NPS-Timed Referral Asks

An NPS-timed referral ask shows a referral offer right after a customer gives a score of 9 or 10. The customer has just said they would recommend you, so this is the easiest moment to ask them to do it.

How it works

Many satisfied customers say they would refer a friend, but far fewer actually do. The gap is often timing. A referral email sent days later arrives after the good feeling has faded. Asking at the moment of the high score turns stated intent into action.

How to do it

  1. Send an NPS survey at a meaningful moment, such as after onboarding, after a repeat purchase, or at a fixed tenure. Use in-app, email, or SMS.
  2. Branch on the score. 9 to 10 (Promoters) get the referral ask. 7 to 8 (Passives) get “What would make us a 10?” 0 to 6 (Detractors) get support outreach.
  3. Show the referral ask immediately after a Promoter submits, on the thank-you screen or in a follow-up sent within minutes.
  4. Include a unique referral link, a pre-written message they can edit, and one-tap sharing by email, text, social, or copy link.
  5. Offer a reward to both sides, for example a free month for the referrer and a free first month for the friend.
  6. If a Promoter has not shared after about a week, send one reminder with a different sharing option.

What to measure

  • Promoter-to-referrer rate: Promoters who share a referral link, divided by all Promoters who saw the ask.
  • Referral completion rate: shared links that lead to a signup or purchase, divided by links shared.
  • Referred customer value: revenue from referred customers compared with customers from other channels over the same period.

Best practices

  • Remove every step you can: pre-fill the message, generate the link automatically, and offer several share options.
  • Show Promoters their impact, for example “Three friends you referred are still customers.”
  • Tailor the suggested message to the feature or product the customer uses most.
  • For email surveys, send the ask in the same thread so it reads as a natural follow-up.

Common pitfalls

  • Asking Passives or Detractors for referrals. They just told you they are not fully satisfied.
  • Waiting more than a day to ask. The moment passes quickly.
  • Offering a reward too small to justify the social effort of recommending you.
