Yes, I am trying to find out what message i should reply if I receive email with deadlock notification.

I understand how deadlock occurs, hot to find them in logs, prevention of deadlock(ex: oqueries in order) etc.

But since the deadlock_timeout is 1s, they don't probably hang around. So post getting an alert, not sure what to respond to them

If I receive an alert for deadlock, what should I do? Like what analysis should I do? No way to find a root cause?
Under pg_locks, what I can analyse? 

If you receive an error with a deadlock, the current transaction is dead. You have to decide whether to try again.

Within the error message you find a hint which other (not aborted) transaction was involved in the deadlock. So you have all the information you need to find the culprit.

I wonder what you are writing about. A database doesn't send email notifications. That must be a feature of some application.

So you will have to deal the the application code or its developers.

Or is it a customer sending you a message that some deadlock happened on their system? Still, you have to deal with the application code or the log files of the database system.
