How Much Does Email Marketing Cost?

Email is often called the cheapest marketing channel, and it can be. But “cheap” hides a lot of variation. A local shop emailing 400 customers once a month might pay nothing. An online store sending daily campaigns and automated flows to 50,000 subscribers might spend a meaningful monthly sum on software alone, before anyone writes a word.

The total depends on 3 things: the platform’s pricing model, the size of your list and how much of the work you hire out. This guide explains each so you can budget with confidence, and so a growing list doesn’t surprise you with a bigger bill.

The 4 parts of email marketing cost

Optional extras include SMS add-ons, a dedicated sending IP for high-volume senders, list-growth tools like pop-up builders, and integrations with your store or CRM.

How email platforms price their plans

Most platforms use one of 3 pricing models. Knowing which one you’re on is the key to predicting future costs.

Contact-based pricing

You pay based on how many contacts or subscribers you store, often in tiers. Mailchimp, Kit and Klaviyo all tie plan prices to list size. Kit, for example, prices its paid plans by subscriber count, and its own pricing page lists its Creator plan at $33 a month for 1,000 subscribers as of October 2026.

Watch out for: paying for contacts who never open. On contact-based plans, unengaged subscribers cost money every month. Some platforms also count unsubscribed or archived contacts differently, so check what counts toward your tier.

Send-based pricing

You pay for the number of emails you send per month, regardless of list size. Brevo is a well-known example: its pricing is based mainly on email volume rather than contact count.

Good for: businesses with large lists that email infrequently, such as a quarterly newsletter.

Tiered features

Almost every platform also splits features across plans. Free and entry plans handle basic newsletters. Higher plans add multi-step automation, A/B testing, advanced segmentation, more users and phone support. You may move up a plan for a feature, not just for list size.

Overages and introductory pricing

2 details often catch owners out:

• Overages. Mailchimp’s pricing page says overage charges apply if you exceed your plan’s contact or send limit, rather than simply stopping your campaigns on paid plans.
• Introductory discounts. Several platforms show discounted first-year or first-months pricing. Kit’s Pro plan, for example, shows a first-year discount before it renews at the standard rate. Always check the renewal price.

Key takeaway: Your email software bill grows with your list. Before you choose a platform, price it at your current list size and at 2 to 3 times that size, so you know what success will cost.

What free plans actually include

Free plans are a real option for small lists, but their limits vary widely. Here’s what a few major platforms published as of October 2026. Limits change, so confirm on each vendor’s pricing page.

Free plans usually limit automation, remove A/B testing or add platform branding to your emails. They’re a good way to start, but don’t build complex flows on a free plan if you’ll need to rebuild them later on another tool. Our guide on choosing an email marketing platform covers what to compare beyond price.

Design costs

You don’t need custom design to send effective emails. Most platforms include drag-and-drop templates you can brand with your logo, colors and fonts in an afternoon.

If you do hire help, it’s usually priced as:

• A one-off template project: a designer builds 1 to 3 reusable templates in your platform.
• Per-campaign design: paying for each email layout, common for retail brands with frequent promotions.
• Included in a retainer: agencies often bundle design into monthly management.

Rates vary widely by region, experience and scope, so get 2 or 3 quotes with the same brief. Ask whether templates will be built directly in your platform and whether you’ll own and be able to edit them.

Copywriting and strategy costs

Writing is where most of the time goes. Your options:

• Do it yourself. Costs time, not cash. A simple newsletter might take a couple of hours once you have a routine.
• Freelance copywriter. Usually priced per email, per automated flow or by the hour.
• Monthly retainer. A freelancer or agency plans and writes a set number of emails each month.

AI writing tools can speed up drafts, but you still need to edit for accuracy, voice and offers. Our first-month email marketing plan shows how to set up a sustainable routine before paying anyone.

Agency costs

Agencies typically charge a monthly retainer to manage strategy, design, writing, automation and reporting. Some ecommerce-focused agencies add a performance component tied to email-attributed revenue.

An agency makes sense when:

• Email drives a large share of your revenue and you’re leaving money on the table.
• You need complex automation and segmentation built properly.
• Nobody in-house has the time or skills.

It usually doesn’t make sense when your list is small or you send a simple monthly newsletter. Start with software and in-house writing, prove the channel works, then hire help.

Hidden and extra costs to budget for

• SMS add-ons. Many email platforms sell text messaging separately, usually per message or with credits. SMS also comes with strict consent rules; see our SMS marketing guide.
• List growth tools. Pop-ups, quizzes and landing pages may be included or cost extra. Our guide to building an email list covers the free options.
• Integrations. Connecting your store, booking system or CRM may require a higher plan.
• Extra users. Some plans limit how many team members can log in.
• Dedicated IP. Only relevant for very high-volume senders. Smaller senders usually do better on a shared IP managed by the platform.
• Your time. The biggest real cost for most small businesses.

Domain authentication (SPF, DKIM and DMARC) doesn’t usually cost anything extra and matters for reaching the inbox. See our email deliverability guide.

How to build your email marketing budget

1. Count your real list. Only contacts who opted in and have engaged in the past year or so.
2. Decide how often you’ll send. This determines whether contact-based or send-based pricing suits you.
3. List the features you need now. Usually automation, segmentation and a store or CRM integration. Our guide to marketing automation explains which automations to start with.
4. Price 2 or 3 platforms at your current size and at 2 to 3 times that size.
5. Decide what you’ll do in-house. Writing and basic design are realistic for most owners.
6. Add outside help only for specific gaps, such as a one-off template build or setting up automated flows.
7. Review quarterly. Remove unengaged contacts and check whether you’re paying for features you don’t use.

Is email marketing worth the cost?

Email has 2 big advantages: you own the list, and automated flows keep working after you build them. Rather than relying on industry averages, measure your own return. Track revenue, bookings or leads from email against the software and labor you spend. Our guide to measuring marketing ROI shows how.

Conclusion

Email marketing cost comes down to your platform’s pricing model, your list size and how much work you outsource. Start on a free or entry plan, keep your list clean so you’re not paying for silent contacts, check renewal and overage terms, and add design or agency help only where it clearly earns its keep.
