Hello Malay,
Even though you clearly mention "I want a list of all those service tickets", I think you really mean that you want the list of sent emails. Is this correct?
If so, I would say SOST is really the plce for it.
Now if you really want the list of service tickets, then you need to share what triggers those emails and how the tickets are created from them.
Cheers,
Ian Segóbio.
