By the time Cyber Monday arrives, your customers have been bombarded with messages all weekend long. Email inboxes are overflowing, and text message fatigue is real after days of Black Friday promotions.
That’s why your Cyber Monday SMS strategy needs to be different. It’s not about sending more messages at the end of an already intense weekend. It’s about sending smarter ones to the right audience at the right moment. And increasingly, it’s about making sure your text message strategy doesn't operate in isolation.
The brands seeing the strongest results are the ones coordinating text messaging with email and other channels like WhatsApp, creating a consistent experience wherever customers engage.
On its own, text message marketing is undeniably effective: a recent Klaviyo data analysis found that GMV from text messages grew 17.5% YOY in Q1 2026, with repeat buyer growth topping 20%. But brands like Lorna Jane have seen 84x ROI using email and SMS together. And according to research conducted by Klaviyo, brands see an average of 19% growth in gross merchandise value (GMV) in the 12 months after consolidating their email with text messaging in Klaviyo.
That kind of coordinated channel strategy has a compounding effect, and it’s exactly what a smart Cyber Monday SMS approach should be built on.
As client strategy director at ebusiness pros, a Klaviyo Master Silver partner, I’ve been strategizing Black Friday Cyber Monday (BFCM) campaigns across channels for nearly a decade.
Here’s how to make your Cyber Monday SMS campaigns cut through the noise and drive real revenue on the biggest online shopping day of the year.
1. Use RCS to make your Cyber Monday messages shoppable
By Cyber Monday, customers have seen dozens of text messages that all look the same. RCS for Business changes that.
With RCS, you're not limited to a link and a discount code. You can send a rich card with high-quality images, GIFs, and video, plus tappable buttons and swipeable product carousels, so customers can browse and buy without leaving the message thread. And you can do all of this using a verified brand profile complete with your logo, so customers know immediately the message is from you, not a scammer impersonating your brand.
That trust signal matters more on Cyber Monday than at any other time of year, when inboxes and text message threads are at their noisiest.
Where RCS elevates your Cyber Monday text messaging strategy:
- All abandonment flows: Instead of a text-only reminder, send a carousel showing the exact product a customer left behind, with their size, color, and quantity pre-surfaced alongside a one-tap check-out button.
- VIP early access: Reserve a shoppable RCS message for your highest-value segments, featuring reserved inventory with rich product imagery that signals exclusivity without relying solely on a discount.
- Final-hours push: A countdown timer within the message thread adds genuine urgency that plain SMS can't replicate.
One practical note: not every customer's device or carrier supports RCS yet. Klaviyo automatically falls back to SMS or MMS when RCS isn't available, so your message gets delivered regardless. RCS is currently available in the US, the UK, Germany, France, Italy, Spain, Poland, Austria, Sweden, Netherlands, Norway, and Denmark.
2. Reach global customers on Cyber Monday with WhatsApp
Your Cyber Monday SMS strategy might have a gap you haven't noticed: if a meaningful share of your customers are outside North America, you may be sending them the wrong message in a literal sense.
In much of Europe and Latin America, WhatsApp is the channel people actually live on. Countries like Germany, the UK, Spain, and Italy are WhatsApp-native, so sending those customers a text message is a bit like emailing someone who only checks Slack. It'll land somewhere, but that's about it.
The good news is this doesn't mean managing a separate tool or rebuilding your strategy. In Klaviyo, your existing flows, segmentation logic, and customer data also work for WhatsApp. Your abandoned cart timing, your espresso shot segment, your VIP exclusions: all of it applies. The only thing that changes is the delivery channel.
Earplug brand Loop saw 46x ROI in two quarters after consolidating email, SMS, and WhatsApp in Klaviyo, which speaks to what's possible when your marketing channels reinforce each other rather than running in parallel.
A few things to know specifically for Cyber Monday:
- Route customers automatically, from one place. Klaviyo's omnichannel campaign builder lets you design and send a single Cyber Monday campaign across text messaging, WhatsApp, and email, with different message blocks for different audiences, all managed in one place. Layer in AI-powered channel affinity and Klaviyo automatically routes each subscriber to the channel they're most likely to engage with.
- Get rich media without added cost. On SMS, adding images pushes you into MMS, which costs more. On WhatsApp, images, carousels, and CTA buttons are part of the format. There’s no credit penalty. That makes WhatsApp a strong fit for shoppable Cyber Monday messages in markets where it's the dominant channel.
