Email is the most reliable direct channel in digital marketing. Social media algorithms throttle your reach — organic reach on Facebook business pages dropped below 5% by 2024. SEO takes months to compound, and most websites never rank for competitive terms. Paid ads stop the moment you stop paying, and customer acquisition costs on major ad platforms have increased over 300% since 2015. An email list is yours: you own the relationship, the addresses, and the ability to reach your audience whenever you have something worth saying.
The platform you use to manage that list shapes your strategy, your revenue potential, and the kind of email marketing you end up doing. A tool designed for retail promotional emails will fight you when you try to build a creator funnel. A tool designed for newsletter operators will limit you when you need sophisticated e-commerce automation. The choice is not just about features — it is about which tool's design philosophy matches yours.
Mailchimp built its reputation as the friendly, accessible email marketing tool for small businesses. For a decade it was the default choice, the one with the chimp logo that appeared in virtually every small business newsletter. ConvertKit entered the market in 2013 with a specific thesis: the tools available to creators were designed for businesses, and creators needed something different. Beehiiv is the newest entrant, founded by people who built Morning Brew's newsletter infrastructure and who believe that a newsletter can be a standalone media business with its own monetisation model baked in from day one.
These three platforms represent three distinct visions of what email marketing is for. Mailchimp is for businesses sending marketing emails and campaigns. ConvertKit (now rebranding as Kit) is for creators building subscriber relationships and selling products. Beehiiv is for newsletter operators building a reader business. Understanding that distinction is more important than comparing feature lists.
"Your email platform is not just a sending tool. It is the infrastructure for the most personal relationship you have with your audience. Choose the one that matches your revenue model, not the one with the most recognisable brand."

Why Email Still Dominates: The Data Behind the Channel
Before comparing the tools, it is worth grounding the decision in why email marketing deserves serious platform selection in the first place.
According to Litmus's 2025 State of Email report, email marketing delivers an average return of $36 for every $1 spent — a figure that has remained relatively stable even as digital advertising costs have risen. The average email open rate across industries hovers around 21.5% according to Mailchimp's own benchmark data, but for engaged creator and newsletter audiences, open rates of 40-60% are achievable and common.
List ownership is the decisive argument. A Facebook page with 100,000 followers reaches perhaps 3,000-5,000 of them organically per post. An email list of 10,000 subscribers with a 40% open rate reaches 4,000 people who actively chose to read your content. When a platform algorithm changes, your social following can effectively disappear overnight. Email is immune to this. The list is yours regardless of what any platform decides.
Subscriber lifetime value compounds in ways social followers do not. A reader who stays on your email list for three years and regularly opens your content is worth orders of magnitude more than a follower who saw two posts. The economics favor building an email relationship.
The platform you build on determines whether you capitalize on these advantages or leave them untapped.
Pricing: List Size Economics and Where Each Platform Hurts
Mailchimp
Mailchimp's pricing is list-size-based, and the cost escalates rapidly as your audience grows. The free tier covers 500 contacts. Essentials starts at $13/month for 500 contacts and scales by contact count. At 10,000 contacts, Essentials runs approximately $80/month. At 50,000 contacts, you are looking at $270+/month.
Mailchimp also counts the same subscriber multiple times if they are on multiple lists, which has historically led to inflated billing for segmented audiences. This is a well-documented complaint. The practice of charging per contact on each list, rather than per unique subscriber, can make Mailchimp genuinely expensive for businesses with complex segmentation requirements where the same contact belongs to multiple audience segments.
Premium at $350/month base is aimed at larger organisations and includes advanced segmentation, unlimited seats, and priority support.
A useful illustration: a marketing agency managing separate lists for ten small business clients could be paying for the same contacts multiple times depending on how lists are structured. This is an architectural problem with Mailchimp's data model that persists despite years of user complaints.
ConvertKit (Kit)
ConvertKit's free tier is notably generous: up to 10,000 subscribers with unlimited email sends, a landing page builder, and basic forms. This is the most generous free tier of the three for growing lists, and it has been a significant customer acquisition tool — many creators built their first list on ConvertKit's free tier before upgrading.
