Email Marketing Cost Calculator (2026)
Email marketing pricing is confusing on purpose — every tool uses a different model, and the headline price rarely matches what you'll actually pay. Move the sliders to your list size and sending habits, and we'll estimate your monthly cost across the major platforms so you can compare apples to apples.
That's about 10,000 emails sent per month.
Estimated range: — per month. Lower is not always better — see below.
Constant Contact is rarely the cheapest line on this calculator — and we'll never pretend otherwise. We still recommend it for most non-technical small businesses and nonprofits because of what the price buys: live phone support, genuinely easy setup, and built-in event tools. If your priority is the lowest possible bill, Brevo or MailerLite usually win; if it's a tool you can actually run without a marketer, this is our pick.

Almost every email tool charges one of two ways, and the difference is the single biggest factor in your bill:
Per-contact pricing
Constant Contact, Mailchimp, MailerLite, and GetResponse charge by how many contacts you store, in tiers. The cost is the same whether you email that list once a month or every day — but it climbs every time your list grows past a tier. This model is simple to predict and fine for steady senders, but it punishes you for having a big list you rarely email.
Per-email pricing
Brevo charges by emails sent, not contacts stored — you can hold a huge list for free and only pay when you actually send. For an organization that emails a large list occasionally (think a membership body or a seasonal campaign), this can be dramatically cheaper. The trade-off: if you send to your whole list very frequently, those send counts add up.
How to use this calculator
Set the first slider to your number of subscribers and the second to how many times a month you email your list. The "emails sent per month" figure (contacts × campaigns) is what drives a per-email tool like Brevo. The results re-sort instantly from cheapest to most expensive, each tagged with its pricing model so you can see why one is cheaper than another at your size.
Why the cheapest tool isn't always the best value
Price is only one input. A tool that costs $10 less a month but takes you twice as long to use, or leaves you stuck on a chat queue when a send breaks, can cost far more in time and missed revenue. For non-technical teams, support and ease of use are worth a premium — which is why our overall pick across the site is Constant Contact even though it's seldom the cheapest. Decide what you're optimizing for: the lowest bill, or the least friction.

Frequently asked questions
How much does email marketing software cost?
For a small list (a few thousand contacts) emailed a few times a month, expect roughly $0–$60 per month depending on the tool and model. Free tiers exist (Brevo, MailerLite, Mailchimp have limited ones), while a tool like Constant Contact starts around $12/month. Costs rise as your list grows — use the calculator above to estimate your specific case.
Which email marketing tool is cheapest?
It depends on your list size and how often you send. Brevo's pay-per-email model is usually cheapest for large lists emailed occasionally; MailerLite is often cheapest for small, frequently-emailed lists. Per-contact tools converge in price at higher list sizes. There is no single cheapest tool for everyone — the calculator shows the answer for your numbers.
Why does the price jump as my list grows?
Per-contact tools price in tiers, so crossing a threshold (say from 2,500 to 2,501 contacts) bumps you to the next bracket. That's why a list that doubles can more than double your bill on some plans, and why it pays to price a tool against the list size you expect in a year, not the one you have today.
