New research suggests that more than half of UK businesses deem their email strategy ‘basic’ or ‘non-existent’ despite the expanding consumer-driven demand for mobile optimised content. The report, from Econsultancy and Adestra, found that 39% of businesses confessed to having a basic email strategy and a further 22% said their strategy was non-existent – even though many of the participating businesses noted that more than 50% of their email marketing messages are opened via mobile devices.
