To send bulk SMS messages from your email client or server all you need to do is connect to the Clickatell gateway by using our SMTP (Simple Mail Transfer Protocol) application programming interface.

Registering for SMTP and connecting to our gateway is completely free. You only pay for the messages that you send.

The cost of this varies depending on the volume purchased and the destination you intend sending to. We have a convenient calculator to help you work out your message costs.

Once you have registered we will also give you 10 free message credits with which to test your connection. Sending messages is as simple as typing a plain text message into you email client and pressing send.

• Send messages longer than 160 characters
• Send contacts using our Vcard and Vcal converters
• Change the Sender ID
• Request a delivery acknowledgement
• Send messages using plain text, flash, binary (ring-tones and logos) and Unicode ( Arabic, Chinese etc)
