Hi Andrew!

So generally, I think most integrations are built by the companies that are being integrated with, as they know their own environment best. We do have some tools that can make that easier: Zendesk Integration Services

In the meantime, while there aren't any official direct integrations between Zendesk and Reddit, there are a number of third-party integration services that appear to be able to integrate the two systems. Generally these will be using the APIs of each system, so probably a bit less "hacky" than using a script to send an email (no judgement though on that). Some examples include Zapier, tray.io, Cloudpipes, and integromat.

Hope that helps!
