Adding request participant as the assignee of the issue

[Maneesha Ratnadiwakara]

I have a function where issues are created via email and salesperson is added in CC field in this email, who will be added as a request participant in the jira issue. 

I also want to add an automation to make this salesperson as the issue assignee. 

Or is there another way to add the CC mail address as the issue assignee when the issue is created?

If the email address that creates the ticket is always the same for that sales person to be the assignee you could also do an automation based on the reporter that.
BUT that being said I really came here to warn that when you have a user as the assignee and a request participant you should check your global JSM notification settings under admin cog>products>JSM>configuration

Because your user will be both an agent and a customer making notifications wonky for them.
You can decide what the best fit is for your situation and update this setting.


Then you can tweak the customer notifications and the agent notifications on the project level to avoid confusion ( which will mostly be the email link on notifications sometimes taking them to the portal - customer notification or the link sometimes taking them to the agent / backend view)

Is there a way to add the CCed email as the assignee without using automations?

No email tickets you only get:
the summary = subject line
the description = body of email
the reporter= sender of email
request participants = CC'ed people
