Boost loyalty and repeat purchases with five automated email flows powered by REVIEWS.io, Influence, and Klaviyo.

Reward Strategy

Keeping customers engaged in eCommerce can feel like an uphill battle, especially when competition is fierce. Many shoppers buy once and never return. But with the right strategies, you can build lasting relationships that drive repeat business.

The key to boosting loyalty, increasing CLTV (Customer Lifetime Value), and ensuring consistent repeat purchases lies in creating an automated Customer Engagement Loop. This loop guides shoppers from their first purchase to their next, keeping them continuously involved with your brand.

The best part? You can power this engagement loop on autopilot using the right tools. With Influence, REVIEWS.io, and Klaviyo, you can automate everything from collecting reviews to rewarding loyalty, ensuring your customers stay engaged and your revenue grows without manual effort. Higher average order values, stronger conversion rates, and reduced churn are all possible when the right strategies and tools are in place.

In this article, we explore 5 essential email flows that supercharge the engagement loop, keeping your customers coming back for more.

But first, let’s take a closer look at the customer engagement loop itself and how it connects shoppers to your store and drives sustainable growth.

The Tech Stack Behind the Engagement Loop

To power the Customer Engagement Loop on autopilot, you need the right tools working together.

Influence, REVIEWS.io (both part of the clearer.io suite), and Klaviyo form a connected stack that blends loyalty, reviews, and email automation - delivering timely, personalized experiences that keep customers engaged.

  • Influence fuels loyalty with points, referrals, and tier-based rewards.
  • REVIEWS.io captures authentic social proof that builds trust and credibility.
  • Klaviyo delivers data-driven, segmented emails that reach the right person at the right time.

When loyalty data, powerful automations, and trust-building content come together, you’re not just sending emails, you’re creating high-converting customer journeys. This stack enables you to automate with intent, turning one-time buyers into repeat customers and loyal advocates.

What is the Customer Engagement Loop?

The customer engagement loop is a cycle that connects every customer action to the next, ensuring they stay actively involved with your brand.

It’s a simple yet effective way to turn one-time buyers into loyal fans. 

By connecting key touchpoints in the customer journey, you create an ongoing cycle that drives repeat sales and lasting relationships.

There’s no one blueprint for a customer engagement loop.They can take different shapes depending on your goals and audience. But for eCommerce sales, there’s a simple formula: Purchase, Review, Reward, Repeat. 

  1. Purchase: A customer buys from your store, starting their journey with you.

  2. Review: After the sale, you ask for a review. This builds trust and improves visibility, helping you attract more buyers.

  3. Reward: You thank the customer for their feedback with a reward, like loyalty points or exclusive perks. This keeps them engaged.

  4. Repeat: With their reward in hand, the customer has a reason to shop again, restarting the loop.

This loop doesn’t just drive engagement. It creates a flywheel effect that increases customer lifetime value.

What makes the engagement loop especially valuable is how little manual effort it takes once your flows are set up. 

Using tools like Influence, REVIEWS.io and Klaviyo, you can automate the entire process, leaving you free to focus on scaling your business.

Here’s how it works in practice: 

Customer Purchase: A customer buys a product from your store, triggering a post-purchase email flow through Klaviyo.

Review Request: Klaviyo prompts the customer to leave a review, using REVIEWS.io as the collection platform.

Points for Reviews: Once the review is submitted, Influence automatically rewards the customer with loyalty points.

Points for Reviews: Influence can be configured to reward loyalty points after a customer leaves a review, helping you drive ongoing engagement and repeat purchases.

Follow-Up Emails: Klaviyo, leveraging the review and loyalty data, sends targeted follow-up emails encouraging further engagement, whether it's to redeem points, leave another review, or make a repeat purchase.

Repeat Purchases and Referrals: As the cycle repeats, customers are more likely to buy again, leave more reviews, and refer friends.

Now, let’s dive into the specific flows that bring the engagement loop to life.

5 Customer Engagement Flows to Boost Sales and Retention

1. The ‘Review and Reward’ Flow

The best time to ask for a review is right after a purchase. The customer is still thinking about their experience, so they’re more likely to share their thoughts. 

Adding a reward, like loyalty points, makes it even easier for them to say yes. It’s a simple way to show appreciation while encouraging them to come back.

This flow tackles two challenges at once: increasing reviews and driving repeat purchases. 

