# Send Email
The **Send Email** block allows you to automatically send emails to customers during a chat flow. This is useful for sending confirmations, notifications, or follow-up information without manual effort.
***
### 🔧 When to use
Use this block when you need to:
* Share follow-up information after a conversation
* Trigger email notifications based on user actions
* Send booking or appointment confirmations
* Deliver order or payment details
***
### ⚙️ How to set up
#### 1. Add recipient(s)
* Enter email address(es) in the **To** field
* You can add multiple recipients using: `,`
**Example:**
```
user1@email.com, user2@email.com
```
***
#### 2. Set email content
* **Subject**: Enter the email title
* **Body**: Write the email content (plain text)
💡 You can include dynamic variables (if supported) to personalize the message.
***
#### 3. Configure SMTP settings
To send emails, you need to connect your email service provider via SMTP.
| Field | Description |
| --------- | ------------------------------------------------------- |
| SMTP host | Your email provider’s SMTP server (e.g. smtp.gmail.com) |
| Port | Common ports: `587` (TLS) or `465` (SSL) |
| Use TLS | Enable if your provider requires secure connection |
| Username | Your SMTP username (usually email address) |
| Password | Your SMTP password or app password |
💡 Check with your email provider for the correct SMTP configuration.
***
#### 4. Set sender information
* Define the **From** field
* Format:
```
Name
```
**Example:**
```
Support Team
```
***
#### 5. Handle delivery results
The block includes two outcomes:
* **Success**: Email sent successfully → continue the flow
* **Failed**: Email failed to send → handle errors (e.g. retry, notify agent)
***
### ⚠️ Important notes
* Make sure your SMTP credentials are correct, otherwise emails will fail to send
* Some providers require **app passwords** instead of your login password
* If the **From address does not match your SMTP account**, delivery may fail or be marked as spam
* Always test your setup before using it in a live flow
