How Much Does Klaviyo Cost in 2026? Real Pricing, Hidden Fees, and a Cost-Cutting Playbook

TL;DR: Klaviyo starts free for 250 profiles, then runs about $20/mo at 500 profiles, around $150/mo at 10,000, and roughly $720/mo at 50,000 on email-only plans. SMS is billed per credit on top. Real brands average around $1,500/mo all-in once SMS and add-ons stack. Your bill is driven by active profiles, not list size, so list hygiene is the biggest lever you control.

What it actually costs and why it surprises people

So how much does Klaviyo cost? For most Shopify brands, the honest answer is "more than the pricing page suggests." The headline number tracks your active profiles, but the real bill stacks SMS credits, add-ons, and the consequences of a bloated list on top of that base tier. A store paying for a 10,000-profile plan can easily spend two or three times the sticker price once everything is added in.

Klaviyo's free plan covers 250 active profiles, 500 email sends a month, and 150 SMS credits. That's fine for testing. The moment you grow past it, you move to paid tiers that climb with your profile count. Below, you'll get the real numbers, the active-profile billing mechanics that trip people up, a true all-in cost for a realistic brand, and a playbook to bring the bill back down. Across the Shopify stores we manage at CartStrings, the brands with the cleanest lists almost always pay the least per dollar of revenue.

How much does Klaviyo cost per month?

Klaviyo's monthly cost scales with your active (emailable) profiles. Email-only plans run about $20/mo at 500 profiles, $30 at 1,000, $70 at 5,000, around $150 at 10,000, and roughly $720 at 50,000. Email plus SMS starts near $35/mo. SMS credits are billed separately on top of whichever tier you land on.

Here's the email-plan breakdown so you can find your tier fast:

• 250 active profiles: Free (500 email sends/mo, 150 SMS credits)
• 500 profiles: about $20/mo (entry paid tier)
• 1,000 profiles: about $30/mo
• 5,000 profiles: about $70/mo
• 10,000 profiles: around $150/mo (cited as $130 to $150 across sources)
• 20,000 profiles: about $375/mo
• 50,000 profiles: about $720/mo

These figures line up with third-party pricing breakdowns from Omnisend and others. Klaviyo adjusts tiers periodically, so confirm your exact number at klaviyo.com/pricing before you budget. One more thing for enterprise brands: once you're spending $10,000/mo or more, Klaviyo moves you onto its Klaviyo One contract, which adds a roughly 20% surcharge.

How much does Klaviyo cost for 10,000 contacts?

Klaviyo costs around $150/mo for 10,000 active email contacts. You'll see this quoted anywhere from $130 to $150 depending on the source and the date, since Klaviyo tweaks its tiers. Add SMS or paid add-ons and your real spend at that profile count climbs well above the base email tier.

That 10,000-contact tier is where most growing Shopify brands sit, and it's also where the comparison shopping starts. For context, marketer Chase Dimond's breakdown puts Omnisend around $132/mo and Klaviyo around $150/mo at 10,000 contacts. Close on paper. The gap that matters is what each platform does with those contacts, and Klaviyo's flow engine and Shopify integration are why most serious stores still pick it.

Why active-profile billing inflates your bill

This is the part that catches store owners off guard. As of February 18, 2025, Klaviyo bills on active profiles, not just subscribed contacts. An active profile is any emailable profile, and that includes people captured at checkout who never actually opted into marketing.

So every time a shopper enters their email during Shopify checkout, that profile can become billable, even if they never ticked the subscribe box. Multiply that across months of orders and your profile count quietly balloons. Worse, Klaviyo does not auto-downgrade your plan when your active count drops. If you cross a tier, you keep paying for it until you manually move down.

There's a 25% price-increase cap that protects accounts that existed before the February 2025 switch, which softens the blow for legacy users. New accounts get no such cushion. Either way, the lesson is the same: your list grows whether you manage it or not, and the bill follows.

The 90-day re-suppression trap

Here's a costly detail buried in the active-profile rules. Once you unsuppress a profile, you can't re-suppress it for 90 days. That's three full billing cycles you pay for, even if you realize the profile was dead weight the day after.

Picture this. You run a win-back campaign and unsuppress 8,000 dormant profiles to give them one last shot. Almost none re-engage. You'd love to suppress them again next week to drop a pricing tier. You can't. Those 8,000 profiles count toward your active total for 90 days, and if they push you from the 20,000 tier (about $375) up to a higher one, you eat the difference for a quarter. Plan unsuppressions deliberately, not on impulse.

How much does Klaviyo SMS cost?

Klaviyo SMS is billed by credits on top of your plan. In the US, one credit runs roughly $0.0092 to $0.012, and one credit sends one standard text segment. Messages over 160 characters cost 2 credits, MMS costs 3 credits, and international sends multiply (the UK is 5x, Canada is 3x).

That credit math is where SMS budgets blow up. A long promo text with an image isn't one credit, it's three. Send that MMS to 10,000 US subscribers and you've spent roughly 30,000 credits, or around $300 for a single send. International audiences cost several times more per message. SMS is one of the highest-ROI channels when it's done right, but you have to budget it as a real line item, not a rounding error.

What does Klaviyo really cost all-in for a 25k brand?

Once you add SMS and common add-ons to the base tier, a realistic mid-size brand pays far more than the email-plan number. Stacking SMS credits, Reviews, and analytics on top of a 20,000 to 25,000 profile tier pushes a typical store toward four figures a month. Real-world accounts average around $1,500/mo all-in.

