Ease of use

Functionality

Pros:

This product does what it says. We are able to deliver notifications to our users with great speed and in large numbers. As a developer, I can say that it is very easy to add to whatever system you're working with. The documentation is very helpful in this regard too. When there have been issues, the customer service has been excellent. The team at Cdyne has always been quick to respond and assist with any issues.

Cons:

I would like to be able to send in additional identifying information for my notifications so that I am able to group them on my end when reviewing the logged data that we receive back from Cdyne. This may be in there by now though and I've missed it...

Functionality

Pros:

Easy to use and get started with. Developed an app quickly to utilize the many features of the API. We also liked the ability to host a short code and they made it easy to implement.

Cons:

The pricing is not as good as some of the other companies in this space. My customers have many options now and we must stay competitive against the larger players.

Reasons for choosing SMS API

At the time, Cdyne was one of the only companies that offered MMS and short code hosting. Most have now caught up with these features.

Thank you Steven for this review! We greatly appreciate your business and look forward to continuously providing you with quality SMS API services.

Pros:

C# API support. No monthly usage requirements.

I'd really like a carrier disconnect list, so I can opt out numbers that the carrier will be releasing to the available number queue. It is super convenient and offered by other providers. ex. Vibes and Open Market

Reasons for choosing SMS API

We don't generate the volume required by some gateways. SMS Notify is a good middle ground.
