## What you can do

Send email through your connected SMTP mail service.

This reference includes **2 actions**. A connection for workflow actions and a customer-facing Line serve different purposes: connecting an app does not automatically create an Inbox channel.

## Connect your account

1. Open **App Connections** in the organization where you will build the workflow.
2. Choose the SMTP email connection that matches your task.
3. Complete the provider’s sign-in or the protected connection form. Enter credentials only in that form.
4. Return to your workflow, add the action, and select the connected account.
5. Choose a test resource and check a small operation before enabling the workflow.

### Choose a compatible connection

Actions declare these connection types. Check the account selector on the individual action; some actions support only a subset.

- `smtp`

## Available actions

| Action | Use it to |
| --- | --- |
| [SMTP: Send Email](/nodes/smtp-sendemail/) | Send a plain text or HTML email via any SMTP server, with optional file attachment. Supports multiple recipients (comma-separated To, CC, BCC), Reply-To, HTML + plain text bodies. Attachment accepts a URL, a data URI (data:image/png;base64,...), or raw Base64 — so you can directly pass the result of nodes like QR Code Generator. |
| [SMTP: Verify Connection](/nodes/smtp-verifyconnection/) | Test and verify the SMTP connection without sending an email. Use this for health checks and to confirm the mail server is reachable and credentials are valid. |

## Work with events

Some services offer separate automation connections or event-retrieval actions. When available, configure the event source and workflow trigger together. A successful account connection alone does not mean that events are being delivered. Test with a new event and check Workflow Activity.

## Common problems

- **No account in the selector:** confirm the organization, service, and connection type.
- **Access denied:** verify access to the exact resource, not just a successful sign-in.
- **No events:** check the automation settings, event type, and trigger configuration.
- **Duplicate actions:** inspect the destination before retrying a failed or timed-out run.
- **Provider restrictions:** available actions, quotas, and permissions depend on the connected provider account.
