## Short answer (TL;DR)

Set up automatic SMS flows for: lead reply (under 5 min), test-drive confirmation, delivery, service reminder, ready notice, service-contract renewal, seasonal upsell and birthday. CARRUSLiNK handles triggers, segmentation and opt-out automatically. Result: 30-50% higher response rate than email and 2-3x higher conversion on follow-up.

## Why you're not using SMS as you should

- The salesperson sends SMS manually, or forgets when busy
- The workshop calls the day before, costs time and half don't answer
- Service reminders go by post, 30% never arrive and cost postage
- The customer gets 3 texts from 3 different people about the same car
- No segmentation, everyone gets the same message regardless of where they are in the journey
- No tracking, you have no idea if the SMS works or just annoys

## 7 SMS flows that work for dealerships

### 1. Lead reply within 5 minutes

When a lead comes in from AutoTrader, the website or chat, an automatic SMS goes out: 'Hi [name], thanks for your interest in [car]. I'll call you within 30 min, feel free to reply to this SMS.' Lead conversion 3-5x higher than email-only.

### 2. Test-drive confirmation + reminder

When the customer books a test drive, confirmation by SMS immediately. The day before: 'Reminder: test drive tomorrow at 2 pm on [car]. Reply NO if you need to cancel.' Reduces no-shows from 25% to under 5%.

### 3. Delivery notice + onboarding

When the car is ready for pickup: SMS with time and 'bring driver's license + registration'. Day 7 after delivery: 'How are you getting on with [car]? Remember your loan-car contract ends [date].' Better satisfaction and an upsell opportunity.

### 4. Service reminder 30 days in advance

When km or date approach the next service, the system sends an SMS with a booking link. 'Time for service on [car]. Book online here: [link]'. 40-60% book directly via the link, without reception touching the phone.

### 5. Ready notice with payment

When the mechanic is done: 'Your car is ready. Amount: DKK 4,250. Pay online: [link] or at pickup.' Customers often pay before pickup, better cash flow and no queue at the counter.

### 6. Service-contract renewal 6 months out

When the contract nears expiry: 'Your service contract expires [date]. Renew at the same price for 36 mo: [link with MitID signature]'. 70-80% renew, automatically.

### 7. Seasonal upsell

October: 'Time for winter tyres, book here: [link]'. April: 'Ready for AC service before summer? [link]'. Birthday: 'Happy birthday! 10% off your next valet.' Segment by car model, age and last service.

## What automatic SMS does for the bottom line

- **95% open rate** — SMS beats email, post and calls on open rate. Every message reaches the customer, including those who never open email.
- **3-5x higher lead conversion** — SMS reply within 5 min converts 3-5x better than email. Reaction time is the difference between sold car and lost lead.
- **60-80% online bookings** — Service reminder with booking link means the customer books themselves, without reception's time.
- **5% no-show instead of 25%** — Reminder SMS the day before reduces no-shows dramatically. Mechanics no longer stand and wait.
- **70-80% service contract renewal** — Auto-SMS 6 months before expiry renews the contract while the customer is still used to it. No more lost MRR.
- **Personal without manual time** — Every customer gets relevant messages based on car, age, last service and behaviour. The salesperson touches nothing, but the customer feels seen.

## Frequently asked questions

### How do you send automatic SMS to car customers?

Set up triggers in your CRM/platform: new lead, booking, delivery, km threshold, date threshold, season. Each trigger sends a prepared SMS with relevant link (booking, MitID, payment). CARRUSLiNK handles segmentation, personalisation and opt-out automatically. Result: 95% open rate and 3-5x higher conversion than email.

### What do automatic customer SMS cost?

At CARRUSLiNK the platform is tiered pricing from DKK 2,299/mo based on fleet size including unlimited SMS flows. SMS delivery itself typically costs DKK 0.15-0.25 per message. A dealership with 200 customers/mo typically sends 800-1,500 SMS = DKK 150-400/mo in SMS cost. Far less than the deals lost from manual follow-up.

### Do customers need to consent to SMS?

Transactional SMS (booking confirmation, ready notice) does NOT require consent, it's part of the agreement. Marketing SMS (seasonal offers, birthday, campaigns) requires explicit consent under the Marketing Practices Act. CARRUSLiNK handles consent status automatically and only sends marketing SMS to those who may receive it.

### What's a good SMS frequency without annoying customers?

Rule of thumb: max 1-2 marketing SMS/mo, plus all transactional SMS. Keep SMS short (under 160 characters) and always with clear sender and opt-out. If opt-out rate goes above 2%, send less often.

### Can you integrate SMS with Outlook, AutoTrader and DMS?

Yes. CARRUSLiNK triggers SMS flows from all relevant sources: new lead from AutoTrader, new booking in DMS, new service contract, km threshold from workshop system. The salesperson or reception doesn't need to do anything, the flow runs itself.

### Which SMS flows have the biggest impact?

In order: (1) Lead reply under 5 min, increases conversion 3-5x. (2) Service reminder with booking link, 40-60% book themselves. (3) Service-contract renewal 6 mo out, 70-80% renew. (4) Ready notice with payment link, better cash flow. Start with these 4 and you've covered 80% of the gain.
