A text message gets opened fast, which makes it a tempting channel for referral asks. It’s also the fastest way to irritate a customer who didn’t expect to hear from you. Handled badly, a referral text reads as spam. Handled well, it reads as a timely, useful nudge from a business the customer already likes.
This guide covers the practical side of running a refer-a-friend text campaign: choosing who to ask, timing the message, writing copy people will act on, and staying on the right side of consent and disclosure rules. It’s general information, not legal advice, so run your final setup past a lawyer or your SMS provider’s compliance team.
Quick Answer
Only text customers who have agreed to receive marketing messages from you, send the referral ask right after a good experience, keep it to one short message with a clear reward, and give customers a shareable link or code they send to friends themselves. Make sure any incentive the customer receives is disclosed in the message the friend actually sees, not only on a landing page. Honor “STOP” immediately, and never text a friend’s number that a customer typed into a form unless that friend has consented.
Step 1: Get the consent foundation right
In the US, marketing texts generally require prior express written consent under the TCPA. That means a clear opt-in that tells people they’ll get marketing texts from your business, ideally a checkbox or keyword opt-in that isn’t pre-checked and isn’t a condition of buying. A referral ask is promotional, so it counts as marketing. If a customer only gave you their number for order updates or appointment reminders, don’t use that number for referral asks.
Keep records of when and how each person opted in. If you’re ever challenged, that record is your defense.
Also be aware of the rules on opting out. The FCC’s revocation rules, in effect since April 11, 2025, say customers can revoke consent by any reasonable means, and businesses must honor requests within 10 business days. Words like stop, quit, cancel, unsubscribe, end, and opt out should always be treated as opt-outs. Don’t make people jump through hoops. Just honor it right away. The FCC has delayed a broader “revoke-all” requirement until January 31, 2027, but the simplest policy is to treat any STOP as an opt-out of all your texts.
Step 2: Ask the right customers at the right moment
Annoyance usually comes from bad targeting, not the channel. Send referral asks to people who’ve just had a win: a completed job, a five-star review, a delivered order that arrived on time, or a repeat purchase. Skip anyone with an open complaint, an unresolved support ticket, or a recent refund request.
Timing matters too. Solicitation texts are generally restricted to between 8 a.m. and 9 p.m. in the recipient’s local time, and a few states, including Florida, Oklahoma, and Washington, use tighter evening windows, so check every state you text into. In practice, mid-morning or early evening on a weekday tends to feel less intrusive than a late-night or weekend-morning buzz.
Set a frequency cap. One referral ask per customer every few months is plenty, and don’t send follow-ups to people who didn’t respond. If they wanted to refer someone, they’ll do it or ignore it. A reminder to the same person a day later is where ‘helpful’ becomes ‘pushy’.
Step 3: Write a short, honest message
Lead with your business name so people know who’s texting, say what’s in it for both sides, and give one link. For example: “Hi Sam, it’s Alex at Brightside Cleaning. Glad we could help today! If a friend needs a cleaning, share this link and you’ll both get $20 off your next visit: [link]. Reply STOP to opt out.” Adjust the wording and reward to your own offer, and include whatever opt-out and help language your SMS provider or carrier requires.
Keep the reward simple and specific. Vague offers like “get rewards” get ignored. Make sure the full terms (what counts as a successful referral, expiry, limits) are one tap away on a landing page rather than crammed into the text.
Plan for incentive disclosure. The FTC’s Endorsement Guides treat a payment, credit, or discount tied to a recommendation as a material connection that should be clearly and conspicuously disclosed. The FTC’s guidance says the disclosure should be placed with the endorsement message itself, and that disclosures are likely to be missed if they sit on a profile page or anywhere that requires an extra click. So a note that lives only on your landing page isn’t enough. Tell customers to state the reward where the friend will see it, such as “I get a $20 credit if you sign up,” and make that line part of any share text, email, or post that carries the recommendation. The landing page can repeat the disclosure, but it shouldn’t be the only place.
Step 4: Let customers do the sharing, not you
The riskiest design is one where the customer enters a friend’s phone number and your system texts that friend. The friend never consented to hear from you, and courts have shown they may let claims against the business go forward over referral texts it helps generate. In Jensen v. Capital One, decided in February 2025, a federal court in Washington let claims under Washington state law proceed against a company over a referral text that a customer sent using company-prepared content, and it declined to dismiss the case on Section 230 immunity grounds. That was an early-stage ruling, not a final finding of liability, but it’s a good reason to be careful.
A safer pattern is to give the customer a personal referral link or code and let them share it however they like: their own messages, email, or social media. Some businesses also offer a share button that opens the customer’s own messaging app. If you supply pre-written share text, it should include the incentive disclosure described above, and whether pre-filled copy creates legal exposure depends on your state and facts, so get legal advice first. If you do collect friends’ numbers, get the friend’s own opt-in before you send anything marketing-related.
Tips / Common Mistakes
Common mistakes: texting your whole list at once, using a number that was collected for transactional messages only, ignoring replies, and making the opt-out hard to find. Also avoid sending from a random personal number or from a sender that customers don’t recognize. Use a registered business number through a reputable SMS provider so carriers don’t filter your messages as spam.
Read replies. If someone answers with a question, respond like a human, or route it to someone who will. Track results by referral code so you can see which timing, wording, and reward actually work, and pause the campaign if opt-out rates jump. That’s your signal you’re annoying people.
Finally, treat referral texts as one channel among several. Pair them with an email version, an in-person ask, or a link on your receipt, so customers who don’t like texts still have an easy way to recommend you.

Refer a friend text campaign FAQs
Do I need consent to send a refer-a-friend text to my own customers?
Generally yes. A referral ask is promotional, so in the US you typically need prior express written consent to send it. Numbers collected only for order updates or reminders shouldn’t be used for marketing without a proper opt-in. Confirm your setup with a lawyer.
Can customers enter a friend’s phone number so we can text them?
It’s risky. The friend hasn’t opted in, and businesses can face legal claims over referral texts they help create or send. A safer approach is giving customers a link or code to share themselves, or getting the friend’s own consent before any marketing message.
Do I have to disclose the referral reward when customers share my link?
You should. The FTC treats a reward tied to a recommendation as a material connection that should be clearly disclosed, and its guidance says to place the disclosure with the endorsement itself rather than only on a linked page. Build a short line such as “I get a credit if you sign up” into the share message.
How often should I send referral texts?
Sparingly. Once every few months per customer, sent after a positive experience, is a good starting point. Don’t send follow-up nudges to people who didn’t respond, and stop immediately when anyone replies STOP.
What hours can I send marketing texts?
Solicitation texts are generally limited to 8 a.m. to 9 p.m. in the recipient’s local time, and some states such as Florida, Oklahoma, and Washington use tighter windows. Check the rules for every state you text into.
