Ask "how much does email marketing cost?" and you will get answers ranging from "it's free" to a monthly agency retainer. Both can be true, because the software is often the smallest part of the bill.
Your own hours are the cost owners often leave out, so this guide counts them next to the platform fees and the price of hiring a freelancer or an agency.
How much does email marketing cost? Four things you pay for
Whoever does the work, the bill breaks down the same way:
- The platform: a monthly subscription, priced either by how many contacts you store or by how many emails you send.
- Design and setup: a template that matches your branding, the sign-up forms, and the automations behind them. This is mostly a one-time cost.
- Building and keeping the list: lead magnets, forms, and the occasional list cleaning.
- Someone's time every month: planning, writing, building, proofing, scheduling, and reading the results afterward.
In our experience the fourth part is the biggest cost for most small businesses, and if you do the work yourself it never shows up on an invoice. If you are still deciding whether to run email at all, start with our guide to email marketing for small business and come back to the money afterward.
What email platforms charge
Platforms charge in one of two ways. Pricing per contact stored suits a small list you email often, and pricing per email sent suits a large list you email rarely. This is what three vendors publish on their own pricing pages, as checked on September 25, 2026:
| Platform | Free tier | Paid plans start at | Billed by |
|---|---|---|---|
| MailerLite | Up to 250 subscribers, 2,500 monthly emails | $12/month (Comfort), $25/month (Power) | Subscribers |
| Mailchimp | Limit of 250 contacts | $13/month (Essentials) and $20/month (Standard) for the first 12 months at the smallest contact tier | Contacts |
| Brevo | Up to 300 emails per day | Published on the pricing page by send volume | Emails sent |
Watch for two things. Introductory rates run for a fixed period (Mailchimp's covers the first 12 months), and the price steps up after that. Per-contact plans also charge for inactive contacts still sitting in the account, so cleaning the list keeps the bill down as well as helping deliverability.
Design and setup
Most platforms ship templates that look fine once your logo and colors are dropped in, so you can start with no design spend. Paying for design gets you a template that matches the rest of your brand, renders correctly in Outlook and on phones, and does not have to be rebuilt for every send.
Setup is the bigger piece of work: sign-up forms on the site, the connection to your booking or invoicing system, domain authentication so your messages reach the inbox, and the first automated sequences. You pay for it once, and it takes away the fiddling you would otherwise repeat every month. Our email setup puts your newsletter on the right platform with your branding, then writes, designs and automates your first sequences.
What it costs to build and keep a list
List building is usually one of the cheapest lines in the budget, because the best sources are free: the customers already in your invoicing system, a form on the site, a line in your email signature. We go through all of them in how to build an email list from the customers you already have.
The costs that do appear are a lead magnet worth signing up for (an afternoon of writing, or a small design fee) and list verification if you are importing an old file. Most verification services charge per address checked. Do not buy a list. It usually costs you more than it returns once you count the complaints and the damage to your deliverability.
The costs nobody budgets for
- Deliverability work: setting up SPF, DKIM and DMARC, and fixing it when messages start landing in spam.
- Integrations: getting your booking, CRM or invoicing system to talk to the email platform, which sometimes means an add-on subscription.
- Replies: a good campaign generates questions, and somebody has to answer them the same day.
- Overage charges: per-contact plans bill by tier, so crossing a threshold moves you up a band mid-year.
- The rebuild: a program set up by someone who has since left usually needs untangling first.
Doing it yourself, a freelancer, or an agency
Count your own hours when you compare the options. One decent monthly email (planned, written, built, proofed, scheduled and reviewed) takes a few hours of concentrated work from someone who knows the business. For an owner, those are hours that could have gone into quoting jobs, and that lost time is the price of doing it yourself.
- Do it yourself: you pay for the platform and your time. It makes sense while the list is small, and it is a good way to learn what your customers respond to.
- A freelancer: usually paid per email or per month for writing and building, and usually without strategy, deliverability or reporting attached.
- An agency: a monthly retainer covering strategy, writing, design, automation, list health and reporting. It is worth it when email is a real revenue channel rather than an occasional newsletter.
What a retainer buys, and how agencies price it
Agency pricing for email generally takes one of three shapes: a flat monthly retainer for an agreed number of campaigns and automations; a project fee for setup followed by a smaller ongoing fee; or an hourly rate, which is usually the least predictable for both sides.
Whatever the shape, ask what is included: how many campaigns a month, who writes them, whether automations and list cleaning are in scope, and whether the platform account is in your own name. Our email marketing service covers newsletter setup, automated sequences, list maintenance, and tracking of opens, clicks and revenue; the quote depends on how many campaigns you send and how much of the writing you want to keep in-house.
Working out what you get back
Published return-on-investment multiples are averages across many other businesses, and their economics can be very different from yours. Leave them aside and do the arithmetic with your own numbers:
- Take the total monthly cost: platform, plus fees, plus your own hours at what an hour of your time is worth.
- Count the jobs that came from email in the same month. Ask on the booking form, or use a link that only appears in your emails.
- Multiply by your average job value, then by the share of that which is margin rather than revenue.
Run that for three months before you judge the channel. A single campaign tells you almost nothing, while a quarter's worth of campaigns tells you whether the list is worth the money.
Common questions
How much does an email marketing campaign cost?
On a plan billed by contacts, the marginal cost of one more campaign is close to zero, since you are already paying to store those contacts. On a plan billed by emails sent, each campaign uses up part of your send allowance. Either way, most of what you pay for is the few hours that go into writing and building it, which is why a per-campaign quote is mostly labor.
Can a small business do email marketing for free?
Up to a point, yes. MailerLite publishes a free plan for up to 250 subscribers and 2,500 monthly emails, and Mailchimp's free plan is capped at 250 contacts, so a business with a small list can run a newsletter without a subscription. You pay in time instead, and a growing list soon outgrows the free tier.
Is email marketing cheaper than Google Ads?
Per message, by a wide margin, because you are not bidding for anything. The two do different jobs, though: ads reach people who have never heard of you, and email reaches people who already have. Many small businesses need both, and our guide to how much Google Ads cost covers the ads side of that budget.
What to do next
Price the four parts: pick a platform tier that matches your contact count, decide whether setup is a one-time job you pay for or a weekend you spend, and put a real number on the monthly hours. Add those up and you have your cost, of which the subscription is only one line. If the answer changes your mind about the channel, re-read the small-business email marketing guide before you drop it.
If you would like that priced properly for your list and your sending schedule, tell us how many customers you have and how often you want to email them, and we will come back with a scope and a number.
