For managing shared inboxes with support teams mainly. Also has great multi-channel integrations for bringing in JustCall (same devs), twilio, social inboxes, ecom order data, project management tools and more. I use it in some operations for my agency and clients and have found some great ways to implement it, especially with the fact that you can build custom api messaging integrations. Also has nice chat bot/knowledgebase features that are support focused.
