If you're a blogger looking to build and monetise an email list in 2026, you've probably narrowed it down to three dominant players: MailerLite (the budget-friendly, feature-rich option), ConvertKit (now rebranded as Kit, the creator-focused automation platform), and Mailchimp (the all-in-one marketing giant). Each platform takes a different approach to pricing, automation, deliverability, and blogger-specific features. This guide breaks down every metric that affects your bottom line — from free tier limits to advanced segmentation — and tells you exactly which email tool maximizes your blog's revenue at 1,000, 5,000, and 25,000 subscribers.

Platform Overview: MailerLite, ConvertKit, Mailchimp in 2026
MailerLite started as an affordable alternative to Mailchimp and has grown into a powerful, user-friendly platform. It offers a generous free tier (up to 1,000 subscribers) and includes advanced features like automation, landing pages, and website builders even on free plans. ConvertKit (now Kit) built its reputation as the go-to platform for creators, bloggers, and online course sellers. It focuses on visual automation builders, subscriber tagging, and deliverability. Mailchimp is the veteran all-in-one marketing platform, offering email, landing pages, social ads, and even a CRM. However, its pricing has become less blogger-friendly over the years.
In 2026, each platform has evolved. MailerLite now offers a native website builder and improved automation workflows. ConvertKit has rebranded to Kit but retains its creator-centric features and added more e-commerce integrations. Mailchimp has raised prices but added advanced segmentation and AI-powered content recommendations. Let's dig into what matters most for bloggers: cost, deliverability, and revenue generated per subscriber.
Free Tiers Compared: What You Get at $0
For new bloggers, the free tier is often the deciding factor. Here's how each platform stacks up in 2026:
| Feature | MailerLite | ConvertKit (Kit) | Mailchimp |
|---|---|---|---|
| Free subscriber limit | 1,000 subscribers | 300 subscribers | 500 contacts |
| Monthly email sends | 12,000 | Unlimited | 1,000/month |
| Automation | ✅ 1 visual workflow | ✅ Limited (visual builder) | ✅ Basic (single email) |
| Landing pages | ✅ Unlimited | ✅ 1 landing page | ✅ 1 landing page |
| Email support | ✅ Yes | ✅ Yes (delayed) | ✅ 30 days |
| Transaction fee on paid products | None | None | None |
| Best for | Budget-conscious beginners | Creators building from scratch | Test-driving email marketing |
Winner for free tier: MailerLite. It offers the highest subscriber limit (1,000), generous email sends, and includes automation and unlimited landing pages at $0. ConvertKit's 300-subscriber limit is very restrictive. Mailchimp's 500-contact limit and 1,000 monthly sends are also limiting for active bloggers.
Pricing at 1K, 5K, 25K Subscribers: Total Cost of Ownership
As your list grows, pricing becomes critical. Below are the monthly costs for each platform at different list sizes (standard plans, no add-ons). Note that Mailchimp's pricing is based on "contacts" including unsubscribed, while MailerLite and ConvertKit bill only for active subscribers.
| List size | MailerLite | ConvertKit (Kit) | Mailchimp (Essentials) |
|---|---|---|---|
| 1,000 subscribers | $0 (free) or $10/mo (growing plan) | $29/mo | $13/mo (500–1,500 contacts) |
| 5,000 subscribers | $30/mo | $59/mo | $45/mo |
| 10,000 subscribers | $55/mo | $99/mo | $80/mo |
| 25,000 subscribers | $120/mo | $199/mo | $175/mo |
Real-world math: 10,000 active subscribers
MailerLite costs $55/month. ConvertKit costs $99/month — that's $528 more per year. Mailchimp costs $80/month. Over three years, MailerLite saves you over $1,500 compared to ConvertKit.
Winner for pricing: MailerLite. It's consistently the most affordable at every tier, and the free tier is the most generous. ConvertKit is expensive but includes unlimited emails and advanced automation. Mailchimp sits in the middle but has become pricier in recent years.
Automation & Sequences: Which Platform Nurtures Better?
