From one backorder notice to the annual price-list run across every account.
Every feature, on both plans. Choose your plan →
Use it free with a promotional footer, or remove the footer with a license.
Your customer list and documents are processed on your computer inside Outlook.
Finished emails are sent through your own Microsoft 365 mailbox. Nothing is uploaded to our servers, and every sent message is in the account manager's Sent Items for the next call.
No open pixels or click tracking. A price-list email is business correspondence, not marketing. The license check sends your mailbox address, the product name and a timestamp, never your customer data.

Answers before the first price-list run.
Visit the Help Center →Yes. Each account manager installs the add-in in their own Outlook and sends their own batch, from their own customer sheet or a copy of the master list with only their accounts. Everyone can start with the free version. A paid license covers one sending mailbox, so buy one per account manager and assign them on the licensing server.
See how to assign licenses →Yes. Put one order line per row with the same customer address, and choose many-to-one mode. Each customer gets a single email with a table of their lines, and the attachments from those rows are combined.
Set up a many-to-one mail merge →SecureMailMerge adds no size cap of its own. Microsoft 365 limits a message to 35 MB by default, including attachments, and administrators can raise this to 150 MB. Attachments grow by about a third when sent, so share very large catalogues as a OneDrive or SharePoint link.
Check the size and sending limits →Yes, with Send As permission for the shared address. Each account manager installs the add-in on their own mailbox and picks orders@ or sales@ in the "From" field. Sent messages are saved in their own Sent Items folder, and replies go to the shared mailbox. Running the add-in directly inside a shared mailbox is not supported.
See shared mailbox setup →After each campaign, download the send report as an Excel file. It lists every customer row with its status, the attachments included and when Microsoft 365 accepted the message. It records submission, not inbox delivery, and SecureMailMerge does not track opens.
See the send report →Each account manager needs a Microsoft 365 work or school account. New Outlook, classic Outlook, Outlook for Mac and Outlook on the web are supported. Your organization may require administrator approval for add-ins, so IT can review the permissions and deployment guidance before anyone installs.
