A well-written review request email helps you collect authentic, genuine reviews from your customers. And with a good email subject line, you have a higher chance to persuade your customers to open the emails and submit their reviews. According to Marketing Drive, personalized email subject lines increase open rates by 50%. Sounds fascinating enough to put more effort into writing a better email subject? In this article, we’ll show you:

Six tips to write perfect email subjects

1 - Say “thank you” 

Gratitude has great power. If you say “thank you” to your customers, they’ll be more willing to write a review for your product. That’s how the principle of reciprocity works - when the customers receive gratitude, they want to do something in return. For example:

Thank you for your recent purchase at – Review Mi Robot Vacuum Cleaner 

2 - Make your customers feel valued

“In a world where some companies are more concerned with closing a sale than with the happiness of their customers, genuine care is essential. It goes a long way toward establishing the company as a "customer first" entity." (Forbes Coaches Council.)

Everyone has a need for significance - it’s among the six basic human needs introduced by Tony Robbins. So, make your customers feel important by adding to your subject line the phrase “we value your opinion”. This helps you win your customers’ attention and collect a bunch of reviews. 

Here are some great examples from the Judge.me database that you can use:

Review Your KNW Order – Your feedback means the world to us!
✩✩✩✩✩ Your opinion matters to ABB Company!

3 - Keep it relevant 

Your subject line needs to be aligned with the message of your email. In particular, your review request email needs to point out what your customers should do and why. For example:

Review Cherry Lipstick – Help Us Improve our Products & Services

Using this subject line, you answer three questions that your customers have:

  • What should I do? – Review a product.
  • Which product should I review? – Cherry Lipstick.
  • Why should I do it? – To help us improve this product.

4 - Include your customer’s name

As Dale Carnegie’s quote goes, “Names are the sweetest and most important sound in any language.” By including your customer’s name in the subject line, you turn your email into a friendly conversation with your customers, which gives you a higher chance to get reviews. For example:

Hilary, we’d love to hear from you about your recent order with ABB Company!

5 - Be polite and friendly

Your customers are busy, so when they take the time to give you a review, they are doing a big favor for you. Therefore, you should make your email language as polite as possible and avoid being too pushy.

Besides giving a thank-you message, you can also use “please” in the subject line - a simple but powerful word. For instance:

How was your experience with SwissBeauty products? Please give us your feedback

6 - Add emojis

Human process visuals faster than text, so you can add emojis to your subject lines when possible to make your emails more catchy. According to research, brands that use emojis in their email subject lines have a higher open rate of as much as 56% over brands that don’t. In addition, emojis can help you increase the click-through rate.

For example, adding five-star emoji in your subject line makes it clear that this is a review request email. And if your customers are having a good experience with your products, they’ll be happy to click on and give you a review immediately.
