# Sender setup

This document explains how to create and manage sender profiles in Engage Studio. Sender profiles define the sender identity and unsubscribe settings used in your marketing emails. Configuring this correctly ensures brand consistency, compliance with email standards, and improved deliverability.

## Accessing Sender Profiles

1. From the left navigation menu in Engage Studio, click **Sending Configurations**.
2. Select the **Sender Profiles** tab.
3. Click **Create new** to open the sender profile setup form.

## Creating a Sender Profile

The sender profile creation wizard includes two main tabs:

### 1 Details Tab – Sender Identity

| Field | Description |
|  --- | --- |
| Name | Internal name used to identify the sender profile (e.g., "TD Test") |
| Domain of from address | Select from previously verified domains configured under Domain Settings |
| From address | Local part of the sender email address (e.g., `info` to form `info@yourdomain.com`) |
| From display name | The name shown in the recipient's inbox |
| Default reply-to address | Optional address for replies |
| Default reply-to display name | Optional name shown for the reply-to field |

### 2. Unsubscribe Header Tab – Compliance Settings

To support List-Unsubscribe features and remain compliant with global email regulations (e.g., CAN-SPAM, GDPR), configure unsubscribe settings here.

| Field | Description |
|  --- | --- |
| URL | HTTPS link to your unsubscribe landing page.
Accessible in the content editor via `{{sender.unsubscribe_url}}`.
Example:  `https://your_unsubscribe_url/unsubscribe.html?email={{profile.email | url_encode }}` |
| Mail-to email | Email address that receives unsubscribe requests when HTTP fails.
Accessible in the content editor via `{{sender.unsubscribe_email}}`. |
| Mail-to subject | Optional subject line for the unsubscribe email. |


You can enable or disable **one-click unsubscribe** functionality via toggle. When enabled, it adds List-Unsubscribe headers to your email.

## Managing Sender Profiles

Once sender profiles are created:

* You can edit or delete them from the **Sender Profiles** list view.
* Sender profiles cannot be deleted if they are linked to active campaigns.
* Multiple profiles can be created per domain to support different business units or brands.


## Tips about Unsubscribe Header

### What is a List-Unsubscribe Header?

A list-unsubscribe header is an email header field that provides recipients with an easy way to opt out of future emails. It typically appears as an "Unsubscribe" link or button in the email client's interface, separate from the email content.

### Why is it Important?

Starting February 2024, Google and Yahoo began requiring that all bulk marketing emails support a one-click list-unsubscribe header. This requirement helps ensure better user experience, improved inbox placement, and compliance with modern email regulations.

## Setting Up Unsubscribe in Engage Studio

### Option 1: Use Two-Steps Unsubscribe URL

This option allows for a manual opt-out process through a landing page.

**Steps:**

1. Create and publish an opt-out landing page
  * **Current Limitation:** Landing page hosting feature will be coming later. For now, use 3rd party service capabilities such OneTrust, etc.
2. Include the link in the email body and in the **Unsubscribe URL** field of the sender profile


**Examples:**

* `mailto:unsub@example.com`
* `https://example.com/unsubscribe?email={{profile.email | url_encode}}&type=mailmagazine`
* Or use both


Include the recipient’s email (`{{profile.emailemail}}`) in the URL to uniquely identify them.

### Option 2: Use a One-click Unsubscribe URL

This option is designed for users with their own custom unsubscribe endpoint.

**Requirements:**

* The URL must handle `POST` unsubscribe requests
* It must begin with `https://`
* POST requests must not rely on cookies


**Steps:**

1. Navigate to the **Sender Configuration > Unsubscribe Header** section
2. Enable the toggle for List-Unsubscribe Header
3. Enter your one-click `POST` unsubscribe endpoint URL
4. Optionally add a `mailto:` fallback address


**Example header generated:**

* `List-Unsubscribe-Post: List-Unsubscribe=One-Click List-Unsubscribe: <mailto:unsub@example.com>, <https://your-unsubscribe-post-endpoint.com?email={{email}}>`


**Current Limigation:** Engage Studio currently does not provide a built-in POST endpoint. Customers must manage their own with using 3rd party services until this functionality is released.
