I specifically use Zendesk to use their support ticket system. I am not interested in live chat. I also like their CRM. Right now, you don't provide those features, right?
This may be out of your depth but I'd love to see a provider that supports Discord.
eg. Tagging a bot in a #support channel for help, being able to reply from it, and being able to cross post announcements from such a bot alongside twitter/facebook.
I can only see live chat. Am I missing something?
