On several occasions, we have had the need to ask for help from the Adobe Target support team, and I must say that they have provided us with an excellent experience, as they take care of solving the problems quickly and with high precision.
Adobe rarely responds before the 3rd or 4th time you attempt to get up with them, and when they do there are many delays, transfers, that typically lead to us solving the issue ourselves in the meantime before they can.
Customer service was friendly and very reachable. However, they weren't always knowledgeable in helping us solve our problems. Also, because of our contract we were limited in the number of support hours and help we could receive.
They have some idea of how to debug problems, but much of the time was spent on understanding hierarchical structure of the support team because escalation often slow.
Adobe Test and Target is an A/B, multi-variate testing platform which Adobe acquired as part of the Omniture platform in 2009. It is now part of the Adobe Marketing Cloud. It offers tight integration with Adobe analytics and content management products.
