Customer service is very responsive and provides thorough explanations.

Pros

Esendex ensures the address data managed by my organization meets postal standards.

Cons

We had a situation when a user inadvertently enabled the address verification process multiple times in a single day. It resulted in higher than average fees. Ideally, the application would allow users to set a maximum number of transactions per day. That would help eliminate unintentional charges.

Good experience with customer service. The API is simple to use.

Pros

Simple interface. Ease of use. Good customer service.

Cons

Originally the account management website during the transition from CDYNE to Esendex was a bit confusing, but I think that has bee corrected now.

[Clickatell](https://www.capterra.com/p/175976/Clickatell-Touch/)

They had terrible customer service. One evening I called Clickatell about an online billing issue, and the customer service rep seemed to be on an online roll playing game and was a bit upset I was disturbing him. I immediately switched to CDYNE.

Pros

Fairly easy to use. Clients understand how to use the product.

Cons

It is fairly expensive. The cost fluctuates up and down, but not always in a linear fashion to number of notifications. The price should go down as the number of notifications go up, but sometimes it is the opposite. For example, we were charged .05 per notification for 13,561 uses, but then .0525 for 23,391 uses.

Pros outweighed the cons.
