A practical first project
First generate drafts only and send nothing automatically. Outlook is not yet supported.
Two ideas for your working day
Discuss customer feedback directly with your team
Assign emails for a customer project to a channel and clarify questions through private comments on the relevant thread. For example, coordinate a complaint response with sales before it goes to the customer. During setup, check which team members may see the project context.
Upstream: email featuresCheck a follow-up draft against other conversation threads
When Upstream prepares a follow-up email, check whether a reply or commitment already exists in another thread with the same recipients. The provider says such threads are considered when drafting. Use this support especially for parallel proposal and appointment discussions, and confirm the draft yourself before sending.
