Referral email templates: how to ask customers for referrals (with examples)

Referral email template: what to send, when, and why it works

A referral email template is a ready-to-adapt message that asks a happy customer to recommend you to someone they know, and makes passing on that recommendation easy. The best referral emails are short, arrive right after a good experience, say exactly what the friend and the referrer get, and contain one clear button or link. Below you will find six copy-paste referral email examples, a bank of subject lines, a timing table, incentive options, and a simple way to track every referral with a form.

Key takeaways

• Ask at a high point: right after a positive review, a successful delivery, a renewal, or a solved support ticket.
• Keep the ask to one sentence and one call to action, and pre-write the message the customer will forward.
• Plan at least three emails: the ask, one reminder a few days later, and a reward or thank-you confirmation.
• Track referrals with a form that asks "Who referred you?" or a referral code, then tag those contacts so you can reward the right person.
• Never add a referred friend to your newsletter list unless that friend signs up and consents themselves.

What should a referral email include?

A referral email should include a personal reason for asking, a one-line request, the reward (if there is one), and a single easy way to share. Every element beyond those four makes the email longer without making it more persuasive.

1. Subject line that names the benefit or the person: "Give a friend 15% off" works better than "Our referral program".
2. Personal hook that refers to what just happened: "Thanks for your 5-star review last week."
3. The ask in one sentence: "Know someone who would like this too?"
4. What each person gets, stated plainly with any condition: "They get 15% off their first order; you get a €20 credit once they order."
5. One call to action: a button to a share page or a referral form, or a ready-made message to forward.
6. A low-pressure exit: "No worries if nobody comes to mind" keeps goodwill intact.

The format stays the same whether you sell to consumers or businesses; only the tone and the reward change. Clear, specific subject lines matter here as much as anywhere, and our guide to writing effective email subject lines covers the basics.

When should you ask customers for referrals?

Ask customers for referrals within hours or a few days of a moment when they are clearly satisfied, because goodwill fades quickly. A referral request sent at a random date competes with every other promotion in the inbox; one sent after a good experience reads as a natural next step.

Avoid asking during an open complaint, right after a price increase, or in the same email as an invoice. Those moments make the request feel transactional.

Referral email templates you can copy

Each referral email example below includes a subject line, preview text, and body. Replace the bracketed placeholders, keep the length, and send it from a real person's name where you can. The names, discounts and amounts are examples only.

1. Referral request email template (ask a happy customer)

Subject: Thanks, [First name] — can we ask a small favor?
Preview text: One question, 30 seconds.

Hi [First name],

Thank you for your kind review of [product] last week. It made our day.

Customers like you are how most people find us, so here is a small ask: do you know someone who would enjoy [product] too?

If you share your personal link, your friend gets [15% off their first order], and you get [a €20 credit] once they place it.

[Button: Share my link]

And if nobody comes to mind, no worries at all. Thanks again for being with us.

[Name], [Company]

2. Referral program launch email

Subject: New: give [15% off], get [€20]
Preview text: Our first referral program is live.

Hi [First name],

Many of our customers found us through a friend. Starting today, we want to say thank you for that properly.

Here is how our referral program works:

• Share your personal link or code: [CODE].
• Your friend gets [15% off] their first order.
• You get [a €20 credit] when their order ships. There is no limit on how many friends you can invite.

[Button: Get my referral link]

Full conditions are on our [referral page].

[Name], [Company]

3. Referral reminder email (gentle follow-up)

Subject: Your referral link is still waiting
Preview text: Here it is again, in case it got buried.

Hi [First name],

Just a quick reminder: your personal link is ready whenever you want it. Your friend gets [15% off], you get [€20].

[Button: Share my link]

To make it easy, here is a message you can copy and send:

"I've been using [Company] for [use] and I really like it. Here's [15% off] your first order: [link]"

That is the last we'll mention it. Thank you!

Send one reminder only, and only to people who did not click the first email. A second or third reminder turns a favor into a campaign.

Want to send the reminder only to people who did not click the first ask? Build that group in a few clicks with Mailpro email segmentation.

4. Referral reward confirmation email

Subject: You earned [€20] — thank you, [First name]
Preview text: [Friend's first name] just placed their first order.

Hi [First name],

Good news: [Friend's first name] placed their first order using your link, so your [€20 credit] is now in your account. It is valid until [date] and applies automatically at checkout.

[Button: Use my credit]

Want to invite someone else? Your link stays the same: [link]

Thank you for recommending us.

Send this one as soon as the referral qualifies. A reward that arrives weeks later, or never, is the fastest way to stop people from referring again.

5. Thank-you email to the referrer

Subject: [Friend's first name] joined thanks to you
Preview text: We wanted you to be the first to know.

Hi [First name],

[Friend's first name] signed up today and mentioned your name. Thank you for vouching for us; we know a recommendation is a personal thing.

