Set sender details
When someone on your team replies to a ticket, the customer sees a From name and a From address. Set those so replies look like they come from your company, not from Troppus.
The From address is the inbox you want customers to write back to, such as support@yourcompany.com. Set it under Admin → Domains, below your domain list.
The From name is each person's alias plus your workspace name, like Alex (Acme). Rename the workspace in Admin → Workspace. Each person can add a personal signature from their profile.
