iPost supports both SMS (Short Messaging Service) and MMS (Multimedia Messaging Service) with our Mobile option. SMS is text only while MMS allows for media files to be included with the mobile message.

Help! What should my message be?

The main thing to remember about your mobile messages is that they should be short and to the point. SMS content is limited to 160 characters which includes all legal disclaimers and an opt out. MMS content can go up to 1600 characters, but you will start to lose your consumers with long winded messages. Besides that, be yourself and be sure to include the voice of your brand. Here are some best practices to keep in mind when creating your mobile content.

  • Keep content brief and to the point
  • Include all legal disclaimers (if applicable)
  • Supply a way to unsubscribe
  • User Personalization
  • Watch the frequency of the messaging
  • Try not to use common text abbreviations
