Take on Kit (ConvertKit)
Kit's strength is the creator workflow: tags-as-segments, visual automations, simple commerce. The weakness is growth — Beehiiv's recommendation network and boost ecosystem are doing what Kit hasn't matched. If you're growing, Beehiiv. If you're monetizing an established list, Kit.
Contender A
Kit (ConvertKit)
Creator-first email (rebranded from ConvertKit to Kit) with tag-based subscribers.
- Newsletter writers, course creators, and coaches who need automations, not blasts.
- Free up to 10,000 subscribers. Creator from $15/mo, Creator Pro from $29/mo.
Best for
Pricing
Pros
- Generous 10k free tier — best in the category
- Tag-and-segment model fits content businesses better than lists
- Built-in landing pages, paid newsletters, and tip jars
Trade-offs
- Default templates are deliberately plain text — not ecommerce-friendly
- Visual automation builder is powerful but has a learning curve
Contender B
Customer.io
Event-driven messaging for product-led teams — the technical upgrade from ActiveCampaign.
- SaaS and product teams that want behavior-triggered email, SMS, and push driven by their own data.
- Essentials from $100/mo for 5,000 profiles. Premium from $1,000/mo for larger volumes.
Best for
Pricing
Pros
- Real event-based triggers — react to anything your product sends
- Best-in-class workspaces, branching, and A/B logic
- Email + push + SMS + in-app in one workflow
Trade-offs
- Starts at $100/mo — not for hobby projects
- Requires developer setup to send events; not a drag-and-drop marketer tool
