So, you’ve been using Klaviyo for a while now. You’ve got your welcome flow dialed in, the occasional promo blast scheduled, and maybe even a cheeky abandoned cart reminder doing its thing.
But let’s be honest: Are you getting the most out of Klaviyo t? Most people aren’t. They treat Klaviyo like any other email tool when, in reality, it’s more like a full-on marketing brain with automations, insights, and features most folks don’t even bother clicking on.
It’s kind of like buying a top-of-the-line espresso machine and only using it to boil water. That’s why we put this guide together – to walk you through underrated Klaviyo benefits and features that can seriously level up your email game.
These tools can quietly double your revenue, reduce unsubscribes, and make your campaigns feel like they were built just for each person on your list. If you’re only using the basics, you’re leaving a lot of performance on the table.
Let’s change that.
10 Klaviyo Benefits To Grow Faster
1. Smart Sending to Reduce Unsubscribes
Ever sent two emails back-to-back and noticed a spike in unsubscribes? It’s not always your content, it could just be email fatigue. Klaviyo’s Smart Sending helps you avoid that by automatically skipping anyone who recently got an email from you.
It’s a quiet little feature, but it packs a punch. Instead of blasting your full list and hoping for the best, Smart Sending respects your subscribers’ inbox space. It helps you stay visible without being annoying, and that’s how you build long-term engagement.
What it is:
A setting that prevents Klaviyo from sending to recipients who’ve received an email from you within a specific time frame.
Why it matters:
Inbox fatigue is real. If your audience feels bombarded, they’re more likely to unsubscribe even if your content is decent. Smart Sending lowers that risk by spacing out your emails automatically.
How to set it:
When creating a campaign or flow email, look for the Smart Sending toggle in the message settings. Once it’s on, Klaviyo will skip anyone who’s received a message from you within your defined window.
Pro tip:
Running frequent promos or daily flows? Customize the Smart Sending window in your account settings. Shorter windows let you stay agile, while longer ones keep you from overwhelming subscribers.
2. Advanced Segmentation for Hyper-Personalized Targeting
Klaviyo’s segmentation isn’t just about splitting your list by geography or age, it’s about getting laser-focused on customer behavior and intent. Think of it as building mini-audiences inside your audience, each one fine-tuned for a specific message.
And the best part? These segments update in real time. You’re reacting based on what your customers are actually doing and not just guessing.
What you can segment by:
- Location
- Purchase frequency or value (CLV)
- On-site activity like product views
- Cart behavior
- Email engagement history
Example segments:
- VIPs who haven’t purchased in 60 days
- Cart abandoners who browsed but didn’t click
- Subscribers who clicked your last promo but didn’t buy
Why it matters:
Mass emails are great if you want average results. Segmentation helps you send the right message to the right person at the right time. More relevancy equals more clicks, more conversions, and fewer unsubscribes. It’s that simple.
4. Send Time Optimization to Boost Open Rates
Ever launched a campaign at 10 a.m. only to get crickets? Timing matters, and not everyone checks their inbox at the same time. With Send Time Optimization, Klaviyo figures out the best time to reach each subscriber based on their past open behavior.
It’s like sending an email with a sixth sense.
What it does:
Analyzes when each person usually opens your emails and schedules delivery at that ideal time.
Why it helps:
Higher open rates, better engagement, and more conversions, all without changing your content. It’s one of those “set it and forget it” tools that just works.
Where to activate it:
When scheduling a campaign, toggle “Send Time Optimization” in the send settings.
Bonus:
It uses machine learning to keep improving over time. So the more you send, the smarter it gets.
5. Back-in-Stock Flows That Rescue Lost Sales
You know what’s worse than losing a sale because something’s out of stock? Not letting the customer know when it’s finally back. That’s where Klaviyo’s back-in-stock flows come in handy as they quietly turn lost sales into found revenue.
When an item is sold out, customers can sign up to be notified once it’s available again. Klaviyo handles the rest, firing off an automatic alert when that product’s back on the shelves.
