Black Friday Cyber Monday (BFCM) is a season of intense competition where every inbox is a battleground. Generic, one-size-fits-all email blasts are now just noise.

So, how do you cut through the clutter and turn your email list into your most powerful sales channel?

The answer lies in moving beyond simple campaigns and embracing intelligent automation. By combining the deep, real-time customer behavior insights from Boost Commerce with the powerful marketing automation of Klaviyo, Boost x Klaviyo delivers automated flows tailored to your most valuable shoppers.

This integration enables you to sync Boost’s rich data, from the first click to final checkout, including every search query, filter applied, and product clicked, directly to Klaviyo profiles.

Let's dive into five specific, high-impact email flows you can set up right now to maximize your BFCM success.

Summary table: 5 email automation flows for BFCM you can create with Boost and Klaviyo.

Flow Type	Trigger	Goal	Recommended Tactic
Pre-Order	Pre-order purchase via Boost	Capture early sales	Build excitement and upsell
Abandoned Bundle	Cart exits with a bundle	Recover high-AOV carts	Value-focused reminders
Search Follow-Up	Search with no purchase	Re-engage interested shoppers	Show relevant alternatives
Price Drop Alert	The product goes on sale	Convert on price sensitivity	Add scarcity and urgency
Back-in-Stock	Inventory restock	Capture missed conversions	Notify instantly, follow up fast

The Pre-Order 'Beat the Rush' Flow

The chaos of BFCM often leads to stockouts on your most popular items, resulting in lost sales and disappointed customers. The Pre-Order Flow allows you to secure revenue before the frenzy begins, guaranteeing sales and rewarding your most eager customers.

The Strategy: Target early-bird shoppers who want to lock in their purchase without the stress of the BFCM rush. Build anticipation and create a sense of exclusivity.
How It Works:
1. The Trigger: When a customer completes a purchase for an item tagged as a pre-order product in Boost, this action triggers a specific flow in Klaviyo.
2. The Audience: High-intent buyers who are so confident in their choice that they're willing to pay in advance.
The Email Sequence:
1. Instant Confirmation & Gratitude: Immediately after purchase, send an email confirming their pre-order. Reassure them their item is reserved and thank them for being a savvy shopper who beat the rush. Reinforce the value: "Your [Product Name] is secured! While everyone else is fighting the BFCM crowds, yours is already waiting."
2. Anticipation & Education (Mid-Flow): A week or so before BFCM, send a reminder that builds excitement. You can share user-generated content, highlight key product features, or suggest complementary items. This keeps your brand top-of-mind and validates their smart decision.
3. Shipping Notification: As soon as the product ships, trigger the final email in the flow, closing the loop and delivering the payoff they've been waiting for.

With Boost’s easy-to-launch setup and pre-order functionality, you can secure sales before BFCM even starts. Merchants have seen an increase in open rates of up to 30% and an average order value (AOV) of 25% post-implementation, thanks to smarter, more proactive merchandising.

The Abandoned Predictive Bundle Recovery Flow

AOV is a critical metric during BFCM. Boost’s Predictive Bundles feature uses AI to suggest complementary items, but what happens when a shopper adds a high-value bundle to their cart and leaves? This flow is your secret weapon for recovering those high-value carts.

The Strategy: Target shoppers who have demonstrated a clear intent to make a significant purchase. Remind them of the incredible value and convenience of the bundle they created.
How It Works:
1. The Trigger: Boost syncs cart events to Klaviyo. The flow is triggered when a customer adds a predictive bundle to their cart but does not complete the checkout process within a set time (e.g., 1-2 hours).
2. The Audience: Your most valuable potential customers—those who were just one step away from a high-AOV purchase.
The Email Sequence:
1. Gentle Reminder with a Focus on Value: The first email should showcase the exact bundle they abandoned. Use dynamic content to pull in the product images. The messaging should focus on the benefit: "Did you forget something? Your perfect [Product Category] bundle is waiting."
2. Highlight the Savings or Solution: The second email can emphasize the value proposition. If the bundle offers a discount, make that the hero. If it solves a complete problem (e.g., a full skincare routine), frame it that way. "Complete your [Goal] with the bundle you built."
3. Final Offer with Urgency: If they still haven't converted, a final email can introduce a small, time-sensitive incentive like free shipping or a small discount to nudge them over the finish line.

Boost’s predictive bundling gently encourages larger baskets by suggesting relevant product combinations. These bundles not only drive AOV but also feel tailored, not pushy.

