I run a Klaviyo agency, so I'll just tell you what this actually costs instead of making you book a discovery call to find out.
A Klaviyo agency runs anywhere from $2,000 to $20,000 per month. Most ecommerce brands doing real volume end up somewhere in the $5,000 to $10,000 range. The number alone doesn't mean much though, because what you get at each price point varies wildly.

This is everything I know about agency pricing, what the different tiers look like, what the total cost of email marketing really adds up to, and how to tell if an agency is worth the money or not.
4 Klaviyo Agency Pricing Models
There are really only four ways agencies price their services. Here's what each one looks like:
1. Fixed Monthly Retainer
Most common model and the one that makes the most sense for most brands. The agency scopes out what you need, sets a flat monthly price, and that's what you pay.
This is how Threadpoint works. We define a scope that's specific to each client and lock in a price. The nice thing about fixed pricing is that as your business grows, the agency fee becomes a smaller and smaller percentage of revenue. You're not getting penalized for scaling.

Typical range: $3,000 to $15,000/month depending on scope and brand size.
2. Tiered Pricing
Some agencies set up bronze/silver/gold type packages based on your revenue or list size. You bump up tiers as your business grows.
This can work fine, but it creates a weird incentive. The agency is financially motivated to push you into a higher tier, and sometimes the scope difference between tiers doesn't really justify the price jump.
Typical range: $2,000 to $12,000/month across 3-4 tiers.
3. Revenue Share / Percentage of Revenue
The agency takes a percentage of whatever revenue gets attributed to email. Sounds great on paper ("we only win when you win"), but email attribution is messy and this model basically incentivizes the wrong behavior.
Think about it: a customer clicks a Meta ad, visits your site, abandons their cart, gets a Klaviyo abandoned cart email, and then buys. Under last-click attribution, email gets all the credit. So a revenue share agency is financially motivated to blast discount emails and claim credit for sales that would've happened regardless.
Typical range: 5% to 15% of email-attributed revenue.
4. Hourly Pricing
Pretty rare in the retention space, mostly freelancers and smaller shops. The issue is predictability - you never really know what your monthly bill will look like, and the incentive structure rewards slow work over efficient work.
Typical range: $75 to $250/hour.
For most brands, fixed monthly retainer with a custom scope is the way to go. You know what you're paying, the agency knows what they're delivering, and it gets relatively cheaper as you grow.
What You're Getting at Each Price Point
The price range is huge, so here's what you should realistically expect at each level:
$2,000 to $4,000/Month
At this price, you're getting reactive service. Copy-paste flow templates, maybe 2-3 campaigns per week, a monthly report showing your open rate. That's pretty much it.
There's no custom segmentation strategy, no real A/B testing program, no one digging into your customer data to figure out what's driving purchases. The design is templated, the copy is generic, and the "strategy" is basically sending a 20% off email whenever revenue dips.
If you're a brand doing under $1M in revenue and just need the basics built out, this tier is fine for that. But if you're at $3M+ and paying $2,000-$4,000/month for email, you're definitely leaving money behind.
$5,000 to $8,000/Month
This is where most $5M to $15M ecommerce brands end up, and it's where things start to actually feel like you have a real team working for you. At this level, a good agency is delivering:
- Full flow architecture (8-12 automated flows, not just welcome + abandoned cart + post-purchase)
- 4-5 campaigns per week with custom design
- SMS program management
- Segmentation that goes beyond "engaged vs. unengaged"
- A/B testing with documented learnings
- Bi-weekly strategy calls with a dedicated strategist
- Real newsletters that build brand affinity, not just promo after promo
The agency should feel like an extension of your team at this tier. They should be bringing ideas to you, finding opportunities in your data, and constantly evolving the program. Not just sitting around waiting for you to tell them what to do.
$8,000 to $15,000+/Month
Enterprise-level retention management for brands doing $15M+. At this level you're getting:
- Full lifecycle strategy across email, SMS, and push
- Cross-channel orchestration
- Advanced analytics and attribution consulting
- CDP integration and data architecture
- Weekly strategy calls with a senior team
- Custom creative production
- Dedicated account team - strategist, designer, and copywriter
At this price, the agency isn't just "doing your email." They're a strategic partner managing the entire retention side of the business, working with your paid media and creative teams to make the whole thing work together.
