Go Document Merge

Go Document Merge is an automated document creation add-on for Google Workspace.

Typical quotas cited on site are about 2000 docs/day for normal Gmail and about 4000/day for Google Workspace. Marketplace listing describes it as 100% free. Built for teams that need bulk personalized contracts, letters, certificates, and other Docs without leaving Google Workspace.
