Our top pick for most businesses in 2026 is Klaviyo if you sell products and ActiveCampaign if you sell services — the category no longer has one winner, because pricing and automation models diverge sharply by business type. Mailchimp remains the easiest starting point, Brevo is the value pick for teams sending high volume to modest lists, and Kit is purpose-built for creators monetizing an audience. Every price here was re-verified within the last 30 days, and rankings come from our published formula rather than commercial relationships.

Best for ecommerce brands that need catalog-driven flows and revenue attribution
Klaviyo is an ecommerce customer database that happens to send email. Deep Shopify integration, catalog-aware flows and per-flow revenue attribution make it the category standard for product sellers, at a price that rises fast with list size.
Free plan
paid from $20/mo
Best for B2B and service businesses that need real automation and lead scoring
ActiveCampaign has the deepest automation builder available to small businesses, with conditional branching, lead scoring and a built-in CRM. It is the strongest fit for B2B and service businesses whose email leads to a sales conversation.

Best for creators monetizing an audience with newsletters and digital products
Kit (formerly ConvertKit) is email marketing narrowed deliberately to creators: newsletters, tagging instead of lists, and native paid subscriptions. Outside that audience it looks feature-poor; inside it, the focus is the point.
Free plan
paid from $25/mo
Best for large lists mailed occasionally, where send-based pricing wins
Brevo (formerly Sendinblue) prices by email volume rather than contact count, which makes it dramatically cheaper for large lists mailed occasionally. Feature depth is mid-tier, but the value equation is the strongest in the category for the right sending pattern.
Free plan
paid from $9/mo
Best for first-time senders who want the shortest path to a good-looking campaign
Mailchimp is the most widely known platform in the category and still the easiest first send. Under Intuit it has gained polish and price increases in equal measure, and serious ecommerce or automation work now has better-fitting alternatives.

Buyer's guide
This is the pricing fork that decides your five-year cost. Mailchimp, Klaviyo, ActiveCampaign and Kit charge primarily by how many contacts you store; Brevo charges primarily by how many emails you send. If you have a large list you mail occasionally, send-based pricing can be dramatically cheaper. If you mail a small list constantly, contact-based pricing wins. Model both against your actual list growth before you commit, because migrating a warmed list is genuinely painful.
Ecommerce lives or dies on behavioral triggers tied to catalog and order data — that is Klaviyo's entire architecture and why product sellers pay its premium. B2B and service businesses need lead scoring, CRM-shaped contact records and conditional branching, which is ActiveCampaign's strength. Creators need frictionless broadcasts, tagging and paid subscriptions, which is what Kit optimizes for. Buying against the wrong motion is the most common expensive mistake in this category.
Every platform on this list has competent infrastructure. Inbox placement is determined far more by your authentication and list hygiene than by vendor choice: set up SPF, DKIM and DMARC on day one, use double opt-in, and suppress non-openers on a schedule. Treat any vendor claiming a specific inbox rate as marketing rather than a spec.
Ask what you can export and how. Contacts and unsubscribes are portable everywhere; automations, templates and historical engagement usually are not. Assume you will rebuild your flows if you move, and weight the "will we outgrow this" question accordingly.
FAQ
It depends on your list-to-send ratio. Contact-based pricing (Mailchimp, Klaviyo, ActiveCampaign, Kit) suits small lists mailed frequently. Send-based pricing (Brevo) suits large lists mailed occasionally — a 40,000-subscriber newsletter sent monthly is dramatically cheaper this way. Calculate both against your actual sending pattern before committing, because migrating a warmed list later is genuinely painful.
Kit has the most generous free tier at up to 10,000 subscribers with unlimited broadcasts, landing pages and even paid-subscription selling — unmatched if you are a creator. Brevo is free for unlimited contacts at 300 emails per day, which suits large dormant lists. Mailchimp free covers 500 contacts and 1,000 monthly sends and is the easiest to learn. Klaviyo free covers 250 profiles with the full segmentation engine, so ecommerce brands can test the real product.
Far less than people expect. Every platform on this list runs competent sending infrastructure; inbox placement is driven mainly by your own authentication and list hygiene. Set up SPF, DKIM and DMARC on day one, use double opt-in, and suppress non-openers on a schedule. Any vendor promising a specific inbox rate is marketing rather than quoting a spec.
Contacts and unsubscribe records are portable everywhere and should be exported before you need them. What does not move is everything else: automations, templates, segment definitions and historical engagement data generally have to be rebuilt. Assume a rebuild when you evaluate, and weight the "will we outgrow this" question accordingly — it is the main reason we recommend buying slightly ahead of your current needs.
