Review for Mail Merge by Paddy Landau
Rated 5 out of 5 stars
Some products do just one thing, but they do it perfectly.
I am glad to say that the latest version (3.2.0) is one of those products, with the developer having solved the original restrictions.
Mail Merge is simple yet flexible, and performs exactly as expected.
Thank you for this incredibly useful add-on.
