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.
From the left navigation menu in Engage Studio, click Sending Configurations.
Select the Sender Profiles tab.
Click Create new to open the sender profile setup form.
The sender profile creation wizard includes two main tabs:
| 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 |
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.
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.
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.
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.
This option allows for a manual opt-out process through a landing page.
Steps:
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.
Include the link in the email body and in the Unsubscribe URL field of the sender profile
Examples:
mailto:unsub@example.comhttps://example.com/unsubscribe?email={{profile.email | url_encode}}&type=mailmagazineOr use both
Include the recipient’s email ({{profile.emailemail}}) in the URL to uniquely identify them.
This option is designed for users with their own custom unsubscribe endpoint.
Requirements:
The URL must handle
POSTunsubscribe requestsIt must begin with
https://POST requests must not rely on cookies
Steps:
Navigate to the Sender Configuration > Unsubscribe Header section
Enable the toggle for List-Unsubscribe Header
Enter your one-click
POSTunsubscribe endpoint URLOptionally 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.
