Klaviyo Pricing Explained: What You'll Actually Pay in 2026

TL;DR: Klaviyo pricing is based on active profiles, not emails sent. Paid plans start at $20 per month for 500 profiles, hit $150 at 10,000, and $720 at 50,000. SMS, reviews, and analytics all cost extra. The fastest way to cut your bill: suppress unengaged contacts before your billing date and turn on auto-downgrade. This guide breaks down every tier and every hidden cost.

Klaviyo pricing confuses more store owners than any other part of the platform. The website says plans start at $20 per month. Then your first real invoice lands at $150, $400, or more, and you're left wondering what you're actually paying for.

Here's the short version: you're paying for contacts, not sends. Every profile in your account that can receive an email counts toward your bill, even people you haven't emailed in a year. Since Klaviyo changed its billing model in February 2025, thousands of stores have seen their costs jump without adding a single subscriber.

At CartStrings, we manage Klaviyo accounts for Shopify brands every day, and billing questions come up on almost every audit. So this guide covers what each tier costs in 2026, how SMS credits work, why your bill went up, and the exact steps that bring it back down.

How Klaviyo Pricing Works

Klaviyo charges you based on the number of active profiles in your account. Not email volume. Not campaigns sent. Profiles.

There are three core plans, according to Klaviyo's official pricing page:

• Free: up to 250 active profiles, 500 email sends per month, and 150 mobile messaging credits. Email support lasts 60 days, then you're on community support only.
• Email: starts at $20 per month for 251 to 500 profiles and scales up from there.
• Email + SMS: your email plan plus a mobile credit bundle, starting around $15 per month extra for 1,250 credits.

Every paid email plan includes monthly sends equal to roughly 10 times your profile count, a limit confirmed in Klaviyo's billing documentation. A 10,000-profile account can send about 100,000 emails per month. Most stores never hit that ceiling.

One thing many buyers miss: the feature set is identical at every tier. You get the same flows, segmentation, predictive analytics, and integrations at $20 per month as you do at $2,300 per month. The price climbs because your list grows, not because you unlock anything new.

What Counts as an Active Profile in Klaviyo?

An active profile is any contact who can be emailed through Klaviyo, regardless of consent status. That includes subscribers, plus shoppers who typed their email at checkout but never opted in to marketing. Suppressed profiles, hard bounces, and deleted contacts don't count toward your bill.

This definition comes straight from Klaviyo's active profile documentation, and it's the single biggest source of billing surprises. Someone who abandoned a checkout 14 months ago and ignored every email since is still a billable profile until you suppress them.

The good news: Klaviyo never charges for suppressed profiles. They stay in your account with all their data, they just can't receive marketing emails and don't count toward your tier. That's the lever almost every cost-reduction tactic pulls on.

Klaviyo Pricing Tiers: What You'll Pay at Every List Size

Here's what the email plan costs at common list sizes, based on tier data verified against Klaviyo's pricing page in 2026:

• Up to 250 profiles: free
• 251 to 500: $20 per month
• 501 to 1,000: $30 per month
• 1,501 to 2,500: $60 per month
• 3,501 to 5,000: $100 per month
• 6,501 to 10,000: $150 per month
• 15,001 to 20,000: $375 per month
• 20,001 to 25,000: $400 per month
• 45,001 to 50,000: $720 per month
• 95,001 to 100,000: $1,380 per month
• 200,001 to 250,000: $2,300 per month

Above 250,000 profiles, you move to custom billing with Klaviyo's sales team.

Notice how the jumps get steeper in the 10,000 to 15,000 range. Tiers narrow to 500-profile increments there, so a list that's growing fast can trigger an upgrade every few weeks. Klaviyo auto-upgrades you when you cross a threshold. It does not auto-downgrade you when your list shrinks unless you switch that setting on, a default that costs many stores real money every month.

Also budget for add-ons if you need them. Reviews starts at $25 per month at 250 orders, Marketing Analytics starts at $100 per month, and the advanced data platform starts at $500 per month. None of these are included in the base plan.

How Much Does Klaviyo SMS Cost?

Klaviyo SMS runs on a credit system, starting at about $15 per month for 1,250 credits on top of your email plan. One US text costs 1 credit for up to 160 characters. A US MMS costs 3 credits. Credits reset monthly and unused credits don't roll over.

The mechanics matter here. Per Klaviyo's mobile credit documentation, credit usage varies by message type and destination country. An MMS to Australia can cost 15 credits. Add an emoji to a text and your character limit drops from 160 to 70 before the message costs double.

In practice, US SMS credits work out to roughly $0.009 to $0.012 per message depending on volume. Carrier fees are baked into the credit price, so there are no surprise per-message charges on top.

If you're weighing whether SMS is worth adding, our guide to Klaviyo SMS marketing for Shopify covers the setup and the flows that actually pay for the credits.

