How much does Klaviyo cost?

You've been asking yourself this question for a while: how much will Klaviyo cost me exactly? And frankly, it's not that simple to calculate. Between recent price changes, different plans, hidden costs, and the fine print you always discover later... I'm going to explain it all clearly.

After analysis, businesses that switch to Klaviyo see an average ROI increase of 67%, but this requires implementing a comprehensive strategy. So, is it worth it? We're about to find out.

What changed in 2025 (and why it impacts your budget)

February 2025 marked a turning point for Klaviyo. On February 18, 2025, the platform implemented a new billing system that has some people grumbling. Previously, you only paid for the contacts you actually emailed. Now? You pay for all your "active profiles," even if you haven't sent them anything in months.

Specifically, if you have 5,000 subscribers but only send emails to 2,000 of them each month, you previously paid for 2,000. Today, it's 5,000. Ouch.

But there's good news (relatively speaking): Klaviyo has capped this increase at a maximum of 25%. So, no astronomical bad surprises all at once. And that's not all: they've added "flexible sending" and auto-downgrade features if your list shrinks.

Klaviyo vs. the Competition: The Price Matchup

Why Klaviyo costs more

Klaviyo is definitely not the cheapest option on the market. Compared to Mailchimp, which offers more affordable plans, Klaviyo focuses entirely on its advanced features.

Here's how they compare:

ROI: Where Klaviyo stands out

But here's the thing: email marketing generates an average ROI of 3600% (€36 for every €1 invested). And Klaviyo? Brands that switch to Klaviyo see a 46% increase in revenue over two years.

The largest e-commerce businesses generate over a quarter of their revenue through email, with an average revenue of 20 cents per email sent for companies with over €10M in annual revenue.

Klaviyo pricing in detail (2026 version)

The free plan: perfect for getting started

• €0  for up to 250 contacts
• 500 emails per month maximum
• 150 SMS/MMS credits included
• Basic features (automations, segmentation, analytics)

This is perfect if you're just starting out, but be careful: once you exceed 250 contacts, the free plan is over. And you can't go back, even if your list shrinks.

Paid plans: where it gets complicated

Email-only plan :

• Starting from €45/month for 1,001-1,500 active profiles
• 15,000 emails included
• No SMS (except 150 free credits)
• Email support

Email + SMS plan (recommended) :

• Starting from €60/month for 1,001-1,500 active profiles
• 15,000 emails included
• 1,250 SMS/MMS credits
• Priority support
• Brands with email + SMS see a 19% increase in their growth rate

Hidden costs you absolutely need to plan for

The SMS trap: the credit system

Klaviyo uses a credit system for SMS. An SMS in France costs approximately 1 credit, but MMS can cost up to 3 or 4. And here's the catch: these credits do not roll over to the next month! If you don't use them, you lose them.

Cost of additional credits:

• 1,250 credits: ~€15
• 2,500 credits: ~€25
• 5,000 credits: ~€45

Klaviyo includes operator fees in the credit price, which avoids surprises, but makes the final cost higher.

Automatic plan upgrades

Here's the thing many people discover too late: Klaviyo automatically changes your plan based on your number of active profiles. Your list grows? Your bill does too, automatically. Convenient for them, less so for your budget.

But good news since 2025: they've added auto-downgrade. If your list shrinks, your bill decreases the following month.

Additional options that weigh down the budget

• Marketing Analytics : €100/month minimum for 13,500 contacts (for advanced reports)
• Advanced Customer Data Platform : starting from €500/month for 100,000 profiles
• Reviews : €25/month for 250 orders to manage customer reviews
• Dedicated IP : price on request (necessary for large volumes)
• SMS short code:additional cost if you want a short number before reaching 30,000 contacts

Hidden fees that are often forgotten

• VAT : Klaviyo prices are exclusive of tax. Add 20% if you are in France
• Exchange fees : Klaviyo bills in dollars, which can create exchange rate fluctuations
• Agency setup fees : If you go through an agency, expect €500 to €2000 for initial setup
• Training : Expect €500 to €1500 to properly train your teams

How to calculate your real Klaviyo budget?

Step 1: Count your active profiles (not your total subscribers)

Active profiles are all those who can receive your emails, even if they never open anything. This includes:

• Confirmed subscribers
• Contacts who have purchased (even without subscribing to the newsletter)
• Unconfirmed contacts who have provided their email

Excluded from active profiles : unsubscribed and deleted addresses.

Step 2: Estimate your actual SMS needs

If you plan to do SMS marketing, calculate how many you will send per month. Some examples:

• Fashion e-commerce : 2-4 SMS per month per active contact
• Food e-commerce : 1-2 SMS per month
• Services: 1 SMS per month maximum

Don't forget that unused credits are lost!

Step 3: Anticipate growth (crucial!)

Your list will grow (at least, we hope so). Klaviyo will automatically upgrade you to the next plan. Plan for a 20-30% margin in your budget.

Rule of thumb : If you generate €50,000 in monthly revenue, your list will likely double in 12 months.

