Black Friday Cyber Monday (BFCM) is one of the biggest retail holidays of the year. Businesses all over the world are racing against the clock to win over customers and boost sales. 

With inboxes and ad feeds overflowing, WhatsApp has emerged as one of the most effective channels to cut through the noise. It offers a direct and real-time way to engage with your target market personally.

Unlike email or social ads, WhatsApp messages have open rates of over 90%. But to truly capitalize on this opportunity, your BFCM bulk WhatsApp campaigns must be strategically designed for relevance, urgency, and conversion.

How can you do this?

Let’s look at some best practices for BFCM bulk WhatsApp campaigns.

Why WhatsApp Bulk Messaging is critical for BFCM marketing

Open rates aren’t the only reason WhatsApp is a popular channel among shoppers. 

A recent Forrester study found that 68% of customers they surveyed preferred to buy from businesses that offer convenient communication options—and for many, that means using messaging.

In fact, 74% of online adults want to be able to communicate with businesses in the same way they communicate with friends and family through messaging. This preference is more pronounced during high-stakes, time-sensitive events like Black Friday Cyber Monday.

E-commerce brands are seeing WhatsApp BFCM campaigns outperform legacy channels because:

  • WhatsApp messages have click-through rates of over 45%, compared to 20–25% for email.
  • Mobile-first engagement means messaging lands in the palm of the consumer up to 30 times per day; no other channel matches that immediate visibility.
  • Features like rich media, quick replies, and automated flows make it easy for shoppers to browse products, get help, and buy in seconds.
  • Cart recovery through WhatsApp automation is up to 60% higher than SMS or push notifications.

That’s why agile, high-conversion brands are making WhatsApp their centerpiece for BFCM engagement.

1. Set Clear Goals 

Define measurable objectives before launching your bulk WhatsApp BFCM campaigns. Whether it’s driving traffic, boosting conversions, or increasing average order value, this clarity will help with creating relevant messages and better tracking.

For example, an e-commerce brand might set these goals:

  • Increase traffic to the Black Friday landing page by 25% during the campaign week
  • Recover 30% of abandoned carts with WhatsApp cart recovery flows
  • Boost average order value (AOV) by 15% using exclusive bundle offers via WhatsApp broadcasts
  • Achieve a campaign ROI of at least 5x by directly attributing WhatsApp conversions.
2. Segment Your Audience for BFCM Success

BFCM shopping behavior is intense, time-sensitive, and often segmented by intent and loyalty. Audience segmentation is the backbone of highly effective WhatsApp BFCM campaigns.

Here are some segments you can focus on and what campaigns you can send them:

Cart Abandoners: Shoppers who added items to their cart but didn’t complete checkout in the days leading up to BFCM.


Timing automated WhatsApp reminders with exclusive last-minute offer codes or limited-time incentives can recover up to 60% of these sales.​

Early Access VIPs: Your best customers and frequent buyers who deserve sneak peeks or early access to BFCM deals.

Delivering exclusive offers via WhatsApp makes them feel valued and encourages early conversions ahead of the crowd.

High Browsing Activity Customers: People who frequently viewed or wished for products during the weeks before BFCM but haven’t purchased yet.

Segmenting this group allows targeted “last chance” or “restock alert” messages that spark urgency.

Price-Sensitive Shoppers: Customers who have historically purchased only during sales or with significant discounts.

Bulk WhatsApp messages offering flash deals or bundled discounts cater directly to their buying behavior.

Geographically Targeted Shoppers: Segment based on location to provide precise shipping cut-off reminders, local flash sales, or region-specific product recommendations.

Lapsed Customers: Shoppers who haven’t engaged with your brand in 3-6 months.

Use WhatsApp during BFCM to rekindle interest with “We Miss You” offers exclusive to messaging subscribers.

3. Personalize Your Bulk WhatsApp BFCM Campaigns

Customers expect conversations, not broadcasts. The more you personalize campaigns to shoppers’ preferences, purchase history, and behavior, the higher your engagement and conversions will be.

For BFCM, personalization can take many impactful forms:

Use the customer’s first name to open messages, which immediately feels more human and relevant.

Customize offers based on past purchases or browsing behavior, e.g., suggesting complementary products or restock alerts for items they viewed.

Leverage dynamic product recommendations within WhatsApp messages based on interests or abandoned carts.

4. Timing your bulk WhatsApp messages strategically during BFCM

Timing is everything when it comes to Bulk WhatsApp BFCM campaigns. A perfectly crafted message sent at the wrong moment risks being ignored, while well-timed communication can turn browsers into buyers instantly. With less than a month to BFCM, here’s what you can do in the next four weeks:

Start Your Countdown Now: Focus on list building, teasing early access, and warming VIP segments with exclusive previews in the first week. Use this time to grow your opt-in audience aggressively via click-to-WhatsApp ads, social media CTAs, and website banners promoting “VIP WhatsApp access.”​

Build Anticipation with Early Sends: Send your first high-impact WhatsApp message by the start of November, targeting VIPs and engaged shoppers with early access invites and sneak peeks. This primes your audience and sets expectations for the intensive selling period.​

Reserve Your Pivotal Campaigns for BFCM Week: Plan 2-3 key WhatsApp broadcasts during the heart of BFCM (mid-late November). The goal here is exclusivity and urgency.
In the morning, you can do VIP launches, midday best-seller reminders, and evening flash sales or countdown alerts.​

Leverage Peak Engagement Windows: Schedule your BFCM Bulk WhatsApp campaigns for local peak hours, typically between 8–11 AM and 5–10 PM. These windows align with when users are most likely to read and interact with messages during the holiday season.​

Avoid Sending Too Many Messages Too Often: Limit messages to 1–2 per day during high-volume sale days to avoid fatigue and unsubscribes. Prioritize quality over quantity by focusing on the highest-impact moments and personalized offers.​

Quick Recap Timing Plan:

  • Oct 27–Nov 7: Build your WhatsApp list, start teasing VIP offers and early access.
  • Nov 8–15: Warm-up campaigns with sneak peeks, quizzes, and segmented flows.
  • Nov 16–27 (BFCM Week): Flash sales, countdowns, cart recovery, personalized reminders.
  • Nov 28–30 (Cyber Weekend): Final “last chance” offers, restock alerts, and assisted support messages.
5. Automating bulk campaigns using WhatsApp tools and APIs

WhatsApp’s Business API and a growing ecosystem of tools enable e-commerce brands to design, schedule, and personalize bulk messaging at scale without manual overhead.

