More information on interactions with your Contact
In the vertical sidebar, click on the Activities tab.
Comments function as internal notes for you and your Team to refer to when necessary. For example, you may include some long notes regarding an issue or situation in a comment instead of a Custom Field.
Comments are tied to the Contact and visible across the Workspace. Anyone who views the contact details will be able to view the Comments too.
As a mentioned User, you can hit Reply on the comment to reply to the User who tagged you. This feature adds the User's name to the comment for ease of use.
Conversation Events are grouped according to their dates and sorted from newest to oldest. This way, you can chronologically run through the Events that have happened to a Contact when necessary.
