## Each channel gets its own message

Pick shared channels by hand, or send to a saved segment. Threadly posts a separate message in each channel, so replies and clicks stay with the right account.

## Channel lists that keep themselves current

Group partner or customer channels once. Dynamic segments follow your CRM, so a new Gold partner is included in the next send automatically.

## Every broadcast gets a next step

Add link buttons, a form, a one-click poll or a booking button. People act inside their shared channel, and you see the results live.

## Find the accounts that went quiet

Every send lists each channel with delivery status, members, clicks, reactions and replies. Find the accounts that didn’t engage and follow up.
