Hey Vikas, Shaq from the Support Engineering team here at Intercom!

Currently, Intercom does not offer the functionality to customize the subject line of email notifications for tickets. The subject line for ticket notification emails is automatically determined by either the ticket type name or the first message in the conversation. If a ticket is created through the workspace UI, the email subject will be based on the ticket type name. However, if the ticket originates from a conversation in the Messenger, the subject line of the email notification will reflect the first message sent by the end-user in the Messenger. There is no current functionality to customize this at this time. But I do see how this could be useful to users and gladly will flag this with Product team. 

Thanks! 

Can you please keep the email notification with ticket title. Because the first message will be hi, or have an issue. this is coming common for all the tickets notification email and client users are facing much difficulty in finding the ticket details using emails Could you please provide urgent fix for this?
