Email Marketing: Mailchimp vs Kit vs Beehiiv
A comprehensive comparison of the three leading email platforms for startups and creators in 2025. We analyze pricing, features, growth tools, and monetization to help you choose the right platform.
Choosing an email marketing platform is one of the most important decisions for your GTM strategy. The platform you pick will shape how you build relationships with your audience, monetize your content, and scale your business. In 2025, three platforms dominate the conversation: Mailchimp (the veteran), Kit/ConvertKit (the creator favorite), and Beehiiv (the newsletter-first disruptor). Each serves a distinctly different use case, and picking the wrong one can cost you thousands in migration headaches later.
Key Takeaways
- Beehiiv offers the most generous free tier (2,500 subscribers) and best growth tools for newsletter businesses
- Kit (formerly ConvertKit) is the clear winner for creators selling digital products and courses
- Mailchimp's free tier has shrunk significantly but remains strong for e-commerce and traditional email marketing
- Beehiiv is the only platform with built-in monetization (ads, paid subscriptions, boosts) at every tier
- Kit's visual automation builder is the best in class for complex sequences
- All three are valid choices—your business model determines the winner
How to Choose
Why This Category Matters
Email is the only marketing channel you truly own. Unlike social media where algorithms control your reach, or paid ads where you rent attention, your email list is yours. It's also the highest ROI channel available—studies consistently show $36-42 return per $1 spent on email marketing. For startups, email is how you build direct relationships with early adopters, nurture leads through long sales cycles, and create predictable revenue through launches and promotions. The platform you choose shapes not just how you send emails, but how you grow your list, monetize your audience, and scale your business. Getting this decision wrong means painful migrations later—when your list is bigger and the stakes are higher.
What to Evaluate
Deliverability
A platform with 95% deliverability beats one with 85% every time. Before evaluating features, research each platform's sender reputation. Smaller platforms (Kit, Beehiiv) often have better deliverability than giants like Mailchimp because they have fewer spammers on their networks.
Business Model Alignment
Your monetization strategy should match your platform's strengths. Newsletter businesses need ad networks and paid subscriptions (Beehiiv). Course creators need product sales and advanced automation (Kit). E-commerce needs transactional emails and integrations (Mailchimp).
True Cost at Scale
Don't just look at the starting price. Calculate what you'll pay at 10K, 25K, and 50K subscribers. Beehiiv's flat pricing becomes dramatically cheaper at scale. Mailchimp's per-contact pricing adds up fast. Kit falls in the middle.
Automation Depth
Simple welcome sequences are easy everywhere. But can you build complex conditional flows based on user behavior? Kit's visual automation builder is best-in-class. Mailchimp has powerful but complex Customer Journeys. Beehiiv's automation is intentionally basic.
Growth Tools
How does the platform help you acquire subscribers? Beehiiv leads with referral programs, recommendation networks, and boosts. Kit offers the Creator Network. Mailchimp relies on integrations and your own traffic sources.
Migration Difficulty
Can you easily export your list and move elsewhere? All three allow CSV exports, but automation sequences, tags, and historical data don't transfer. The smaller your list, the easier to switch—don't let this decision calcify.
Questions to Ask Yourself
- 1.Am I building a newsletter as a business, or is email just one channel among many?
- 2.How will I monetize—through ads, paid subscriptions, digital products, or selling services?
- 3.How sophisticated do my automation sequences need to be?
- 4.What's my realistic subscriber count in 12 months? What will the platform cost at that scale?
- 5.Do I need advanced e-commerce integrations (Shopify, WooCommerce)?
- 6.How important is design flexibility vs deliverability?
- 7.Am I technical enough to set up proper DKIM/SPF authentication?
Common Mistakes to Avoid
Choosing Mailchimp because it's familiar
Mailchimp's free tier has shrunk to 500 contacts and costs scale quickly. Newsletter publishers especially overpay for features they don't need while missing growth tools Beehiiv offers.
Underestimating migration pain
Switching platforms means rebuilding automations from scratch, re-warming your sender reputation, and accepting that some subscribers will churn during the transition. Do it while your list is small.
Optimizing for features instead of business model
Picking Kit for its automation when you're building an ad-supported newsletter means you'll lack monetization tools. Picking Beehiiv when you're selling courses means you'll need third-party payment processing.
Not testing deliverability before committing
A platform that looks great in demos may have deliverability issues with your specific audience. Send test campaigns to multiple email providers (Gmail, Outlook, Yahoo) before migrating your full list.
Ignoring the free tier for too long
Free tiers have limitations that hurt growth—Mailchimp removes automation, Beehiiv adds branding. Upgrade once you're serious about growth, or you're handicapping yourself to save $30/month.

Which Should You Choose?
Building a newsletter as a media business
Unmatched monetization options: built-in ad network, paid subscriptions (0% fee), and Boosts for cross-promotion. Growth tools like referral programs are also best-in-class.
Selling online courses or digital products
Kit Commerce handles everything natively—courses, downloads, coaching, memberships. Combined with the best visual automation builder, you can create sophisticated launch sequences.
Running an e-commerce store
Deep integrations with Shopify, WooCommerce, and other platforms. Revenue tracking, abandoned cart automations, and product recommendation emails are all built-in.
Budget-conscious founder just starting out
Beehiiv's free tier (2,500 subs) includes premium features other platforms charge for. No feature gating means you can build a real audience before paying.
SaaS company nurturing leads
Advanced automations let you build complex nurture sequences based on user behavior. Great for onboarding drips, trial conversion campaigns, and customer education.
Agency managing multiple client accounts
Mailchimp Partner program offers multi-account management, white-label options, and client billing. Most clients will already know the interface.
Migration Tips
- Export your list as CSV and import to Beehiiv—subscriber data transfers cleanly
- Recreate your main automations manually (Beehiiv automation is more limited)
- Archive your best-performing email templates as HTML for reference
- Run both platforms in parallel for 2-4 weeks before fully switching
- Expect some unsubscribes from the platform change email—this is normal
- Kit has a dedicated Mailchimp import tool—use it
- Tags don't transfer automatically; plan your tagging strategy before importing
- Automations need to be rebuilt from scratch—start with your most important sequence
- Kit emails are simpler by design; don't try to recreate complex Mailchimp templates
- Your deliverability will likely improve after the switch
- Straightforward CSV export/import for subscriber lists
- Beehiiv accepts Kit-formatted exports with minimal cleanup
- Plan for reduced automation capability—Beehiiv is not automation-focused
- Your growth tools will be significantly better on Beehiiv
- Monetization setup is intuitive—enable ads and subscriptions quickly
- Standard CSV export works cleanly
- You'll gain powerful automation but lose monetization tools
- Plan to replace Beehiiv Ads revenue with Kit Commerce products
- Referral program will need a third-party tool like SparkLoop
- Consider keeping Beehiiv for your newsletter while using Kit for product sales
Bottom Line
Pick Beehiiv if you're building a newsletter business. Pick Kit if you're selling digital products. Pick Mailchimp if you're running e-commerce or need enterprise features.