The paid Creator plan starts at $25/month for up to 1,000 subscribers. This seems counterintuitive given the free tier allows 10,000 subscribers, but the distinction is in features: paid plans unlock automation, premium support, and newsletter referral network access. Creator Pro at $50/month adds advanced reporting, Facebook custom audiences integration, and subscriber scoring.
ConvertKit's pricing scales with subscriber count. At 50,000 subscribers, Creator Pro runs approximately $379/month. This is expensive for high-volume list operators but reflects the creator market's willingness to pay for a tool aligned with their specific workflows. The question is always whether the automations and creator-specific features justify the cost differential versus alternatives at the same list size.
Beehiiv
Beehiiv launched with a genuinely competitive pricing structure. The free tier supports up to 2,500 subscribers with core newsletter functionality. The Scale plan at $39/month unlocks premium features. Max at $99/month adds full ad network access, custom domains on multiple publications, and advanced segmentation.
Beehiiv's pricing model is notably different from Mailchimp's: it is flat-rate by tier rather than purely list-size-based at lower subscriber counts. A newsletter with 8,000 subscribers pays the same Scale rate as one with 1,000. This makes costs predictable as you grow, which matters for newsletter operators who are trying to model revenue against expenses.
For newsletter operators in the 1,000 to 25,000 subscriber range, Beehiiv's pricing is often the most competitive of the three when you factor in the native monetisation features included in the plan price. Those features — paid subscriptions, ad network access, referral programs — would require separate tools and their associated costs on Mailchimp or ConvertKit.
Automations: Where ConvertKit Leads
Email automation is the feature that separates a basic newsletter tool from a genuine marketing platform. The ability to send the right email to the right person at the right time, based on their behaviour and interests, is what makes email marketing scalable and proportional to list size.
ConvertKit's Visual Automation Builder
ConvertKit's automation system is built around a tag-and-sequence model that is particularly well-suited to creators. When a subscriber downloads a lead magnet, they get tagged and enter an automated sequence. When they purchase a product, they get a different tag that triggers a different sequence. When they click a specific link, they get moved to a segment that receives more targeted content.
The visual automation builder lets you design these flows graphically — drag and drop triggers, conditions, and actions in a branching diagram. A creator running an online course business, a membership community, and a free newsletter simultaneously can build automation sequences that manage the complexity of multiple subscriber journeys without requiring a developer or complex integration.
A practical example: a creator sells a $197 course on photography. When someone joins the free newsletter, they enter a 5-email welcome sequence. If they click the link about camera equipment in email 3, they get tagged as "gear-interested" and receive a separate 3-email sequence highlighting the course. If they buy the course, they are automatically removed from the promotional sequence and added to the student onboarding sequence. This entire workflow, built in ConvertKit, would require multiple tools and custom integration on Mailchimp or significant compromise on Beehiiv.
Mailchimp's Customer Journey Builder
Mailchimp introduced its Customer Journey builder on the Standard plan, which provides a visual automation approach comparable to ConvertKit's at a surface level. It is functional and adequate for most business email automation: welcome sequences, abandoned cart emails for e-commerce, re-engagement campaigns, and promotional sequences.
For businesses using Mailchimp as a marketing tool connected to a Shopify or WooCommerce store, the e-commerce automation features are well-integrated. Abandoned cart sequences, post-purchase follow-ups, product recommendations based on purchase history, and win-back campaigns for lapsed customers work reliably with the Mailchimp-Shopify integration.
The practical limitation is that Mailchimp's automation mental model is campaign-centric rather than subscriber-centric. The tool is designed to send campaigns to lists, not to manage individual subscriber journeys based on nuanced behavioral triggers. This works for retail email but creates friction for creator use cases.
Beehiiv's Automation Limitations
Beehiiv's automation features are the weakest of the three. It handles basic welcome sequences and time-based drip campaigns, but the depth of conditional logic and behavioural automation that ConvertKit provides is not present. The platform is explicitly designed around the premise that great newsletter content, distributed consistently to a growing audience, is more valuable than complex automation architecture.
