Klaviyo Email Marketing Campaign: Guide & Benchmarks 2026
TL;DR
A Klaviyo email marketing campaign is a one-time, manually scheduled email sent to a pre-built list or segment inside Klaviyo. Unlike automated flows (which trigger based on customer behavior), campaigns are planned broadcasts you control, perfect for promotions, product launches, and newsletters. In 2026, the average campaign open rate sits around 31% and the average click rate is 1.69%, though segmented campaigns dramatically outperform unsegmented ones. You need both campaigns and flows for a complete email retention strategy.
A Klaviyo email marketing campaign is one of two core ways to send email inside the platform. The other is a flow. Confusing the two is the most common mistake new Klaviyo users make, and understanding the difference changes how you think about your entire email strategy.
This guide defines what a Klaviyo campaign actually is, explains when to use one (and when not to), covers the types worth sending, and gives you 2026 benchmarks so you know what “good” looks like.
If you’re new to the platform, our complete guide to Klaviyo covers the broader ecosystem before you dig into campaigns specifically.
What Is a Klaviyo Email Marketing Campaign?
A Klaviyo email marketing campaign is a one-time email you send to a pre-built audience (either a list or a segment) at a time you choose. You pick the recipients, design the email, set the subject line, and either hit send immediately or schedule it for later.
According to Klaviyo’s official glossary, an email campaign is “a one-time planned email that you send to a pre-built list of recipients to promote a product, service, or event.”
The key word is “planned.” Campaigns don’t fire automatically when someone abandons a cart or makes a purchase. You decide the timing, the audience, and the message. That’s what makes them different from flows.
Klaviyo is used by more than 183,000 brands, the vast majority of them ecommerce stores running on Shopify. Campaigns are the bread and butter of how these brands communicate promotions, share content, and drive time-sensitive revenue.

Campaign vs. Flow: The Distinction That Matters Most
If there’s one thing that trips up Klaviyo users, it’s the campaign vs. flow question. Practitioners on Reddit’s r/Klaviyo community ask about it constantly, and nearly every competitor article addresses it because the confusion is that widespread.
Here’s the simplest way to think about it: campaigns are what you send, flows are what Klaviyo sends for you.
Campaign | Flow | |
|---|---|---|
Trigger | You decide when to send | Triggered by customer behavior (browse, purchase, signup) |
Timing | Manually scheduled or sent immediately | Fires automatically when the trigger occurs |
Audience | Pre-built list or segment | Individual recipients who match trigger criteria |
Use case | Promotions, newsletters, announcements | Welcome series, abandoned carts, post-purchase |
Revenue role | Time-bound spikes (30-40% of email revenue) | Steady compounding (60-70% of email revenue) |
Management effort | Requires regular creation and scheduling | Set up once, optimize periodically |
The revenue split is worth paying attention to. According to practitioner data from ecomflows.io analyzing 2,000+ stores, flows generate 60-70% of total email revenue. Klaviyo’s own data shows flows generated nearly 41% of email revenue from only 5.3% of total sends, with flow click rates averaging 5.58% versus 1.69% for campaigns.
But campaigns still matter, a lot. One well-timed Klaviyo email marketing campaign can generate more revenue in a single day than a flow generates in a week. Campaigns are how you capitalize on moments: a flash sale, a product drop, a holiday weekend.
You need both. For a deeper look at the flow side of this equation, see our breakdown of the 17 best Klaviyo flows.
Types of Klaviyo Email Marketing Campaigns
Not every campaign is a discount code blast. The best ecommerce brands use a variety of campaign types to keep their audience engaged without training subscribers to wait for the next sale.
Sales and Promotion Campaigns
The most common type. Black Friday, flash sales, end-of-season clearance, sitewide discounts. These drive the biggest single-day revenue numbers. Timing and segmentation make or break them.
New Product Launches and Restocks
When you drop a new product or restock a bestseller, a campaign is the right tool. These work especially well when sent to segments of customers who previously browsed or purchased similar items.
Newsletters and Editorial Content
Brand stories, educational content, curated product picks, founder letters. Newsletters build long-term brand affinity and keep you in the inbox between promotions. They also give you a reason to email without always discounting.
Seasonal and Holiday Campaigns
Valentine’s Day gift guides, Mother’s Day roundups, back-to-school promotions, summer sale kicks. Seasonal campaigns align your messaging with what customers are already thinking about.
VIP and Segment-Specific Campaigns
Early access for top customers, loyalty rewards, exclusive previews. These campaigns reward your best buyers and make segmentation tangible. Our guide on VIP email marketing strategy covers this in detail.
Win-Back One-Time Sends
A targeted blast to lapsed buyers who haven’t purchased in 90, 120, or 180 days. While win-back flows handle this on autopilot, a one-time campaign with a compelling offer can re-engage a chunk of your list in one shot.
Event-Driven Campaigns
Webinar invitations, live shopping events, store openings, pop-up announcements. Any time there’s a specific date and a specific action you want subscribers to take, a campaign is the right vehicle.