What the ROI Looks Like
The real question: will hiring an agency actually be profitable?
A good email and SMS agency should return 3x to 10x their fee. That's the range we see across our clients. The variance depends mostly on where you're starting from - a brand that's never had a real email strategy just has more low-hanging fruit to grab than one that's been optimized for two years already.
So if you're paying $8,000/month, you should be looking at $24,000 to $80,000 in incremental monthly revenue from email and SMS within about 90 days. Incremental being the key word - that's revenue you wouldn't have gotten without the agency's work.
One thing to be realistic about though: month one is never pretty. First month is all onboarding - learning the brand, getting aligned on preferences, building out flow architecture, establishing processes. The impact really starts compounding in months two and three. By month four, a good agency should be clearly in the green.
Industry data lines up with this too. EmailMonday puts the average email marketing ROI for ecommerce at 4,500%, or $45 for every $1 spent. Litmus says $36 returned per $1 invested across industries. Nearly 1 in 5 companies report email ROI above 7,000%.
The channel works. The difference is the strategy behind it.
When Hiring an Agency Doesn't Make Sense
We turn brands away. Not every business needs a recurring email agency, and honestly, any agency that takes on every single client regardless of fit is just optimizing for their own revenue.
Under $1M/Year in Revenue
If you're below a million a year, you usually don't have enough list size or website traffic for an agency to drive meaningful impact on an ongoing basis. The email list is too small and the acquisition volume is too low for advanced segmentation and lifecycle strategy to really move the needle.
What makes way more sense: hire an agency or a freelancer for a 2-3 month project to build your core automated flows. Welcome series, abandoned cart, post-purchase, browse abandonment, winback. Get the basics locked in so your acquisition spend works harder, then come back for ongoing management once you've actually scaled.
You Won't Give the Agency Room to Run
If you're going to micromanage every email, rewrite every subject line, and approval-gate every single campaign, you're basically paying agency prices for in-house execution. The whole point is leveraging their expertise. If you don't trust them to make decisions, you'll burn through the budget and end up disappointed no matter how good the agency is.
You Already Have a Strong In-House Team
Rare, but it happens. If you already have a dedicated email marketing manager, a designer who gets email, and a copywriter who can nail your brand voice, you might not need an agency. In our experience though, in-house teams are almost always worse. They're limited by bandwidth, they don't see the cross-brand data that agencies see from working with dozens of accounts, and they just can't match the testing velocity.
The Full Cost Picture
The agency retainer is one line item. Here's what the whole email and SMS program actually costs when you add it all up:
Klaviyo Platform Fees
Klaviyo charges based on your active profile count. Every contactable profile counts toward your tier whether you emailed them this month or not. Here's what that looks like in 2026:
| Active Profiles | Klaviyo Email Plan (Monthly) |
|---|---|
| Up to 5,000 | $100 |
| 10,000 | $150 |
| 25,000 | $400 |
| 50,000 | $720 |
| 100,000 | $1,380 |
| 150,000 | $1,955 |
| 250,000 | $2,300 |
These are email-only prices. SMS adds more on top. But in the grand scheme of things, Klaviyo is not expensive for what it does. A $50M DTC brand paying $2,000/month for arguably the most sophisticated email marketing platform on the market? That's a rounding error.
SMS Costs
If your agency is running SMS (and they should be), you're paying per-message on top of your Klaviyo plan. SMS credits run about $0.01 to $0.02+ per message depending on carrier and region. MMS with images costs more. For a brand sending around 50,000 SMS messages per month, budget another $500 to $1,000.
Creative Production
Most good agencies include design in their retainer. If yours doesn't, or if you need additional creative like custom photography or video, that's extra. Initial template buildout usually runs $2,000 to $5,000 as a one-time cost.
In-House Labor
This is the cost that people consistently underestimate. If you decide to do email in-house instead of hiring an agency, you're still paying for it. Just differently.
