Who doesn’t love something free? Especially from an awesome brand. Programs that reward customers for referring a friend are a win-win for both brands and consumers. Companies bring in new customers and valued shoppers get to give their friends a free gift or get a free gift themselves.

A strong refer-a-friend strategy leads to a higher growth trajectory. Essentially, the more viral, or shareable, your product and brand are the better potential for growth. Seems like a no-brainer, right?

There’s no better way to execute this type of strategy than with a refer-a-friend email campaign. It is, after all, one of the easiest ways to connect with your customers. See below for some great examples, strategic ideas, and considerations for your own campaigns.

Refer-a-Friend Email Examples and Strategy

Before you start worrying about your refer-a-friend email campaign, it’s important to determine what kind of referral program is right for your brand.

Once you’ve got that figured out, proceed to the tips and examples below to create your strategy.

Offer rewards, like discounts or incentives

Rewards and incentives can be a bit risky, as launching a large campaign can have a negative impact on your margins if unsuccessful. Loyal customers plus net-new business have the ability to change your brand and may be the worth risk, just remember to start small! Take a look at this refer-a-friend email example from RocksBox. Adding customers who refer friends to a raffle adds an extra incentive to their program while keeping the financial risk low, as only three people will win the $250 prize money.

Sending your friends a free gift, no strings attached!

This email from Purple Carrot is a great example of a referral program email that counts on the altruism of people. If there’s no incentive to the existing customer, however, there’s likely going to be a lower conversion rate than when there’s something in it for them as well.

Reward social sharing

Okay, so this isn’t purely email but we love what Ipsy is doing nonetheless. An example could be customers sharing your brand on Facebook and Instagram to get 15% off their next purchase or get a subscription box earlier than everyone else. This is a great way to get more reach because you’re utilizing the social element to really expand your voice across customers’ social graph. Keep in mind this technique makes it harder to track success. After all, it’s not the same 1:1 channel as email.

Make it easy

Referral emails can be quick and simple, like this one from Rothy’s. They start the email by explaining what are the benefits of referring (earning $20 credit) and they include a direct referral link. The call-to-action “START SHARING” is available at the bottom, but we like how they included a referral link separately – the sharing process is simplified and customers don’t have to go back to Rothy’s website to start inviting friends.

Include details

Skincare brand Odacité has a 5-step process for referring friends which may seem like a lot. To support the customers through that process they send this email that explains how to refer someone in five short and simple steps. We love how they guide the customers and how Odacité explains what are the benefits of referring.

Capture attention with refer-a-friend subject lines

Clothing subscription company Frank and Oak sends a very simple email with a photo of their products and a single call-to-action. Their strategy is to capture the customer’s attention and increase open rates by providing the details in the email subject line “Share Style Plan and get $15 credit towards your next order 💰”.

Promote your products and services as great gifts for the holidays

Here’s another great example from clothing subscription services. MM.LaFleur relaunched the referral program just in time for Valentine’s day and they sent this email to promote the discount as a great gift for the holiday. The email quickly explains how the referral program works and invites customers to refer friends.

Create a sense of urgency

If you’re running a special promotion or a limited time discount take a look at Blume’s email and see how they created a sense of urgency to encourage the customers to refer their friends as soon as possible. In the subject line, they stated that the offer is ending tomorrow, and in the email, they included an animated timer.

Mention social channels

Rocksbox has an interesting strategy – their referral email is social media-friendly. They ask customers to “screenshot & share” the part of the email that contains the referral code which helps them get more reach. At the bottom, the CTA “Invite Friends” takes customers back to the website from where they can invite others to join.

Send more than one email

Send more than one email to your customers and remind them about the benefits of referring friends. In this example, food subscription service Hello Fresh sends a reminder about the referral program and invites customers to send free meals to their friends.

Ask for geo-specific referrals

Wine subscription company Winc expanded its service and started shipping to a new state. Then, they announced that in an email and asked customers to refer friends that live in that state. This is a great strategy for creating a customer base in the new state and rewarding the existing customers for spreading the good word.

Play to your subscribers' ego

Who wouldn’t want to be the best bestie ever? PrettyLittleThing plays to their subscribers’ ego and offers them a way to be the best best friend they could be: by referring their bestie to the brand. This CTA is more specific than asking subscribers to invite just any friend. It brings their best friend to mind, making the referral request more personal and concrete.

Reward referrers with loyalty points

Subscription box company Birchbox rewards all of its customers with loyalty points whenever they shop with them, so it makes sense for them to also offer loyalty points to shoppers who refer friends to them. We love how clear their email is, with their message in big bold font and money falling from the sky as an animation.

Good to Know

These types of referral programs aren’t for everyone. If you have low margins, it may be harder to deploy this type of strategy (for example, services like Spotify that have high costs). It’s difficult to use this strategy for kids and pet subscriptions too, as the customer isn’t the end-user of the product.

Refer a friend implementation details

You’re probably looking at these examples and thinking, yeah that’s great, but how can I implement a successful referral program myself? Take a look at our five tips below to ensure you’re set up for success.

Start small!

Send the refer-a-friend campaign to a small percentage of your mailing list. Once you’ve got an idea of the conversion rate, determine your budget. You can then put together a larger send based on the conversion rate of the first send (given the audience is comprised of the same filters). You’ll want to keep a close eye on conversion and compare the efforts to your other marketing efforts.

A/B test refer-a-friend email subject lines

When you’re testing your strategy with the initial email campaign, think about A/B testing the subject line. If you haven’t yet, add an emoji or two to one of them. Be careful about your wording though; some subject lines can trigger SPAM filtering including words like FREE, 50% off, Offer, Winner, etc. Use the results of your test to refine your referral process, collect data, and proceed with testing other variables.

Start off targeting your most loyal customers.

They’re likely already your biggest advocates! If you have the data available, target those who’ve made more than one purchase in the past 6 months (for subscription services, at least 2 monthly subscription boxes). Alternatively, if you collect product reviews, you can setup an automated campaign to deploy when a positive review is submitted.

Set up campaign tracking to measure success.

Whether that’s providing a special unique code that the customer forwards to a friend or a url with utm parameters, make sure you’re able to track conversions. Wanna get geeky? Take it a step further by calculating another growth metric, the viral coefficient. Here’s how to calculate yours: the number of people referred * conversion rate = viral coefficient!

Think about the customer experience

It’s critical to make it as easy as possible for customers to share with their friends. If a majority of your customers are opening emails on their phone, think about making your CTA to send a text and create a preformatted text message they can send to their friends in two clicks.

Be careful with your outreach

If you do plan on reaching out to those who were referred instead of them signing up themselves, be careful! You’ll want to ensure that they have context on why you’re emailing them and an opportunity to unsubscribe from further outreach, especially if they’re in the EU (as you’ll need to abide by the GDPR). To put it more bluntly: these referrals aren’t technically part of your main database, so pay particular mind to keep these names cordoned off from your standard marketing—that is until they convert into leads or, better yet, customers!

Use these tips to create your own refer-a-friend email template

An email template makes it easy to build new campaigns and run A/B tests. Use the strategies and tips listed above to create your own refer-a-friend email template or improve the one you already have and start gaining customers.