Step 4: Calculate the cost of integrations

Klaviyo integrates with over 350 tools, but some integrations have costs:

• Shopify Plus : free
• WooCommerce : free
• Magento : free
• Custom integrations : €1000 to €5000 depending on complexity

Fictional example: Sarah's case (organic cosmetics)

Let's take Sarah, who owns a cosmetics store with 3,500 active subscribers and generates €80,000 in monthly revenue:

Monthly costs:

• Basic Email + SMS plan : €95/month
• Additional SMS needs : €25/month (she uses SMS for product launches)
• Marketing Analytics : €100/month (essential for her detailed reports)
• Reviews : €25/month (to automatically collect reviews)
• VAT (20%) : €49/month
• Monthly total : €294
• Real annual budget : €3,800 (with planned growth)

Sarah's ROI : With 20-30% of her revenue generated by email, or €16,000 to €24,000 per month, her monthly ROI is 54x to 82x. Not bad!

Strategies to optimize your costs

Clean your lists regularly (more crucial than ever)

Since the pricing change, this has become vital. Delete inactive profiles older than 6 months. You'll pay less AND your engagement rates will improve.

Action plan to clean your database:

• Monthly: remove hard bounces
• Quarterly: remove inactive 6+ months
• Bi-annually: complete list audit

Utilize new flexibility features

• Auto-downgrade : Activate the option for your plan to automatically decrease if your list shrinks
• Flexible sending : For temporary peaks, use "flex" instead of permanently upgrading
• Temporary upgrades : Perfect for Black Friday or product launches

Optimize your SMS usage

• Focus on high-impact moments (abandoned carts, launches)
• Use email for nurturing, SMS for urgency
• Test the optimal number of SMS per month (often less than you think)

The "mix and match" alternative

If Klaviyo becomes too expensive, you can mix:

• Klaviyo  for complex e-commerce automations
• Yopto  for SMS
• Total : 30-50% savings on large volumes

But beware of false economies

Klaviyo generates on average 30x more revenue with its automations than with one-shot campaigns. Its automation and segmentation features can generate more revenue than savings from switching tools.

Concrete example : Switching from Klaviyo (€300/month) to Mailchimp (€100/month) to save €200, but losing €2000 in monthly revenue due to less powerful automations…

The real ROI of Klaviyo: the numbers that matter

How to calculate if it's worth it for you

Simple formula: Monthly revenue generated by email ÷ Monthly Klaviyo cost = ROI

Example:

• Monthly revenue: €100,000
• Email share: 25% = €25,000
• Klaviyo cost: €400
• ROI: 62x

If your ROI is greater than 10x, Klaviyo is clearly worth it. Between 5x and 10x, it's borderline. Below 5x, look elsewhere.

Use cases: when Klaviyo is (really) worth it

Klaviyo is perfect if:

✅You generate more than €10,000 in monthly revenue

• The cost becomes negligible compared to the revenue potential

✅You have complex buying cycles

• Sophisticated automations, long nurturing

✅You sell products with high repeat purchases

• Welcome flows: average €2.65 per recipient

✅You have a dedicated marketing team

• Klaviyo requires time to master

✅You want to push personalization

• AI and machine learning for granular personalization

Klaviyo will not be interesting for you if:

❌You're starting with less than €2,000 in monthly revenue

• The costs will weigh down your margin

❌You're just sending a simple newsletter

• You're paying for features you don't use

❌You don't have time to dedicate to setup

• Steeper learning curve than competitors

❌Your product isn't suitable for repeat purchases

• Automations lose their relevance

FAQ: All your questions about Klaviyo pricing

Q: Can I go back to the free plan if I drop below 250 contacts? A: No, once you've exceeded 250 contacts, you can't go back to the free plan, even if you drop below that number. 

Q: What happens if I exceed my plan? A: Klaviyo automatically upgrades you. You pay the prorated difference. Keep a close eye on your stats!

Q: Do SMS credits roll over? A: No. Unused credits are lost each month. Plan accordingly!

Q: How are overages billed? A: With the "flex" system, you pay the unit price of your current plan. Often more expensive than a permanent upgrade.

Q: Klaviyo vs Omnisend, which to choose? A: Omnisend is more affordable and simpler, Klaviyo is more powerful but more expensive. If you have a tight budget and basic needs: Omnisend. If you need complex automations: Klaviyo.

Q: Can I easily migrate to another tool? A: Technically yes, but you will lose behavioral data history. Omnisend offers free migration from Klaviyo.

Q: Are integrations really free? A: Klaviyo offers over 350 free native integrations, but custom integrations can be expensive (€1000 to €5000).

The final verdict: Is Klaviyo still worth it in 2025?

After this in-depth analysis, here is our transparent conclusion:

Klaviyo probably remains the most powerful tool for e-commerce email marketing.

Our final advice

If you're hesitant, start with a cheaper tool (Omnisend, Brevo) to learn the basics. Once email generates 15-20% of your revenue, switch to Klaviyo. You will then have the budget AND the skills to profit from it.

And most importantly: clean your lists regularly. With the new pricing system, it has become crucial. An inactive contact now costs you money every month!

The realistic budget for 2026: expect €300 to €800/month for an e-commerce business generating €50k to €200k in monthly revenue.

There you have it, you now have all the information to precisely calculate what Klaviyo will cost you. And most importantly, to decide if it's worth it for your business.