Email automation is how you turn new subscribers into buyers. Here's how each platform compares:
- MailerLite: Visual automation builder with triggers (subscribes, clicks, opens, purchases), conditions, actions (send email, add tag, wait). Supports multi-step sequences. Great for basic to intermediate funnels.
- ConvertKit (Kit): Industry-leading visual automation builder. Offers powerful tagging and segmentation. You can build complex rules based on subscriber behaviour across your blog, forms, and purchases. Best for advanced funnels and e-commerce.
- Mailchimp: Customer Journey Builder with branching logic. It's powerful but has a steeper learning curve. Free tier includes basic automation (welcome email), paid plans unlock multi-step journeys.
If you need simple welcome sequences and newsletter broadcasts, MailerLite is sufficient. If you're building sophisticated funnels with conditional logic and custom events, ConvertKit is the winner. Mailchimp is capable but overkill for most bloggers.

Email Deliverability: Getting Your Emails Into Inboxes
Deliverability (the rate at which emails land in the primary inbox, not spam) is arguably the most important metric. Poor deliverability means your carefully crafted emails never get seen.
- MailerLite: Consistently high deliverability (98%+). They use dedicated IP pools and enforce good sender practices. Independent tests show MailerLite often beats larger competitors.
- ConvertKit (Kit): Excellent deliverability (99%+). Built specifically for creators, ConvertKit prioritises inbox placement and has strong relationships with ISPs. Many bloggers report the highest open rates with ConvertKit.
- Mailchimp: Good deliverability (97%+) but has had occasional issues with spam folder placement due to their massive shared IP pools. Smaller senders sometimes get caught in filters.
Winner for deliverability: ConvertKit. It's known for the best inbox placement among creator-focused platforms. MailerLite is a close second. Mailchimp is acceptable but less consistent.
Landing Pages & Forms: Capturing Subscribers
Your ability to capture emails depends on form and landing page tools.
- MailerLite: Offers pop-ups, embedded forms, and full landing pages (unlimited on free tier). The drag-and-drop builder is intuitive. You can also host a simple website.
- ConvertKit (Kit): Provides inline forms, modal pop-ups, and landing pages (limited on free). The forms are clean but less customisable than MailerLite. However, they convert well because of their simplicity.
- Mailchimp: Forms and landing pages are available but less flexible. The free tier includes one landing page. Mailchimp's form builder is outdated compared to competitors.
Winner for forms & landing pages: MailerLite. It offers the most features, unlimited landing pages, and better design customisation — all on the free plan.
Affiliate Marketing & Monetisation Features
Bloggers often use their email list to promote affiliate offers or sell their own products. Here's how each platform supports monetisation:
- MailerLite: No native affiliate management, but you can add affiliate links freely. No restrictions on promoting affiliate offers. Supports digital product sales via Stripe integration.
- ConvertKit (Kit): Has a built-in "Commerce" feature to sell digital products and subscriptions directly. Also offers "Recommendations" (a native affiliate network where creators recommend each other's products). Very monetisation-friendly.
- Mailchimp: Native e-commerce features (product recommendations, abandoned cart) but no specific affiliate tools. Mailchimp's terms allow affiliate marketing, but their compliance team can be strict with certain verticals.
If you plan to sell digital products or build a paid newsletter, ConvertKit has the most integrated monetisation features. MailerLite is fine for basic affiliate promotion. Mailchimp is more suited to traditional e-commerce.
Which platform generates the highest email ROI?
Based on industry benchmarks (2026), ConvertKit users report an average of $0.50–$2.00 per subscriber per month from product sales and affiliate income. MailerLite users average $0.30–$1.50. Mailchimp users (on similar lists) average $0.20–$1.00. ConvertKit's superior segmentation and automation lead to higher conversion rates, partially offsetting its higher cost.

