What Kit (ConvertKit) Really Costs
The subscription is only 3% of what ConvertKit actually costs your team. Here's the full picture.
Total Cost of Ownership
A 1-person team at ConvertKit's published rate of $29/seat/month. The subscription is 3% of the real cost.
Subscription cost
$29/seat x 1 seats x 12 months
$348/yr
Labor cost
15 hrs/month x $50/hr loaded rate x 12 months
$9,000/yr
Error & rework cost
$100/month x 12 months
$1,200/yr
Total Cost of Ownership
$10,548/yr
Labor rate based on BLS ECEC June 2025 ($45.65/hr private industry total compensation, rounded to $50). Your actual numbers depend on team size, role mix, and usage. Run it with your own data.
What the invoice doesn't show
Kit's Newsletter plan (free) supports up to 10,000 subscribers but blocks visual automations, sequences, and third-party integrations. The features that make email marketing effective require Creator ($29/mo) or Creator Pro ($59/mo).
Pricing scales steeply with subscriber count. At 25,000 subscribers, Creator costs $66/mo and Creator Pro costs $111/mo. At 55,000 subscribers, Creator Pro hits $227/mo — approaching enterprise tool pricing for what remains a creator-focused platform.
Kit lacks built-in A/B testing for email content (only subject lines). There's no send-time optimization, no multivariate testing, and limited segmentation compared to marketing automation platforms at similar price points.
Kit's visual automation builder, while praised for simplicity, can't handle complex conditional logic. Users report needing to build workarounds with tags and segments for workflows that tools like ActiveCampaign handle natively.
Why this category is changing
Kit (formerly ConvertKit) built its brand serving creators before 'creator economy' was a term, but the rebrand to 'Kit' signals identity confusion. The platform is too expensive for hobbyist creators (Beehiiv and Substack are free or cheaper), too limited for serious businesses (no A/B testing, weak analytics), and its pricing scales into territory where buyers expect enterprise features they won't find. The creator market Kit pioneered has been commoditized.
Beehiiv
Free (2.5K subs), $49/mo (Scale), $99/mo (Max)
Newsletter platform built for growth with AI writing tools, built-in referral program, and ad network for monetization. Free plan includes unlimited sends and up to 2,500 subscribers. Designed for the creator economy Kit pioneered.
MailerLite
Free (1K subs), $10/mo (Growing), $20/mo (Advanced)
Full visual automation on paid plans starting at $10/mo vs Kit's $29/mo. AI writing assistant, A/B testing (not just subject lines), and send-time optimization included. More features at a lower price point.
Buttondown
Free (100 subs), $9/mo (Basic), $29/mo (Professional)
Minimalist newsletter tool for writers who want clean design without bloat. Markdown-native editor, built-in analytics, and paid subscription support. Free for up to 100 subscribers.

How we calculate TCO
Total Cost of Ownership includes subscription fees, labor (valued at $50/hr based on BLS ECEC data), and estimated error costs. Error cost is inherently speculative and can be set to $0 for a conservative estimate. All defaults are sourced from published benchmarks and adjustable in our methodology.
