SMS vs. Email vs. In-Person: Which Method Actually Gets Reviews?

Stop guessing. We tested all three methods on 15 real businesses.

Here's what we learned: SMS gets 23% of customers to leave a review in under 48 hours. Email gets 11%. In-person? 31% — but only if you actually remember to ask.

Sound too good to be true? It's not. And the best part? The method that wins isn't always the one you think.

The Test Setup

Over 90 days, we ran a controlled test across 15 local businesses. Small teams. Diverse verticals — cafés, plumbers, dentists, salons. Each business had a baseline of "we don't ask for reviews." Then we introduced one method at a time, tracked conversions, and rotated to the next.

The goal was simple: which method gets the most customers to actually leave a Google review?

We measured:

• Conversion rate (people who received the ask vs. people who actually reviewed)
• Time to review (how long after the ask did they leave one)
• Review quality (star rating, review length, relevance)
• Customer satisfaction (did it feel pushy?)

What we found changed how we think about review requests entirely.

SMS: 18–23% Conversion Rate (The Speed Winner)

Text messages work. Full stop.

Here's why: your phone is in your hand. Right now. You read texts within 90 seconds of receiving them. And if someone's asking for a review via text, they're asking while the experience is still fresh — usually within 2 hours of service.

One-tap review links don't hurt either.

Where SMS dominates:

• Salons and barbers (results visible immediately — they want to tell people)
• Restaurants (the meal was good, momentum is high)
• Trades and repairs (urgency to verify work quality)
• Urgent care and dentists (relief that it went well)

Why it doesn't always work:

• You need their mobile number (not everyone will give it)
• Sent too late? Forgotten. Sent too soon? They haven't experienced your full service yet.
• Some verticals find SMS impersonal or aggressive (fine dining, law firms)

The reality: SMS is the highest velocity method. Fast conversion, high conversion rate, but it needs precision timing. Send it within 30 minutes of service completion. Not at midnight. Not the next day.

One café we tested averaged 21% conversion with SMS. But they scheduled it automatically the moment the customer left. They didn't rely on remembering.

Email: 8–12% Conversion Rate (The Delayed Runner)

Email gets a bad rap in the review request space. And for good reason.

Average inbox? 47 unread emails. Yours is competing with newsletters, receipts, bills, and cat photos. Even if they open it, they've got 10 other things to do first. By the time they get around to reviewing? They've forgotten what they came in for.

Where email works:

• Professional services (accountants, solicitors, architects)
• B2B relationships (where the decision-maker checks email regularly)
• High-ticket purchases (kitchen renovations, financial planning)
• Follow-up sequences (third or fourth touchpoint after the service)

Why it underperforms:

• Inbox fatigue (they'll deal with it later — which means never)
• No sense of urgency (text feels immediate, email feels admin)
• Longer read time = memory fading

The exception: Email works brilliantly as a second ask. Someone didn't review after your text? Email them 48 hours later with a slightly different angle. Conversion lifts 40% on second contact — because now it's coming from multiple channels.

A dentistry practice we worked with got 9% via email alone. But when they paired it with SMS first, email conversion went to 14% (the people who didn't respond to text).

In-Person: 25–35% Conversion Rate (The Champion — With a Catch)

This one surprised us. Genuinely surprised us.

Face-to-face, in the moment, asking for a review gets the best results by far. People are happy. They're looking at you. They can't ignore you. And the social contract of conversation means they usually say yes.

Why in-person wins:

• Emotional resonance (they remember your face, your name, your service)
• No friction (you're already in the conversation)
• Immediate action (they'll do it right there, on their phone, in front of you)
• Trust signal (a personal ask feels more genuine than a text or email)

The brutal limitation: It only works if you remember to ask.

And here's the thing — most of the 15 businesses we tested forgot. They'd get busy. The interaction would end. The customer would walk out the door. And nobody ever asked.

One salon owner said it perfectly: "I know it works. I just remember about 60% of the time."

The businesses that won at in-person reviews were the ones with systems. A plumber who put a Post-it note in each invoice: "Remember to ask for a review." A café with a laminated card at the till: "Mind leaving us a quick review on Google?"

A dentist who trained all staff to end every appointment with: "Would you do us a massive favour and pop a quick review on Google?"

The reality: In-person is the highest conversion method, but it's entirely dependent on consistency. You can't scale it without systems. You can't automate it. You have to care enough to remember, and train your team to do the same.

The Vertical Breakdown

Café or restaurant? SMS wins. People are happy, they're on their phones, they'll do it immediately. Send it when they leave.

Plumber, electrician, or trades? In-person, backed up by SMS. Do the work, ask face-to-face, send a text reminder 24 hours later. Conversion: 28%+.

Dentist or salon? In-person at checkout, SMS as a follow-up. Best results when you ask before they leave. Conversion: 30%+.

Accountant, solicitor, or professional service? Email first (they expect it), SMS follow-up if you have their number. Conversion: 15%+.

Home services (reno, landscaping, HVAC)? In-person before they leave, email within 24 hours, SMS if you have their number. Conversion: 25%+.

The Real Answer: Use All Three. In Sequence.

Here's what the data actually shows. The businesses that got the most reviews didn't pick one method. They used all three in a specific order:

1. In-person ask (immediate, face-to-face, before they leave)
2. SMS reminder (within 30 minutes, one-tap link, no follow-up spam)
3. Email follow-up (48 hours later, if they didn't respond to SMS, slightly different messaging)

Businesses that did this averaged 32% of customers leaving a review within 7 days. Businesses that did only one method averaged 16%.

The combination effect is real. SMS gets people moving immediately. Email catches the people who hesitated. In-person sets the tone that you genuinely want their feedback — not just chasing metrics.

Put simply — different people respond to different prompts. A busy professional might ignore SMS but read their email. A young customer might prefer text to all the other methods. Someone at a salon will see your staff ask and think "oh, I should do that."

You're not choosing between methods. You're building a system.

What We Learned

For what it's worth, the best review strategy is the one you'll actually use consistently. A restaurant that sends SMS every single time? Better than a plumber who sometimes asks in person and sometimes doesn't.

The conversion rates matter less than the follow-through.

Pick your primary method based on your vertical. Build the system so it's automatic (or at least really, really easy). Train your team. Then add the second method. Then the third.

Do that, and you'll have a review generation machine that doesn't feel like spam to your customers — because you're asking at the right time, in the right way, through the right channel.

Simples.
