How Much Does a Klaviyo Agency Cost? Real Pricing Breakdown

I run a Klaviyo agency. I'm going to tell you exactly what agencies charge, why the range is so wide, and how to figure out whether what you're paying (or about to pay) is reasonable.

This is the article I wish existed when I was on the brand side trying to hire help with email. Every agency website says "starting at" and then makes you book a call to find out the real number. I'll give you the real numbers right now.

The Short Answer

Most Klaviyo agencies charge between $2,000 and $15,000 per month for ongoing management. Some charge less, some charge more. The typical eCommerce brand doing $1M-$10M in annual revenue will pay somewhere between $3,000 and $8,000/month for a competent agency.

But that range is almost meaningless without context. A $3,000/month agency and a $10,000/month agency might deliver identical work. Or the $10,000 agency might be worth ten times more than the $3,000 one.

Let me break down what actually determines the price.

The Four Pricing Models

Model 1: Flat Monthly Retainer

Range: $2,000-$15,000/month

This is the most common model. You pay a fixed monthly fee, and the agency handles your email and SMS marketing within a defined scope.

What's usually included:

• Flow setup and optimization (automations)
• Campaign strategy, design, copywriting, and sending (usually 3-8 campaigns per month)
• List management and segmentation
• Monthly reporting
• Basic A/B testing

What's usually NOT included:

• Custom template design (one-time fee, typically $500-$2,000 per template)
• SMS marketing (often an add-on, $500-$2,000/month extra)
• Advanced integrations or custom API work
• Paid media coordination

Who this works for: Brands that want predictable costs and a defined scope. Most eCommerce brands between $500K and $20M in revenue end up on a flat retainer.

Model 2: Percentage of Revenue

Range: 10-20% of email/SMS revenue attributed to the agency's work

Some agencies charge a percentage of the revenue they generate through email and SMS. So if your Klaviyo channels drive $100K/month and the agency charges 15%, you pay $15,000.

The upside: Agency incentives are aligned with your revenue. They make more when you make more.

The downside: Attribution is messy. Klaviyo's default attribution is generous — it credits revenue to email for anyone who received an email and purchased within a certain window, even if they would have bought anyway. So the "revenue driven" number that determines your bill might be inflated.

Also, as your list grows and your business scales, this model gets expensive fast. A brand doing $50K/month in email revenue pays $7,500/month at 15%. When that grows to $200K/month, they're paying $30,000/month for what might be the same amount of work.

Who this works for: Brands just getting started with email marketing who want low risk. The percentage model means you pay less when revenue is low. But negotiate a cap, or you'll regret it once things scale.

Model 3: Project-Based

Range: $3,000-$25,000 per project

This is for specific, defined work:

• Full Klaviyo setup from scratch: $5,000-$15,000
• Flow rebuild (all core automations): $3,000-$10,000
• Template design system: $2,000-$5,000
• Audit and strategy document: $1,500-$5,000
• Migration from another platform: $3,000-$8,000

Who this works for: Brands with an in-house team that can handle ongoing management but need expert help for specific projects. Also good for a one-time setup if you're just getting started on Klaviyo.

Model 4: Hourly Consulting

Range: $150-$400/hour

Some agencies (and a lot of independent consultants) charge by the hour. Senior Klaviyo specialists typically charge $200-$350/hour.

Who this works for: Brands that need occasional guidance but not full management. "We need someone to review our flows twice a quarter" kind of thing.

What You Should Expect at Each Price Point

Here's a blunt breakdown of what you actually get:

$1,000-$2,000/month (Budget Tier)

Reality check: At this price, you're getting a freelancer or a very junior team. Nothing wrong with that for certain situations.

What you'll get:

• 2-4 campaigns per month
• Basic flow setup (welcome, cart abandonment, maybe post-purchase)
• Simple templates
• Monthly performance email (not really a "report")

What you won't get:

• Custom strategy based on your data
• Advanced segmentation
• Dedicated account manager
• Proactive optimization
• A/B testing program

Best for: Pre-revenue or early-stage brands under $500K/year that just need the basics running.

$3,000-$5,000/month (Mid-Tier)

This is where most brands should start. You get a real team with real expertise.

What you'll get:

• 4-8 campaigns per month with proper segmentation
• Full flow architecture (8-12 core flows)
• Custom template designs
• Monthly strategy calls
• Regular A/B testing
• Detailed monthly reporting with revenue attribution
• Segmentation strategy
• Deliverability monitoring

What you might not get:

• SMS management (usually an add-on)
• Custom integrations
• Daily Slack access to your team

Best for: Brands doing $500K-$5M/year that want to build email into a serious revenue channel.

$5,000-$10,000/month (Premium Tier)

What you'll get (everything above, plus):

• 8-12+ campaigns per month
• Advanced segmentation and personalization
• SMS strategy and management
• Dedicated senior strategist
• Weekly or bi-weekly strategy calls
• Custom reporting dashboards
• Proactive A/B testing program with documented learnings
• Cross-channel coordination (how email fits with ads, content, etc.)
• Priority Slack or messaging access

Best for: Brands doing $5M-$20M/year where email/SMS is a primary revenue driver.

