How much does email marketing cost per month for a small Shopify store?

A small store can start close to free. Shopify Email gives you 10,000 sends a month at no cost, and Klaviyo and Omnisend both have free plans up to 250 contacts. Once you outgrow the free tiers, expect roughly $20 to $30 per month on Klaviyo at 500 to 1,000 profiles. The bigger cost is production, so if you write the emails yourself your cash cost stays low.

Why is Klaviyo more expensive than it looks?

Since February 2025 Klaviyo bills on active profiles, meaning every contact you could email counts toward your price whether you send to them or not. A list padded with inactive subscribers pushes you into a higher tier. Cleaning your list is one of the few moves that directly lowers your bill.

Is it cheaper to use an agency or do email marketing in-house?

In-house is cheaper in cash and an agency is cheaper in time. An agency retainer of $1,500 to $5,000 a month buys you a team that plans and produces campaigns for you. In-house keeps that money but spends your hours. AI generation tools sit in the middle: a flat monthly fee instead of a retainer, with you still in control of what goes out.

Is email marketing worth the cost for an online store?

For retail and ecommerce, email returns about $45 for every $1 spent, which is why it stays the highest-margin channel most stores have. The spend only pays off if campaigns actually ship, so the deciding factor is rarely the app fee. It is whether you can produce good emails consistently without burning your week.

Email Marketing Cost for Shopify Stores: The Real 2026 Numbers

Email marketing cost for a Shopify store breaks into two buckets, and most pricing guides only show you one. The first is the app you send from, which ranges from free on Shopify Email up to about $30 to $150 per month on Klaviyo once your list grows. The second is production: the money or hours it takes to actually write, design, and schedule the campaigns every week. That second bucket is where most of the real spending hides, and it is the part that decides whether email is cheap or expensive for you.

How much does email marketing cost for a Shopify store?

Add the two buckets and a typical Shopify store lands somewhere between almost nothing and a few thousand dollars a month. The spread is that wide because the app is the small, fixed part and production is the large, variable part.

Here is the honest shape of it:

App or ESP fee: $0 to roughly $150 per month for most stores under 10,000 subscribers.
Production: $0 if you do it yourself in time you already have, $500 to $2,000 per month for a freelancer, or $1,500 to $5,000 per month for an agency.
Occasional extras: list cleaning, a paid template, an image tool. Small, and easy to skip early on.

A store owner writing their own two campaigns a week on Shopify Email can run real email marketing for close to $0 in cash. A store paying an agency to run a full program on Klaviyo can spend $3,000 or more. Same channel, very different bill, and the difference is almost never the software.

What do the email apps actually cost in 2026?

These are the three senders a Shopify store realistically picks between, with prices verified at the time of writing. Every one has a free tier, so you can start without paying anything.

Shopify Email (native):

10,000 free email sends every month on Basic, Grow, Advanced, and Plus plans.
After that, $1 per 1,000 emails, dropping to $0.65 and then $0.55 per 1,000 at high volume.
No monthly platform fee. You pay only for sends past the free block, and it lives inside your Shopify admin.

Omnisend:

Free plan: 250 contacts and 500 emails per month.
Standard plan from $11.20 per month for up to 500 contacts, scaling as your list grows.
Built for ecommerce, with popups and automations included.

Klaviyo:

Free plan: 250 active profiles and 500 sends per month.
Email plan by list size: about $20 at 500 profiles, $30 at 1,000, $45 at 1,500, $100 at 5,000, and $150 at 10,000.
One thing to watch: since February 2025 Klaviyo bills on active profiles, so every contact you could email counts, sent to or not.

That Klaviyo detail matters more than it sounds. A list bloated with people who never open pushes you up a tier and raises your bill without adding a dollar of revenue. Pruning dead subscribers is one of the few actions that lowers the app cost directly.

Why the app fee is the cheap part

Look back at those numbers. Even at 10,000 subscribers, the software runs $150 per month or less. Now price the work of filling that software with good emails, week after week.