An email marketing manager in the US averages $89,000 to $107,000 in base salary (Robert Half, 2026). Then you add health insurance, PTO, 401(k) match, payroll taxes, equipment, software. All in, one person runs $120,000 to $150,000 per year.
And then there's your time. Somebody has to manage that person. Reviewing work, setting strategic direction, sitting in weekly meetings, giving brand feedback. That's hours every week that you could be spending on growth instead.
Plus, one person can't realistically cover strategy, copywriting, design, development, analytics, and deliverability management. So maybe you hire a designer ($65,000+). A copywriter ($60,000+). Now you're at $245,000+ per year for a team, and that's before your management time - and they still don't have the cross-brand pattern recognition that a specialized agency brings from working across dozens of accounts.
Or you hire an agency for $60,000 to $120,000 per year and get a full team with built-in stability. If someone on the agency team leaves, that's the agency's problem. If your in-house email marketer quits, you're scrambling for months.
Total Cost Comparison: Agency vs. In-House
Here's what the full annual investment looks like for a $10M ecommerce brand:
Agency route:
| Line Item | Annual Cost |
|---|---|
| Klaviyo platform (Email + SMS, ~50K profiles) | $10,000 - $14,000 |
| Agency retainer ($5K-$8K/mo) | $60,000 - $96,000 |
| SMS message costs | $6,000 - $12,000 |
| One-time template buildout | $2,000 - $5,000 |
| Total Year 1 | $78,000 - $127,000 |
| Total Ongoing (Year 2+) | $76,000 - $122,000 |
In-house route:
| Line Item | Annual Cost |
|---|---|
| Email Marketing Manager (salary + benefits + overhead) | $120,000 - $150,000 |
| Email Designer (part-time or shared) | $40,000 - $65,000 |
| Klaviyo platform | $10,000 - $14,000 |
| SMS costs | $6,000 - $12,000 |
| Training, tools, overhead | $5,000 - $10,000 |
| Your management time (est. 5-8 hrs/week) | Hard to quantify, but real |
| Total In-House (excl. management time) | $181,000 - $251,000 |
The agency route costs roughly half as much while giving you a broader skill set, cross-brand intelligence, and staffing stability. And the in-house number doesn't even factor in the time you personally spend managing the team.
Red Flags to Look For
After running an agency and watching what the rest of the market does, there are two big ones that stand out:
1. Long-Term Contracts With No Performance Clauses
If an agency wants you in a 12-month contract, ask yourself why they need that. A good agency keeps clients because the results keep them. Month-to-month or quarterly with a 30-day notice period is totally reasonable. If they need a legal agreement to keep you around, that says something about how confident they are in their own work.
2. Pricing That Seems Way Too Low
Sounds backwards, but it's probably the biggest one. If an agency is just competing on price ("We'll do your email for $1,500/month!"), you're getting a program that runs promos and discounts, claims big revenue numbers through attribution, and doesn't actually move your business forward.
These agencies survive on volume. They stack up as many clients as possible, template everything, and justify their existence by pointing at Klaviyo's built-in revenue attribution numbers. "Look, we drove $200K in email revenue this month!" Meanwhile, a huge chunk of that was from people who would have bought anyway and just happened to click an email link. We wrote about this attribution problem in our guide to how much revenue should actually come from email marketing. It's the same discount death spiral that's hurting so many ecommerce brands.
A $2,000/month agency managing a $10M brand is spreading their strategist across 15-20 accounts. You're getting maybe 2-3 hours of brain power per week, and most of that is execution, not strategy.
A Few Others Worth Noting
- Per-email pricing: Creates an incentive to send fewer emails instead of the right emails
- No dedicated strategist: If you're getting passed around to whoever's available that week, you'll never build momentum
- Revenue attribution as their main metric: Any agency that leads with Klaviyo-attributed revenue as their success metric is hiding behind a vanity number
- Design as the only differentiator: If the agency's whole thing is pretty templates, they're probably not doing real strategy underneath. Ask them about segmentation, list health, deliverability, DMARC, newsletter strategy. If they can't go deep on those topics, they're template-slingers.
Is the Agency Space Getting Commoditized?
