YAMM is a very good tool. A lot more cost-effective than other solutions I was looking at and just as useful. Also it's not just a faceless app. If you have any troubles the guys are very supportive and helpful.

YAMM has enabled me to personally connect with so many more people. Emails that would normally get overlooked GET ATTENTION. It's the best. Plus, the Customer Service is fantastic. So fast, and so helpful!

Many thanks to the assistance team. The image of a dynamic QR Code is now perfectly integrated into my mailing (gmail). Merci à l'équipe d'assistance pour avoir résolu mon problème !

I'm new to YAMM, and was quite impressed. I've used a few mail merge programs in the past, nothing quite as easy and convenient as YAMM. The feedback report is great. My 350 messages were all delivered without problem, as far as I can tell. Strongly recommend YAMM if it meets your mailing needs. It certainly met mine.
