Hi Skander
Nice you are customizing an email template. I have done the same. Simply use the field you have created in your solution. Here is an example I have. Use the Square brackets around a promoted solution property.
The following activity has been assigned to you.
Business Partner process: [SolutionFormName] for BP Number: [BPNumber] Name: [Name_1_of_organization]
Region/State: [RegionState] Country: [Country_Key]
Type of Partner: [flagCustomerOrSupplier]
Please review the request and provide your comments and disposition.
Process Name: [$Process.Name]
Activity Name: [$Activity.Name]
Due Date: [$Activity.DueDate]
If you don't already have a solution field with originator/submitter, you can use a rule on the originating view, like:

Then promote Submitter

then use [Submitter] in the email template.
Hope that helps,
Sigrid
