From MacRumors:
Apple Business Chat Now Available to All Zendesk Customers:
Apple and Zendesk today made Business Chat generally available for all businesses that use Zendesk Support, over two years since the service first went into beta.
Business chat is a really useful feature that lets you connect with customer support right in the Apple Messages app.
The feature takes email out of the equation and improves the entire user experience to where contacting support feels as simple as texting a friend.
I have used it to get a hold of Apple and Home Depot and it's a dream. By Zendesk integrating it, it will become easy for the numerous large and small companies to take advantage of it. The more widespread this becomes, the less often you will need to search Google for the exact page of a companies website you are looking for, fill out a web form, get tons of confirmation responses, and wait forever.
