> Six real Mailchimp alternatives compared on list price, free tier, transactional API access and trigger model, with prices checked on 2026-10-25.

## Alternatives to mailchimp

**Winner:** brevo

**Verdict:** Brevo is the safest replacement for most Mailchimp accounts: similar editor and automation model, volume-based pricing, and a transactional API included on every plan. Pick Customer.io when your triggers come from product events, Resend when email is code, and Klaviyo only if the revenue lives in a store. Stay on Mailchimp if your sends are simple newsletters and your templates are already built.

**Methodology:** This comparison is based on public sources checked on 2026-10-25: each vendor's pricing page, each product homepage (screenshots taken the same day), the product documentation for API and transactional capabilities, and aggregate ratings on G2 and Capterra. We did not run hands-on deliverability or load tests for this edition, so we do not rank on inbox placement. Scores run from 0 to 5 and weight price transparency, trigger and API capability for engineering teams, free-tier usefulness, and aggregated customer ratings. Prices are list prices in USD and change often, so confirm on the vendor page before committing. None of the vendors here pays for placement or has an affiliate relationship with this site.

### Per-product notes

- **brevo** — *Best overall switch*, best for: Teams that want a drop-in Mailchimp replacement with API access, score: 4.4/5
  The closest like-for-like swap: marketing dashboard plus a real transactional API.
- **resend** — *Best for developers*, best for: Developers who want a clean email API plus basic broadcasts, score: 4.1/5
  Best when email is code in your repo, weaker for non-technical marketers.
- **klaviyo** — *Best for e-commerce*, best for: E-commerce stores on Shopify, WooCommerce or BigCommerce, score: 4.3/5
  Strongest on commerce data. Overkill and costly if you only send newsletters.
- **mailchimp** — *Anchor*, best for: The baseline: teams already on Mailchimp templates and audiences, score: 3.9/5
  Fine for newsletters, awkward once you need event-driven flows or API sends.
- **customer-io** — *Best for event-driven flows*, best for: Product teams sending behavior-driven email from app events, score: 4.3/5
  The right pick when triggers are driven by product events, not list segments.
- **activecampaign** — *Best for visual automation*, best for: Small teams that want deep visual automation and CRM, score: 4.2/5
  Powerful automation for marketers, not an API-first sending layer.
- **kit-convertkit** — *Best for creators*, best for: Creators selling courses, products or paid newsletters, score: 4/5
  Good for audience-led businesses, wrong tool for application email.

## FAQ

### What is the best free alternative to Mailchimp?

Kit offers the largest free tier at up to 10,000 subscribers with unlimited broadcasts, aimed at creators. Brevo's free plan sends up to 300 emails a day and includes transactional API access. Resend's free plan covers 3,000 emails a month with a 100 a day cap.

### Which Mailchimp alternative is best for transactional email?

Resend is built around a transactional API with SDKs, SMTP and webhooks. Brevo includes transactional API and SMTP on every plan, and Customer.io includes transactional email on all plans. Mailchimp sells transactional as a separate product.

### Is Brevo cheaper than Mailchimp?

At entry level, yes. Brevo Starter is listed from $9/mo for 5,000 emails, against Mailchimp Essentials at $13/mo for 500 contacts. Real cost depends on your volume and contact count, so compare at your own numbers.

### Which alternative fits event-driven flows from product data?

Customer.io. It accepts events and attributes from an API, SDKs or a CDP and triggers email, push, in-app and webhook messages from a visual workflow builder. Essentials starts at $100/mo.

### Can I migrate from Mailchimp without hurting deliverability?

Yes, if you authenticate the new domain first, import suppression lists before any send, and ramp volume over several weeks while watching bounce and complaint rates.
