Segments we send to Twitter do not show in their platform
Article written about why segments may not appear at a Twitter destination

The segments we send to Twitter do not show in their platform. Why?

You have not applied a mapping value to your segment. Please note that Twitter requires a human readable segment name. DO NOT use a comma in the segment name.

 

Apply the mapping value (segment name) and the audience should appear at Twitter's end after a few days.
