SMS Marketing is an increasingly popular form of marketing via mobile phones. With the rise of text messaging, SMS Marketing has become a very legitimate and viable form of communicating with a customer base.
Courier21 is a Windows based application that allows a business user to communicate with it's customers via SMS text messaging.
All you need to use Courier21 is a Windows PC that is connected to the Internet and the Courier21 software installed.
Courier21 uses the Small Mail Transport Protocol (SMTP) to deliver SMS messages. SMTP is an email protocol so the delivery of SMS messages to recipients does not cost the sender a "text message" charge. Standard messaging rates do apply to the recipients.
Courier21 requires a unique email address for each account established, whether it is a trial or subscription account. By registering for a trial account you will be assigned a unique email address to use for delivering text messages.
Since Courier21 uses the email SMTP protocol to deliver text messages each trial user should register for a trial license. When you register for a trial license you have all the functionality that a paid subscriber has because you get assigned a temporary email address. With a temporary email address you are not limited when sending text messages like an unregistered user is.
Courier21 is a Windows application that stores all its data on the subsciber's computer. All contact information and messages are stored locally so the data is literally secured at the business location and not somewhere on the Internet. Also, with the data stored locally, the user is still able to manage contacts and messages even when the Internet is not available.
Yes, there are limitations that should be mentioned. To keep messages from appearing as potential spam the following limits do exist. Only 500 messages/hour and 5000 messages/day are allowed to be delivered via Courier21.
Courier21 requires the carrier information so that it can determine the carrier address email to append to the phone number when sending the message via SMTP.