- Two-way conversations feed your data. With Klaviyo, you can automate an instant, on-brand response when a customer in Germany asks, "Do you have this in XL?". That interaction flows back into their Klaviyo profile, sharpening future personalization.

3. Launch a product one month ahead of BFCM to grow your SMS list
If you're looking to grow your SMS list ahead of BFCM, the mechanics matter as much as the incentive.
Klaviyo's Smart Opt-In feature uses your existing customer data to pre-qualify subscribers, so the sign-up experience feels seamless rather than interruptive.
Pair that with AI-powered forms display optimization, which shows people sign-up forms at the time they’re most likely to convert, and you have a list-building engine that’s working before the BFCM rush even begins.
“Growing your SMS list ahead of BFCM gives you a way to see who your true VIPs are,” says Stefan Milicevic, strategy director at London-based Underground Ecom, a Klaviyo Master Elite partner and one of the biggest international partner agencies. “It also helps streamline sending costs.”
As an alternative to Smart Opt-In, tap-to-text is also worth prioritizing specifically for mobile browsers this BFCM. With iOS 26’s inbox filtering changes, Apple automatically classifies subscribers as known senders when they initiate the opt-in conversation themselves.
That means your messages land in the main texting inbox with notifications, not a filtered folder. Klaviyo's tap-to-text forms make this frictionless: a visitor taps a button on your site, their messaging app opens with a pre-populated message, and they send it to subscribe.
4. Focus on your most engaged segments
By Cyber Monday, chances are, your profit margins are tight after days of Black Friday discounting. Every mobile messaging credit you spend needs to work harder.
The economics back this up. Klaviyo’s Q1 2026 data analysis found that new buyer discount rates rose from 9.8% to 10.8%, while repeat buyer discounts actually went down. Brands are spending more to win first-time customers at a moment when margins are already under pressure.
On Cyber Monday, your engaged SMS segment is your most cost-efficient asset.
Start with the espresso shot segment
One of the most effective text message segments for Cyber Monday is what we call the espresso shot segment: people who’ve engaged with your text messages or have been active on site in the last 72 hours, but haven’t bought in that timeframe.
Here’s why this works: customers who engaged recently are demonstrating active interest. They’re opening messages, clicking links, and staying connected to your brand, even during the busiest shopping weekend of the year.
In my experience, this 72-hour engagement window tends to deliver higher average order values compared to broader segments. When you’re conservative with SMS spend on Cyber Monday, this concentrated approach can give you a better bang for your buck.
Exclude recent purchasers
Don’t send Cyber Monday text messages to customers who’ve already purchased during your Black Friday weekend sale. This seems obvious, but it’s easy to overlook when you’re managing multiple campaigns across email and text message marketing.
Set up exclusions for anyone who’s bought since your Black Friday sale started. Focus your texting resources on engaged prospects who haven’t converted yet. These are the people you want your Cyber Monday messaging to reach.
Of course, some marketers see this differently. Maria Trotta, senior SMS digital strategist at Klaviyo, advocates for sending a Cyber Monday text to your entire list, but only if the offer has changed. “Sometimes customers will buy twice within this window if the offer changes are worth it,” she says.
One of Klaviyo's core strengths here is the depth of segmentation available. You're not limited to recency or purchase behavior. You can segment using any piece of data, from any source, across a customer's full lifetime history. That means loyalty tier, product affinity, subscription status, and more can all feed into who gets your Cyber Monday message and what it says.
Send to previous SMS converters
If you have a segment of people who are known to buy from text messages, Cyber Monday is a good time to focus on them. “It’s an extra signal that these people have high intent,” says Jemma Sears, digital marketing manager at Kulani Kinis. “We love to add that layer into our SMS segments.”
5. Create VIP experiences that feel exclusive
Generic discount blasts won’t cut it on Cyber Monday. Your most valuable customers need to feel special, especially when they’re choosing between dozens of competing offers.
On a day when every brand is competing for the same attention, showing up with a message that actually reflects what a customer cares about can be a meaningful conversion advantage.
The good news is that if you're already using Klaviyo, you have the segmentation infrastructure to do this precisely without building anything from scratch. Here are a few ways to do it:
Reserve inventory for VIPs
Consider holding back limited quantities of your bestselling items specifically for VIP customers. Then, use text messaging to offer reserved inventory access on Cyber Monday.