Why it works:
You already know they wanted it, they signed up for the alert. That’s a warm intent you don’t want to waste.
How to set it up:
Enable back-in-stock notifications for your products via your ecommerce integration (like Shopify). Then, use Klaviyo’s pre-built flow to handle the alerts via email or SMS.
Pro tip:
Add urgency to the alert; something like “Limited quantities available” can nudge people to act fast.
6. SMS and Email Flows Working Together
If you’re still treating email and SMS as two separate channels, you’re missing a trick. Klaviyo lets you blend both into a single flow, so your messages hit harder and follow up smarter.
Let’s say someone doesn’t open your cart reminder email. Klaviyo can send them a quick SMS an hour later to make sure they don’t forget.
Why it matters:
Not everyone checks their inbox, but nearly everyone sees their texts. Pairing SMS with email increases reach and helps you stay top-of-mind.
How to use it:
In Klaviyo’s flow builder, just drag an SMS block into your email flow. You can set it to trigger based on email behavior (e.g., didn’t open within X hours).
Bonus:
You can segment SMS campaigns the same way as email, so no more one-size-fits-all texts.
7. Dynamic Coupon Codes for Real-Time Offers
Generic discount codes are great until they start popping up on coupon sites or getting reused endlessly. Klaviyo’s dynamic coupons solve that by generating a unique, one-time code for each subscriber.
Imagine handing someone a personalized VIP pass—and no one else gets in.
Why it’s better:
You protect your margins, prevent coupon abuse, and create a sense of exclusivity that boosts conversions.
Where to use them:
- Welcome flows
- Birthday or anniversary offers
- Abandoned cart sequences
- Flash sales for loyal customers
Pro tip:
Set an expiry date on your dynamic codes to add urgency. “Expires in 48 hours” gets way more clicks than “Use anytime.”
8. Benchmarks and Performance Comparisons
It’s hard to know if your 23% open rate is killing it or just scraping by unless you’re comparing it to others in your industry. Klaviyo makes that easy with built-in benchmarks right in your campaign reports.
What you can compare:
- Open rate
- Click rate
- Bounce rate
- Unsubscribe rate
Why it helps:
It gives you a clear sense of where you’re winning and where you’re lagging. You’ll know if a campaign underperforms because it was a dud or just because it’s Tuesday and no one’s opening emails.
Where to find it:
Open any campaign report and scroll to the “Benchmarks” tab. You’ll see how you stack up against similar businesses using Klaviyo.
Pro tip:
Use these insights to fine-tune your subject lines, send times, and segmentation strategies.
9. Form A/B Testing Without the Headache
Ever wondered if a different headline or color would boost your signup rate? Stop wondering; test it. Klaviyo makes it dead simple to A/B test your pop-ups and forms so you can make data-backed decisions without needing a data scientist on speed dial.
You can test just about anything: CTA wording, images, layout, background colors, timing, and even which page the form appears on. No complicated setup, no clunky dashboards.
Why it matters:
Even small changes can make a big impact on conversions. A few percentage points can mean hundreds of new subscribers over time.
How to start:
Head into your form builder, click “Create A/B Test,” and choose what you want to experiment with. Klaviyo will automatically split traffic and show you which version wins.
Pro tip:
Let the test run for at least 1 to 2 weeks, depending on traffic. Patience pays off with cleaner results.
10. Integration with Shopify and Beyond
If you’re using Klaviyo and Shopify together, you’re already ahead of the game. But the real power comes when you start leveraging their integration to automate and personalize your entire customer journey.
Klaviyo pulls browsing history, customer tags, fulfillment status, and even custom properties. That means smarter flows, better segmentation, and more meaningful emails. And it’s not just Shopify. Klaviyo integrates seamlessly with WooCommerce, BigCommerce, ReCharge, Facebook Ads, and a stack of other tools.
Why it matters:
More data equals more precision. And when your marketing is based on real behavior, your results speak for themselves.
Pro tip:
Use Shopify data to trigger specific flows like review requests post-delivery, replenishment emails, or first-time buyer follow-ups.