At the template level, absolutely. There are hundreds of agencies and freelancers who will set up your welcome flow, abandoned cart, and a handful of campaigns for $2,000-$3,000/month. That work has been templated to death, and if that's all you need, you have plenty of options.
But real email and SMS strategy? That's having a bigger impact than ever.
Real bottom-funnel strategy is so much more than just sending emails. It's an entire creative and messaging framework designed to figure out why your acquisition spend isn't getting enough ROAS and actually fix it. It's making every customer come back. It's deepening the relationship between a brand and its customers so LTV compounds over time. It's understanding that the best way to lower your CAC isn't touching your ad accounts - it's making the back end of your funnel work way harder.
The market is flooded with agencies and freelancers masquerading as experts when all they're doing is running the same flows and templates for every client. Want to tell the difference? Ask an agency what makes them different. If the answer is mostly about design, you're probably looking at pretty templates without much strategic depth. If they're talking about segmentation, list health, deliverability, DMARC, newsletters, testing frameworks, and customer lifecycle modeling, you're in a different conversation entirely.
How to Evaluate a Klaviyo Agency
Before you sign anything, run through these:
- Ask about their process. What happens in month one? How do they learn your brand? What does their testing look like?
- Ask for case studies with real numbers. Not "we grew email revenue 300%." What was the incremental impact on total P&L? What did the brand look like before vs. after?
- Ask about deliverability. Do they monitor sender reputation? Do they know what DMARC is without having to look it up? Have they dealt with Apple MPP changes?
- Ask about team structure. Who's working on your account? How many other accounts are they managing? What's their experience level?
- Look at the contract terms. Month-to-month or quarterly with 30-day notice is reasonable. Anything over 6 months with no performance clause should give you pause.
- Look at their own content. Does their website show real expertise, or is it all generic "we help brands grow through email" type stuff?
- Trust your read on the sales process. If the first call feels like a pitch, be careful. If it feels like they're genuinely trying to understand your business and figure out whether it's a fit, that's a much better sign.
Frequently Asked Questions
How much does Klaviyo cost per month?
Klaviyo's email plan starts at $20/month for 500 contacts and goes up based on your active profile count. At 10,000 contacts you're looking at $150/month, 50,000 contacts is $720/month, and 100,000 contacts is around $1,380/month. SMS and extras cost additional. These are just platform fees and don't include agency management.
Is a Klaviyo agency worth it for small businesses?
If you're under $1M/year in revenue, a recurring retainer usually doesn't make sense. The list size and traffic just aren't high enough for advanced strategy to make a meaningful difference. Better to hire an agency for a 2-3 month project to build your core flows, then handle campaigns yourself until you're big enough for ongoing management.
What's the difference between a cheap and expensive email agency?
A $2,000-$4,000/month agency gives you templates, reactive service, and basic flow setup. A $5,000-$10,000+ agency gives you proactive strategy, custom segmentation, real testing, newsletters that build brand affinity, dedicated strategists, and custom design work. The more expensive agency treats email as a strategic revenue channel. The cheaper one treats it as a checkbox.
How long does it take to see ROI from a Klaviyo agency?
Month one is onboarding. Real impact starts in months two and three as flows go live and campaigns ramp up. By month four, a good agency should be delivering 3-10x their fee in incremental revenue. If you're not seeing clear ROI by then, something isn't working.
Should I hire in-house or go with an agency?
For most ecommerce brands, an agency is the more efficient path. One in-house email person runs $120,000-$150,000/year in salary, benefits, and overhead, and that one person can't cover strategy, copy, design, and analytics on their own. A good agency costs $60,000-$120,000/year and gives you a full team with cross-brand knowledge and staffing stability. Plus you skip the management overhead of running the team yourself.
What should I look for in a Klaviyo agency?
Strategic depth beyond just templates. Real case studies showing P&L impact. Knowledge of deliverability and list health. A dedicated team with clear roles. Flexible contract terms. A sales process that feels more like a consultation than a pitch. If an agency can't talk about segmentation, DMARC, and lifecycle strategy without stumbling, they're probably not the right fit.
