Whereas Automatic Emails Send on their Own, the Other Types of Steps in a Sequence Generate Tasks for the Owner of the Sequence

Even if you include email templates or copious Notes in terms of exactly what you want to happen when a Manual Email, Call, or Task fires in a Sequence, that action will appear in the daily Tasks for whichever of your Apollo Users owns that Sequence to be manually sent or performed.

Where can I go to Ensure I Complete the Manual Tasks Assigned to me and my Teammates?

Navigate to the Tasks page in the left main menu. Here, you'll find tabs across the top of the page to view your Calls, Manual Emails, and Action Items (general Tasks in Sequences). Click the Filters button in the upper-left to expose our list of filters you can use to drill-down to tasks with specific due dates, assignees (if you want to check on other Users), and more. 

You can view the same lists of your own Tasks, ordered by date as well as priority, by navigating to the Home page in the left main menu (Click the My Assistant tab for the full view from there).