The Post-Search Smart Recommendation Flow

Imagine a customer searches your store for "waterproof winter boots," clicks on a few pairs, but doesn't make a purchase. With the Boost x Klaviyo integration, that's not a lost lead; it's a powerful data point. This flow uses that data to send a follow-up email that feels like a personal shopping assistant.

Even when shoppers enter vague or misspelled queries, Boost’s intelligent search corrects and personalizes results in real time, ensuring shoppers always find something relevant.

The Strategy: Re-engage shoppers who have shown specific interest but haven't converted by sending them a curated list of products based on their exact search and browsing behavior.
How It Works:
1. The Trigger: Boost sends search and product view events to Klaviyo. The flow is triggered when a user performs a search and/or views products but doesn't make a purchase.
2. The Audience: Inquisitive shoppers who are in the consideration phase.
The Email Sequence:
1. The Helpful Follow-Up: About 24 hours after their search, send an email with the subject line: "Still looking for the perfect [Search Term]?" The body of the email should utilize a Boost AI Product Recommendation widget to display top-rated or trending products that match the query dynamically.
2. Broaden the Scope (or Offer Alternatives): If they don't engage, the next email can showcase related categories or "Frequently Bought Together" items. They may not have found the perfect boots, but they might be interested in winter socks or jacket care products.

Boost’s automated back-in-stock alerts ensure high-intent shoppers don’t just come back—they convert. It’s a second chance at a guaranteed sale.

H3: How do you show only top-rated, in-stock products in a Klaviyo email?

Add filtering rules to the recommendation block in this flow. For example, set Stock level to at least 5, REVIEWS.io rating to at least 4 and review count to at least 10. Only products that match all three appear. Shoppers coming back to a search they abandoned see products that are available and well reviewed, which matters most in BFCM week, when stock moves fast. Turn on "Display REVIEWS.io product reviews" too, and each tile shows its stars and review count.

The Price Drop & Dynamic Discount Alert Flow

Price is a major driver during BFCM. This flow targets users who have shown interest in specific products and notifies them the moment those items go on sale, creating a powerful sense of urgency and personalization.

The Strategy: Capitalize on price sensitivity by automating alerts for shoppers who have wishlisted, viewed, or abandoned a product that is now part of your BFCM sale.
How It Works:
1. The Trigger: This is an advanced flow that uses dynamic segmentation. You'll create a segment in Klaviyo for users who have viewed a specific product (using data from Boost). The flow is triggered when the price of that product is updated in your catalog.
2. The Audience: Price-conscious shoppers who are on the fence, waiting for the right deal.
The Email Sequence:
1. The Price Drop Alert: The moment the price drops, send an immediate, clear, and concise email: "Good news! An item you viewed is now on sale." Use dynamic blocks to show the product, the old price, and the new BFCM price.
2. Urgency & Scarcity Reminder: As BFCM progresses, send a follow-up to this segment reminding them that sale prices and stock are limited. "Don't miss out! Your deal on [Product Name] ends soon."

Pro tip for BFCM: Add a Trending products block to the follow-up email, with a price rule that caps it at your impulse-buy price point (for example, $50 or under). Add a Stock level rule too, so shoppers who missed the original deal still see in-stock, affordable alternatives that are selling now.

The Back-in-Stock 'Second Chance' Flow

Stockouts are inevitable during BFCM. But a sold-out product doesn't have to be a lost sale. Boost's Back-in-Stock feature allows customers to subscribe to alerts, and this flow ensures you instantly notify them the moment they have a second chance to buy.

The Strategy: Recover guaranteed sales by automating notifications for highly anticipated restocks.
How It Works:
1. The Trigger: A customer subscribes to a restock alert for a sold-out product using the Boost "Notify Me" button on your product page. This action is recorded and triggers the flow in Klaviyo once the inventory is updated.
2. The Audience: Your most patient and loyal customers—those who are willing to wait for your product.
The Email Sequence:
1. Immediate Restock Notification: Send an email as soon as the product is back in stock. The message should be direct and urgent: "It's Back! The [Product Name] you wanted is back in stock." Include a clear, prominent call-to-action button that leads directly to the product page.
2. "Selling Fast" Follow-Up: If they haven't purchased within 12-24 hours, a follow-up email emphasizing scarcity can be highly effective. "Don't miss it again! The [Product Name] is selling fast."
