Subject: Shared reporting is on the Business plan
Preview: See response times for your whole team in one place

Hi Priya,

Your team answered 1,200 conversations last month across 8 people.

Shared reporting shows each teammate's first response time, open
conversations and busiest hours on one page, so you can spot a queue
before customers do.

It's included in Business at $25 per seat per month, and you can try
it free for 14 days without changing your plan.

If you're happy where you are, you don't need to do anything.