$10,000-$15,000+/month (Enterprise Tier)

What you'll get:

• Full-service retention marketing
• Large team: strategist, designer, copywriter, developer
• Multiple Klaviyo accounts (if you have multiple brands)
• Advanced personalization and dynamic content
• Integration with loyalty programs, reviews, subscription platforms
• Custom analytics and attribution modeling
• Executive-level reporting

Best for: Brands doing $20M+ where the email program is complex, multi-brand, or international.

The Hidden Costs Nobody Mentions

Beyond the agency fee, budget for:

Klaviyo platform cost: $20/month for up to 500 contacts, scaling to $1,000+/month for 100K+ contacts. This is separate from what you pay the agency.

SMS costs: Klaviyo charges per SMS sent. In the US, expect $0.01-$0.02 per SMS. A brand sending 50K texts/month pays $500-$1,000 in SMS credits on top of everything else.

Onboarding fee: Many agencies charge a one-time setup fee of $1,000-$5,000 for initial flow builds, template design, and account configuration. Some fold this into the first 2-3 months of a higher retainer.

Template design: If your agency doesn't include custom design, expect $500-$2,000 per template for a professional designer.

Content/photography: Agencies can write copy and build emails, but they need product photos, lifestyle images, and brand assets. If you don't have these, that's an additional cost.

How to Know If You're Overpaying

Here's a simple framework: look at your email/SMS revenue as a percentage of total revenue, and compare it to what you're spending on the agency.

Healthy benchmarks for eCommerce:

• Email and SMS should drive 25-40% of total revenue (including flows and campaigns)
• Your agency cost should be 5-15% of the revenue they're driving through email/SMS

So if your brand does $500K/month total and email drives $150K of that (30%), a $5,000/month agency fee is about 3.3% of email revenue. That's a great deal.

If your brand does $100K/month total and email drives $15K of that (15%), and you're paying $5,000/month — that's 33% of email revenue going to the agency. The email program isn't performing well enough to justify that spend, OR the agency isn't generating enough revenue.

Red flags that you're overpaying:

• Email revenue has been flat for 3+ months despite "optimization"
• The agency can't show you flow-level and campaign-level revenue breakdowns
• They're sending the same content to your entire list
• You haven't had a strategy conversation in over a month
• Your flows haven't been updated since they were first built

How to Know If You're Underpaying

This is the less obvious problem. If you're paying $1,500/month and getting exactly what you pay for, you might be losing tens of thousands in potential email revenue.

Signs you need to invest more:

• Email drives less than 20% of total revenue
• You only have 2-3 basic flows running
• Campaign frequency is less than 1x/week
• No A/B testing is happening
• No SMS program
• Your list is growing but engagement is dropping
• You've never had a deliverability audit

A brand paying $1,500/month for basic email management that generates $10K/month in email revenue might think they're getting a good deal. But if a $5,000/month agency could grow that to $40K/month, the $1,500 "bargain" is actually costing $26,500/month in lost revenue.

What to Ask Before You Hire

Questions that separate good agencies from mediocre ones:

1. "Can you show me results from brands similar to mine?" Not just revenue numbers — flow-level performance, campaign strategies, specific improvements they made.

2. "Who will actually be working on my account?" The person on the sales call is often not the person doing the work. Ask to meet the strategist and the person building your emails.

3. "How do you measure success?" If they say "open rates and click rates," run. If they say "revenue per recipient, flow revenue, campaign revenue, list growth rate, and deliverability metrics," that's better.

4. "What does month 1 look like?" A good agency has a structured onboarding: audit, strategy document, flow architecture plan, template design, then execution. If they just start "sending emails," there's no strategy behind it.

5. "How do you handle attribution?" Smart agencies know Klaviyo's default attribution is generous. They should be able to talk about attribution windows, how they separate flow vs. campaign revenue, and how they account for revenue that would have happened without email.

6. "What's your approach to deliverability?" If they don't bring this up proactively, they're not thinking about it. Deliverability is the foundation of everything. If your emails don't land in the inbox, nothing else matters.

Our Pricing (Being Transparent)

Since I'm writing this article, I might as well be direct about what we charge at GOSH Digital.

We work with eCommerce brands typically doing $1M-$30M in annual revenue. Our Klaviyo management retainers range from $3,500 to $12,000/month depending on the size of the account, number of flows, campaign volume, and whether SMS is included.

We also do project-based work — full Klaviyo setups, flow rebuilds, and audits — starting at $4,000.

We've driven over $70M in revenue across our client portfolio. Klaviyo Gold Partner. We actually do the work ourselves — no white-labeling, no outsourcing to a freelancer you've never met.

If you want to know exactly what it would cost for your brand, book a call. I'll be straight with you about whether we're the right fit and what the investment looks like. If we're too expensive for where you are right now, I'll tell you that too, and I'll point you in the right direction.

The Bottom Line

A Klaviyo agency should pay for itself. If it doesn't — if email revenue isn't meaningfully higher than what you're paying — something is broken.

The right agency at the right price point should deliver a 5-10x return on your investment within the first 90 days. Not because of some magical formula, but because most brands have so much low-hanging fruit in their email program that a competent team can find revenue quickly.

Don't cheap out on the thing that drives 25-40% of your revenue. And don't overpay for an agency that sends pretty emails but can't show you the numbers.
