Quick Verdict: ConvertKit (now "Kit") is the best email platform for bloggers, authors, course creators, and newsletter publishers who want to build an audience and monetize it. Its tag-based system and free plan (up to 10K subs) are creator-first. But it's expensive at scale and has no SMS or multi-channel support. Rating: 4.3 / 5

2. Pricing
ConvertKit offers a generous free plan: up to 10K subscribers at no cost. However, the free plan has limited features (no advanced automation, no email support). Paid plans scale by subscriber count:
- Free: Up to 10K subs, 1 broadcast sequence, basic reporting
- Creator ($9/mo): Up to 300 subs, unlimited sequences, email support
- Creator Pro ($50/mo): Up to 1K subs, advanced automation, subscriber scoring
At 5,000 subscribers: $50/mo on Creator Pro. More expensive than Brevo ($25/mo) but cheaper than Mailchimp ($100/mo).
3. Tag-Based Architecture
ConvertKit uses tags and segments instead of folders/lists. A subscriber can have multiple tags (e.g., "free-download", "purchased-course", "opens-daily"). You can trigger automations based on tags, send targeted content, and build complex segments. This is far more flexible than Mailchimp's rigid audience/list system and is the main reason creators prefer ConvertKit.
