The math on Mailchimp stops working surprisingly early. Once your list crosses 5,000 subscribers, the Standard plan jumps to $75 a month. At 25,000 it’s $230. At 100,000 you’re at $800 - more than ActiveCampaign at the same volume, despite ActiveCampaign having dramatically better automation. Mailchimp built its brand on “free for small senders” and quietly became one of the most expensive options for anyone who actually grew.

Combine that with the fact that Mailchimp’s automation builder hasn’t materially improved in three years, deliverability has slipped, and CRM features feel bolted on - and the case to leave is strong. Here are the five alternatives that actually deliver.

Why Marketers Replace Mailchimp

Three issues come up over and over. First, list-based pricing means every duplicate, every bounce that didn’t get pruned, every “audience” you forgot about, costs money. Mailchimp profits from your sloppiness. Second, the automation logic is shallow - branching, waits, and conditional splits exist but feel like a 2018 product. Third, the recent push toward “all-in-one” features (CRM, websites, appointment booking) has spread the product thin. None of those bolted-on features are best-in-class, and they make the core email tool feel like a side concern.

The 5 Best Mailchimp Alternatives

1. ActiveCampaign - Best Overall

ActiveCampaign:  ★★★★☆ 4.5/5

ActiveCampaign starts at $19 per month (Lite, 1,000 contacts) and scales to $79 (Plus), $159 (Professional), $279 (Enterprise). Pricing is based on contacts, not “audiences” - one contact is one contact regardless of how many lists they’re on.

The automation builder is the headline feature and it’s genuinely a generation ahead of Mailchimp’s. Multi-step branching with conditions on tags, custom fields, behavior, and time delays - all in a visual builder that doesn’t get cramped at 30+ steps. The CRM features (deals, pipelines, lead scoring) are credible enough to replace a separate sales tool for teams under 20.

Pros

  • Visual automation builder supports if/else branching, split actions, wait-until conditions, and goal-based exits — far deeper than Mailchimp's journey builder
  • Site Tracking and Event Tracking tie on-site behavior (page visits, form fills, video plays) directly to automation triggers without extra tooling
  • Built-in CRM with deal pipelines includes per-deal automation — e.g., auto-send a proposal email when a deal moves to 'Negotiation' stage
  • Predictive Sending uses machine learning to deliver each email at the individual contact's peak engagement window
  • Deliverability consistently ranks #1 in independent tests (EmailToolTester) thanks to dedicated IP options and DKIM/SPF management

Cons

  • No free plan — Starter begins at $29/mo for 1,000 contacts, making it 2x the cost of Mailchimp for beginners
  • Email template builder lacks Mailchimp's polish; templates feel dated and the drag-and-drop editor has limited design flexibility
  • Landing page builder is only available on Marketing plan ($49/mo+) and offers fewer templates than dedicated tools like Unbounce
  • Reporting dashboards require manual setup; there are no pre-built executive summaries or one-click campaign comparison views

What’s missing: the email designer is functional but uninspired. Mailchimp’s drag-and-drop builder and template gallery are visually nicer.

2. Brevo - Best Value

Brevo:  ★★★★☆ 4.4/5

Brevo (formerly Sendinblue) charges by emails sent rather than contacts stored. Free for up to 300 emails per day. Starter is $25 per month for 20,000 emails, Business $65 for 20,000 with advanced features. Unlimited contacts on every paid tier.

For lists with high subscriber counts but low send frequency, Brevo can be 70-80% cheaper than Mailchimp. A 50,000-contact list that sends one newsletter a week costs ~$25 a month on Brevo versus ~$350 on Mailchimp. This pricing model is the underrated story of the email market.

Pros

  • Pricing is based on email volume (not contact count), so you can store 100,000 contacts on the free plan and only pay when you send more than 300 emails/day
  • Built-in SMS campaigns reach 60+ countries and WhatsApp Business messaging is available natively, unlike Mailchimp which requires a third-party SMS add-on
  • Transactional email API handles order confirmations, password resets, and shipping notifications with dedicated IP starting at the Business plan ($18/month)
  • GDPR compliance features include EU-hosted servers, double opt-in forms, consent tracking, and automatic unsubscribe list management
  • Starter plan at $9/month for 5,000 emails/month undercuts Mailchimp Essentials ($13/month for 500 contacts) for shops with large contact lists but low send frequency

Cons

  • Drag-and-drop email editor offers fewer design blocks and template variety than Mailchimp's builder, which includes 100+ pre-styled layouts
  • Free plan adds a Brevo logo to the footer of every email, and removing it requires the Starter plan at $9/month
  • Deliverability rates on the free and Starter plans use shared IP addresses; dedicated IP requires the $18/month Business plan
  • Reporting is limited to opens, clicks, and unsubscribes; click heatmaps, device analytics, and revenue attribution require the Business plan

The trade-offs: deliverability is good but not elite, the automation builder is solid but less powerful than ActiveCampaign’s, and the UI translation occasionally has rough edges (Brevo is a French company).

