Klaviyo Agency Pricing in 2026: What Agencies Actually Charge

You will also see $300 a month quoted, and $18,000 a month quoted, for what reads on the website like the same service. They are not the same service. At the bottom you are buying scheduled sends against a template library. At the top you are buying a five-person senior team. The published rate cards show the difference plainly, so here they are side by side.

Below roughly $1,500 a month the published market is production work, priced per output. That is a legitimate purchase. It is a different purchase from someone owning your churn curve, and the rate cards are honest about which one they are selling.

SourcesFree tier from Klaviyo’s own pricing page, checked September 2026 · ladder and SMS credit rates from Carly’s Klaviyo pricing breakdown, 15 July 2026 · corroborated at 5,000, 10,000 and 50,000 profiles by Retainful, 6 April 2026. Monthly, email plan, US pricing.

On the email plan, sends are bundled into your profile tier, not billed one by one. So the honest answer to “what does it cost to send 10,000 emails” is that it depends on how many profiles you store, not how many messages you send.

Budget the platform and the program in one spreadsheet, not two. A brand paying for 50,000 stored profiles it never emails is spending about $8,600 a year on the wrong line before the agency conversation even starts.

• 01How many emails and builds do I get in a month, in writing?“Ongoing optimization” is not a deliverable. If a proposal cannot be reduced to a countable monthly output, it will shrink the moment the agency gets busy.
• 02Who writes, who designs, who builds, and how many accounts do they carry?The pitch team is not always the delivery team, and seniority is what you are actually paying for. A senior operator on six accounts and one on twenty are not the same purchase.
• 03What do you report on, and against which attribution window?The window is a setting inside Klaviyo. Widening it can raise a reported number without changing your bank balance. Agree it before month one, not during the first argument.
• 04What happens to failed payments and cancellations?For a subscription brand this is the cheapest revenue in the account, because you already earned it. If it is not in the proposal, the proposal is a campaign calendar.
• 05Is the Klaviyo bill inside or outside this number?It is almost always outside, and on the published ladder it runs from about $20 to $720 a month before SMS. Get both invoices into the same forecast.
• 06Who owns the account, the templates and the data if we leave?The answer should be you, immediately, with no export fee and no hostage period. Get it in the contract, not the sales call.
• 07What is the notice period, and is there a minimum term?Long lock-ins protect an agency from its own performance. Month to month keeps the numbers doing the retaining.
• 08Show me a named case study in my category, with numbers.Anonymous “a leading supplement brand” results cannot be checked. Named ones can be questioned, and the client can be asked directly.

The pairing that tends to win is neither one nor the other: in-house owning brand, product knowledge and the calendar, with an agency owning architecture and economics. We wrote the longer version in agency vs in-house.

The full library is at case studies, and the framework underneath them is the LTV Parthenon.

Eight platforms, eight independent write-ups. That is the check worth running on any agency you are quoting against: ask who else has published their numbers.
