Did you know that a well-written review request email helps you collect genuine customer reviews? With professional email subject lines, you will have a higher chance of motivating your customers to open their emails and share their thoughts.

But how do you structure your review requests to have the best chance of scoring a great review? Below are some proven and tested tips that savvy marketers have used in their past product review emails (and their review request subject lines).

Tips To Write a Perfect Review Request Email Subject Line

Personalize your review request email subject lines

Emails that have the best open and click-through rates have concise and clear headers. It could be more efficient to attract a reader with a misleading but attention-seeking subject line, which can lead to better open rates but poor conversions.

Remember that a successful subject line truthfully describes what your email is all about. Some of the best marketing emails are personalized with product and customer information. A survey found that personalized subject lines for business emails increase open rates by 50%.

For instance, Amazon uses subject lines that include the product name, with subject headers such as “How many stars would you give (Product Name)”

Other examples of efficient subject lines are:

  • Let others know if (Product Name) has helped you.
  • Would you recommend (Product Name) to other customers?
  • Hi, (Customer Name), how did you like (Product Name)?
  • Help other customers with your review of (Product Name)!

Also, a good touch that boosts conversion is to add a personal message or signature from someone within the company. You don’t need to go mad when branding the email. Often, the message’s sentiment is far more crucial.

Keep it short

It must be as simple as possible to read your email and follow your CTA. Even the most jaw-dropping copy in overabundance will bore your customer. So, try to catch their attention with a concise message.

That doesn’t mean short, robotic, or choppy sentences. Instead, it must be clear and compelling.

Always address your customer warmly by using personal information like their name and the products they’ve received. Like your subject line, personalizing the email’s body boosts conversion rates by as much as 10%.


Say “thank you” in your review request subject line

Thanking your customer is an excellent way of opening an email. It sets the perfect tone and makes them feel appreciated, which is critical if you want them to help you again in the future.

You can make "Thank You" emails way more special for your customer by addressing them sincerely on behalf of the company director or Founder, or by combining them with rewards or gifts.

Make your customers feel valued.

Genuine and authentic care is critical when establishing relationships with your customers. That’s why you should make your customers feel valued by adding to your email subject lines the phrases such as “Your feedback means a lot to us” or “We genuinely value your opinion.”

Doing this will help you win the attention of your valued customers and get their reviews.

Include promotions or incentives in your review request email subject line

Incentivized reviews have two benefits: they help drive customers back to the website once the review has been completed and may also help boost review collection rates.

It’s essential to remember that while offering incentives or promotions has benefits, it can also have drawbacks. If you become known for discounting (think Domino's Pizza), savvy customers will stick it out and wait for your prices to drop, which could put them off shopping with you when products and services are at full price.

Create a sense of urgency

You must let your customers know that your email contains time-sensitive information if you need them to take immediate action. Using a subject line that starts with "Action Required:" can be a great way to boost open rates here, but be warned, if you're caught crying "Wolf!", you'll lose credibility, so make sure you actually have something that needs immediate attention.

Don’t go crazy with hashtags and punctuation in product review email subject lines

Too much punctuation could make your entire subject line look spammy, particularly if you use many special characters such as $ or !!!. On top of that, hashtags (#) can be flagged by spam.

It will help if you stick to normal punctuation, and your email will appeal to your customers and ISPs alike.

Warm up your email campaigns

It's tricky enough to craft the perfect review request subject line, but then you need to make sure it's actually delivered! This is where email warm-up comes in.

Email warm-up is essential for new and low-activity email accounts. That’s because emails sent from un-warmed inboxes are more likely to land in spam (especially in the case of cold emails). Warmed domains have better distribution capacity and always earn you better results when you're emailing.

Email Subject Line Examples

Email Subject Lines Requesting for Customer Feedback

When you ask for feedback, make it as clear and simple as possible. A subject line with a quick question is the most typical way of doing that. Remember, the goal is to get a click-thru, so being slightly vague can actually help! Here are some examples for you to try:

  • Thoughts about (Product Name?)
  • Hi (Name), mind helping us out?
  • Discount on your next order?
  • How did we do?

Subject Lines for Product Reviews

Many eCommerce stores will get a review when they ask for one; it's almost an expectation nowadays. You'll improve your chances of scoring product reviews by getting the timing - and the personalized message - right. Of course, you need great subject lines for your review request emails, too, or else they won't get opened.

So, what are the best subject lines for product reviews? Consider the following examples:

  • What do you think about (Product Name)?
  • Tell us about (Product/Service) and receive (Incentive)!
  • Thoughts about (Product or Service Name)?
  • Take a minute to tell us how we did!

Offer them rewards

Let’s be honest. Giving special rewards, promotions, and discounts to your customers in return for feedback is a good strategy to get your customers’ attention. The only thing you must do is to ensure your subject line showcases the offer.

Here are some examples for you to try:

  • We are offering (Reward) for telling us what you think of (Product Name)!
  • Get XX% discount for giving us your essential suggestions!
  • Get XX% for your next purchase when you review (Product Name)!
  • Can’t miss the deal! Save XX% on your order today when you tell us your experience with (Product Name)

Subject Lines for Comments and Suggestions

Are you planning to send emails asking for suggestions and comments? You can also take a direct and simple approach. In this case, your subject line should explain that you wish to improve the product or service for our customers, making their comments valuable.

Here are some examples for you to try:

  • How can we make our (Product Name or Service Name) work for you?
  • What (Product or Features) would you like to experience from us next?
  • Is there anything our team can do to improve our (Product or Service Name)?
  • Your honest opinion can help us improve!

Subject Lines for Thank You Emails

If your customers have been generous enough to leave a review or share their feedback, it is only a common courtesy to send them a Thank You email. Some subject lines you can use are:

  • Thank you so much for being honest with us! Here’s a special present for you!
  • So happy to have you as our customer. Thanks a lot for your support!
  • Thanks for your feedback. You make us a lot better.
  • Your feedback is valuable to us. Thanks for your time!
  • Special thanks from our CEO!

Email Subject Lines for Customer Satisfaction Survey

Finally, customer satisfaction surveys differ from performance feedback requests and product reviews. Those surveys are utilized to obtain audience responses based on their satisfaction with the service or product.

The focus is not necessarily on what’s good or bad about the product. Instead, it’s more about how much the customer likes it. Hence, CSAT surveys put your product or service's features into the spotlight, within the context of the customer experience.

Here are some subject line examples you can use:

  • Was (Product) all you hoped for? Let us know!
  • Tell us about your experience with (Product)
  • Help us out with some quick feedback?
  • Did you enjoy your experience with (Brand Name)?
  • What did you think?
  • Quick question about (Product)