3. Klaviyo - Best for Ecommerce

Klaviyo’s free tier covers 250 contacts and 500 emails per month. Paid plans start at $20 (500 contacts) and scale steeply with list size - $150 for 10,000, $700 for 50,000.

For Shopify, WooCommerce, and BigCommerce stores, Klaviyo is the best email tool, period. The product-, order-, and behavior-based segmentation is unmatched. Predictive analytics (next-order date, customer lifetime value, churn risk) are baked into segments and flows. Klaviyo’s revenue attribution is also more honest than Mailchimp’s, which helps you stop optimizing for vanity opens.

The catch: it’s expensive at scale, and overkill for non-ecommerce use cases. A B2B newsletter doesn’t need Klaviyo.

4. ConvertKit - Best for Creators

ConvertKit (recently rebranded Kit) is free up to 10,000 subscribers, then scales to $25 per month (1,000 contacts on Creator) and $50 (Creator Pro). The free tier is the most generous on this list.

ConvertKit is built for newsletter authors, course creators, and solo brands. The tag-based subscriber model is more intuitive for content workflows than Mailchimp’s audiences. Landing pages, opt-in forms, and tip jars are tightly integrated. The new Creator Network feature (one-click cross-promotion) is unique.

For ecommerce, ConvertKit is the wrong tool. For a writer with a paid newsletter, it’s the right one.

5. MailerLite - Best for Beginners

MailerLite is free up to 1,000 subscribers and 12,000 monthly emails. Growing Business is $9 per month (500 contacts), $69 (10,000 contacts). Advanced is $18-$139 across the same tiers.

MailerLite is the cleanest UI on this list, full stop. New marketers get productive in an afternoon. The pricing is the most reasonable in the segment, the templates are tasteful, and deliverability is solid.

The trade-off: automation is more limited than ActiveCampaign, the integration ecosystem is smaller, and customer support takes longer to respond on the free tier.

Who Should Choose Which

Choose ActiveCampaign if your email marketing is sophisticated - multi-step automations, behavior-based segmentation, sales-marketing alignment.

Choose Brevo if you have a large list with moderate send frequency. The send-based pricing is a legitimate cheat code.

Choose Klaviyo if you run an ecommerce store. Don’t even consider the others.

Choose ConvertKit if you’re a creator, author, or course seller selling to individual fans.

Choose MailerLite if you’re new to email marketing or just want clean simplicity at a fair price.

Pricing at 25,000 Contacts (Annual)

  • Mailchimp Standard: $2,760
  • ActiveCampaign Plus: $1,716
  • Brevo Business (50k emails/mo): $780
  • Klaviyo: $4,200
  • MailerLite Advanced: $1,668
  • ConvertKit Creator Pro: $1,716

Brevo wins on pure cost. ActiveCampaign and MailerLite tie for best feature-per-dollar.

Frequently Asked Questions

Can I migrate my Mailchimp list cleanly?

Yes. All five tools have official Mailchimp importers that handle subscribers, tags/groups, and basic segments. Automations don’t migrate - you’ll rebuild those. Plan on a half-day for the import and another two days to recreate flows.

Which has the best deliverability?

Klaviyo and ActiveCampaign both lead independent deliverability tests in 2025-2026. MailerLite and Brevo are close behind. Mailchimp’s deliverability has slipped to mid-pack and is the underrated reason to leave. We discuss deliverability in our ActiveCampaign vs Mailchimp comparison.

Do any of these include landing pages?

ActiveCampaign, Brevo, ConvertKit, and MailerLite all include landing page builders. Quality varies - ConvertKit and MailerLite produce the best-looking pages by default. Klaviyo’s landing pages are more limited.

What about SMS marketing?

ActiveCampaign, Brevo, and Klaviyo all have built-in SMS. Klaviyo’s SMS is the most mature for ecommerce. ConvertKit and MailerLite require third-party integrations.

The Verdict

For most teams leaving Mailchimp, ActiveCampaign is the strongest all-around replacement. The automation depth pays for itself within months for any team running serious lifecycle email. Brevo wins on value if you’re price-sensitive and your sending isn’t too frequent. Klaviyo is non-negotiable for ecommerce.

Mailchimp’s golden era was real, but the industry kept moving and Mailchimp didn’t. Pick the alternative that matches your business model and don’t look back.
