In the forum update emails sent by TradingQnA.com,
the prefix " [Trading Q&A by Zerodha - All your queries on trading and markets answered] "
- consumes all the space in most email clients.
- hides the actual category/title of the topic.
Thus making it very hard to visually search, find and read desired email. 
Would it be possible to configure TradingQnA.com (Discourse?)
to set the subject of its outgoing forum emails to something minimal like
-
" TradingQ&A - [Category] - [Title] "
or ideally more space to the topic title as follows…
-
" [Category] - [Title] "
(as we anyway know the sender is TradingQ&A)
