Most Shopify ads and email agencies charge between $2,000 and $10,000 per month in 2026. Bigger ad accounts often add a percentage of spend on top, usually 10% to 20%.

I ran a clothing brand for 15 years and spent over $5 million of my own money on Facebook ads. I've been the client on both sides of these contracts. Here's the real breakdown.
1. Flat Monthly Retainer
A flat retainer is the most common model, running $2,000 to $10,000 per month for most Shopify brands. You pay a fixed fee no matter how much you spend on ads, which makes budgeting simple. The risk is that a lazy agency collects the same check whether they hustle or coast.
2. Percentage of Ad Spend
Here the agency takes a cut of your media budget, typically 10% to 20% per WebFX pricing data. Spend $50,000 a month and a 15% fee costs you $7,500. This works for high-spend accounts but gets ugly fast, because the agency earns more when you spend more, not when you profit more.
3. Performance or Revenue Share
Performance pricing ties the fee to results, often 5% to 15% of the revenue the agency drives. It sounds fair, and clients love it because the agency only wins when you win. The catch is attribution. Agencies fight over which sales count as theirs, and the tracking games get old quick.
4. Project or Sprint Pricing
Some work is one-and-done, like a store rebuild, a creative package, or a Klaviyo migration. Project fees usually land between $3,000 and $25,000 depending on scope. This is the cheapest way to test an agency before you sign a long retainer.
5. Email and Retention Retainers
Email and SMS agencies price separately from ads, usually $1,500 to $6,000 per month for Klaviyo flows, campaigns, and list growth. Good email should drive 25% to 40% of a store's revenue, per Klaviyo benchmark reports. If your email is under 20% of revenue, that retainer pays for itself fast.
6. Hybrid Retainer Plus Percentage
The most common setup for growing brands is a base retainer plus a percentage of spend. You might see $3,000 per month plus 10% of ad spend over a threshold. It caps the agency's downside and rewards them for scaling, but always ask where the percentage kicks in so it doesn't quietly eat your margin.
7. AEO and Agentic Commerce Setup Fees
Getting a Shopify store ready for AI shopping is new work, and pricing is still forming. Setup projects run roughly $2,500 to $15,000, with a smaller monthly fee to keep product data and content cited by tools like ChatGPT and Perplexity. This is where the next wave of buying is going, and very few agencies price for it yet.
8. Enterprise and Full-Funnel Contracts
Brands doing $10 million or more usually sign full-funnel contracts covering ads, email, creative, and strategy. These run $10,000 to $50,000 per month, sometimes with a revenue-share layer on top. At this tier you're paying for a team, not a freelancer with a nice deck.
What Actually Drives the Price
Three things move the number: your ad spend, the number of channels, and how much creative they produce. A brand spending $200,000 a month needs more hands than one spending $20,000, so the fee climbs. Named benchmarks from Clutch agency listings line up with these ranges across thousands of real projects.
How to Avoid Overpaying
Don't pay a percentage of spend on a low-margin account. The math kills you before the ads ever profit. Ask for a project or a 90-day trial before a long retainer, and make every agency show you real client numbers, not case study screenshots. Data does not lie.
How We Chose These Ranges
These ranges come from public agency pricing pages, Clutch and WebFX benchmark data, and my own years signing and firing agencies as a Shopify brand owner. We don't publish WRKNG's specific pricing here, because the right number depends on your spend and margin.
FAQ
How much does a Shopify ads agency cost per month in 2026?
Most Shopify ads agencies charge $2,000 to $10,000 per month, and high-spend accounts often add 10% to 20% of ad spend on top. Enterprise brands pay $10,000 to $50,000 per month for full-funnel work.
Is percentage of ad spend or a flat retainer better?
A flat retainer is safer for lower-spend or lower-margin brands because your fee stays predictable. Percentage of spend only makes sense once your account is large and clearly profitable.
How much do Shopify email marketing agencies charge?
Email and SMS retainers usually run $1,500 to $6,000 per month for Klaviyo flows, campaigns, and list growth. Strong email should return 25% to 40% of your total store revenue.
What is a fair agency fee for a small Shopify store?
For a store spending under $20,000 a month, a flat retainer of $2,000 to $4,000 or a fixed project fee is usually fair. Avoid percentage-of-spend deals until your margins can carry them.
How do I avoid overpaying an agency?
Start with a project or a 90-day trial instead of a long contract, and make the agency show you real client revenue numbers. Never sign a percentage-of-spend deal on a thin-margin account.
