3. Mailchimp: Best For Small Businesses Starting Out
If you’re just getting started with email marketing and want something simple, affordable, and easy to navigate, Mailchimp is one of the most beginner-friendly platforms out there.
It's been around for years, and there's a reason it's still widely used. Mailchimp makes it easy to design emails, manage your list, and send your first campaign without needing any prior experience. And with a generous free plan, it’s a practical choice for small businesses and solo entrepreneurs testing the waters.
That said, while it’s great for early-stage users, it may not scale well for creators who want advanced automations or tight integration with online courses and digital products.
Key Features
Here’s what makes Mailchimp a solid option for beginners:
- User-friendly editor: Mailchimp’s drag-and-drop builder is straightforward and intuitive. You can create polished, branded emails without any technical skills.
- Marketing CRM: Keep track of your contacts with basic customer profiles, tags, and segments to help you organize and personalize your campaigns.
- Automation workflows: Set up simple automations like welcome emails or post-purchase follow-ups triggered by subscriber behavior.
- A/B testing: Improve your campaigns by testing different subject lines, images, or content layouts to see what resonates best with your audience.
- Basic landing pages: Create simple signup forms and landing pages to grow your email list, even if you don’t have a website yet.
Pricing
- Free plan (Up to 500 contacts, 1,000 monthly email sends, basic email templates, and limited support)
- Standard plan starting at $10 /mo for 12 months. Then, starts at $20 /month
- Premium plan starting at $175 /mo for 12 months. Then, starts at $350 /month
Ideal For
Mailchimp is ideal for small businesses, solopreneurs, and side hustlers just getting started with email marketing. If you’re looking for a low-cost, low-barrier entry point, it’s one of the easiest platforms to learn.
It works best when your email needs are simple, like sending newsletters, updates, or promotions to a small list.
But as your business grows and you start selling digital products, hosting online courses, or using advanced automations, you might find Mailchimp's limitations get in the way. Many knowledge entrepreneurs eventually graduate to platforms with deeper integration and more powerful features.
4. ConvertKit: Best For Content Creators
While other platforms try to be everything at once, ConvertKit, now known as Kit, stays focused on helping creators grow their audience and connect through email. It’s not overloaded with features you don’t need — just clean, effective tools to build relationships and drive engagement.
From easy list-building to visual automation and subscriber tagging, ConvertKit offers a creator-friendly experience that keeps things simple, without sacrificing power where it counts.
Key Features
Here’s what makes Kit stand out for content-focused entrepreneurs:
- Visual automation builder: Map out your entire email funnel using a drag-and-drop editor. It’s intuitive and makes it easy to see exactly how your subscribers move through your sequence.
- Creator-focused templates: ConvertKit’s email templates are minimal and content-first, helping your words take center stage. Perfect for creators who care more about clarity than heavy visuals.
- Tag-based subscriber system: Instead of managing multiple lists, Kit uses tags to organize your subscribers based on their behavior, interests, or actions — giving you more flexibility in how you target your messages.
- Landing page builder: No website? No problem. You can build simple, stylish opt-in pages to start growing your email list right away.
- Paid newsletter option: Want to charge for your content? Kit includes basic monetization features so you can sell access to premium newsletters without needing a third-party platform.
Pricing
Kit offers straightforward pricing with room to grow:
- Free Plan: For up to 1,000 subscribers
- Creator Plan: Starts at $25/month
- Creator Pro Plan: Starts at $50/month
Higher-tier plans unlock more advanced automation, integrations, and access to premium support.
Ideal For
Kit is a great fit for:
- Bloggers and writers building an audience
- Podcasters and video creators promoting new content
- Solo entrepreneurs offering free or paid resources via email
It’s ideal if you want a focused email tool that’s not bloated with features you’ll never use. You’ll get all the core marketing tools you need to grow, engage, and monetize your list — in a clean, streamlined interface.
That said, Kit is not a full business platform. If you plan to launch courses, host memberships, or build a digital product ecosystem, you’ll likely need to connect it with other tools for those features.
