. Click **Inbox** and click a row with the **form** source.
2. Open the **Messages** tab in the panel that slides in.
3. Click **Reply** next to the message.

**Reply** opens a new email in your own mail app, addressed to the customer with the subject "Re: Your message". You send it from there, so it goes out from your own address and not from a yaya mailbox.

**Email** at the top of the panel opens a blank email to that customer.

## Compose a new message
Owners and editors see **Compose** in the **Inbox** header.

1. Click **Inbox** in the left rail.
2. Click **Compose**. The **New message** box opens.
3. Pick the **From** address if you have more than one mailbox.
4. Type one or more addresses in **To**. Separate them with commas.
5. Type a **Subject**, then write the message.
6. Click **Send**.

If you have no mailbox, **Compose** says "You need a mailbox to send mail." An owner sees **Create a mailbox**. An editor is asked to ask the owner. On the Free plan the box says "A paid plan includes mailboxes you can send mail from."

## Reply from a mailbox
1. Click **Inbox** and open a row where the **Source** column says **mailbox**.
2. Scroll to the **Reply** panel under the conversation.
3. Check **To** and **Subject**. A reply goes to the newest sender and the subject starts with "Re:". You can change both.
4. Write the message and click **Send**.

The message goes out from the same mailbox. "Sent to" and the address appear under the button when it lands, and the message shows in the thread.

## Format and attach
The toolbar has bold, italic, link and lists. Links must start with http://, https:// or mailto:. Pasted text arrives as plain text.

Click **Attach** to add files. You can attach up to 10 files, and 3.5 MB in total. For bigger files, share them from Files instead.

Each mailbox can send 100 emails a day.

## Send through the API
You can also send from a mailbox with the API. Send a `POST` request to `/api/tenants/<tenantId>/mailboxes/<mailboxId>/messages` with `to`, `subject` and `text` or `html`.

Add `inReplyTo` with the message id to reply. HTML is cleaned before it goes out. See [Use the REST API](/support/articles/developers/use-the-rest-api).

## Fix common problems
**"Add a real email address to send to."** The **To** field has no valid address.

**"Write a message before sending."** The body is empty.

**"This mailbox has reached today's sending limit."** It can send again tomorrow.

**"This mailbox is suspended and cannot send mail."** Email support@yaya.page.

**"Too big to email."** The attachments are over 3.5 MB together. Share the file from Files instead.

**I do not see Compose or Reply.** Your role is viewer. Ask an owner to change it.

**Customers say they did not get the reply.** Ask them to check spam. See [Emails not arriving](/support/articles/troubleshooting/emails-not-arriving).