We'll take good care of them. [If your program has a reward: "Your reward will follow as soon as their first order ships."]

[Name], [Company]

This email works even without a referral program. Service businesses, consultants and local shops often get referrals spontaneously, and a short personal thank-you encourages the next one more than any discount.

6. B2B referral request email template

Subject: Who else should hear about [result]?
Preview text: A quick question after our review.

Hi [First name],

Thanks again for the time at our [quarterly review]. Seeing [specific result, e.g. "invoice processing down from 5 days to 2"] was a great outcome for both teams.

Is there anyone in your network, at another company or in another department, facing a similar challenge? If so, I'd be grateful for an introduction. A two-line email copying us both is perfect, or you can share their details through [this short form] once they've agreed.

As a thank-you, we offer [one month of service free / a donation to a charity of your choice] for any introduction that becomes a client.

Either way, thank you for the trust.

[Name], [Title], [Company]

In B2B, ask for an introduction, not a list of names, and name the result you delivered. A specific outcome tells the client exactly who to think of. Introductions from clients are among the warmest leads you can get; our guide to generating warm leads covers how to nurture them once they arrive.

Referral email subject line examples by type

A good referral email subject line is short, names the benefit or the person, and sounds like it came from a human. These examples are grouped by the job each email has to do.

Avoid "URGENT", all caps, and vague subjects like "Our referral program". Personalization with the first name or the friend's name usually reads as more trustworthy than a discount alone.

Which referral incentives work best?

The best referral incentive is one your customers actually value and that you can afford to give every time; there is no universal winner. Most programs choose between a reward for the referrer, a reward for the friend, or both (a "double-sided" reward). Rewarding both sides makes the friend feel welcomed rather than recruited.

Whatever you choose, write the conditions in one sentence ("when their first order ships", "after their first paid month") and pay the reward on that trigger. In B2B, many employees are not allowed to accept personal gifts, which is why a donation or a service credit for the client company is often the safer offer.

How do you track referrals with a form?

The simplest way to track referrals is a short online form that the referred friend fills in themselves, with a "Who referred you?" field or a referral code field. That one field tells you whom to thank and reward, and it means the friend gives their own details and consent.

1. Create a referral form with the friend's first name, email, a "Who referred you?" or "Referral code" field, and a consent checkbox for marketing emails. You can build one with Mailpro online forms and embed it on a landing page or link to it from your emails.
2. Give each customer something to share: the form link plus their name or personal code, ready to paste into a message.
3. Tag new contacts as referrals so you can count them and treat them differently. Organizing contacts with tags lets you see who came in through referrals and who referred them.
4. Automate the follow-ups: a welcome email to the friend, and a thank-you (template 5) to the referrer. Automated emails send these the moment the form is submitted.
5. Review monthly: export the form responses, count referrals per customer, and send reward confirmations (template 4) for the ones that qualified.

For B2B introductions, a "Recommend a colleague" form filled by the client is fine for passing on contact details, but only after the colleague has agreed to be contacted. Use those details for a personal one-to-one reply, not to add the person to your newsletter list.

Common referral email mistakes to avoid

• Asking too early. A customer who has not received or used the product yet has nothing to recommend.
• Hiding the reward conditions. If the friend must spend a minimum amount, say so in the first email.
• Several calls to action. "Share, follow us, leave a review and refer a friend" gets none of them done.
• Emailing friends who never opted in. Under GDPR and most anti-spam rules, a friend's address given by a customer is not consent to receive your newsletter. Let the friend sign up themselves.
• Sending the same ask to everyone. Customers with an open complaint or a recent refund should not receive it. Exclude them with a segment.
• Forgetting to say thank you. A referral without acknowledgement is usually the last one.

Frequently asked questions about referral emails

How do you ask for a referral in an email?

Thank the customer for something specific, ask in one sentence whether they know someone who would benefit, state what each person gets, and add one button or link. Send it within days of a positive experience and from a real person's name.

What is a good subject line for a referral email?

A good referral email subject line is short and names the benefit or a person, for example "Give 15% off, get €20" or "Know someone who'd like this?". Avoid all caps, urgency words, and generic phrases like "Referral program".

How do you ask for referrals from clients without being pushy?

Ask once at a moment of clear satisfaction, give an easy way out ("no worries if nobody comes to mind"), send at most one reminder, and always thank the client, whether or not they refer anyone.

Can I email the friends my customers refer?

You can send a one-off reply to someone who asked to be contacted, but you should not add them to your marketing list unless they subscribe and consent themselves. The safest setup is a referral form that the friend fills in.

Is a customer referral email the same as a job referral email?

No. A job referral email recommends a candidate to an employer or HR team, while a customer referral email asks clients to recommend your business. The structure is similar, though: a personal hook, a clear request, and one next step.
