Software Advice offers objective insights based on verified user reviews and independent product and market research. When our advisors match you to a software provider, we may earn a referral fee.

How Software Advice ensures transparency

Software Advice lists all providers across its website—not just those that pay us—so that users can make informed purchase decisions. Users can talk to our advisors for free to receive software recommendations matching their needs. Software providers pay us for sponsored profiles to reach users interested in their products.

How Software Advice verifies reviews

Software Advice carefully verified over 2 million reviews to bring you authentic software experiences from real users. Our human moderators verify that reviewers are real people and that reviews are authentic. They use leading tech to analyze text quality and to detect plagiarism and generative AI.

Independent research methodology

Researchers at Software Advice use a mix of verified reviews, independent research, and objective methodologies to bring you selection and ranking information you can trust. While we may earn a referral fee when you visit a provider through our links or talk to an advisor, this has no influence on our research or methodology.

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.

Reasons for switching to SMS API

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:

SMS API through Esendex has been an absolute blessing to our business. We developed a CRM software and use the SMS API integration for our users to communicate, mass market, and chat with their customers. We have been a customer of Esendex since 2015 and have not had any issues with the carrier service, deliverability, customer service team, or any other pertinent parts of day to day operation. Our account manager [sensitive content hidden] has worked closely with us to get setup properly and remain 10-DLC compliant. [sensitive content hidden] has been a blessing as well, helping us understand campaign setup options and models that best suit our business model. We plan on continuing to grow with Esendex for many years to come.

Cons:

If I could ask for any change at all, it would be that we can upload our own personalized recording to play when a customer dials the SMS number. I believe there is not a free option to do this, but nonetheless it would be a nice tool for our business model. (No complaints, just a suggestion)

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.

Reasons for choosing SMS API

Pros outweighed the cons.

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.
