Prompt response from Thristan Luna. Luna was very clear and effective. Thank you.

I used YAMM for a few music releases. It was really easy to use and very effective at integrating my releases out to industry. I've since changed tactics and no longer require it but highly recommend. Also, I always found their customer support timely and very helpful
By Brendan M.
The fastest and most effective support I've seen so far. Got an email back almost instantly after submitting my ticket, and would get replies in minutes. I've got everything I needed solved in about half an hour (refund for a wrong purchase included!), and all this on a Sunday night! Great experience all around