How a Klaviyo Campaign Works (Step by Step)
Creating a Klaviyo email marketing campaign follows a straightforward process. Here’s the summary:
1. Choose Your Audience
Select a list or segment to receive the campaign. This is where segmentation decisions happen. Sending to your full list is almost never the right call (more on that in the mistakes section). Understanding the difference between Klaviyo lists and segments is important here, because the audience you choose directly affects engagement and deliverability.
2. Build the Email
Use Klaviyo’s drag-and-drop editor, start from a template, or import custom HTML. The editor is straightforward, though some Shopify App Store reviewers note that template aesthetics and font options can feel limited. For most brands, the built-in editor handles the job.
3. Write and Test the Subject Line
Your subject line determines whether people open. Klaviyo offers built-in A/B testing: test two or more subject lines on a portion of your audience, and the platform automatically sends the winner to the rest. According to Klaviyo’s product page, this continuous experimentation means each campaign can outperform the last.
Klaviyo’s AI tools can also suggest subject lines and draft email copy if you’re stuck.
4. Schedule or Send
You can send immediately or schedule for a future date and time. For time-sensitive promotions, scheduling during peak engagement windows (typically mid-morning on weekdays for most ecommerce audiences) improves results.
5. Review Post-Send Analytics
After the campaign goes out, monitor open rate, click rate, revenue per recipient (RPR), placed orders, and unsubscribe rate. These numbers tell you what worked and what to adjust next time.
Key Benchmarks for Klaviyo Campaigns in 2026
Knowing what “good” looks like prevents you from celebrating mediocre results or panicking about perfectly normal numbers.
According to Klaviyo’s 2026 benchmark data across 183,000+ customers:
Average campaign open rate: 31%
Average campaign click rate: 1.69%
Top-performing campaign click rate: ~3.38% (top 10% of brands)
Average campaign RPR (revenue per recipient): ~$0.11
Average abandoned cart flow RPR: $3.65 (for comparison)
The revenue gap between campaigns and flows is massive. Flows convert at roughly 25x the rate of campaigns. That doesn’t mean campaigns are weak; it means they serve a different purpose. Campaigns reach broad audiences with a single message. Flows reach the right person at the right moment.
The Apple Mail Privacy Problem
Open rates are unreliable in 2026. Apple’s Mail Privacy Protection (introduced in 2021) pre-loads tracking pixels for Apple Mail users, artificially inflating open rates. The median ecommerce email open rate now sits between 18-25% for campaigns, but some brands see numbers above 35% purely because of this inflation.
The two metrics Apple can’t inflate are click rate and revenue per recipient. Both require a real human to actually click or buy. Use those as your real engagement signals.
For strategies to improve these numbers, see our guide on how to optimize Klaviyo email campaigns.
Best Practices for Klaviyo Email Marketing Campaigns
Segment Before You Send
This is the single highest-impact thing you can do. According to Klaviyo’s segmentation data, segmented emails generate 760% more revenue than non-segmented campaigns. Their benchmark report analyzing 2.5 billion emails found that properly segmented campaigns produce 3x higher earnings per recipient, 1.63x higher open rates, and 2.16x higher click rates.
Practitioners confirm this. One retailer shared that their click-through rate hovered around 1.2% until they split their list into behavioral segments based on product type, price range, and purchase frequency. Within eight weeks, their average CTR jumped to 3.8%.
For a deeper look at how to build these segments, read our email list segmentation strategies guide.
Send 2-3 Campaigns Per Week
Practitioners on ecommerce forums and YouTube walkthroughs consistently land on the same range: 2-3 campaigns per week to engaged segments is the sweet spot for most D2C brands. Klaviyo’s own best practices suggest at least 8 campaigns per month targeted at a variety of different customer segments.
More than 4-5 per week risks list fatigue. Fewer than 2 and you’re leaving revenue on the table.
One contrarian perspective worth considering: a fixed weekly schedule ignores how real people shop. Some practitioners argue you should map your send cadence to actual product repurchase cycles rather than sticking to an arbitrary weekly schedule.
A/B Test Every Campaign
Test subject lines at minimum. Over time, test send times, email length, CTA placement, and design variations. The compounding effect of small improvements across dozens of campaigns is significant.
Suppress Unengaged Subscribers
Remove anyone who hasn’t opened or clicked in 90+ days from your regular campaign sends. This protects your sender reputation and improves deliverability for the people who actually want to hear from you. Klaviyo’s Smart Sending feature also prevents over-sending to individuals who’ve received recent emails.

Common Klaviyo Campaign Mistakes
Sending Every Campaign to the Full List
This is the fastest way to destroy your sender reputation. ISPs like Gmail and Yahoo track engagement rates. When a large percentage of your list ignores your emails, future sends get routed to spam, even for subscribers who want them. Segmentation isn’t optional; it’s a deliverability requirement.
