Black Friday and Cyber Monday are peak season for eCommerce, but they’re also peak competition. With so many brands shouting the same messages, shoppers scroll past unless something grabs their attention. 

UGC does exactly that. 

Research on UGC shows that when brands use it in their marketing, 84% of shoppers trust them more, and 77% are more likely to buy.

With the REVIEWS.io + Klaviyo integration, you can drop authentic reviews and UGC straight into your email flows. So instead of relying on urgency alone, you add credibility through genuine customer experience.

From teasers to win-backs, these five UGC-powered flows turn your BFCM emails into campaigns that convert.

5 UGC-Powered Email Flows for BFCM Success

1. BFCM teaser emails: How do I use UGC to build pre-sale momentum?

Shoppers start browsing long before BFCM officially begins. If your teasers only hint at discounts, you risk blending in with every other brand in the inbox. 

UGC makes teaser emails more persuasive by showing that your products are already trusted and loved, building anticipation and credibility before your sale even starts.

The flow

Email 1: ‘coming soon’ with proof 

Share your overall star rating alongside a recent 5-star review to set a foundation of trust. This gives shoppers confidence that what’s coming is worth waiting for.

Email 2: product teaser with reviews 

Spotlight a hero product and add SKU-linked reviews. Show that it’s already a customer favorite to spark early interest.

Email 3: proof in pictures 

Embed a shoppable UGC gallery block with authentic customer photos. Real-life images create excitement and prove that people genuinely enjoy your products

Don’t just tease discounts. Build anticipation with proof that your products are already loved and trusted.

2. BFCM launch emails: How do I use UGC to make my sales campaigns more credible?

When BFCM launches, inboxes overflow with discounts. Shoppers are skeptical, needing proof to distinguish hype from reality. 

Embedding reviews, ratings, and UGC turns your launch campaigns into credible, trustworthy communications that shoppers can believe in.

The flow

Email 1: sale live with reviews 

Announce your discounts and support them with a block of recent product reviews, showing that deals apply to proven winners.

Email 2: personalized recommendations with proof 

Use SKU-specific reviews tied to customer browsing or purchase history. This way, shoppers see evidence directly tied to products they’re interested in.

Email 3: social proof push 

Add a UGC gallery showcasing lifestyle photos or videos of bestsellers. Seeing how others use your products validates your offers and drives urgency to buy.

UGC turns your BFCM launch from just another discount drop into proof shoppers can trust.

3. BFCM abandoned cart emails: How do I use UGC to recover more lost sales?

Cart abandonment is high during BFCM - often because of hesitation, not price. To reduce cart abandonment rate, you need to remove doubt and build confidence. 

With reviews, star ratings, and authentic customer photos, you give hesitant buyers the reassurance they need to complete their checkout.

The flow

Email 1: reminder with review snippets

Display a recent review for the abandoned SKU (e.g., “Fit perfectly, quality is excellent”) to directly counter doubt.

Email 2: aggregate proof 

Highlight the product’s average star rating and total number of reviews. This demonstrates popularity and reinforces credibility.

Email 3: urgency + social proof 

Combine a time-limited sale message with a powerful 5-star review or a lifestyle photo of someone enjoying the same product. This creates both urgency and reassurance.

Skip the extra discounts. Win back carts by showing proof that others bought, love, and recommend the same product.

4. BFCM win-back emails: How do I use UGC to re-engage lapsed customers?

Many BFCM shoppers buy once and never return - unless you re-engage them. 

UGC makes win-back campaigns effective by reminding lapsed buyers of their positive experiences while showing them that other customers are still enjoying your products.

The flow

Email 1: fresh proof 

Resurface reviews for products they previously purchased. Highlighting a 5-star comment acts as both a memory trigger and a trust refresher.

Email 2: social proof update 

Introduce new products with a UGC gallery featuring lifestyle content from other customers. This positions your brand as fresh, relevant, and trusted.

Email 3: incentive + proof: 

Pair a loyalty or referral incentive with authentic UGC. For example, spotlight loyalty rewards alongside photos of products members love.

UGC reminds past buyers what they loved before - and shows them why it’s worth coming back for.

5. BFCM cross-sell emails: How do I use UGC to increase average order value?

BFCM often brings in new buyers who purchase just one product. Cross-sell emails are your chance to grow order value, and UGC makes those recommendations more persuasive. 

Instead of feeling like upsells, they feel like credible suggestions supported by proof.

The flow

Email 1: after purchase with reviews

Recommend related items using SKU-linked reviews, making the upsell feel personal and trustworthy.

Email 2: social proof spotlight 

Share a UGC gallery showing how customers pair products together in real life (e.g., “Customers who bought X also styled it with Y”).

Email 3: gentle upsell with ratings 

Use star ratings and review counts to present add-ons or bundles. By showing popularity and satisfaction, you make the upsell an easy yes.

UGC makes cross-sells feel like customer-backed recommendations, not pushy promotions.
