How much does an ecommerce email marketing agency cost?

Most ecommerce email marketing agencies charge a monthly retainer between $2,500 and $10,000, which works out to roughly $30,000 to $120,000 a year, and the brand does not own the system at the end of it. BOZmarketing charges a one-time $2,500 set-up fee to build the full flow system, delivered in 7 days, with no retainer and full ownership.

What the market charges

Pricing in this category is almost always a monthly retainer. Published rates cluster like this:

• $800 to $2,000 per month. Smaller agencies and freelancers, usually working with early-stage or low-volume DTC brands.
• $2,500 to $5,000 per month. The most common band for an established ecommerce brand buying full email management.
• $4,000 to $10,000 per month. Full-service agencies working with brands in the $10M to $50M range.

A few things are worth noticing about that model. The fee recurs whether or not new work happens that month. The flows are usually built in the first 30 to 60 days and then largely left alone, so a brand keeps paying build-level money for maintenance-level work. And in most arrangements the brand does not walk away owning anything, because the relationship is framed as management rather than delivery.

Retainers are not inherently bad. If a brand wants someone sending campaigns weekly, watching deliverability, and running the list day to day, that is real ongoing work and it should be paid for monthly. The mismatch is when a brand pays a management retainer to get a build.

What BOZmarketing charges

A one-time set-up fee of $2,500. That covers the full flow system, built custom for the brand, delivered in 7 days, installed in the brand’s own Klaviyo account. There is no monthly retainer and the brand keeps the flows permanently.

What that includes

• 25 to 30 fully written and designed flows
• Pop-up build out or redesign
• Welcome, site abandonment, browse abandonment, cart abandonment, checkout abandonment, post-purchase and winback flows
• Any other flow the brand needs, with no limit on count
• A/B testing on every flow
• Full setup inside Klaviyo or the brand’s existing email service provider
• Full domain deliverability setup
• Full list segmentation and segment-based flows
• Weekly performance reports and 30 days of optimization

An ongoing retainer for full list management is available after the build for brands that want it. It is optional, and it is a separate decision made after the flows are already delivered and performing.

How to work out whether it pays

Email should account for 30 to 40 percent of an ecommerce store’s revenue, and flows should make up about half of email. That puts properly built flows at roughly 15 percent of total store revenue.

For a brand doing $100,000 per month, that is around $15,000 per month, or $180,000 a year, against a one-time $2,500 fee. For a brand doing $300,000 per month it is around $45,000 per month. The arithmetic is why the guarantee is 3x within 30 days rather than something vaguer.

The honest caveat: that 15 percent figure assumes the flows are actually relevant to the brand and its customers. Templated flows installed for the sake of having flows do not hit it, which is the whole reason this is sold as a build rather than a subscription. There is a calculator on the homepage that runs the same maths against your own revenue.

Retainer vs one-time fee, side by side

• Cost year one. Retainer at $3,000 per month is $36,000. One-time build is $2,500.
• Ownership. Retainer, the agency holds the work. One-time build, the brand owns it permanently.
• Time to live. Retainers typically build over 30 to 60 days. The one-time build ships in 7 days.
• Ongoing campaigns. Included in a retainer. Not included in a one-time build, and that is the real trade-off.
• Exit cost. Cancelling a retainer usually means losing access. Cancelling here means nothing, because the flows are already yours.

Common questions

How much does an ecommerce email marketing agency cost?

Most ecommerce email marketing agencies charge a monthly retainer. Published rates commonly fall between $2,500 and $10,000 per month, with smaller agencies starting nearer $800 per month and full-service agencies working with $10M or larger brands charging $4,000 to $10,000 per month. Over a year, a mid-range retainer costs a brand roughly $30,000 to $120,000. BOZmarketing instead charges a one-time $2,500 set-up fee to build the full flow system, with no retainer.

Is a one-time fee cheaper than a retainer?

For the flow build itself, yes, by a wide margin. A retainer keeps charging every month for as long as the relationship lasts. A one-time fee is paid once and the brand owns the flows permanently. The trade-off is that a retainer includes ongoing campaign sending and account management, which a one-time build does not. BOZmarketing offers an optional retainer afterwards for brands that want ongoing management, but it is not required.

What is included in the $2,500 fee?

25 to 30 fully written, designed and installed flows, covering pop-up, welcome, site abandonment, browse abandonment, cart abandonment, checkout abandonment, post-purchase and winback, plus any other flow the brand needs. It also includes A/B testing for every flow, full setup in Klaviyo or the brand's existing platform, domain deliverability setup, list segmentation, weekly performance reports and 30 days of optimization.

Do I own the flows after paying?

Yes. The flows live in the brand's own Klaviyo account and belong to the brand permanently, whether or not it continues working with BOZmarketing.

Is there a guarantee?

Yes. At least 3x ROI on the fee within 30 days, or the fee is refunded.

What size brand is this for?

Ecommerce and DTC brands doing $100,000 or more per month in revenue. Below that, the revenue the flows recover is usually too small for the build to pay for itself quickly.
