Can I see who replied to a broadcast?

A customer’s reply arrives as a normal message in their own chat, under the template you sent, so whoever answers sees the context. Haiya does not mark which broadcast a reply came from and does not count replies; the results show delivered, read and failed. More on broadcasts in Haiya.

How many people can I send to?

Broadcast recipients are counted per calendar month, and the number depends on your plan. See the plans.
