Send dynamic mails to customer

Send dynamic mails to customer

Hello,

we would like to send emails to customer, when they are submitting new tickets via mail.
Inside the mails there need to be dynamic text parts, so we use workflow rules + alerts.
If certain criteria matches alerts are getting sent to the customer with the customer specific text.
Problem: We trigger the workflow on ticket creation... so if a agent split a ticket the customer gets another mail. That should not be the case, how we can block this? It would be best to have a criterion to see how the ticket was created (cloned, actually new or via split). But there isnt such criterion. :(

So how we send email (with dynamic text -> so the standard notifications cannot be used) via templates ONLY if the ticket was new created and NOT splitted, cloned...?!

Regards
