My Personal Choice and Why

After testing all three platforms extensively across multiple blogs, I personally use ConvertKit for my main content-focused blogs and MailerLite for smaller niche sites and client projects.

Why ConvertKit for my main blogs? The tag-based system aligns perfectly with how I organize content, the automation is intuitive yet powerful, and the built-in monetization features have directly increased my revenue. The slightly higher cost is offset by better performance and time saved.

Why MailerLite for smaller projects? The free plan is genuinely useful (unlike many competitors), and the balance of features to cost is unbeatable for blogs that are still finding their footing.

Final Recommendations: Making Your Decision

Choose ConvertKit if:

• You’re primarily a content creator (writer, blogger, podcaster)
• You value simplicity and effectiveness over design flexibility
• You plan to monetize your email list directly
• You prefer a tag-based organization system
• You don’t mind paying slightly more for a creator-focused platform

Choose MailerLite if:

• You’re on a tight budget but need essential features
• You want a balance of usability and design flexibility
• You’re just starting out and need room to grow affordably
• You prefer a clean, modern interface
• You want automation capabilities even on a free plan

Choose MailChimp if:

• You need advanced design capabilities for visual content
• You plan to scale beyond blogging to a larger business
• You require the most extensive integration options
• You value advanced analytics and reporting
• You’re willing to navigate a steeper learning curve for more features

The Bottom Line: Start Now, Choose Wisely

The most important takeaway from my years of testing these platforms is simple: the best email marketing platform is the one you’ll actually use to start building your list today.

For most bloggers on a budget, I recommend starting with MailerLite’s free plan, which gives you all the essential tools to begin building your email marketing strategy without any financial pressure.

As your blog grows and your needs evolve, you can always migrate to ConvertKit or MailChimp—but don’t let platform indecision prevent you from starting your email list today. That was my costly mistake, and I hope this comparison helps you avoid it.
