Yabber's text module supports basic messaging, MMS, Voicedrops, sending to automated lists, custom lists, Microsoft contact groups, and CRM contacts (where available). All messages are sent through your own compliant Telstra application (notging will ever route offshore).
The system is fully integrated with other modules, such as website forms, landing pages, and VoIP Telco (the only system of its kind in Australia). The system supports custom alphanumeric numbers, stop messages, email replies, and full statistics. There's also a property module (and website subsciptions block), birthday panel, and an automated RBA SMS feature.
The text module is just one of many modules and we still charge less than the dodgy and very low-performing 'lead gen' crooks.
