Our customer communications team have become a contender for top slot with their metric: 70 million customer e-newsletters distributed in the year.

That total covers their entire client base and various geographies. Their largest single distribution is to a customer base of 1.4 million users. The team manage all aspects of content, design and distribution, plus analytics.

That's not random spam you understand, that's 70 million e-newsletters to customers who have proactively signed up to stay in touch with different product or audience information - and therefore jump through all the privacy and data protection compliance necessary.

Often this activity is one element of broader community building programs, designed to drive usage and increase interaction within the community, informing customers of new tools, features available to them.
