Timely response and exceptionally polite. Thank you. I've been using YAMM for 5 years and couldn't live without it :)

Been using YAMM for a while now, but had never needed support before. They were very helpful and quick to respond. It's 4 instead of 5 stars only because I've had a few instances where it incorrectly calculated the number or email sends I had remaining in my quota and ended up with a blocked email for 24 hours. Best to break up your lists manually into chunks of 1k or so to avoid this happening to you.

Product works great. Super simple to use. Customer service was exceptional. Love this tool and team.
By Scot S.
Perfect customer experience, quick, warm, efficient. We’ve just switched 4 individual accounts to a Team one in less than couple of hours with all the refunds for the unused license periods. - All the added features (Polls, Filtered lists) help a lot for RSVPs activities. - EU invoicing. Happy “4yrs old” customer

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.