Let's build the number for a brand sitting around 25,000 active profiles:

• Base email + SMS plan: roughly $400 to $500/mo for the profile tier
• SMS credits: easily $200 to $500/mo depending on send volume and message length
• Reviews add-on: about $25/mo per add-on pricing
• Marketing Analytics: about $100/mo
• CDP: about $500/mo once you hit 100k profiles (not yet relevant at 25k, but it's coming)

Add those up and you're comfortably in the $800 to $1,300/mo range before anyone gets fancy. That's why analyses of real accounts land on roughly $1,500/mo average, with a range of about $150 to $3,500/mo. The wide spread comes down to two things: how disciplined the brand is about list hygiene, and how heavily it leans on SMS and add-ons.

Is Klaviyo worth the cost?

For Shopify brands doing $500k+ a year, yes. Klaviyo regularly drives a meaningful share of total store revenue, and most accounts see a 30x to 50x return on the platform spend. The cost only feels high when flows are half-built and the list is full of dead profiles you're paying to store.

The revenue case is lopsided in your favor. Klaviyo's own benchmark data shows flows drive 41% of email revenue from just 5.3% of sends. That's automated revenue working while you sleep, off a tiny fraction of your send volume. Across the stores we manage at CartStrings, well-built automations and consistent campaigns typically produce 32% of total revenue from email, with a 39% open rate and 99.8% inbox delivery.

So the platform fee isn't really the question. The question is whether your account is set up to earn 30x to 50x back on it. If your flows are thin or your deliverability is shaky, you're paying Klaviyo's price without collecting Klaviyo's return. A Klaviyo audit is the fastest way to find out which side of that line you're on.

How do I lower my Klaviyo bill?

Lower your Klaviyo bill by shrinking your active profile count and turning on the auto-downgrade toggle. Build a sunset flow to suppress chronic non-openers, run a bulk suppression of dead profiles, and let Klaviyo automatically move you to a cheaper tier when your count drops. List hygiene cuts active profiles 10% to 25% for most stores.

Here's the playbook, in order:

• Build a sunset flow. A sunset flow automatically suppresses people who haven't opened or clicked in a set window (90 to 120 days is common). It protects your sender reputation and trims your billable count at the same time.
• Run a one-time bulk suppression. Segment everyone who hasn't engaged in six-plus months and suppress them in bulk. Combined with a sunset flow, list cleaning cuts active profiles 10% to 25%.
• Turn on auto-downgrade. Klaviyo won't drop your plan automatically by default. Find the auto-downgrade setting in your billing area and enable it so a smaller list actually means a smaller bill.
• Watch your checkout captures. Since non-opted-in checkout profiles count as billable, keep an eye on how fast that pool grows and suppress the truly cold ones.
• Budget SMS by credit, not by send. Keep promo texts under 160 characters when you can, and reserve MMS for sends where the image truly earns its 3-credit cost.

One caution: don't unsuppress profiles casually, because the 90-day re-suppression lock means an impulsive win-back can keep you on a higher tier for a full quarter. Clean deliberately. Your bill, and your inbox placement, both improve when your list reflects people who actually want to hear from you. If you'd rather not manage this yourself, our popups and capture work focuses on growing the right profiles, the ones that convert instead of just inflating your count.

The bottom line on Klaviyo pricing

Klaviyo costs nothing up to 250 profiles, about $150/mo at 10,000, and roughly $720/mo at 50,000 on email, with SMS and add-ons stacked on top. Real brands average around $1,500/mo all-in. The number you actually pay is mostly within your control, because it's driven by active profiles, and active profiles are driven by list hygiene.

Manage the list, watch your checkout captures, budget SMS as a real line item, and turn on auto-downgrade. Do that, and Klaviyo stays one of the highest-ROI tools in your stack instead of a creeping monthly surprise. If your bill has been climbing and you're not sure where the waste is, a Klaviyo audit will show you exactly what's leaking, or you can book a call and we'll walk through it with you.

Frequently Asked Questions

Is Klaviyo free?

Yes, Klaviyo has a free plan that covers up to 250 active profiles, 500 email sends per month, and 150 SMS credits per month. It's enough to test the platform or run a very small store. Once you grow past 250 profiles or need more sends, you move to paid tiers that scale with your active profile count.

Why did my Klaviyo bill go up?

Most surprise increases come from active-profile billing. Since February 2025, Klaviyo counts every emailable profile, including shoppers captured at checkout who never opted into marketing, so your billable count grows with each order. Klaviyo also doesn't auto-downgrade your plan when your count drops, so you keep paying for a higher tier until you manually move down or turn on auto-downgrade.

How much does Klaviyo cost for 10,000 contacts?

Around $150 per month on an email-only plan, though you'll see it quoted between $130 and $150 depending on the source and current pricing. SMS credits and add-ons like Reviews or Marketing Analytics are billed on top, so your real spend at 10,000 contacts is usually higher than the base tier alone.

Is Klaviyo cheaper than Mailchimp or Omnisend?

At 10,000 contacts, Klaviyo (around $150/mo) is roughly comparable to Omnisend (around $132/mo) and similar to Mailchimp on price. The difference is what you get for it. Klaviyo's flow automation and deep Shopify integration typically drive more revenue per contact, which is why most established e-commerce brands choose it even when a competitor is a few dollars cheaper.

How much does Klaviyo SMS cost?

US SMS runs about $0.0092 to $0.012 per credit, where one credit sends one standard text segment. Messages over 160 characters cost 2 credits, MMS costs 3 credits, and international sends cost more (the UK is 5x and Canada is 3x per message). Budget SMS as its own line item, since a single MMS blast to a large list can cost a few hundred dollars.
