# 11.17 Activity: Send Email

Needs a contact with an email address.

**Message type:**

- **Template:** pick an **Email template** ([10.4](/docs/email-templates/)). Its placeholders are filled from the contact.
- **Custom message:** write a **Subject** and **Body** in the editor, without a saved template. **Insert placeholder** adds contact or system data such as `{{ContactFullName}}`, or trigger data such as `{{Trigger.…}}` on message and store triggers. The available placeholders are listed in [10.4](/docs/email-templates/).

**Channel (which mailbox sends it):**

- **Auto:** the mailbox the inbound email arrived on (for **Message Received via Email**), or the email campaign's Reply-To mailbox (for **Triggered from Broadcast**), otherwise the mailbox assigned to the contact's owner.
- **Specific mailbox:** always send from the **Reply-to mailbox** you choose. Use this for every trigger other than Message Received via Email, so the step never depends on the contact having an owner.

**Pitfalls:**

- Workflow emails go out through a **Reply-To Mailbox's** SMTP settings, not through an Outbound Mail Server. The mailbox needs outgoing settings ([10.2](/docs/reply-to-mailboxes-contact-communication/)).
- Fails with "Contact does not have an email address", "No active email mailbox is available…" (Auto found no mailbox), or "Selected mailbox has incomplete SMTP settings".