Ignoring the 4,000-Profile Threshold
Practitioner data from ecomflows.io highlights an important economic reality: Klaviyo campaigns don’t make economic sense below roughly 4,000 active profiles. Below that number, the effort of planning, designing, writing, and scheduling campaigns doesn’t generate enough revenue to justify the time. Smaller lists are better served by focusing on growing the list and letting flows do the heavy lifting.
Treating Open Rate as a Reliable Metric
Because of Apple Mail Privacy Protection, open rates are inflated across the board. Brands that optimize for open rate alone end up making decisions based on noisy data. Click rate and revenue per recipient are the metrics that reflect actual human behavior.
Not A/B Testing
Every campaign sent without a subject line test is a missed learning opportunity. Over months, A/B testing compounds into meaningfully better performance.
Running Campaigns Without Supporting Flows
A campaign might drive someone to your site, but if your abandoned cart flow, browse abandonment flow, and post-purchase flow aren’t set up, you’re losing the downstream revenue that campaign generated. Campaigns and flows work together.
Klaviyo Pricing and Campaign Economics
Klaviyo’s free plan covers up to 250 active profiles and includes core email functionality (with Klaviyo branding on emails). Paid plans start around $20/month and scale by profile count. The send limit at each tier is roughly 10x the active profile count, so a 1,000-profile account can send about 10,000 emails per month.
This matters for campaign planning. If you’re sending 3 campaigns per week to a 5,000-person list, that’s 60,000 emails per month just from campaigns (not counting flows). You need to make sure your plan tier supports your actual sending volume.
A quick note on a frustration merchants have raised in Shopify App Store reviews: some report that Klaviyo charges for contacts it then throttles or suppresses from campaign sends due to low predicted engagement. This makes list hygiene even more important. Clean your list regularly so you’re not paying for profiles that Klaviyo won’t email anyway.
Campaigns + Flows = A Complete Retention Strategy
Thinking about Klaviyo email marketing campaigns in isolation misses the bigger picture. Campaigns drive time-bound revenue spikes. A Black Friday campaign, a product launch, a flash sale. These create peaks on your revenue chart.
Flows compound daily. An abandoned cart flow recovers revenue around the clock. A welcome series converts new subscribers while you sleep. A post-purchase flow builds loyalty and drives repeat orders.
The brands generating 25-40% of their total store revenue from email and SMS are using both. Campaigns fill the calendar with planned revenue moments. Flows fill every gap in between with automated, behavior-triggered messages.
According to Klaviyo’s marketing mix report, 76.86% of ecommerce businesses place email marketing in their top 3 ROI-generating marketing channels. That ROI comes from the combination, not from campaigns or flows alone.

Frequently Asked Questions
What is a Klaviyo email marketing campaign?
A Klaviyo email marketing campaign is a one-time, manually scheduled email sent to a pre-built list or segment inside the Klaviyo platform. Unlike flows (which are automated), campaigns are planned broadcasts used for promotions, product launches, newsletters, and other time-sensitive messages.
What is the difference between a Klaviyo campaign and a flow?
Campaigns are one-time sends you schedule and control. Flows are automated sequences triggered by customer behavior (like signing up, abandoning a cart, or making a purchase). Campaigns typically generate 30-40% of email revenue while flows generate 60-70%, but both are essential for a complete strategy.
How many Klaviyo campaigns should I send per week?
Most D2C brands see the best results sending 2-3 campaigns per week to engaged segments. Going beyond 4-5 per week risks list fatigue and declining open rates. The key is varying your segments so the same subscribers aren’t receiving every single campaign.
What is a good click rate for Klaviyo campaigns?
The average click rate for Klaviyo campaigns in 2026 is 1.69%. Top-performing brands achieve around 3.38%. Click rate is a more reliable metric than open rate because Apple’s Mail Privacy Protection inflates open numbers.
How much does Klaviyo cost for email campaigns?
Klaviyo offers a free plan for up to 250 active profiles. Paid email plans start around $20/month and scale based on your profile count. Each tier includes a send limit of roughly 10x your active profiles.
Do Klaviyo campaigns work for small lists?
Campaigns become economically worthwhile once you have around 4,000 active profiles. Below that threshold, the time spent planning and building campaigns often isn’t justified by the revenue they generate. Smaller lists benefit more from growing the subscriber base and relying on automated flows.
Why are my Klaviyo campaign open rates so high?
If your open rates seem unusually high (above 40-50%), Apple Mail Privacy Protection is likely inflating the numbers. Apple pre-loads tracking pixels for its mail app users, registering “opens” that never actually happened. Focus on click rate and revenue per recipient instead.
Should I send campaigns to my entire list?
Almost never. Sending to your full, unsegmented list damages sender reputation, increases unsubscribes, and trains ISPs to treat your emails as low-engagement. Segmented campaigns generate 760% more revenue than non-segmented sends according to Klaviyo’s data.