Reviews build trust with new customers, while rewards strengthen your relationship with existing ones, creating a strong cycle of engagement.

How the Flow Works

  • Step 1: Customer completes a purchase → Triggers Klaviyo post-purchase email.
  • Step 2: Klaviyo sends a review request email through REVIEWS.io.
  • Step 3: After the review is submitted, Influence rewards the customer with points.
  • Step 4: Klaviyo sends a follow-up email about the customer’s review and points balance.

Benefits:

  • Builds trust with authentic reviews.
  • Encourages repeat purchases.
  • Strengthens relationships by showing customers they’re valued.

2. The 'Points Progress' Flow

A major reason loyalty programs fail is that customers forget about them. This flow ensures that doesn’t happen by making the rewards tangible.

Regular points updates keep the program fresh in their minds. An email showing their current balance, recent activity, and available rewards is a gentle nudge to take action. Highlight perks they can claim now to create urgency.

It’s a small yet powerful way to keep them invested in your program.

How the Flow Works

  • Step 1: Customer earns loyalty points via Influence (via reviews, purchases, etc.).
  • Step 2: Klaviyo triggers a personalized email to show the customer their points balance.
  • Step 3: The email suggests further actions (reviews, purchases) to increase points.
  • Step 4: The customer continues to engage with the brand, boosting retention.

Benefits:

  • Keeps customers engaged in your loyalty program.
  • Encourages faster redemptions and repeat purchases.
  • Makes rewards feel tangible and valuable.

3. The 'VIP Status' Flow

Who doesn’t love being treated like a VIP? When customers reach a new tier in your loyalty program, let them know immediately. 

Celebrate the milestone with a personalized email that highlights their achievements and the perks they’ve unlocked, like exclusive discounts or early access to sales.

By turning milestones into a celebration, this flow rewards customers and adds an emotional element to your program. It motivates others to aim for VIP status while keeping your top customers engaged.

How the Flow Works

  • Step 1: Customer reaches a milestone (e.g., certain number of points) → Influence.io triggers a tier change.
  • Step 2: Klaviyo sends a congratulatory email and updates the customer’s new VIP status.
  • Step 3: Exclusive perks or rewards for the new tier are highlighted.
  • Step 4: The customer is encouraged to make repeat purchases to maintain VIP status.

Benefits:

  • Makes customers feel valued and special.
  • Encourages ongoing participation in your loyalty program.
  • Creates excitement around achieving milestones.

4. The 'Smart Suggestions' Flow

People love personalized suggestions. Use the reviews your customers leave to understand their preferences and recommend products they’ll love. 

For example, if someone praises your skincare range, show them your latest face mask or serum. These tailored recommendations feel more relevant and help build trust in your brand.

Irrelevant recommendations can frustrate customers, but this flow makes your suggestions feel thoughtful and useful. By showing that you understand their needs, you increase the likelihood of repeat purchases and deeper customer loyalty.

How the Flow Works

  • Step 1: Customer leaves a review via REVIEWS.io.
  • Step 2: Klaviyo uses review data and/or survey insights to send personalized product recommendations.
  • Step 3: Influence tracks engagement and rewards for additional purchases or reviews.

Pro Tip: Enhance this flow by collecting zero-party data through REVIEWS.io surveys to better understand customer preferences. Then, boost trust by embedding targeted UGC galleries from REVIEWS.io - showing real customer photos tied to the products you're recommending.

Benefits:

  • Increases sales with relevant suggestions.
  • Shows customers you understand their needs.
  • Builds trust and strengthens relationships.

5. The 'Winback with Rewards' Flow

Customers go inactive for all kinds of reasons, but that doesn’t mean they’re gone for good. A winback campaign reminding them of their unused loyalty points can bring them back. 

Adding a limited-time offer makes it even more effective.

This flow works because it combines two powerful motivators: value and urgency. By reminding customers of unused points and giving them a reason to act quickly, you reignite their interest and encourage them to re-engage with your store.

How the Flow Works

  • Step 1: Customer becomes inactive.
  • Step 2: Klaviyo triggers a winback email highlighting unused points or upcoming rewards.
  • Step 3: Customer is offered a special incentive (e.g., extra points for making a review or a purchase).
  • Step 4: Customer returns to make a purchase or engage with the brand.

Benefits:

  • Revives inactive customers.
  • Increases sales with a sense of urgency.
  • Reinforces loyalty and strengthens customer relationships.
