Standout Customer Testimonial Email Examples and Subject Lines

According to statistics, 84% of clients trust online reviews and testimonials as much as they would trust personal recommendations of people they know. This is why companies use testimonials to increase their sales and establish a strong online presence.

Testimonial emails contain CTA buttons and information about lucrative deals and generous offers, which makes them so engaging. Read on to find out how to create an effective testimonial email to prompt your potential clients to purchase.

What are testimonial emails?

A testimonial email is a message sent to a long-term client or potential buyer containing testimonials or reviews left by other customers after purchasing products or ordering services. Such short reviews typically contain information about the main advantages of a product and positive impressions about a company.

Testimonials are used when a company needs to:

  • promote new products and services;
  • tell about new offers and deals;
  • drive clients to explore a website and place an order.

Companies use testimonial emails when they want to improve their online presence, build their reputation, and engage potential buyers. By using customer testimonials, a company can demonstrate that it sells high-quality products.

Key advantages of testimonial emails for businesses

If you want to make your marketing efforts more effective, you can’t do without using customer testimonials. They are a must for every professional who wants to set up a successful newsletter.

Customer trust

To establish close relationships with your clients, you need to demonstrate that they can trust your company. Using testimonials left by happy clients, you can show that your products and services help people solve specific problems and have great value for the money.

Tailored messages

Adding testimonials to your emails will make them sound warmer and more welcoming. Moreover, a customer testimonial email containing the reviewer’s personal data and the product your email recipient has recently been browsing on your site will make your message more personalized and relevant to the recipient. It can also help you create a sense of social proof.

High conversions

Make sure to use testimonial emails if you want to increase your conversions. They will provide your customers with relevant information that will drive them to purchase. When writing reviews, customers often mention the key selling points of your products.

How to ask for a testimonial via email

When requesting a testimonial via email, it’s essential to be polite and clear in your communication and provide context for your request. Here are some useful tips to help you write an effective testimonial request email.

  • Personalize your email. Begin your email by addressing recipients by name and using a friendly tone to establish a connection and show that you value their input. This will make them more likely to respond positively to your request.
  • Express appreciation. Show gratitude for the recipient’s past interactions with your product or service. Let them know that you’re thankful for their feedback and that it’s valuable to you.
  • Provide information. Explain more about your testimonial request by elaborating on why you’re asking for feedback and how you will use it. For instance, you can mention that you’re collecting testimonials to feature on your website, social media, or marketing materials. If you already have testimonials online, you can also provide some examples.
  • Follow up. Don’t hesitate to follow up politely if you don’t receive a response after sending your initial request. Sometimes, a gentle reminder can be helpful. However, if a person doesn’t respond to your testimonial request, respect their decision and don’t press further.
  • Send a thank-you message. Once you receive a testimonial, make sure to thank recipients again for their time and effort. Let them know that you appreciate their contribution. You can also reach out further when their testimonial is online.

Finally, writing an effective testimonial request email subject line is crucial to encourage recipients to open your email. Make it clear that you’re asking for a testimonial, and at the same time, keep it short. Here are a few examples of testimonial request email subject lines for your inspiration:

  • Sarah, Share Your Experience with Us!
  • Can We Feature Your Feedback, John?
  • Your Feedback Needed: Help Us Improve!
  • We’d Love to Know More About Your Experience!

Tips for writing testimonial email subject lines

Testimonial email subject lines serve the main purpose of catching the recipient’s attention, compelling them to open the email and consider your offer. You can focus on the specific experiences of your clients while adding testimonials that lend credibility to your claims.

It is crucial to choose an attention-grabbing subject line that instantly engages your customers and encourages them to take action, whether it’s promoting new releases, increasing sales, or improving your online presence.

Some testimonials are accompanied by hashtags that allow people to find more product reviews on social media. Alternatively, you can write a subject line as a question to prompt immediate action. Here are a few examples:

  • Do you want to learn how to use our product to scale up your business?
  • Are you wondering how to make the most out of our product?
  • Do you want to discover how to make your dog happy?

If you want to sound friendly and approachable, keep your testimonial email short and send a friendly reminder saying that your potential clients may want to take a look at the reviews taken by your loyal customers.

Make sure not to overdo it when adding positive reviews, as nobody is interested in false praise. Instead, use reviews from real people who love your products and services.

We love this testimonial email as it is written in a funny and charming way.
