Here’s my take on how to use Asana as a helpdesk platform with bi-directional emails from and to externals who don’t have an Asana account. It has removed so much friction from our support comms by pulling the email convo into the actual work packages.
You do need some automation set up. But no expensive licenses for full-blown support or CRM suites like Zendesk or Hubspot etc.
Hope, you can find a couple of ideas to adopt. Let me know, if sth is missing for your particular use cases.
