How Much Does an Email Marketing Agency Cost?

Short answer: most email marketing agencies charge between €500 and €8,000 per month on a retainer, depending on scope, your list size and sending volume, and how much strategy, copywriting and design they handle. Project-based work and revenue-share models exist too. Below is how each model works, what you actually get, and how to tell whether a price is fair.

The three pricing models you'll see

1. Monthly retainer (most common)

You pay a fixed monthly fee for an agreed scope: a set number of flows, a campaign calendar, copywriting, design, and reporting. Typical range is €500–€8,000/month. Lighter engagements (a few flows, a couple of campaigns a month) sit at the bottom; full-service retention programs for larger lists sit at the top. This model fits brands that want email handled end-to-end, every month.

2. Project-based / one-off

A fixed price for a specific deliverable, a flow build-out, a Klaviyo migration, or a retention audit. Expect roughly €2,000–€10,000 per project depending on complexity. Good when you need one thing done well rather than ongoing management.

3. Revenue share / performance

The agency takes a percentage of email-attributed revenue, usually 5–15%, sometimes on top of a smaller base fee. It aligns incentives, but watch the attribution model: make sure you agree on what counts as "email-attributed" before you sign.

What actually drives the price

• List size & sending volume, more subscribers and more sends mean more work and higher platform fees.
• Number of flows and campaigns, a welcome flow is one thing; a full lifecycle program with win-back, post-purchase, and VIP flows is another.
• Copywriting and design included?, agencies that write and design every email cost more than ones that just configure automations.
• Strategy depth, segmentation, send-time logic, and testing frameworks take expertise, not just a tool.
• Platform, Klaviyo, Mailchimp, Customer.io and Postscript all price differently, and that's usually billed on top of the agency fee.

What each price bracket typically buys

Ranges are only useful if you know what moves you from one end to the other. Roughly, this is what changes as the retainer goes up:

Monthly	Typical scope	Who it fits
€500 to €1,000	Core lifecycle flows built and maintained, a small number of campaigns, basic reporting	Stores getting retention off zero
€1,000 to €2,500	Full flow set, a planned campaign calendar, copy and design, segmentation, monthly testing	Stores where email is already a real revenue line
€2,500 and up	The above, plus deeper strategy, more creative volume, SMS, and dedicated account time	Larger lists, several products or markets

The jump between brackets is almost never "more emails." It is how much thinking, writing and designing happens before an email goes out, and how much someone looks at the numbers afterwards.

What is not in the agency fee

Agency quotes are often compared as if they cover everything. They do not, and the gaps are predictable:

• Your email platform. Klaviyo, Mailchimp or Customer.io bill you directly, and the cost scales with your list, so it grows as the program works.
• SMS. Usually a separate tool and separate per-message cost, even when the agency runs it.
• Photography and product assets. Most agencies design with what you already have. New shoots are their own line item.
• Discount margin. The cheapest way to make retention emails look successful is to give away margin. Ask how much of the attributed revenue came with a code attached.

None of this makes an agency expensive by stealth. It just means the retainer is not the total cost of the channel, and you want the full picture before comparing two proposals side by side.

How to tell whether the price is worth it

You do not need a model for this. Two numbers decide it.

The first is what an additional repeat purchase is worth to you: your average order value times your gross margin. The second is how many of those the program would need to produce each month to cover the retainer. Divide the second by the first and you have the honest break-even, in orders, not in percentages.

For most stores that number turns out to be small enough that the question is no longer "can we afford it" but "will this actually produce those orders." That is the right argument to be having, and it is the one a good agency will have with you before you sign. You can put your own numbers into the retention revenue calculator if you want the estimate in front of you first.

One caveat worth saying out loud: if your store is doing very little revenue yet, a full retainer is usually the wrong purchase. A focused audit or a single well-built post-purchase flow will teach you more per euro, and you can always scale up when the traffic justifies it.

What you should get for the money

Whatever the model, a good email marketing agency should deliver:

• A clear strategy tied to revenue, repeat-purchase rate, and retention, not just "more emails."
• Human-written copy and on-brand design, not autogenerated filler.
• Proper segmentation and send-time logic, so the right people get the right message at the right time.
• Transparent reporting you can actually read, and a named point of contact.

Red flags when comparing agencies

• Rigid "packages" that ignore your brand, list, and goals.
• AI-generated copy sold as strategy, or "AI-powered" badges with nothing behind them.
• No agreed KPIs, if no one defines success up front, you can't hold anyone to it.
• Long lock-in contracts with no performance guarantee.

How to compare two proposals fairly

Two quotes for "email marketing" can differ by a factor of four and both be honest. Before you read them as cheap and expensive, line them up on the same five points:

1. Output per month, in units. How many flows, how many campaigns, how many creative variants. "Ongoing optimisation" is not a unit.
2. Who writes and designs. A quote that includes copy and design is doing work the cheaper quote is quietly leaving with you.
3. Reporting. Which numbers, how often, and can you see them yourself in the platform.
4. Notice period. A month or two is normal. Twelve-month lock-ins with no performance clause are a bet you are making alone.
5. What you keep. The Klaviyo account, the flows, the templates and the copy should stay yours when the relationship ends. Ask explicitly, and ask for it in writing.

That last point catches people out more often than price does. If an agency builds everything in their own account, or hands back a set of images without editable files, leaving them costs you the entire program and you start again from zero. The cheaper retainer is not cheaper if it has a hostage clause in it.

Also worth asking: who does the work day to day. Some agencies sell the founder and staff the account with someone else entirely. That is not automatically bad, plenty of good work is done by teams, but you should know the answer before you sign rather than after the second month.

How real. approaches pricing

We don't do fixed packages. Engagements typically start from €500/month, and most brands invest €500–€2,000/month, scaled to your brand's size, scope, and the services you actually need (retention email flows, brand content, ad creatives). And we back the work with a 90-day guarantee: if you don't see measurable improvement in email-attributed revenue, repeat purchase rate, or support-ticket volume within 90 days, we keep working at no extra cost until you do.

Frequently asked questions

How much does an email marketing agency cost per month?

Most email marketing agencies charge between €500 and €8,000 per month on a retainer, depending on scope, list size, sending volume, and whether copywriting and design are included. Smaller, focused engagements can start lower; full-service retention programs run higher.

Is an email marketing agency worth it for a small Shopify brand?

For most Shopify brands doing €50k–€2M a year, yes. Email and retention are usually the highest-ROI channel, and a good agency pays for itself through repeat purchases. Below roughly €50k a year in revenue, a focused audit or a few core flows often makes more sense than a full retainer.

What is the difference between a retainer and a revenue-share pricing model?

A retainer is a fixed monthly fee for an agreed scope of work. Revenue share charges a percentage of email-attributed revenue, typically 5–15%, so cost scales with results. Many agencies use a hybrid: a smaller base fee plus a performance component.

Does real. have fixed email marketing packages?

No. We price each engagement to your brand's size, scope, and the services you need, and back the work with a 90-day guarantee. Book a free 30-minute call for a transparent proposal.
