Reply Manager is a great platform to manage your customer service emails. You could create folders and group to organize the emails. You could assign a case to a certain support agent.Rules could be created to set your email conditions, whom to assign to and others. Overall, it's flexible and organized.
It's just sometimes I have an issue attaching PDF files in the ticket. Not sure if the file was too large.
They have the best support ever with super fast response to your submitted question. And they are very patient. Very happy with their service.
