About referral emails
Referral emails turn customers into acquisition channels: give-and-get offers, program launches, and reminder sends that put a shareable reward in the subscriber's hands. This hub collects curated referral sends from brands like ResortPass, WeWork and Annmarie Skin Care.
The mechanics that repeat across the grid: a two-sided reward stated as one line ('give $20, get $20'), the sharing action reduced to a tap (a link, a code, a prefilled message), and timing that follows a happy moment, landing after a delivery or a five-star review rather than at random. Design keeps the math unmissable and the friction invisible.
Referral also compounds with the rest of the lifecycle: welcome flows plant the program early, post-purchase sends catch customers at peak enthusiasm, and loyalty programs give the reward somewhere to live. See those neighbors in loyalty emails, post-purchase emails and social proof emails.

Referral email FAQ
What is a referral email?
A send promoting a refer-a-friend program: the offer for both parties, a shareable link or code, and one CTA to send it. It converts existing goodwill into new customers at a fraction of paid acquisition cost.
What referral offer works best?
Two-sided rewards dominate for a reason: the sharer feels generous rather than mercenary because the friend gets something too. Match the reward to purchase frequency, credit for repeat-purchase brands, cash-like rewards for infrequent ones, and keep the math simple enough for a subject line.
When should referral emails be sent?
After delight: post-delivery, post-review, post-milestone. A referral ask that lands while the customer is happiest converts at multiples of a random-calendar blast. Standalone program launches work too, but the triggered sends do the steady work.
Why do referral programs fail in email?
Friction and forgettability: multi-step flows, rewards too small to mention, and one launch email followed by silence. The programs that work keep the ask present at the right moments across the lifecycle without ever being the loudest thing in the inbox.