For newsletter operators whose primary strategy is sending a compelling newsletter and growing through content quality and referrals, this limitation is minor. The automation you actually need is: welcome new subscribers, re-engage inactive subscribers, and deliver paid subscriber content. Beehiiv handles these cases. For operators who want complex automated sales funnels, Beehiiv is the wrong tool and switching later will be painful.
Newsletter Monetisation: Beehiiv's Structural Advantage
This is where Beehiiv separates itself decisively from the other two platforms, and where the founding team's experience building Morning Brew's infrastructure is most visible.
Paid Subscriptions Native
Beehiiv has a native paid subscription system that lets newsletter operators offer premium subscription tiers directly within the platform. The setup is straightforward: create a paid tier, set the price, and Beehiiv handles payment processing (via Stripe), subscriber management, and content gating. The economics are competitive — Beehiiv takes a smaller revenue share than Substack's 10% fee, making it more favorable for operators who reach meaningful paid subscriber numbers.
A newsletter with 10,000 free subscribers and 500 paid subscribers at $10/month generates $5,000/month in gross revenue. At Substack's rate (10%), the operator keeps $4,500. At Beehiiv's flat-fee pricing model (no per-transaction percentage on Max plan), the operator keeps the full $5,000 minus Stripe's 2.9% + $0.30 processing fee. The math compounds as revenue grows.
ConvertKit's Creator Pro tier includes paid newsletter subscriptions, but the implementation is less integrated and requires more setup. Mailchimp has no native paid subscription feature.
Beehiiv Boosts: The Referral and Ad Network
Beehiiv Boosts is a two-sided network that lets newsletter operators earn revenue by recommending other newsletters to their subscribers, and grow their own audience through recommendations from other Beehiiv newsletters. The mechanism: when you publish a new issue, you can include a "Boost" that recommends another newsletter. If your subscriber clicks and subscribes to that newsletter, you earn a payment (typically $1-3 per new subscriber, set by the newsletter being boosted). Simultaneously, your newsletter can offer Boosts to other operators who want to grow.
This creates a network-effect marketplace that benefits from Beehiiv's growing community of newsletter operators. A newsletter with 20,000 engaged subscribers in the personal finance niche can both earn revenue by boosting other finance newsletters and acquire new subscribers from newsletters in adjacent niches. In 2025, some Beehiiv newsletter operators reported earning $3,000-8,000/month in Boost revenue alone.
The Beehiiv ad network connects newsletter operators with advertisers looking to reach niche audiences. For newsletters in specific verticals — technology, finance, health, creator economy, business — the ability to monetise through curated ads without the manual work of a direct sponsorship program is a meaningful revenue stream. Beehiiv handles the ad placement, targeting, and payment infrastructure; the operator receives revenue proportional to their audience size and engagement metrics.
Neither Mailchimp nor ConvertKit has an equivalent native ad network or cross-newsletter referral system. Replicating these features on other platforms requires integrating separate tools (Sparkloop for referrals, direct sponsor outreach, Memberful or Stripe for paid subscriptions) and the associated overhead.
Beehiiv's Analytics Advantage for Newsletter Operators
Beehiiv's analytics are built specifically for newsletter operators, not generic email marketers. The metrics tracked include:
- Open rate by send time to identify when your audience is most engaged
- Subscriber acquisition source so you know which growth channels produce your best readers
- Paid conversion rate showing the funnel from free to paid subscriber
- Churn analysis with reasons and cohort retention data
- Boost performance showing earnings per recommendation
These metrics tell a newsletter operator what is actually working in their business. Mailchimp's analytics tell you click rates and open rates — useful for campaign optimization but not for managing a subscriber business. ConvertKit's analytics are better, particularly for tracking subscriber lifecycle through automated sequences, but they are not designed around the reader-business model.
Deliverability: The Invisible Differentiator
Deliverability — whether your emails actually reach subscribers' inboxes or land in spam — is the most important factor that most people underweight when choosing an email platform.
