What's the difference between installing the add-in and purchasing a license?
Understand the difference between deploying SecureMailMerge via Integrated Apps and purchasing licenses through our licensing server.
Contents
Installing SecureMailMerge and licensing it are two separate steps. This page explains the difference and how to complete both.
Installation vs. Licensing
| Installation | Licensing | |
|---|---|---|
| What it does | Makes the add-in available in Outlook | Removes the promotional footer from emails |
| Where to do it | Microsoft 365 Admin Center (Integrated Apps) or directly in Outlook | licensing.solinventum.com |
| Who does it | IT administrator or individual user | Subscription owner or delegated admin |
| Required for use | Yes | No (free version works without a license) |
Step 1: Installation
The add-in can be installed in two ways:
Individual installation: Each user installs the add-in themselves using the Get Add-ins menu in Outlook. See our installation guide.
Admin deployment (Centralized Deployment / Integrated Apps): IT administrators can deploy the add-in to multiple users at once using Microsoft 365 Admin Center > Settings > Integrated Apps (also known as Centralized Deployment). This makes the add-in appear in Outlook automatically for selected users without them needing to install it themselves.
Important: Both installation methods only make the add-in available in Outlook. Neither method grants a commercial license. Even when deployed via Integrated Apps, users will see the promotional footer until a license is purchased and assigned separately through our licensing server.
Step 2: Licensing (optional)
To remove the promotional footer, you need to purchase and assign a license:
- Purchase a subscription at securemailmerge.com/purchase
- Assign the license to each user who needs one at licensing.solinventum.com
- The licensed user opens SecureMailMerge, and the footer disappears automatically

Common confusion
“I deployed via Integrated Apps but users don’t have a license”
Deploying through Integrated Apps only installs the add-in. Licenses must be purchased separately through our licensing server, not through Microsoft.
“The license shows ‘expired’ even though I assigned the user in Integrated Apps”
Assigning users in Integrated Apps controls who can access the add-in, not who has a commercial license. Licenses are managed at licensing.solinventum.com.
“Who needs to be licensed?”
Only users who send campaigns need a license. Users who only receive merged emails don’t need anything installed or licensed. Within a team, you can have some users on the free version and others with licenses.
