D2C platform FanBridge says it now has 6m subscribers to its Social Digest emails, which are used to keep fans of musicians, celebrities and athletes updated on their social media doings. What’s more, 3m of those have been added in the last month along. PandoDaily explains that the emails have twice the average open rate and three times the average clickthrough rate of a regular marketing mailout from artists, buoyed by the feature that sees the emails dynamically pulling in tweets and status updates from the last 24 hours, whenever the email is opened. “We went after email because, quite frankly, it is the biggest headache for our clients and everyone knows that it’s a higher ROI channel. But its the biggest pain,” says co-founder Spencer Richardson.
