Email vs SMS for Customer Updates: What Actually Gets Read?
You just finished a repair and the customer needs to pick it up. Do you email them or text them? The answer seems obvious — but a lot of shops still default to email for everything and wonder why customers don't respond.
Let's look at the data, then the practical reality.
SMS vs email open rates: the numbers don't lie
The gap is staggering:
- SMS open rate: 98% — almost every text gets read
- Email open rate: 20% — 4 out of 5 emails are ignored
- SMS average response time: 90 seconds
- Email average response time: 90 minutes (and that's optimistic — many take hours or days)
For a repair shop, this means: if you email “your device is ready for pickup,” there's an 80% chance the customer doesn't see it until tonight — or tomorrow — or never. If you text it, they read it within 3 minutes.
That's the difference between a same-day pickup and a device sitting on your shelf for a week.
Where SMS wins: time-sensitive updates
Text messages are unbeatable for anything urgent or time-sensitive:
- Status changes — “Your repair is in progress” → text
- Ready for pickup — text, always. This is the most important notification you send.
- Approval requests — “Found the issue. $120 to fix. Reply YES to approve” → text
- Appointment reminders — “Your drop-off is tomorrow at 2pm” → text
- Review requests — a text with a one-tap Google review link gets 5–10x more reviews than an email request
These messages need to be seen now, not when the customer checks their inbox tonight. For more on how automatic SMS updates eliminate status calls, see our full breakdown.
Where email still wins: detailed communication
Email isn't dead. It's just not the right tool for quick updates. Email works better for:
- Detailed estimates — a multi-line breakdown of parts, labor, and options is easier to read in email format
- Invoices and receipts — customers expect these in their inbox for record-keeping
- Warranty information — documents the customer might need months from now
- Marketing and promotions — seasonal deals, new services, newsletters
- Terms and conditions — anything legal or detailed
The key difference: email is for “reference later” content. SMS is for “act now” content.
The “both” approach: use each channel for what it does best
Smart shops don't choose one or the other. They use both, strategically:
- Job received confirmation → SMS + tracking link
- Diagnosis / estimate → SMS for alert, email for detail
- Approval request → SMS
- Status update (in progress) → SMS
- Ready for pickup → SMS
- Invoice / receipt → Email
- Review request → SMS
- Follow-up / warranty info → Email
The rule of thumb: if you need a response today, text. If it's for their records, email.
SMS compliance: what you need to know
You can't just start texting customers from your personal phone without consideration. There are rules:
- Consent — you need the customer's permission to text them. An intake form checkbox (“I agree to receive text updates about my repair”) covers this.
- 10DLC registration — carriers now require businesses to register before sending commercial texts. Unregistered messages get filtered or blocked. If you're curious about what this means, check out our 10DLC guide.
- Opt-out — every text should include a way to stop messages (“Reply STOP to opt out”).
- Business hours — don't text at 6am or 11pm. Keep it to business hours.
Using a proper business texting tool handles most of this for you. Texting from your personal number does not.