ROI Comparison: Net Value at Different List Sizes
Let's model net monthly value (revenue from email minus platform cost) for a blogger with a 5% affiliate conversion rate, average order value $50, and 2% monthly email-driven sales rate. We'll assume $0.50 revenue per subscriber per month from affiliate/product sales (conservative). This is illustrative — your results will vary.
| List size | MailerLite (net monthly value) | ConvertKit (net monthly value) | Mailchimp (net monthly value) |
|---|---|---|---|
| 1,000 subs | Revenue $500 – $0 = $500 net | Revenue $500 – $29 = $471 net | Revenue $500 – $13 = $487 net |
| 5,000 subs | Revenue $2,500 – $30 = $2,470 net | Revenue $2,500 – $59 = $2,441 net | Revenue $2,500 – $45 = $2,455 net |
| 10,000 subs | Revenue $5,000 – $55 = $4,945 net | Revenue $5,000 – $99 = $4,901 net | Revenue $5,000 – $80 = $4,920 net |
| 25,000 subs | Revenue $12,500 – $120 = $12,380 net | Revenue $12,500 – $199 = $12,301 net | Revenue $12,500 – $175 = $12,325 net |
Key takeaway: At all list sizes, MailerLite delivers the highest net value because of its lower cost. However, if ConvertKit's better segmentation and automation increase your revenue per subscriber by even 5% (to $0.525), then ConvertKit would produce $13,125 revenue – $199 = $12,926 net, beating MailerLite. For high-earning bloggers, ConvertKit's superior tools may justify the price. For most bloggers starting out, MailerLite is the smarter financial choice.
When does ConvertKit become worth the extra cost?
If your email-driven revenue per subscriber exceeds $0.70/month, ConvertKit's advanced automation and tagging can lift that further. For bloggers selling digital products ($50–$200 price points) or running paid newsletters, ConvertKit's built-in commerce and lower transaction fees (compared to third-party tools) make it highly competitive. MailerLite is best for bloggers focused on affiliate and ad revenue where complex automation isn't critical.
Pros & Cons of Each Platform
MailerLite
- Pros: Most generous free tier (1,000 subs), cheapest paid plans, unlimited landing pages, intuitive interface, good deliverability, website builder included.
- Cons: Less advanced automation than ConvertKit, smaller integration ecosystem, less robust affiliate/recommendation features.
ConvertKit (Kit)
- Pros: Best deliverability, visual automation builder, powerful tagging and segmentation, built-in commerce and subscriptions, native affiliate network (Recommendations), creator-focused.
- Cons: Expensive at all tiers, very limited free tier (300 subs), forms and landing pages are less customisable.
Mailchimp
- Pros: Strong brand recognition, advanced segmentation on paid plans, good integrations, all-in-one marketing platform.
- Cons: Pricing has become expensive, deliverability less consistent, free tier very restrictive, interface can be bloated.
Which Platform Wins for Different Blogger Types?
- For beginner bloggers on a tight budget: MailerLite is the clear winner. The free tier supports up to 1,000 subscribers and includes automation and landing pages. You can stay free for a long time while you build your list.
- For creators selling digital products or paid newsletters: ConvertKit (Kit) is best. Its built-in commerce, tagging, and automation are purpose-built for monetising an audience. The higher cost is offset by higher conversion rates.
- For bloggers focused solely on affiliate marketing and display ads: MailerLite again wins on cost. You don't need ConvertKit's advanced commerce features. MailerLite's automation is sufficient for basic welcome sequences and broadcast emails.
- For bloggers who already use Mailchimp for other marketing (e.g., e-commerce): Stick with Mailchimp if you're deeply integrated. But for most bloggers, Mailchimp is now overpriced and less specialised.
- For hybrid blog + email list builders: Consider combining MailerLite with a self-hosted blog (WordPress). For a deeper look at platforms, read Best Blogging Platforms in 2026.
Migration & Portability: Can You Leave?
Lock-in is a real concern. All three platforms allow you to export your subscribers (CSV) and some data. MailerLite and ConvertKit make it relatively easy to migrate out. Mailchimp's export is also straightforward. However, migrating automation workflows and tagging structures is manual regardless of platform. If you think you might outgrow your email tool, MailerLite and ConvertKit both have good import/export tools. Avoid proprietary lock-in by keeping a backup of your subscriber list separately.
