1What it is
When someone texts your connected business number outside an active conversation, inbound-ack-sms immediately sends a branded acknowledgment and alerts the person responsible. Inbound means the customer contacted your business first; SMS is a standard text message.
2Why it exists
An unanswered text leaves the sender unsure that the message arrived. A fast acknowledgment confirms receipt and sets a reasonable expectation for a real response.
3What you'll see happen
You will see the acknowledgment at the top of the new conversation and an internal notification that a person is waiting. The acknowledgment identifies the business and explains when a human should reply.
4What you do
Reply for real when you can. The acknowledgment buys a little time; it does not replace the conversation.
Bottom line: Every new text hears “we got it” even when your hands are full.
