How to Set Up Automated Appointment Reminders
Overview
Missed appointments cost the average service shop 7 to 12 percent of scheduled revenue. A no show customer wastes a 90 minute window that could have been a paying job. Automated appointment reminders cut no show rate from 11 percent to 2 percent by sending the customer a text or email at 3 strategic points before the appointment. This guide shows you how to set up the reminder sequence inside Kaldr Tech in 20 minutes, choose the right timing, write the messages that customers actually read, and measure the no show rate improvement. Works for any service trade. You will see results in the first week of use and your dispatch board will feel visibly cleaner within 30 days.
Why This Matters
A 3 tech shop running 18 calls per day has roughly 2 no shows per day at an 11 percent no show rate. Each no show represents a lost revenue opportunity of $487 (the average ticket that slot could have produced). 2 no shows per day times 240 working days is 480 missed jobs per year, or $233,760 in lost revenue. Dropping no show rate to 2 percent recovers 80 percent of that loss, or roughly $187,000 per year. Automated reminders are the single cheapest way to recover this revenue. The reminder sequence costs roughly $15 per month in text fees on a typical shop. That is $180 per year in cost against $187,000 in recovered revenue, a 1,000x ROI. More importantly, reminder systems also reduce the inbound 'when is my tech coming' calls by 73 percent, which frees CSR capacity to book new inbound leads instead of handling status requests.

The Steps
- 1
Step 1: Set the 3 reminder touchpoints
The proven sequence is 3 touchpoints: 24 hours before the appointment, 2 hours before, and 15 minutes before (the 'on the way' notification). Each one has a different purpose. 24 hours out is a courtesy reminder that lets the customer reschedule if needed. 2 hours out is a final confirmation that prevents last minute forgetfulness. 15 minutes out is a logistics update that gives the customer time to get the dog in the garage and move the car out of the driveway. Do not add more touchpoints. More than 3 feels like spam and lowers open rates.
Pro tip: Send the 24 hour reminder at 9 AM the day before. Evening reminders get lost in personal messages.

Step 2: Write the 24 hour reminder message
The 24 hour message is a plain text or email that confirms the appointment time, the tech name if known, and a link to reschedule or cancel. Template: 'Hi Mrs. Thompson, just a reminder your appointment with Acme Plumbing is tomorrow, Thursday April 11, between 10 AM and noon. Reply YES to confirm or call 555-0198 to reschedule. Thank you.' Short, friendly, and includes a specific time window. The reply YES option is powerful because it doubles as a confirmation signal, which you can use to identify customers who are ghosting before the appointment.
Pro tip: Always use the customer's first name. Name personalization lifts response rate by 23 percent.

Step 3: Write the 2 hour reminder message
The 2 hour message is more urgent and shorter. Template: 'Hi Mrs. Thompson, your Acme Plumbing tech will arrive between 10 and noon today. Please have water turned off to the affected area and any pets secured. Text 555-0198 with questions. Thank you.' This message serves 2 purposes: final confirmation and logistics prep. Telling the customer to prep in advance (water off, pets secured, driveway clear) saves the tech 10 to 15 minutes of on site wait time, which adds up to recovered billable hours across the day.
Pro tip: Include one specific prep instruction relevant to the service type.

Step 4: Write the 15 minute on the way message
The 15 minute message is auto triggered when the tech taps Start Driving in the mobile app. Template: 'Hi Mrs. Thompson, your tech Mike is on the way and should arrive in about 15 minutes. Track his location here: [live link]. Reply STOP to opt out.' The live tracking link is the single biggest customer experience lift in modern service software. Customers who can see the tech moving toward them on a map are 4 times less likely to call the office asking where the tech is, and they leave 28 percent more 5 star reviews citing 'professional communication.'
Pro tip: Include the tech's first name so customers know who to expect at the door.

Step 5: Enable the templates in Kaldr Tech
Open Kaldr Tech, go to Settings, Notifications, and enable each of the 3 reminder types. Paste your message templates into each field, set the timing (24 hours, 2 hours, 15 minutes), and save. The system automatically applies these reminders to every scheduled appointment going forward. Test it by scheduling a test appointment for tomorrow and confirming you receive all 3 reminders at the correct times. Testing reveals any template issues, timing glitches, or missing merge fields before real customers see the messages.
Pro tip: Run the test with your own phone number. Never trust defaults without verification.

Step 6: Respect the opt out and reply handling
Every text must include a reply STOP opt out (legally required in most states). Configure Kaldr Tech to automatically remove customers who text STOP from future reminders, and to route any reply other than STOP or YES into a CSR inbox for human response. Customers sometimes reply with questions, change requests, or confirmations, and if nobody reads the replies, you lose appointments anyway. The reply inbox check is a 2 minute task twice a day, usually handled by whoever is at the CSR desk.
Pro tip: Set a keyword alert for any reply containing 'cancel', 'reschedule', or 'no' so urgent changes surface fast.

Step 7: Measure the no show rate improvement
Track no show rate weekly in Kaldr Tech reports. Before automated reminders, most shops run 8 to 12 percent no show. After 30 days of reminders, expect 2 to 4 percent. If you are still above 5 percent after 30 days, the issue is probably the reminder timing or message clarity, not the reminder system itself. Adjust the template or timing one variable at a time and measure again the next week. Continuous small adjustments typically get no show rate below 3 percent within 60 days.
Pro tip: Track 'reminders sent' versus 'confirmations received' to spot messages that are not landing.
Common Mistakes
- !Sending only one reminder 24 hours out, missing the 2 hour and 15 minute touchpoints that cut no shows in half
- !Writing long friendly messages that read like marketing emails instead of short confirmation texts customers actually scan
- !Forgetting to include the live tracking link in the on the way message, keeping the 'where is my tech' phone volume high
- !Skipping the reply inbox and missing customer reschedule requests, causing the very no shows you were trying to prevent
- !Not testing the full sequence before enabling, so the first real customer finds a broken merge field
