ClearSend: destination lists management

ClearSend was built to fill the gap of functionality that we considered essential: alphabetical sorting of destination addresses in To:, CC: and CCO: fields, as simple as they look, are common time consuming tasks. Also, keeping destination lists clean in terms of removal of duplications, control of external email deliverables or having the possibility to export them to files was considered necessary for day-to-day tasks that had to do with distribution lists coherence, or validity. Existing solutions are either complex, based on heavy extensions that need to installed separately or based on legacy approaches. ClearSend overcomes all these limitations with an state-of-art, simplistic yet powerful recreation of those table functions.
