Each day, team members receive an email asking “What did you accomplish today?” (you can change or add questions). The next morning, Daily Pulse will send everyone a summary so the team has an idea of what’s been done and what still needs work.
Users can then sign in to the service to comment and discuss others’ accomplishments.

Does this allow in-email response?
