When online letter merge is the right fit
This workflow is for physical letters, not email blasts. Teams use it for recurring office correspondence, notices, donor letters, and outreach where they need personalized documents quickly and consistently.
If you need mail merge letters online with downloadable files you can print in-house, this page is built for that use case.
What teams usually do in Word
In Word, letter merge usually means template setup, source linking, field mapping, and repeated troubleshooting when data changes. It works, but is slower than it needs to be for teams running frequent letter batches.
