How to use this comparison
The ranked list on the right updates as you type — it shows your cheapest options right now and flags when you'll hit a price jump. The milestone table below is the most useful for long-term planning: find the column closest to where you expect to be in 12–24 months and compare costs there, not just at your current size.
Crossover points matter. A provider that's free at 5,000 subscribers might cost more than a paid-from-day-one alternative at 25,000. If you're growing quickly, optimise for the cost at your likely 12-month subscriber count, not today's number.
Feature differences aren't captured here — this is a pure cost comparison. Klaviyo's ecommerce integrations, ActiveCampaign's automation depth, and Kit's creator focus may justify a higher price depending on how you use email.
About this tool
Enter your current subscriber count and monthly list growth rate to see the monthly cost for each major email provider side by side, ranked cheapest first. The tool also projects when you'll hit each provider's next pricing tier based on your growth, and shows a milestone cost table so you can spot crossover points — where a cheaper provider today becomes more expensive at scale.
Frequently asked questions
How accurate are these prices?
Prices are approximate as of mid-2025 and sourced from each provider's public pricing page. Email providers change their pricing frequently — Mailchimp and Kit have both restructured their plans multiple times in recent years. Always verify on the provider's website before committing. Links to each pricing page are shown next to each provider's name.
Why is Brevo handled differently?
Brevo (formerly Sendinblue) prices by emails sent per month, not by subscriber count. A list of 10,000 subscribers sending 4 emails per month = 40,000 emails sent. The tool uses your "sends per month" input to convert subscriber count to email volume for Brevo's comparison. Brevo's model can be cheaper if you send infrequently; it gets expensive if you email your whole list daily.
Kit shows $0 up to 10,000 subscribers — is that right?
Kit's free Newsletter plan allows up to 10,000 subscribers with no monthly charge, but it's limited — no automations, no sequences, and no paid newsletter features. The paid Creator plan unlocks those and starts at around $119/month above 10,000 subscribers. If you need automations, treat Kit as a paid-from-the-start tool.
Which provider is best for ecommerce?
Klaviyo is the dominant choice for Shopify and WooCommerce stores because of its native integrations and revenue attribution. It's significantly more expensive at scale but typically earns back its cost in revenue-driven automations (abandoned cart, post-purchase flows). Mailchimp and ActiveCampaign are better value for stores where email is primarily broadcast, not behavioural.
What does "next tier" mean?
Every provider has pricing brackets — you pay a flat rate within each bracket and jump to the next when you exceed the upper limit. "Next tier" is the subscriber count where your monthly cost increases. The tool calculates how many months until you hit it based on your growth rate, so you can budget for the jump in advance.
