Threadable is a service from the company of the same name founded by Ian Baker, Nicole Aptekar, Jared Grippe, and Aaron Muszalski that’s specifically designed to help organize and retool the traditional group email mailing list experience. Rather than relying on a series of different web tools, Threadable creates threaded email conversations that can be easily managed via a simple interface.
Specifically, groups of users and subgroups within those can be added at whim, and users can mute conversations to remove themselves from threads without a fuss. In addition, Threadable’s support of webhooks allows for organizations to augment certain emails before they’re delivered to users. Threadable is currently accepting sign-ups via their website.
