Twaitter could be included in twitter marketing tool based on my opinion because they have some useful features such as:
- Schedule: Schedule your twitter messages
- Recurring: Set your twitter messages to send on recurring basis: daily, weekly, monthly, yearly.
- Twitter Calendar: Manage your scheduled messages (Twaits) with our powerful calendar tool that works just like your Outlook calendar.
- Translation: Translate your tweets into any language with the click of a button. Do you follow tweeple that post in foreign languages? …easily translate any tweet into a language you understand
- Feeds: Register your blog or business RSS feed with twaitter and have your new posts automatically sent to twitter. (coming soon)
- Schedule in Mass: Have a lot to say and a lot to schedule? Upload a file with your messages in our file format and we’ll be happy to schedule all the twaits for you. (Coming Soon) *subject to Twitter message sending limits
