Kia Ora,
I have seen this elsewhere and am hoping Jira has something similar...
When a user sends an email, or submits a ticket through the SD portal, that the email acknowledgement email would list possible solutions, e.g....
"Thank you for your email.
Based on the issue you describe... try these:
1.
2.
...
If the suggested solutions have not helped &/or you just need a real person, please click here to submit your ticket."
I guess a ticket would need to be created so that it could be tracked to see who resolved w/ self help and who needed a human.
Appreciate your time and assistance.
