36 Referral Email Examples To Inspire Your Own

Referral emails are a fixture in any complete referral program. Learn about all the parts that make up a compelling referral email, and take inspiration from the 36 best refer a friend emails being used today.

Updated August 26, 2020




Think of the last email you opened sent by a business – did you make it all the way through before hitting delete? How about a message from a friend? Odds are, you took the time to read it from beginning to end. This is the exact reaction you want when communicating with customers – and you can achieve it with a well-timed referral email.

Rather than coming from a business, a referral email (also called a refer a friend email) is sent from an existing customer to their friend or family member. It’s personal, welcome, and best of all, highly effective in growing your customer base.

Referral emails are a fixture in any complete referral program. Learn about all the parts that make up a compelling referral email – from the referral email subject line to overall design – and see them all in practice in our roundup of the 36 best referral emails being used today.

3 parts of a referral email

Referral emails come with the advantage of having a ready recipient – your existing customer. But, they also pose a few extra challenges.

Unlike most business emails, which are mostly sent to inform, a referral email requires three key steps to work:

  1. A referral email subject line enticing enough for customers to open the email
  2. An incentive or offer too good to pass on
  3. A clear call to action (CTA) that directs them to join the referral program

Do away with one, and your entire referral email may fall short. But cover all three parts, and you have the workings of a great referral marketing program. We offer more details below:

A referral email subject line that gets clicks

When it comes to being clever vs. being clear, the latter is proven to get 541% more clicks. People don’t look at emails to be entertained – they want to know exactly what they’re opening and why they’re opening it.

For example, would you click on an email with the subject “It’s Fri-yay!” or one with “$50 for you, 50% off for your friends”? While there will definitely be a time to show off your humor and wit, referral emails are intended to get customer sign ups – quickly. Do so with a clear call-to-action.

Here are a few more best practices when writing referral email subject lines:

  • Keep it short: Between 6–10 words, or 28–38 characters, to be specific (especially if you’re focusing on a mobile referral program)
  • Personalize it: Adding the recipient’s name into the referral email subject line can increase open rates – even better if it ties into a personal event, like post purchase or after their first year of membership
  • Add a number: Digits get our attention. They help break up text and are easy to take in at a glance
  • Also add an emoji: Emojis can increase email open rates by 29%. They also add personality, save space, and fit well with a lot of modern brand identities. Use wisely.
  • Avoid all caps and excessive punctuation: It looks spammy.

An incentive customers can’t resist

After a strong referral email subject line, it’s best to stick to the point. Include the basics of your referral program – what you’re inviting them to do (refer others), what you’re offering (a strong incentive), and how long the offer stands (one use, one month, ongoing?).

If there are distinct details, list them briefly as well.

  • Are there also rewards for the referred friend? (called a double-sided or two-sided referral incentive)
  • Do the incentives accumulate? (i.e., a customer earns more rewards with each referral)
  • Are there certain conditions needed to receive the reward? (i.e., does the friend need to make a purchase?)

Remember, this is only your introductory email. Start simply. Remove any friction that may cause readers not to refer. You can always create a separate referral program FAQ or landing page to cover all other points.

A clear call to action

Your referral email is read and your customer is interested. Now what? Take them to the next step with a clear call to action (CTA). CTAs are typically a referral link or button leading to more details about the referral program. Or, you can cut straight to the chase and include a referral code for instant sharing.

Robust referral platforms, like Referral Rock or other email marketing tools, can even automate and track all these touchpoints. Seeing the direct results of your referral program – every unique click and code – can help lead to greater sharing success.

No matter which form you choose, a CTA should invite interaction and continue the conversation with your customer. To get readers to click a CTA, apply the following:

  • Smart placement: Place a CTA “above the fold” (the space seen immediately when opening the email) if customers can see what your referral is about. Move the CTA to the end of the email if you need more space to explain your referral details.
  • Visual cues: Draw eyes to your CTA by making the button large and in a contrasting color. Use images that subtly “point” to the CTA (i.e., a person looking in the direction of the button).
  • Strong, actionable text: Rather than the overused “Enter” or “Click here,” use more descriptive verbs, like “Reserve your spot” or “Get my 25% discount.”
  • Create a sense of urgency: Adding a time sensitive phrase, like “before the weekend” or “now” to the end of your CTA will encourage customers to act fast.

The perfect time to send a referral email

When would your customer be the happiest to hear from you? Most probably, right after they’ve made a purchase.

At this point, they’ve already spent some time with your brand and liked it enough to place an order. Engagement is high as their latest purchase – your product – is at the top of their mind.

Make the most of this time by reaching out with a timely refer a friend email, offering even more incentives and value. You could even combine your referral email with an after sales message thanking them for their order or notifying them about a delivery update.

Your customers want to refer you – you just haven’t asked. We automatically ask them at the right time to help word of mouth spread.
