Capture Every Callback After Your Voice Campaign

The lead you lose after the call ends

A voice campaign reaches people wherever they are: on a bike, in a class, at the hospital counter. Many of them are interested but cannot respond in that moment. A day later, they remember your offer but not your number. That interest is lost unless you give them an easy way back.

Callback capture in Smart Growth AI is built into every voice campaign, so the people who want to reach you later can.

How callback capture works

Step 1: The voice call goes out

Your 30-second clip plays to your list. The system records who answered, how long each person listened, and whether they pressed 1 or 2.

Step 2: An SMS to everyone who answered

Right after the call, each person who picked up receives an automatic SMS, something like: "Thanks for listening. To know more, call us on your number." Use the number your team actually answers. This single step is what stops callbacks from slipping away.

Step 3: A message people can reply to

• Listened 25 seconds or more: an Official WhatsApp template with details and a reply button. A reply is a callback in text form.
• Listened 10 to 25 seconds: an RCS carousel with buttons to call or ask for a callback.
• Under 10 seconds: no paid follow-up beyond the thank-you SMS.

Step 4: Press-1 callers reach a person

Listeners who press 1 are connected to a live agent during the call. As a reference from our campaigns, a setting of 1,000 calls every 10 minutes connected to 5 live agents is common. Every press-1 is logged even when the conversation is short, so your team can call back if needed.

Step 5: Agents get context

Each agent receives a notification with who they spoke to and which clip that person heard. When a lead calls back or replies the next day, whoever picks up knows what the person was offered.

Step 6: Everything in one sheet

Press-1 calls, WhatsApp replies, RCS button taps and form submissions land in one Google Sheet. Each row can include name, mobile, city, interest level, listen duration and key pressed. Sort by interest and work the list.

Why it matters for cost per lead

You already paid for the call. Every person who heard it and wants to talk but cannot find you is money spent with no lead. The thank-you SMS and reply-ready WhatsApp message are small add-ons that protect what you spent on voice. In our campaigns, roughly one lead per 100 answered calls is a common baseline, and recovering even a few later callbacks makes a real difference to the final cost per lead.

Tips for better callbacks

• Put the callback number in both the clip and the SMS. Say it slowly in the clip.
• Staff the callback number during the campaign hours and the evening after.
• Keep the SMS short and in the same language as the clip.
• Check the sheet the next morning and call people who replied but were not connected.