Spam filtering has become significantly more sophisticated since Google's February 2024 email sender requirements, which mandated that bulk email senders authenticate with SPF, DKIM, and DMARC, and maintain spam rates below 0.1%. These changes raised the floor for what it means to be a legitimate email sender and made platform reputation matter more than individual sender reputation.
Beehiiv has built a strong deliverability reputation partly because its platform is designed specifically for newsletter operators who write content their subscribers want to read. High engagement rates signal to email providers that Beehiiv-sent mail is welcome, which benefits all senders on the platform.
ConvertKit's deliverability is strong, reflecting both good technical infrastructure and a user base oriented toward engaged audiences. The platform's sender reputation benefits from creators sending to opted-in lists with high engagement.
Mailchimp's deliverability is good but more variable, partly because the platform's broader user base includes businesses running bulk promotional email that can depress platform-wide sender reputation. For most users Mailchimp deliverability is fine, but it is the weakest of the three for newsletter operators specifically.
Who Should Use What
Small Business with E-commerce
Mailchimp remains a solid choice for small businesses using Shopify or WooCommerce who want automated abandoned cart emails, order confirmations, and product recommendation campaigns. The e-commerce integrations are mature, the templates are professional, and the customer journey builder handles retail automation adequately. If email is a marketing channel alongside social and paid ads rather than a primary business model, Mailchimp's feature set is sufficient and its brand familiarity means most team members will be able to use it without extensive training.
Course Creators, Bloggers, and Podcasters
ConvertKit is purpose-built for this audience. The tag-based automation lets you build sophisticated subscriber journeys for promoting courses, free challenges, book launches, and product releases without a developer. Its landing page builder and form tools are optimised for the list-building tactics that creators use. The deep integrations with platforms like Teachable, Kajabi, Gumroad, and Stripe mean your email platform and product platform work together without custom development. The generous free tier is a meaningful advantage for creators in the early stages.
A specific use case where ConvertKit excels: a podcaster who also sells a $500 coaching program. New subscribers enter a welcome sequence. Based on what they click — links about the podcast, links about coaching, links about specific topics — they get tagged and added to relevant nurture sequences. The coaching program sequence converts prospects who have already signaled interest. This entire architecture is ConvertKit's native design philosophy.
Newsletter Operators Building a Reader Business
Beehiiv is the clear choice for creators whose newsletter is the product rather than a marketing channel for another product. If your revenue model involves paid subscriptions, sponsorships, and audience growth through referrals, Beehiiv's native infrastructure for all three is a significant advantage over assembling the equivalent capability from separate tools. The platform's design philosophy — that great writing distributed to an engaged audience is a viable business — is coherent and the product reflects it.
Morning Brew, which grew from 0 to 4 million subscribers while using infrastructure that became Beehiiv's foundation, is the clearest proof of concept. The playbook — consistent editorial voice, strong referral program, native ad monetisation — is reproducible at smaller scale.
Established Businesses with Large Lists
Mailchimp Premium or enterprise email marketing platforms with advanced segmentation and compliance features (ActiveCampaign, Klaviyo, HubSpot) may be more appropriate for large organisations with complex requirements. At very large list sizes, the cost-benefit of Mailchimp versus specialist e-commerce platforms like Klaviyo tips toward Klaviyo for direct-to-consumer businesses. For large media organisations building newsletter revenue, enterprise Beehiiv or a custom solution may be appropriate.

Migration Considerations
Switching email platforms is painful but not catastrophic if done correctly. A few practical notes:
Exporting your list from any platform produces a CSV of email addresses, names, and any tags or segments you have created. Most platforms import CSVs without issue. The painful part is rebuilding automations — every sequence, trigger, and conditional logic must be manually recreated in the new platform.
If you are migrating from Mailchimp to ConvertKit, the primary work is translating Mailchimp's list/segment model into ConvertKit's tag model. One Mailchimp segment becomes one or more ConvertKit tags. The mapping is usually straightforward.
