Referral Program Email

Emails promoting your referral program and encouraging customers to invite others.

Definition

Referral program emails encourage existing customers to refer new users in exchange for rewards. These emails explain the program mechanics, provide easy sharing tools, and remind customers about referral opportunities at strategic moments. Well-designed referral emails turn satisfied customers into a low-cost acquisition channel.

Why It Matters

Referred customers convert at higher rates and retain better than other acquisition channels. Referral CAC is typically a fraction of paid acquisition. Happy customers are often willing to refer but need prompting and easy tools. Email is the primary channel for driving referral program engagement.

How It Works

Announce your referral program to eligible customers. Send reminder emails at strategic moments (milestones, high NPS, after support resolution). Make sharing easy with unique referral links. Track referral conversions and attribute rewards. Notify referrers when their invites convert.

Frequently Asked Questions

The best moments are after positive experiences: milestone achievements, high NPS or CSAT responses, successful support resolution, or usage anniversaries. Ask when customers are feeling good about your product, not randomly.

It depends on your audience. Account credits, extended subscriptions, and premium feature access often work well for SaaS. Cash or gift cards work too but feel more transactional. Two-sided rewards (for both referrer and referee) typically outperform one-sided.

Limit frequency to every few months at most. Only ask happy customers (high NPS, active users). Make unsubscribing from referral emails possible. Frame asks as sharing something valuable, not doing you a favor.
