Use Mac-Compatible Mail Merge Alternatives

Switch from Windows-only add-ins to third-party tools or scripts specifically developed for macOS.

Check the add-in developer's website

Visit the official website of your current add-in provider to see if they have recently released a Mac-compatible version of their software.

Explore specialized Mac add-ins

Search the Microsoft AppSource store or trusted third-party vendors for mail merge software that specifically advertises support for Word for Mac and email attachments.

Utilize automation workflows

Consider using alternative automation tools, such as cloud-based mail merge services or AppleScript workflows, that integrate seamlessly with Office for Mac to attach files during the merge process.