A single well-built campaign email, briefed, written, designed, and QA'd, is a couple of hours of skilled work. Run three or four a month plus your automations and you are looking at real labor. That is why the production line, not the platform line, is where store budgets actually get spent:

Do it yourself: $0 in cash, but several hours every week that come out of everything else you run.
Freelancer: commonly $15 to $150 per hour, or a $500 to $2,000 monthly retainer for a set number of campaigns.
Agency: typically $1,500 to $5,000 per month for a small-to-mid store, and higher as scope grows.
AI generation: a flat monthly tool fee that produces on-brand drafts from your store data, with you reviewing and approving.

The mistake in most cost guides is treating email marketing as a software purchase. For a lean Shopify team it is a production problem. The tool is settled in an afternoon; the question that repeats every week is who is writing Friday's campaign.

What does an email marketing agency cost, and when is it worth it?

Agency pricing clusters into a few models. Retainers run $1,500 to $3,000 per month for a small store and $3,000 to $10,000 or more for a larger one. Some charge per project, around $250 to $1,000 for a single email and $1,000 to $5,000 to build out a multi-email automation. A few use a hybrid: a base fee plus a percentage of the revenue they drive.

An agency earns its retainer when your list is large enough that a few points of improvement outweighs the fee, or when you genuinely have no hours to give email. It stops making sense when your store is small, your margins are tight, or you find yourself rewriting the agency's drafts to sound like your brand anyway. Plenty of stores hire an agency, learn the cadence, then bring it back in-house once the system is running.

What does a real monthly email budget look like?

Two example stores, built only from the verified numbers above.

Store A: just getting serious, ~1,000 subscribers, owner writes the emails
  App        Shopify Email (under 10k sends)     $0
             or Klaviyo at 1,000 profiles        $30
  Production owner's time (2 campaigns/week)      $0 cash
  --------------------------------------------------
  Cash cost                                       $0 to $30 / month

Store B: growing, ~10,000 subscribers, wants help producing campaigns
  App        Klaviyo at 10,000 profiles           $150
  Production freelancer                            +$500 to $2,000
             or agency                             +$1,500 to $5,000
             or AI generation (flat tool fee)      + one predictable fee
  --------------------------------------------------
  Total                                            $150 app + production

The pattern holds at every size: the app is a rounding error next to production. So the cheapest real lever is not switching ESPs to save $20. It is lowering the cost of producing campaigns without lowering their quality.

How do you keep email marketing costs down without gutting results?

A few moves actually move the number:

Start on the free tier and stay there until you outgrow it. Shopify Email's 10,000 free sends cover a lot of early stores.
Clean your list. On profile-based billing like Klaviyo's, removing unengaged contacts lowers your tier and lifts your open rates at the same time.
Keep production in-house but make it fast. The reason stores hire out is the blank page, not the sending. Tools that draft on-brand campaigns from your real products and branding cut the slow part while keeping the money and control with you.
Batch your planning. Deciding a month of campaigns in one sitting is far cheaper in hours than reinventing each send the day it goes out.

This is the seam JetFlow is built for. It reads your store's actual products, branding, and data, then generates campaign emails and popups you review and push to Klaviyo, so a one-person team can produce a full month of on-brand campaigns without an agency retainer or a lost week. It does not replace your sender or pretend the app fee is the problem. It attacks the production cost, which is the part that actually adds up.

Is email marketing worth the cost?

For retail and ecommerce, email returns roughly $45 for every $1 spent, the highest of any channel most stores run. That return is the reason the cost conversation is worth having at all. But the ROI only shows up if the emails ship. A $150 Klaviyo bill with three campaigns a month earns nothing extra over a $150 bill with twelve. The spend pays off when production is cheap and consistent enough that your calendar stays full, which loops right back to the real cost of email marketing. It was never the software. It was the work.

For the sending side of that work, a good place to start is writing campaigns people open. See our guide to abandoned cart email subject lines for copy you can use this week.
