How to Send Automated SMS to Callers and Bring in More Customers
Explore how you can use Automated SMS for missed calls, delivering coupons, and providing links and information.

Automated SMS to callers allows your business to send instant text messages triggered by call events without any manual effort.
This guide explores how you can use automated SMS for different caller scenarios like missed calls, coupon codes, customer questions and requests for information - helping you capture more customers and ensure prompt client responsiveness.
What is Automated SMS to Callers?
Automated SMS to callers means automatically sending text messages triggered by phone call interactions. Instead of waiting for your team to follow up manually, your phone system sends relevant SMS instantly based on caller behavior.
Common triggers include:
- Missed calls
- Caller request for information
- After-call feedback requests
- Sending promotions or coupon codes
Use Cases for Automated SMS to Callers
1. Follow-Up SMS After Missed Calls
If a caller tries to schedule an appointment but no one answers, an automated SMS can quickly acknowledge their attempt and make it easy for them to book online.
Example:
“Hi! We missed your call. You can schedule your appointment anytime here: [link to scheduling calendar]. We look forward to assisting you!”

This keeps the line of communication open and lets callers take action immediately, even if your team is unavailable.

2. Sending Coupon Codes to Callers
Encourage customer visits or purchases by automatically sending coupon codes via SMS as part of your call flow. This can be triggered by specific caller actions or after a call ends.
Example:
A caller presses 3 for special offers → receives an automated SMS with a coupon code:
“Thanks for your interest! Use code SAVE20 for 20% off your next purchase. Visit [website link] for details.”
Jiffy Lube successfully uses this approach, sending instant coupons via SMS to callers, which helps convert phone inquiries into in-store visits and repeat customers. Learn more about their strategy here.
This instant reward motivates callers to engage further and drives conversions.
3. Informational Hotlines Run by Volunteers
Interactive call flows can trigger automated SMS messages based on caller selections to provide helpful information instantly. Automated SMS can be an efficient and effective way to deliver information on a mass scale.
Example:
A voter hotline caller presses 1 for polling locations → immediately receives an SMS with a link to find their nearest polling place and voting hours.
This improves caller experience by delivering vital information quickly and reducing call wait times.
4. Sending Customer Feedback Surveys via SMS
Collecting feedback is vital to improving your service. After a call ends, the agent can transfer the caller to a unique call flow designed specifically to gather feedback or reviews. When transferred, the caller hears a short announcement, then receives an automated SMS with a link to a survey or review form.
Example:
After the main call, the caller is transferred to a feedback flow with a message like:
“Thank you for calling. We’d love to hear about your experience.”
Immediately afterward, they receive a text:
“Please rate your experience or leave a review here: [survey link]. Thanks for helping us improve!”
This approach encourages immediate feedback in a seamless, customer-friendly way.