If you are migrating to Beehiiv, be aware that the subscriber experience changes — Beehiiv's newsletters have a distinct publication feel rather than a promotional email feel, which is a design choice that serves readers well but may surprise existing subscribers used to a different format.
Allow 30-60 days for migration, including a parallel-run period where you send to both platforms to check deliverability and engagement before fully switching.
Final Verdict
Choose Mailchimp if: you are a small business using email primarily for promotional campaigns, newsletters, and e-commerce automation, and you want the most widely recognised platform with the largest integration library and team familiarity.
Choose ConvertKit if: you are a creator building automated funnels to sell digital products, courses, or memberships, and you need the best tag-based automation and creator-specific integrations available at any price.
Choose Beehiiv if: your newsletter is a standalone media business where paid subscriptions, sponsorship revenue, and audience growth through referrals are your primary monetisation strategies — and you want native tools for all three without integrating separate platforms.

Frequently Asked Questions
Is ConvertKit better than Mailchimp for creators?
Yes, ConvertKit (now rebranding to Kit) is designed specifically for creators and is better suited to creators than Mailchimp for most use cases. ConvertKit's subscriber tagging and segmentation system is more intuitive for building content-based sequences. Its visual automation builder is cleaner. Its landing page and form tools are optimised for growing an email list, not just sending batch campaigns. Mailchimp was built for small businesses sending newsletters and promotional emails, and its interface reflects that origin. For a blogger, podcaster, course creator, or YouTube creator who wants to build and monetise a subscriber relationship, ConvertKit's creator-focused features and community are more relevant.
What makes Beehiiv different from other email newsletter platforms?
Beehiiv is purpose-built for the newsletter-as-a-business model. It includes native features that other platforms treat as expensive add-ons or third-party integrations: a built-in paid subscription system, a referral program that incentivises subscribers to recommend your newsletter, an ad network that connects newsletter operators with advertisers, and publisher analytics that track performance at a more granular level than competitors. Beehiiv was founded by former members of the team that built Morning Brew's newsletter infrastructure, and it shows: the platform is designed by people who understand how newsletter businesses actually generate revenue. For creators whose newsletter is a primary revenue channel rather than a marketing tool, Beehiiv has a meaningful structural advantage.
Is Mailchimp free?
Mailchimp has a free tier that allows up to 500 contacts and 1,000 emails per month. The free tier includes basic email templates, a landing page builder, and standard analytics. However, Mailchimp's free tier has become more restrictive over time, and several features that were previously free (including email scheduling and A/B testing) now require paid plans. Essentials starts at \(13/month for 500 contacts, Standard at \)20/month, and Premium at $350/month. The pricing scales significantly with list size, which is a common complaint among growing businesses. For lists above 10,000 contacts, Mailchimp's pricing becomes expensive relative to ConvertKit and Beehiiv.
Which email platform has the best deliverability?
Deliverability differences between major email platforms are often overstated in marketing materials. All three platforms maintain good sender reputations and DKIM/DMARC authentication when properly configured. Beehiiv has built a strong deliverability reputation, partly because newsletter-focused platforms tend to have engaged subscriber lists (people actively opt in to newsletters they want to read) rather than bulk promotional email lists that depress engagement metrics. ConvertKit's deliverability is solid and well-regarded in the creator community. Mailchimp's deliverability is generally good but can be affected by the diverse range of senders on its platform. The biggest deliverability factor for any platform is your own list hygiene and engagement rates, not the platform itself.
Can Beehiiv replace ConvertKit for a professional creator?
Beehiiv can replace ConvertKit for creators whose primary goal is operating a newsletter business with paid subscriptions and advertising revenue. Its monetisation features are superior to ConvertKit's. However, ConvertKit's automation capabilities are more mature for creators who run complex product funnels: selling online courses, memberships, or digital products through automated email sequences. If your email marketing strategy involves selling products via automated sequences, ConvertKit's tag-based automation and deep integrations with platforms like Teachable, Gumroad, and Stripe are more capable. If your strategy is primarily growing a newsletter audience and monetising through subscriptions and sponsorships, Beehiiv is the stronger choice.
