How to Build a High-Performing Rewards Program Email Strategy

A well-designed email program is one of the most powerful tools in your rewards program arsenal, but only if it's built with intention. Here's what separates programs that drive real engagement from ones that generate unsubscribes.

Start With the Non-Negotiables

Before you send a single marketing email, get your transactional infrastructure in place.

At minimum, your program will need:

Welcome email: Confirm the extension install. This is their first impression of the product working.
A purchase/cashback confirmation email: triggered immediately when a qualifying purchase is detected. This sets timeline expectations and reduces support inquiries about missing cashback. The copy matters here, e.g. "Your cashback is on its way" outperforms generic language like "Transaction received."
A monthly earnings summary: should include the monthly subtotal + lifetime total. Feature merchant offers with cashback rates. This is the re-engagement AND buying cycle email in one: it reinforces the program's value and drives repeat purchases.

These emails aren't optional. Without them, the product experience breaks. And notably, Wildfire clients that send pending cashback emails see higher customer satisfaction, increased repeat purchases, and fewer support inquiries about missing cashback.

Nail the Onboarding Window

The first few days after enrollment are your highest-engagement window. A welcome email series should accomplish three things: confirm enrollment, drive the first purchase, and educate users on key features.

A proven structure is as follows:

Day 0 confirmation + first-purchase incentive
Day 1 behavioral branch (did they buy or not?)
Day 4 feature spotlight ( SERP cashback notifications, Couponator)
Day 7 mobile extension nudge.

One rule throughout: keep it to one CTA per email. Don't ask users to do three things at once.

Build a Sustainable Engagement Engine

Once users are onboarded, weekly evergreen offer emails keep the flywheel spinning. The data is clear on what works:

Lead with merchant logos. Users scan visuals before reading text.
Use real expiration dates. Urgency outperforms open-ended offers.
Show the boosted rate prominently — "12% cashback, was 4%" is more compelling than any headline copy you'll write.
Flat rate boosts over multipliers. Messaging is cleaner and budget stays predictable.

Layer In Personalization

Behavioral and transactional data unlocks your most valuable campaigns: re-engaging users who browsed but didn't buy, surfacing similar merchants to past purchasers, or strategically leveraging FOMO campaigns showing customers what they could have earned.

With shopping intent signals, you can launch targeted re-engagement campaigns that showcase the most relevant merchants to the user. This can translate into campaigns such as:

Merchant Re-engagement campaigns (previously shopped)
Similar Merchant campaigns
Incentive Bonus to complete checkout (non-checkout shopping events)

The Execution Fundamentals

A few principles that apply across every email type:

Segment before you send. Sending adoption messaging to already-enrolled users wastes impressions and feels tone-deaf.
Classify emails correctly. Transactional vs. marketing classification determines opt-out requirements and regulatory exposure — get Legal aligned early.
Measure the full funnel. From open to click to install to first purchase. UTM parameters and other relevant means to track email response should be built into your plan from day one.
Keep it short. Less content improves email engagement by roughly 19% on average.

Winning programs send the right email at the right moment. Build the infrastructure first, then scale with insights from your program data.
