Features of Esendex
This bulk SMS provider has established and developed a technological sophisticated SMS API infrastructure that is able to effectively distribute text messages from an email of a business to a format that can be translated into SMS to mobile users nominated by the business. The whole system uses the standard web platform that everyone is accustomed to. By sending and receiving SMS online, businesses can see and measure the effectiveness of communicating a message in a simple form that every computer and mobile user will understand and can also interact.
Esendex has the capacity to integrate SMS into apps and software, as well as the opportunity to do SMS chat using real-time SMS conversation.
This bulk SMS provider can distribute small, medium and large volumes of text messages at any one time in an efficient way. Having developed a sophisticated SMS platform known as REST API, this means that message dispatcher system is able to distribute one or more text messages when required, whether it is at a scheduled time or required to be sent immediately.
Once distribution of the text message is done, every SMS can be tracked and a status report be provided on delivery of the message. This way the business can analyse the responses received and work out the effectiveness of the message and determine any more appropriates ways to get better feedback. This way businesses can clarify and acknowledge the success of the text message. It can also provide real time updates via push notifications.
Another feature that Esendex provides is its capabilities of combining its Voice SMS, Email, Mobile and Web products in a way that will suit the business requirements for sending out a message that every computer and mobile user will know about. For examples, Esendex Voice API is able to have a company or organisation automate voice broadcasts. This is good when one needs to notify, alert or remind people about a matter promptly through broadcasting via their text to speech technology.

The schedule of charges per text message by the bulk SMS distributor is rather vague. It shows three levels of charges but does not elaborate on the difference in charges between low volumes of SMS to a high volume of SMS. It does state that there is a scaling system but does not elaborate other than to indicate ‘from just 2.5p’ Is this charge on a monthly basis and what volumes is the provider referring to?
There is no contract but not mention of a set up costs, monthly fees, price guarantee, or other charges such a keywords on shared short code, virtual mobile numbers and dedicated short code.
As shown above it mentions the automated Voice services from ‘3.5p per minute’ but no other details and the ability to take online payments via ones business website from major car providers but no details are specified.