The February 2025 Billing Change (and Why Your Bill Went Up)

On February 18, 2025, Klaviyo switched from billing based on the contacts you actually emailed to billing based on every active profile in your account. The change was announced in January 2025 and applied to all accounts.

The math hit hard for stores with big, lazy lists. Say you had 20,000 total contacts but only emailed an engaged segment of 8,000. Before the change, you paid the 8,000-profile rate of $150 per month. After it, you paid the 20,000-profile rate of $375 per month. Same list, same sending habits, $225 more per month.

Three details from that change still shape your bill today:

• Auto-upgrade is on by default and has no opt-out. Cross a tier threshold and your next invoice goes up.
• Auto-downgrade is off by default. You have to enable it under Settings, then Billing, then Preferences.
• The 90-day suppression lock: once you unsuppress a contact, you can't suppress them again for 90 days. Reactivate a dormant profile and you're paying for them for three billing cycles minimum.

Klaviyo did soften the blow with a 25% cap on increases for existing accounts, applied as an ongoing appreciation discount for accounts that stay on eligible plans. But new accounts pay full freight from day one.

How Do You Lower Your Klaviyo Bill?

Suppress contacts who haven't engaged in 180 days, turn on auto-downgrade in your billing settings, and run a sunset flow before suppressing anyone. Suppressed profiles cost nothing, so cleaning your list directly drops you into a lower tier. Audit paid add-ons quarterly and cancel any that aren't earning their fee.

Here's the sequence we use across the Shopify stores we manage at CartStrings:

• Enable auto-downgrade first. It takes 30 seconds and guarantees you stop overpaying in months when your list shrinks.
• Run a sunset flow before suppressing. Send two or three re-engagement emails to contacts inactive for 120+ days. Keep whoever clicks. Suppress the rest. Our Klaviyo sunset flow guide walks through the exact setup.
• Time your suppressions. Check your billing date, then suppress unengaged contacts two days before it so they're out of the count when the cycle renews.
• Import selectively. Migrating from another platform? Only bring contacts you have a real plan to email. Every imported profile is billable immediately.

A leaner list doesn't just cost less. It improves deliverability, which lifts the revenue side of the equation too.

Is Klaviyo Worth the Cost?

For most Shopify brands doing real volume, yes, and the math isn't close. Klaviyo's own benchmark data shows automated flows generate nearly 41% of total email revenue from just 5.3% of sends, with revenue per recipient around 18 times higher than campaigns. The platform averages $0.11 in revenue per email recipient, and well-run accounts do far better.

The benchmark we hold clients to: email should drive 20 to 30% of total store revenue. Across the Shopify stores we manage at CartStrings, we average 32% email-attributed revenue. At that level, a $400 per month Klaviyo bill on a store doing $200k per month is a rounding error. If you want to see how that target breaks down, read our guide on how much revenue email should generate for your store.

When Klaviyo isn't worth it: you're under 1,000 profiles and not yet selling consistently, or you're paying for 30,000 profiles while emailing 8,000. The first problem fixes itself with growth. The second is a list hygiene problem, not a platform problem, and it's exactly what a Klaviyo audit is built to catch.

Bottom line: Klaviyo pricing rewards lean, engaged lists and punishes neglected ones. Clean your list, enable auto-downgrade, and make your flows carry the load. Do that, and the platform pays for itself many times over. If you'd rather have someone find the wasted spend for you, book a call and we'll go through your account together.

Frequently Asked Questions

How much does Klaviyo cost per month?

Klaviyo's email plan starts at $20 per month for up to 500 active profiles. Typical costs are $60 at 2,500 profiles, $150 at 10,000, $400 at 25,000, and $720 at 50,000, per Klaviyo's pricing page. SMS, reviews, and analytics are billed separately.

Does Klaviyo charge for unsubscribed or suppressed contacts?

No. Suppressed profiles, unsubscribes, and hard bounces don't count toward your active profile total, per Klaviyo's suppression documentation. You only pay for contacts who can currently receive marketing emails. That's why suppressing unengaged contacts is the fastest way to drop a pricing tier.

Does Klaviyo offer an annual discount?

No. Self-serve plans are billed monthly with no annual discount as of 2026. Accounts spending roughly $2,000 or more per month can negotiate custom contracts with Klaviyo's sales team, and enterprise agreements sometimes include modest discounts.

What happens if I go over my active profile limit?

Klaviyo won't block sends or stop you from adding contacts. You'll get a notification, and your account auto-upgrades to the next tier at the start of your following billing cycle. There's no per-contact overage fee, but there's also no automatic downgrade unless you enable it in billing preferences.

Is the Klaviyo free plan enough to start?

It works for brand-new stores. You get 250 active profiles, 500 email sends per month, and 150 mobile credits, with full access to flows and segmentation. Any store with steady traffic outgrows it within weeks, at which point the $20 and $30 tiers are an easy step up.
