YAMM is intuitive and makes so many processes easier. The interface is well designed and the tracking reports are excellent in the school setting in which I use it. I highly recommend this product.

I was having trouble doing YetAnotherMailMerge (YAMM) and contacted the YAMM team. They got back to me sooner than I expected, asked questions to clarify what my issue was and then offered suggestions and following up with me by email to ensure the issue was resolved (which it was). Great customer service!