This strategy works because it provides genuine value, not just another discount code. Your message becomes: “We saved this especially for you. Enjoy our sale before it ends.”
Offer mystery benefits
Instead of leading with the same discount everyone else is promoting, try a mystery discount approach for your VIP segment. The curiosity factor can increase engagement rates and make your text messages feel more personal and exclusive.
6. Craft messages that acknowledge the moment
Your Cyber Monday SMS copy should recognize that customers are overwhelmed. Don’t pretend it’s just another day.
Use “Last chance” messaging strategically
If you’re genuinely ending your sale, make that clear. But avoid the trap of constant “Final hours” messaging that customers have learned to ignore.
Instead, focus on scarcity around specific products or inventory levels. “Only 12 left in your size” feels more authentic than “Sale ends at midnight,” especially if customers have seen similar messages all weekend.
“We’ve always been up front about our sales timings, which helps build trust with our customers,” says Sears. “That can give us the leading edge over competitors.”
Address purchase hesitation directly
By Monday, many customers are dealing with decision fatigue. Your text message can help by addressing common concerns:
- “Still deciding? Free returns through January”
- “Questions about sizing? Text back for help”
- “Need it by Christmas? We’ve got you covered”
7. Time your messages strategically
Cyber Monday SMS timing is crucial. You’re competing with every other brand for attention in a crowded mobile landscape.
Avoid the morning rush
Don’t send your primary Cyber Monday message first thing in the morning. Customers wake up to dozens of promotional messages, and yours will get lost in the shuffle.
Instead, consider early afternoon (1–2 p.m.) or later afternoon (5-8 p.m.) when people are more likely to give individual messages attention.
Consider different regions and time zones
“If you’re sending SMS in Europe, you’ll need to take local tempos into account,” Milicevic says. “An Italian customer will be taking their lunch break between noon and 4 p.m., whereas a German person will take theirs around noon. Evenings look different across different regions, too.”
This is also where WhatsApp becomes relevant for your international mobile marketing strategy. In markets where WhatsApp is the dominant messaging channel (much of Europe, Latin America, and beyond), sending a Cyber Monday SMS to a customer who primarily lives on WhatsApp is leaving money on the table.
Personalize timing to the individual
If managing regional timing manually feels like too many variables, Klaviyo’s personalized send time (available if you’re using Marketing Analytics) removes the guesswork entirely. Rather than picking a single send time for your whole list, it uses AI to deliver each message to each recipient at the moment they're individually most likely to engage, based on their own opens, clicks, and purchase history.
For text messaging specifically, personalized send time automatically respects quiet hours, so your Cyber Monday sends stay compliant across time zones without any manual configuration.
Plan for multiple touchpoints
If you’re being conservative with segments, you can afford to send a follow-up text to your most engaged customers.
Plan a strategic sequence:
- Mid-late morning (after quiet hours end): main Cyber Monday offer
- Late afternoon: final-hours reminder (only to those who clicked, but didn’t purchase)
Cyber Monday SMS tip: “Don’t forget to adjust your abandoned cart flows to reflect the sale period, too,” Sears suggests. “We tighten the timing for these messages and adjust the wording to reflect the offer.”
8. Prepare for this year’s unique challenges
This year’s Cyber Monday comes with additional considerations around potential economic uncertainty. Smart brands are building flexibility into their text messaging strategy.
Evaluate every text you send on Cyber Monday through a profit lens. Klaviyo’s Q1 2026 data analysis reflects exactly the kind of consumer behavior you should be planning for: average order value rose just 1.7% in the US, but product prices were up 8.7% and units per transaction were down 6.4%.
Shoppers are spending more but buying less, being more deliberate about every purchase. Your Cyber Monday SMS strategy needs to speak to that intentionality, not just lead with a discount.
Consider text messages that highlight product quality, durability, or long-term value rather than just discounts. This positions your brand well regardless of how economic conditions evolve.
If your margins are already thin from weekend discounting, make sure your Cyber Monday SMS campaigns are genuinely profitable, not just driving vanity metrics.

9. Remember technical considerations
It would be a shame to put all that creative work into your SMS messaging and forget about the nuts and bolts of sending text marketing messages.
Mobile-optimize your messages
Most people will read your Cyber Monday texts while they’re multitasking or shopping with other brands. Here are a few ideas for keeping your texts scannable:
- Lead with the most important information.
