Pricing and Value
Mailchimp: Offers an accessible free plan and affordable entry pricing. However, advanced features, priority support, and higher limits require premium plans. Pricing can increase substantially as your subscriber list grows, especially because Mailchimp counts duplicate contacts across lists.
ConvertKit: Transparent, flat-rate pricing with all features included at every tier (except a recent Creator Pro addition). No extra charges for duplicated contacts, making it much more economical for large lists with segmentation needs.
ActiveCampaign: More expensive upfront, but includes extensive automation, CRM, and deep segmentation even on lower tiers. Its Starter Marketing Plan is often viewed as offering better overall value for advanced users due to comprehensive features.
List Management & Segmentation
Mailchimp: List-based system, each audience lives in a separate list. Works well for distinct brands but leads to paying multiple times for the same subscriber if they're in more than one list.
ConvertKit: Tag-based system. All subscribers are managed in a single list but can be filtered and segmented with tags or custom fields. No duplicated contacts, efficient for managing complex segmentation.
ActiveCampaign: Combines robust list management and tagging. Supports advanced segmentation based on behavior, engagement, and custom fields.
Key Point: For SaaS companies and fast-growing lists, ConvertKit’s and ActiveCampaign’s systems prevent billing inefficiencies and reduce complexity compared to Mailchimp’s traditional list-based approach.
Automation Capabilities
Mailchimp: Basic automation for welcome series, abandoned carts, or triggered emails. More advanced automation features are only available on higher-tier paid plans.
ConvertKit: Visual automation builder is highly intuitive with branching logic. Excellent for creators running product launches, evergreen funnels, or complex sequences—without leaving the platform.
ActiveCampaign: Industry leader in automation depth. Allows for conditional flows, advanced triggers, multi-channel automation (including messaging and SMS), and integrated CRM actions. Ideal for businesses seeking granular control over every step of the customer journey.
Deliverability and Reliability
Deliverability is a non-negotiable consideration in email marketing software comparison.
ActiveCampaign: Stands out with strong sender authentication tools, integration with third-party list-cleaning services, feedback loop data, and stricter controls for list hygiene. Recently, industry reports show ActiveCampaign leading in deliverability rankings due to these proactive features.
Mailchimp: Covers deliverability basics such as bounce handling and authentication but lacks advanced tools like deliverability dashboards or built-in list cleaning. This may affect sender reputation for high-volume senders.
ConvertKit: Offers standard deliverability features along with solid sender reputation management, but does not extend to the depth of ActiveCampaign in terms of reporting and list hygiene.
2025 Update: According to recent industry reviews, active deliverability management and sender health tools have become crucial due to evolving ISP filtering. ActiveCampaign’s ongoing enhancements give it a measurable edge in this area.
Integrations & Extensibility
Mailchimp: 300+ integrations with platforms including Shopify, WooCommerce, and major CRMs. Suitable for teams needing a connected, all-in-one toolset.
ConvertKit: About 90 integrations focused on creator tools (e.g., Stripe, WordPress, Teachable). Can connect to hundreds more via Zapier, but native e-commerce connections are limited.
ActiveCampaign: Over 250 direct integrations, including e-commerce, support systems, and SaaS tools. API and custom connectors allow for extensive workflow customization.
