You can now receive an hourly activity report via e-mail as an alternative to RSS. In the message section (in both Heap and Torch) you will notice a button that says "E-Mail Alert". This is a toggle. Just click on it and it will change:
You can also select a category first then click on the toggle. This allows you to select only the categories you are interested in.
You can also select individual messages. Just go to comments page and click here:
Specifically in Heap there is one more option. You can get E-Mail alerts for all messages and comments that are associated to a prospect where you are one of the managing users. Go to the dashboard and expand "Recent Prospect Activity":
No matter how many different categories, specific messages or different projects (in the case of Torch) you turn on, all the new messages and comments will be bundled together in one e-mail that you can look at once an hour.