- Use clear, actionable CTAs.
- Make the benefit obvious within the first few words.
- Space is your friend. Separate the most important lines with empty space for easy scannability.
Monitor performance in real time
Cyber Monday moves fast. Set up real-time monitoring so you can adjust your strategy if a message isn’t performing as expected. Be ready to send a follow-up with different messaging or to a different segment if the data tells you it’s necessary.
10. Test your way to better Cyber Monday performance
For a high-stakes send like Cyber Monday, even a small lift from testing can mean meaningful revenue at scale. Klaviyo's A/B testing lets you determine the winning SMS campaign version for each subscriber and send it instantly, so you're not guessing which offer, copy, or send time performs best.
You can also use SMS Assistant to create and test on-brand SMS content faster, and Personalized Campaigns AI to automatically optimize which version each subscriber receives based on their individual behavior.
Klaviyo also supports multi-channel A/B testing, so if you’re running coordinated email and text message campaigns, you can test across both channels and find the optimal channel mix for each segment, not just the optimal message.
And if you're running RCS campaigns alongside SMS, Klaviyo's omnichannel A/B testing lets you find the optimal channel mix per segment. This way, you're not guessing whether a shoppable RCS carousel or a punchy SMS drives more conversions for your highest-value customers.
Cyber Monday SMS tip: Do your initial testing in Q3, so your BFCM experiments are grounded in a strong hypothesis. Also! Make sure you budget for the test, as one that goes poorly could be costly.
11. Build trust before customers even click
By Cyber Monday, shoppers are receiving promotional texts from dozens of brands, and many are cautious about clicking links from senders they don't immediately recognize.
If you’re not using RCS, which, remember, sends messages from a verified brand profile, Klaviyo's branded SMS links make your links visibly associated with your brand, growing subscriber trust and boosting engagement before the tap. It's a small detail that matters more during BFCM than at any other time of year, when inboxes and message threads are at their noisiest.
12. Let customers talk back. And use it.
Most brands treat Cyber Monday SMS as a one-way broadcast. That's a missed revenue opportunity. Two-way conversations are one of the most direct ways to personalize customer communications in real time, and feed more data back into every send that follows.
With Klaviyo's automated SMS conversations, you can address FAQs, collect customer preferences, and deliver tailored recommendations, all within the message thread.
K:AI Customer Agent takes this a step further, autonomously resolving support questions, recommending products, and applying promotions mid-conversation, across texting, web chat, email, and WhatsApp, with every interaction feeding back into the customer's Klaviyo profile.
For Cyber Monday specifically, this means a customer who receives an SMS promotion and texts back, “What's your return policy?” or “Do you have this in XL?” gets an instant, on-brand response without your support team lifting a finger. And the data from those conversations feeds back into your Klaviyo profiles, making future personalization sharper.
Combined with cross-channel follow-ups triggered by conversation behavior, this turns a single text message exchange into the start of a longer, more personalized customer relationship.
WhatsApp and RCS take two-way conversations even further for global audiences. With Klaviyo's automated conversations on WhatsApp, customers can browse carousels, tap CTA buttons, and get personalized product recommendations, all without leaving the message thread. The data from those interactions feeds directly back into Klaviyo customer profiles, making your post-BFCM segmentation sharper for every send that follows.
13. Plan beyond Monday
Your Cyber Monday SMS strategy shouldn’t exist in isolation. Think about how it fits into your broader Black Friday weekend sequence and your post-holiday customer journey.
Set up post-purchase follow-ups
Customers who buy on Cyber Monday should receive thoughtful follow-up messages about shipping and delivery. With Klaviyo, transactional texts like order confirmations and shipping updates go out automatically, keeping customers informed without any manual effort from your team. That frees up your Cyber Monday bandwidth for the messages that actually require a human touch.
Capture data for future campaigns
Use Cyber Monday interactions to refine your customer segments for future campaigns.
Who responded to VIP messaging? Which segments converted at higher rates? This data becomes valuable for your next major sale period.
Milicevic suggests implementing an “echoes” strategy with what you learned: “The Cyber Monday offer is ‘repackaged’ into several smaller deals that come out in the following weeks alongside a Christmas sale (or something similar).”
“These typically go to engaged non-purchasers of the BFCM messaging, and they help you either move inventory, capitalize on engagement, or increase your profitability—sometimes all 3,” Milicevic adds.
