Anyone who regularly sends newsletters knows that webmailers and mail programmes aren't really designed for such circulars.

It's easy to take on the colour scheme of a group's website and optimise mailing for a smartphone.
All postings can be automatically posted on Facebook or Twitter. Recipients can change their details by accessing their data in the distributor. And there's a virtual chimpanzee that works with the site, providing tips about creating a newsletter.
