The Power of a Review Request Letter: A Better Way to Get Online Reviews
When it comes to online reviews, most businesses rely on email — but too often, that request gets buried or ignored. If you really want customers to share their experience, a review request letter sent by mail can make all the difference.
Sending the first review request letter shortly after a purchase or service increases the likelihood of a response.
Handwritten cards, postcards, and printed letters are tangible and personalized, helping you stand out and build trust. These formats encourage customers to take action and leave a review, and sending review request letters at the right time helps maximize engagement and collecting valuable feedback that improves your reputation on platforms like Google.
In this guide, you’ll find 25 review request letter templates designed for products and services. Each one is proven to get****positive feedback, and easy to use in your next campaign. Whether you’re asking after a purchase, service, or delivery, these ideas will help you create direct mail that works.
Why a Review Request Letter Outperforms Email for Online Reviews
Most businesses send an email when they want to ask for a review. But with crowded inboxes, it’s easy for your request to be missed. A review request letter stands out to the recipient and is less likely to be ignored compared to email. A review request letter, whether it’s a handwritten card, postcard, or letter in an envelope, makes your ask feel personal and hard to ignore.
Physical mail helps you build stronger connections and encourages customers to leave****online reviews that improve your reputation. When you send a review request letter, it shows you value their feedback enough to invest in a more thoughtful approach — and that makes it more likely you’ll get positive feedback.
A handwritten or well-designed mail piece feels special. It helps customers remember your brand, take action, and share their experience with others.
💡 LettrLabs customers have seen these results firsthand. In this case study, a growing eCommerce brand used handwritten direct mail to successfully boost product reviews and drive more acquisition. Thoughtful, personalized mail made their review requests stand out — and it can do the same for your business.
The Best Mail Formats for a Review Request Letter for Products and Services
Choosing the right mail format for your review request letter can make a huge difference in how many customers respond. Each format has its strengths depending on your products and services, timing, and message.
Including multiple review platform links in your review request letter gives customers more options to leave feedback.
Handwritten Cards
Handwritten cards are perfect for a personalized thank-you paired with a short, friendly review request. They feel authentic and help your business stand out. Great for post-purchase moments or after providing services — especially when you want to ask for positive feedback.
✅ Best for: Heartfelt asks right after a sale or service
✅ Why it works: Builds trust, feels genuine, easy for customers to engage
Postcards
Postcards give your review request high visibility. There’s no envelope — the message is seen right away, which is great for a quick reminder to leave a review. They’re cost-effective and ideal for large-scale campaigns.
✅ Best for: Reminder mailers a few days after delivery or service
✅ Why it works: Immediate impact, simple, budget-friendly
Printed Letters in Handwritten Envelopes
Printed letters (delivered in a handwritten envelope) give you space to tell a story, share your founder’s message, or guide customers through how to leave online reviews. This format works well when your products and services have a backstory or you want to explain the impact of customer feedback.
✅ Best for: Sharing your story, step-by-step review instructions
✅ Why it works: Feels more substantial, great for higher-value products or complex services
Anatomy of a High-Converting Review Request
A strong review request letter is more than just asking for a review — it guides your customer to take action in the easiest, most inviting way possible. Here’s what to include in every mail piece:
GreetingAlways use the customer’s name and reference the customer's specific experience with your products or services. Personalizing the greeting with the customer's details sets the tone and shows you value their feedback.
The AskBe polite and clear about what you’d like. Spell out where and how they can leave a review — whether that’s on Google or another online platform. Example: “Could you take a moment to share your experience at [short link]?”
CTA ToolsMake it easy: include a QR code, short link, or even a reply card. The less effort required, the more likely customers are to respond.
(Optional) IncentiveIf you offer a thank-you gift, ensure it follows review platform guidelines. The goal is to encourage genuine, positive feedback — not force it.
Clean, On-Brand DesignUse clear fonts, plenty of white space, and a real stamp. A well-designed piece reflects your brand and makes a great impression.

Personalization & Automation for Review Request Letters
The key to a successful review request letter is making every customer feel seen and valued. A generic request rarely works — but a personalized touch makes it easy for customers to respond and leave a review.
Handwriting Styles vs. Print
Handwritten cards feel warm and authentic. Choosing a real handwriting style shows you care and helps build trust in your brand. While printed mail can be effective, adding personalized details — like the customer’s name, product, or service — makes your request stand out and increases your chances of getting positive feedback.
Variable Data Printing
Using variable data allows you to customize each piece of mail based on name, products, services, and location. This makes it clear that your business took the time to write just to them — not just anyone. It’s an easy way to create mail that feels personal at scale.
Automation Triggers
You don’t have to manually send every review request. With tools like LettrLabs, you can set up automation to send mail after a purchase, completed service, or loyalty milestone. This ensures your request arrives at the perfect time, improving response rates while saving effort.
Tracking and Optimizing Your Review Request Campaign
To get the best results from your review request letter, you need to track what works and adjust as you go. The good news? Tracking physical mail is easier than ever — and it helps your business continuously improve its reputation.
Measure Engagement
Include QR codes, short links, or reply cards to make it easy for customers to leave a review. With LettrLabs, you can track QR code scans and short link clicks, so you know which requests drive online reviews.
Test Different Formats
Not sure whether a handwritten card, postcard, or printed letter will work best? Run small A/B tests to see which gets more customer feedback. You might find that certain formats work better for specific products and services.
A/B Test Messaging and Design

Common Review Request Letter Mistakes That Hurt Customer Feedback
Even the best-intended review request letter can fall flat if it’s not set up for success. Avoid these common mistakes to ensure your business gets the customer feedback it needs to improve and grow.
No Clear CTA → No Review
If you don’t clearly ask customers where and how to leave their review, they won’t. Every piece should have an obvious, simple request — with a QR code, short link, or reply card.
Too Much Text → Cluttered
A good design keeps things easy to read. Cramming in too much information makes it harder for customers to act. Focus your message and leave plenty of white space.
Generic Copy → Uninspiring
A “one-size-fits-all” request feels cold. Personalized language and references to the specific products and services a customer received will get better feedback.
No Easy Way to Respond
Don’t make people search for how to leave a review. Always include a QR code, short link, or reply card to make responding effortless.
Your Path to More Online Reviews
A well-crafted review request letter does more than just ask for a review — it creates a meaningful, authentic touchpoint that helps your business stand out. Unlike a simple email, physical mail shows you care, encouraging more customers to leave online reviews and share positive feedback about your products and services.