WhatsApp Business API:

To send bulk messages legally and reliably, you must use the official WhatsApp Business API. This platform supports:  

  • Sending templated promotional and transactional messages to millions of opted-in contacts.  
  • Managing message throughput without risking suspension or blocklisting.  
  • Two-way conversations, chatbot integrations, and session messaging within 24 hours of user interaction.  
  • Personalizing messages dynamically with customer-specific data fields (name, order ID, product recommendations).

Campaign Automation Platforms:  
Platforms like ZEPIC are built on top of the WhatsApp API to provide user-friendly dashboards for:  

  • Uploading or syncing large contact lists from CRMs and marketplaces.  
  • Segmenting audiences into finely tuned groups responsive to BFCM phases.  
  • Creating and managing multiple approved message templates with rich media.   
  • Automating multistep flows, cart reminders, order confirmations, upsell offers, and support follow-ups.  
  • Tracking delivery, open, reply, and conversion metrics in real time.
6. Ensuring Compliance with WhatsApp Marketing Policies

Staying compliant with WhatsApp’s strict marketing policies is essential to avoid disruptions during BFCM and to maintain customer trust. WhatsApp Business API requires businesses to:

Obtain explicit opt-in consent before messaging customers, clearly communicating what types of messages (promotions, updates) they will receive.

Use only approved message templates for outbound bulk campaigns, which must be submitted and vetted by WhatsApp in advance.

Limit message frequency to prevent spamming; typically, no more than 1-2 promotional messages per day per user are advised during high-volume periods like BFCM.

Comply with local data privacy and regulatory laws, maintaining transparent privacy policies and secure user data handling.

Monitor message quality and engagement, as WhatsApp enforces messaging limits and can restrict or suspend accounts with poor-quality or spammy messaging.

Meta’s move to a per-message pricing model in 2025 further incentivizes quality over quantity, rewarding brands with high engagement and compliance.

7. Measuring campaign success and iterating for improvement

Track these core metrics:

  • Delivery and open rates: Confirm your messages reach the intended inboxes and are read.
  • Click-through and reply rates: Evaluate how many recipients engage by clicking links or responding to CTAs.
  • Conversion and sales attribution: Tie WhatsApp interactions directly to purchases, cart recoveries, and revenue.
  • Opt-out and complaint rates: Monitor unsubscribe rates and user feedback to avoid spamming and reduce churn.
8. Combining WhatsApp with Email and Instagram for Omnichannel BFCM

Combining Bulk WhatsApp campaigns with email marketing and Instagram engagement helps you create a powerful omnichannel strategy to maximize visibility and conversions during BFCM.

  • Instagram is where your audience discovers you; engage with them through DM and comment automation. Bring them back to WhatsApp
  • WhatsApp delivers real-time, direct-to-customer communication that feels personal and urgent. Use it for cart recovery, flash sale alerts, and instant customer support. 
  • Email marketing is ideal for introducing your full BFCM catalog, sharing guides or gift ideas, and providing comprehensive terms or FAQs.

Desperate times call for desperate Google/Chat GPT searches, right? "Best Shopify apps for sales." "How to increase online sales fast." "AI tools for ecommerce growth."

Been there. Done that. Installed way too many apps.


But here's what nobody tells you while you're doom-scrolling through Shopify app reviews at 2 AM—that magical online sales-boosting app you're searching for? It doesn't exist. Because if it did, Jeff Bezos would've bought (or built!) it yesterday, and we (fellow eCommerce store owners) would all be retired in Bali by now.


Growing a Shopify store and increasing online sales isn’t easy—we get it. While everyone’s out chasing the next “revolutionary” tool/trend (looking at you, DeepSeek), the real revenue drivers are probably hiding in plain sight—right there inside your customer data.
After working with Shopify stores like yours (shoutout to Cybele, who recovered almost 25% of their abandoned carts with WhatsApp automation), we’ve cracked the code on what actually moves the needle.


Ready to stop app-hopping and start actually growing your sales by using what you already have? Here are four fixes that will get you there!

Fix #1: Convert abandoned carts instantly (Like, actually instantly)

The Painful Truth: You're probably losing about 70% of your potential sales to cart abandonment. That's not just a statistic—it's real money walking out of your digital door. And looking for yet another Shopify app for abandoned cart recovery isn't going to fix it if you're not getting the fundamentals right.

The Quick Fix: Everyone knows you need multi-channel recovery that hits the sweet spot between "Hey, did you forget something?" and "PLEASE COME BACK!" But here's the reality—most recovery apps are a one-trick pony. They either do email OR WhatsApp, not both. And don't even get us started on personalizing offers based on cart value—that usually means toggling between three different dashboards while praying your apps talk to each other.

Enter ZEPIC: This is where we come in. With ZEPIC's automated Flows, you can:
Launch WhatsApp recovery messages (with 95% open rates!)
Set up perfectly timed email sequences (or vice versa)
Create personalized recovery offers not just on cart value but based on your customer’s behavior/preferences
Track and optimize everything from one dashboard
