ConvertKit vs Brevo: Which Email Platform Fits You Best in 2025

Choosing between marketing tools isn’t about picking the “coolest” one — it’s about choosing the tool that best fits your needs, your scale, and your approach. In this comparison, we explore ConvertKit (also known as Kit) and Brevo (formerly Sendinblue) objectively. We’ll see where each shines, where each has limitations, and which kind of user fits which tool best.

1. What Are ConvertKit and Brevo?

ConvertKit (Kit)

ConvertKit, now often branded as Kit, is an email-first platform built especially for creators — bloggers, authors, online educators. It focuses on simplicity, sequences, segmentation, and creator monetization.

Some core strengths:

• Simple, easy-to-use interface for non-technical users.
• Strong email sequences and funnel automation with templates for creators.
• Tools for selling digital products and subscriptions.

But it is more narrowly focused — mainly email, forms, and sequences — not a full marketing suite.

Brevo

Brevo positions itself as an all-in-one marketing platform, combining email campaigns, automation, SMS & WhatsApp, CRM, transactional emails, landing pages, and more.

Some highlights:

• You can run multiple channels (email + SMS) from one place.
• It supports advanced automation, contact management, and segmentation.
• Pricing is based on volume of sends (not just number of contacts) in many plans.
• Strong deliverability metrics in independent comparisons.

Brevo aims to be a broader system, not just email.

2. Feature Comparison

Here’s a side-by-side view of key features to help you see where each tool is stronger or more limited:

Feature	ConvertKit (Kit)	Brevo
Ease of Use	Very beginner-friendly, especially for creators.	Also user-friendly, though with more features to navigate.
Automation / Sequences	Strong sequence builder, templates for creators, triggers and conditions.	Advanced visual automation, multiple triggers, cross-channel workflows.
Multi-Channel Support	Primarily email, forms, landing pages, and creator monetization.	Email, SMS, WhatsApp, CRM, transactional emails — more channels built in.
Pricing Model	Charges largely based on number of subscribers/contact tiers, often with unlimited sends in many plans.	Many plans charge based on email sending volumes (unlimited contacts).
Deliverability	Good, especially with lean email infrastructure. But comparisons show Brevo has a slight edge in some tests.	Excellent in deliverability tests, often outperforming ConvertKit in inbox placement.
Integrations & Extensions	Good integration ecosystem for creators (e.g. e-course, membership tools).	Broader integration with marketing, CRM, web tools, APIs.
Best Use Cases	Solo creators, authors, small digital product businesses	Small-medium businesses that want multi-channel marketing under one roof

3. Where ConvertKit Does Better

ConvertKit’s strengths tend to be in areas that appeal to creators and minimalistic marketing:

• Simplicity and clarity: Many users praise its clean, creator-focused UI.
• Strong sequence and automation templates tailored to creators (launch sequences, evergreen flows).
• Built-in monetization / paid newsletter support — you can sell digital products or subscriptions directly.

If you're primarily emailing a community or audience, producing content, and selling small digital products, ConvertKit offers a leaner, more focused experience.

4. Where Brevo Has the Edge

Brevo shines especially when your needs grow beyond just email:

• Multi-channel marketing: Because Brevo supports SMS, WhatsApp, and CRM, you can manage multiple communication paths from one dashboard.
• Cost structure: For many growing lists, paying for email volume (rather than number of contacts) can be more efficient.
• Stronger deliverability in tests: Independent deliverability comparisons often show Brevo outperforming ConvertKit in inbox placement.
• Wider integrations & tooling: More flexibility to connect with other platforms and build complex systems.
• Advanced automations & workflows: More branching conditions, cross-channel triggers, and robust logic.

If your business needs to grow with additional channels, segmentation, and advanced flows — Brevo offers more scalability.

5. Which One to Use — Based on Your Situation

Here’s a quick decision guide:

Your Situation	Better Pick	Reason
You’re a creator, blogger, or small digital product seller	ConvertKit	It’s optimized for content creators, simplicity, and monetization in one tool.
You need email + SMS + multi-channel marketing	Brevo	It gives you more communication channels under one roof.
You have a large list and moderate sending frequency	Brevo	Charging per send (not per contact) can save you money at scale.
You prefer minimal tools and lightweight setups	ConvertKit	Easier UI and less complexity.
You plan to scale marketing, automation, and CRM together	Brevo	More built-in features make scaling easier without swapping platforms.

6. Final Thoughts & Recommendation

Neither tool is “bad” — both have strong value.

If your primary focus is content, newsletters, and growing a creator business — ConvertKit is lean and built for that.

But if you want to grow into a more complex marketing structure — more channels, more data, more automation — Brevo often gives you more room to expand.

In my practice at RenoEasy, I often start creators on ConvertKit-style simplicity, but when they hit limits, they transition to Brevo’s wider capabilities.
