What text messages should an auto repair shop send to customers?

Five core types cover almost everything. Appointment confirmation when booked plus a 24-hour reminder. A 'we're working on your car' update when the tech starts (customers love it even though it's not required). An estimate approval link they can act on from their phone. A 'your car is ready' message with a pickup window. And a review request two hours after pickup. That's the entire core stack. Everything else is optional.

What's the typical SMS open rate compared to email and voicemail?

Around 95% open rate with most replies coming inside 90 seconds. Email opens at maybe 20%, voicemail at maybe 30%. For an industry where the customer is almost always driving, waiting, or between tasks, text is the only channel that reliably reaches them. That's why mishandling it costs so much. Mass blasts, multi-segment messages, and shortened URLs throw away the best channel you have.

How long should an auto shop's text messages be?

Under 160 characters whenever possible. Anything longer gets segmented into multi-part SMS, raising costs and lowering read rates. Open with your shop name. Customers don't save your number, so 'Smith's Auto:' in the first two words tells them who it's from in half a second. Get to the action in one line. End with an opt-out on anything promotional. 'Your estimate is ready: [link]' beats any clever copy.

Should I text customers from my personal cell phone or use an SMS platform?

Use a real SMS platform that belongs to the shop, never a personal cell. When an advisor leaves, conversation history leaves with them, you lose the audit trail, you can't hand the customer to a new person cleanly, and there's no way to enforce TCPA compliance. The cost difference between a real SMS platform and a stranded customer relationship isn't close.

What SMS metrics should an auto shop track?

Four numbers. Delivery rate should be 98% or higher; if it's lower, your 10-digit number is probably unregistered under A2P 10DLC or filtered by carriers. Response rate on appointment confirmations should land at 50–70%. Click rate on estimate and review links is healthy at 20–40% where your platform tracks it. Opt-out rate on promotional messages should stay under 2%. If it's higher, you're over-messaging your list. Delivery and opt-out show up on any SMS platform; link clicks usually surface on the email side.

SMS for Auto Shops: The Complete Guide to Texting Customers Without Getting Blocked

Why SMS reaches customers when other channels don't

Email gets opened maybe 20% of the time. Voicemail, maybe 30%. A text gets a 95% open rate and a reply inside 90 seconds. In an industry where the customer is almost always driving, waiting, or between tasks, text is the channel that actually reaches them.

Used well, SMS can replace most of what a shop historically did on the phone: appointment confirmations, estimate approvals, "your car is ready" messages, review requests, service reminders, and the occasional "you're overdue" nudge.

Used badly, it becomes spam, gets flagged by carriers, and actually damages your deliverability on every future message.

This guide is how to do it well.

The 5 messages every shop should be sending

Appointment confirmation and reminder. Sent when booked, again 24 hours before, again the morning of. Three touches, each one short.
A "we're working on your car" update when the tech starts. Not required, but customers love it. It's the difference between "I don't know what's happening" and "I'm being kept in the loop."
Estimate approval. A link to a mobile-friendly estimate they can approve or decline from their phone. This one message type eliminates most phone tag.
"Your car is ready," with a pickup window.
Review request, two hours after pickup. One sentence, one link.

That's the entire core SMS stack. Every other text is a nice-to-have.

What NOT to send

Mass promotional blasts to your whole list. Carriers will flag your number within 48 hours and deliverability tanks.
Messages longer than 160 characters unless you truly need them. Longer texts get segmented into multi-part SMS, costs go up, and read rates go down.
Anything that looks like a chain letter or sweepstakes. Carriers have filters tuned for exactly that, and you'll get blocked.
Links that don't match your domain. Bitly, tinyurl, and other shortened links trip filters. Use your shop's domain or a trusted platform's.

TCPA in one paragraph

Under the Telephone Consumer Protection Act, you need prior express consent to send any promotional SMS. Transactional messages like appointment reminders, "your car is ready," and estimate links are generally fine, because they relate to a service the customer already engaged you for. Promotional blasts like "20% off oil changes this weekend!" are a different category and require explicit opt-in. When in doubt, get written consent at the counter or in the booking form.

Full compliance post: SMS compliance for auto shops

A2P 10DLC. The technical gate

If you're texting from a 10-digit local number, US carriers require you to register that number under the A2P 10DLC (application-to-person, 10-digit long code) framework. Unregistered traffic either gets filtered or gets hit with per-message surcharges.

This is a one-time setup. Your SMS platform handles it. But don't skip it. An unregistered number will deliver at 60–70% the rate of a registered one. That's 30% of your messages quietly failing.

How to write a text a customer will actually read

Three rules:

Open with the shop name. Customers don't save your number. If the message starts "Smith's Auto Repair:", they know who it's from in half a second.
Get to the action in one line. "Your estimate is ready: [link]" beats any cleverness.
Always include an opt-out on promotional messages. "Reply STOP to opt out." That's the TCPA requirement and the courteous thing to do.

Example. Appointment reminder:

Smith's Auto: Reminder you're booked tomorrow at 9am for the oil change on the Civic. Reply C to confirm or R to reschedule. Kim

Example. Review request:

Smith's Auto: Thanks for coming in today, Maria! If everything felt right, a quick Google review would mean a lot: [link]

The numbers you should watch

Delivery rate should be 98%+. If it's lower, your number may be filtered.
Response rate on confirmations should run 50–70%.
Click rate on estimate and review links: 20–40% is healthy.
Opt-out rate on promotional messages should stay under 2%. Higher than that and you're over-messaging.

Stop using the shop cell phone

Texting customers from the advisor's personal phone is a disaster waiting to happen. When that advisor leaves, your conversation history leaves with them. You have no audit trail, no compliance controls, and no clean way to hand a customer over to a new person.

Use a real SMS platform that belongs to the shop, not a person.
