We just moved to JSM from Kayako, and we are getting constant feedback from all customers that the lack of comment history makes following issues almost impossible without logging into the portal.  Our customers live in email, not the portal. Please add this functionality, or at least a variable for the previous comment that we can add to notifications ASAP.

needed ASAP

Dear Atlassian Team - This functionality is critical.  

Please.

Perhaps this very basic feature will be added by the time the Chicago Cubs win the World Series again.

This is a very important piece of functionality. We consistently have customers complaining about not getting a full comment history in email notifications and having to access the portal to see the full context.

Dear Atlassian Team - this is essential and we are getting complaints from customers who can't see comment history.

It is doable in separate email but in notification when comment is added - it doesn't work.

Please increase priority of this!

This is so essential EVERY other ticketing system has this feature by default. Again Atlassian miss this and expect us to wait 20 years for it to be implemented. This is a complete joke and I cannot understand how you've been allowed to get away with this so much. 

And you want to increase all prices by 5-10%?

For what - If I had a choice I would move away tomorrow.

Please, this would be the best thing ever if Jira implements it!

More variables for email notifications are very much needed for JSM.

Please look to implement the ability for customers to see all public comments on email notifications soon!
