QR code vs text vs email: which review request actually gets answered

Ask ten review software companies which channel works best and you will get ten confident percentages. We went looking for an independent, published study that compares how often customers of home service businesses answer a review request by text, by email or by QR code. We did not find one. The percentages you see in sales decks usually come from the vendor’s own customers, measured the vendor’s way.

So this guide does not invent a winner. It sets out what each channel is good at, what is documented, and a sequence that uses all three where they are strongest.

What we know for sure

Asking works, and customers expect it. In BrightLocal’s 2026 survey of US adults, 78% said a business had asked them for a review in the previous 12 months (BrightLocal). The same survey’s advice to businesses mixes channels: “send timely emails or SMS requests, and include links and QR codes on printed materials.”

Google supports all three. Its help page suggests putting your review link or QR code on receipts, in thank you emails, at the end of a chat and on a printed QR code, and adds that you can send requests “through email, WhatsApp message, or Facebook post” (Google).

Every channel ends at the same door. To post a review, the customer must be signed in to a Google Account. They can create one with an email address that is not Gmail (Google), but that extra step is where many requests die, whichever channel delivered them. A channel that lets the customer act later, on a device where they are already signed in, has an edge.

Text

Why it works for trades. You already have the customer’s cell number, because that is how the job was booked. Nearly everyone can receive a text: 98% of US adults own a cellphone and 91% own a smartphone, according to Pew Research Center (Pew). A text sits in the thread the customer already has with you, so it is easy to find again when they have a quiet minute.

Where it falls short. A text from an unknown number looks like spam. That is the main difference between texting from your own phone and texting through a platform. Platforms send business texts through registered carrier channels; Podium’s pricing page, for example, lists “a base 10DLC fee of $5/month” for US locations (Podium). That registration keeps messages deliverable, but the customer still sees a number they do not recognize unless the platform lets you text from your business line.

Best for: residential service calls, emergency jobs, repeat customers.

QR code

Why it works. It removes typing entirely. If the customer has their phone in hand and you are standing at the door, a scan takes a second. Google generates a review QR code for your profile, though “currently, reviews QR codes can only be generated on a computer browser, not on mobile devices” (Google). Download it once and print it.

Where it falls short. It depends on the moment. A QR code on an invoice gets scanned when the customer opens the invoice, which may be days later. A sticker on your truck gets photographed by nobody. And there is a policy edge: Google now says merchants should not “require or pressure users to leave ratings or write reviews while on the premises” (Google). In a contractor’s world the premises is the customer’s home. Showing a card is fine. Waiting while they type is not.

Best for: a leave behind card on the counter, the bottom of a printed invoice, a showroom or office counter.

Email

Why it works. It suits the jobs that already run on email: estimates, invoices and project updates. It gives room for a proper thank you, and Google itself lists thank you emails as a place for your link.

Where it falls short. It competes with everything else in the inbox, and many homeowners check personal email far less often than texts. For a quick service call, an email can feel formal.

Best for: larger projects such as remodels or roof replacements, property managers and commercial clients.

A sequence that combines them

Two rules hold across the whole sequence. Everyone gets the same request, whatever you think they will write, because Google bans selectively soliciting positive reviews. And nothing is offered in return. Message templates for each step are in how to ask for a Google review by text, and the full list of what is banned is in Google’s rules on asking for reviews.

How to find out what works for you

Since no study can tell you, measure it on your own jobs for a month:

1. Keep a simple list: job, date, channel used, reminder sent or not.
2. Each week, count new reviews on your Google profile and match them to the list.
3. After a month, compare. If texts bring reviews and emails do not, you have your answer for your customers.

Software can do the counting. Automatic tools such as Jobber’s Reviews feature, which sends by email and text with up to two follow ups (Jobber), or NiceJob, which automates text and email requests from $75 a month (NiceJob), report on what they send. Own Your Ratings, made by Pikwize’s publisher, prepares text or email requests that you send from your own phone and shows who opened the link; it has a free plan and a Pro plan at $35 a month (Own Your Ratings). Our comparison of review request tools covers what each costs.

Whichever channel wins in your business, the goal behind it is the same: a steady flow of recent reviews. Why that matters more than the total is explained in how many Google reviews a plumber needs.
