Expion has appointed Capella PR for the UK launch of its social media management software.

Capella's programme will align Expion with the hot issues in social media management, explore the effectiveness of high profile UK brands’ social media campaigns and also include a press office covering media relations, speaker engagements and rapid response.

The agency's campaign will kick off at the forthcoming Social Media World Forum in London on 18 March, where it will raise awareness of Expion among social media and marketing managers within brands and digital agencies.
