“How much does email marketing cost?” is one of those questions with a frustrating answer: it depends — but not on anything mysterious. The price is driven by a handful of variables you can actually predict, and the published “starting at” figures rarely reflect what you’ll really pay once your list grows. This breakdown walks through what you’re paying for, what the major platforms charge in 2026, and where the hidden costs hide so you can budget honestly instead of getting surprised at your second invoice.
What you’re actually paying for
Email platforms almost all price on one of two models: by the number of contacts you store, or by the number of emails you send. That distinction matters more than the sticker price. If you have a large list but email it infrequently, a send-based platform is far cheaper. If you email a small list constantly, a contact-based plan can be the better deal. On top of the base fee, you’re paying for deliverability infrastructure, automation, templates, reporting, and support — the things that separate a real platform from a raw sending API.
The cost ladder: free, entry, and scale
Most businesses move through three stages. Free plans from providers like Mailchimp, Brevo, and MailerLite are genuinely usable for getting started — Mailchimp’s free tier covers up to 500 contacts and around 10,000 monthly sends, and many small businesses stay on free plans indefinitely. Entry paid plans typically run $9–$20 a month and unlock automation, better deliverability, and the removal of vendor branding. Scale is where the real money appears: as your list crosses several thousand contacts, monthly costs can jump severalfold, which is exactly where the pricing model you chose at the start starts to bite.
What the major platforms charge in 2026
| Platform | Free plan | Paid starts at | Pricing model | Roughly at 5,000 contacts |
|---|---|---|---|---|
| MailerLite | Up to 500 subscribers, 12,000 emails/mo | ~$10/mo | By subscriber count | Among the cheapest at scale |
| Brevo | 9,000 emails/mo, unlimited contacts | ~$9/mo | By emails sent | Low if you send infrequently |
| Mailchimp | 500 contacts, ~10,000 sends/mo | ~$20/mo (Standard) | By contact count | ~$100/mo (Standard) |
| Constant Contact | None | ~$12/mo (Lite) | By contact count | ~$110/mo (Standard) |
| Klaviyo | Up to 250 contacts | ~$20/mo | By contact count (SMS separate) | $100+ for larger lists |
The pattern is clear: entry prices cluster around $9–$20, but the gap widens sharply as lists grow. Mailchimp tends to run 2–3× pricier than leaner competitors at the same contact count, and Constant Contact — which has no free tier — costs more than Mailchimp Standard at every step. Klaviyo is the premium ecommerce option: powerful for Shopify stores, but its contact-based pricing and separate SMS billing make it one of the costlier choices for a general newsletter.
The costs nobody puts on the pricing page
Several charges only surface later. Overage fees apply when you exceed your send or contact limit — Brevo, for instance, charges around $0.002 per email above your plan’s allowance. List bloat is the quiet killer on contact-based plans: every unengaged subscriber you keep paying to store is dead weight, which is why regular list cleaning is a cost-control measure, not just a deliverability one. And dormant SMS or add-on contacts can inflate bills on platforms that bundle channels. Budget for the plan you’ll be on in a year, not the one you sign up for today.
How to keep the bill honest
Match the pricing model to your actual habits before anything else: send-based if your list is large and quiet, contact-based if it’s small and active. Prune unengaged subscribers on a schedule. Start on a free tier to validate that email works for you before paying, and only upgrade when you hit a specific limit — automation, contacts, or branding removal — that’s genuinely blocking you. The goal is to pay for capability you use, not headroom you don’t.
Frequently asked questions
Is free email marketing software good enough to run a business on?
For early stages, often yes. Free tiers from Mailchimp, Brevo, and MailerLite include real sending, basic automation, and templates. You’ll outgrow them when you need advanced automation, larger volume, or branding removal — but there’s no need to pay before then.
Why does my bill jump so much as my list grows?
Because most plans price by contacts or sends, and both rise with your list. A jump from a few hundred to a few thousand contacts can multiply a contact-based bill several times over. Choosing the right pricing model early softens this.
Is send-based or contact-based pricing cheaper?
It depends on your send frequency. Large list emailed rarely → send-based (like Brevo) wins. Small list emailed often → contact-based can be cheaper. Estimate your monthly sends and your contact count, then compare both ways.
Once you understand the cost structure, the next step is matching a specific tool to your needs — and learning the platform well enough to use what you’re paying for. See our guides to choosing the right email marketing software and becoming an email marketing expert.
