Rule vs Mailchimp: Platform Overview

Rule is a Swedish marketing automation platform built for companies that want to grow through customer journeys, personalization, and multi-channel communication across email, SMS and RCS. It focuses heavily on automation-first marketing, making it particularly strong for businesses that want to scale their communication without increasing manual work.

Mailchimp started as a newsletter tool and has evolved into a broader marketing platform. It is widely known and easy to get started with, especially for smaller teams or companies new to email marketing.

Both platforms are powerful but they are built with slightly different priorities.

Ease of Use & Editor Experience

Rule focuses on flexibility and automation. Its drag-and-drop editor is modern, user-friendly, and built to support dynamic content and segmentation from the start. It allows marketers to build advanced campaigns and automation without being a marketing automation specialist. By automatically customizing templates to match your brand, Rule makes it possible for users to send their first campaigns in minutes. Rule also encourages marketers to think in customer journeys, where emails, SMS, and triggers work together. This makes it particularly useful for lifecycle marketing, onboarding flows, and behavioral campaigns.

Mailchimp’s editor is widely appreciated for its simplicity. It also offers a drag-and-drop interface, a large template library, and AI-generated content suggestions. This makes it easy for beginners to create campaigns quickly. However, more advanced automation and segmentation features often require upgrading to higher-tier plans.

In practice, this means Mailchimp is slightly easier at the beginning, while Rule becomes more powerful as your marketing grows and is easier to scale.

Automation & Customer Journeys

Automation is where the difference becomes clearer.

Rule is built with automation at its core. You can create customer journeys triggered by behaviors, timing, segmentation, or external events. This makes it well suited for companies that rely on lifecycle communication such as onboarding flows, retention campaigns, promotions and personalized engagement.

Mailchimp also offers automation, but the flexibility depends heavily on the pricing tier. Basic automation is available on lower plans, while more advanced journeys and predictive features are locked behind higher-priced packages.

For companies planning to scale their marketing automation, Rule often provides more flexibility earlier.

Channels & Communication Capabilities

Rule supports email, SMS, and RCS messaging within the same platform. This makes it easier to create consistent customer journeys across channels without relying on multiple tools. Many companies use this to combine transactional messages, marketing campaigns, and lifecycle communication in one place.

Mailchimp primarily focuses on email marketing, with SMS available in certain regions. It also includes landing pages, ads, and basic website functionality. This makes Mailchimp suitable for companies that want an all-in-one marketing starter platform, while Rule is more focused on communication, lifecycle marketing and automation depth.

Integrations & Ecosystem

Mailchimp has a larger integration ecosystem, with hundreds of available integrations. This is partly due to its long presence in the market and large user base. Popular integrations include Shopify, WordPress, Salesforce, and many others.

Rule offers a smaller but still strong integration ecosystem, including e-commerce platforms, custom API connections and personalization softwares. For many companies, Rule’s integrations are more than enough, especially when automation and data flexibility matter more than sheer quantity.

Mailchimp wins on number of integrations, while Rule focuses more on flexibility and data-driven automation.

AI & Modern Marketing Capabilities

Both platforms are investing heavily in AI.

Rule focuses on AI-driven personalization, automation optimization, and customer journey intelligence. The platform is designed to help marketers build more relevant communication based on behavior and data, additionally to easily create and adapt content with AI.

Mailchimp includes AI features like content generation, subject line suggestions, and predictive segmentation. These tools are helpful, particularly for teams that want to create campaigns faster.

Mailchimp currently emphasizes AI for content creation, while Rule leans more toward AI-driven automation and personalization for smarter marketing workflows.

GDPR & Data Privacy

For many European companies, GDPR compliance is a key factor.

Rule is based in Sweden, meaning it operates within European data privacy frameworks. This can simplify compliance requirements for companies working primarily within the EU. The servers are based in Europe to ensure the highest level of security.

Mailchimp is US-based and relies on international data transfer frameworks. While compliant, this may require additional legal considerations for some organizations, particularly those with strict data policies.

This makes Rule especially appealing for companies prioritizing European data handling and GDPR alignment.

Pricing Comparison

One key difference between Rule and Mailchimp is how pricing and email sending limits work.

Mailchimp offers tier-based pricing with a free plan, which makes it attractive for small businesses starting out. Their combined pricing model is based on contacts and email sends. When choosing a plan, you select a contact limit, but each plan also includes a monthly email send limit. However, costs often increase quickly as contact lists grow, the amount of send out increases and advanced features are needed.

Rule also offers a free plan but uses a more flexible pricing structure based only on the business contact list with the possibility to send out unlimited emails and communicate as often as needed. This can make Rule more cost-efficient for growing companies that want to perfect their email marketing or need advanced automation.

This means that while Mailchimp can work well for occasional senders, businesses that rely heavily on automation, frequent newsletters, or multi-channel communication may find Rule’s unlimited sending model more predictable and scalable as they grow.

Support & Customer Experience

Support is an often overlooked but nethertheless an important factor when choosing an email marketing platform, especially as your needs grow.

With Rule, support is both personal and accessible. You get localized support from real people, with the option to call or email whenever needed. Inside the platform, the AI assistant Cheffy helps you with quick answers and guidance as you work. Rule also offers their Help Center with documentation and videos, making it easy to find answers on your own when it suits you.

Mailchimp offers support mainly through documentation, chat, and email depending on your plan. Access to more direct or prioritized support is often limited to higher-tier subscriptions.

In practice, Rule is a strong choice for teams that value hands-on, personal support combined with self-service resources, while Mailchimp leans more toward self-service unless you upgrade.
