ConvertKit vs Beehiiv: could you build either?

Why ConvertKit gets Borderline
- Subscriber lists with tags and a simple broadcast composer share Mailchimp's buildable core
- Landing pages for lead capture are standard static-page-plus-form work
- For a creator sending occasional newsletters with no automation, this is a real weekend build
Why Beehiiv gets Borderline
- The writing and sending core is the same buildable pattern as any newsletter tool — a composer and a transactional email API
- Stripe Subscriptions gating paid-only posts is well-documented
- A public archive of free posts is ordinary content rendering

What you lose leaving ConvertKit
- Visual sequence/automation builders (branching email flows triggered by subscriber behavior) are a small workflow engine, the same challenge every email tool on this register faces once automation enters the picture
- Deliverability at scale is the same ongoing reputation problem as every sender on this list
- Their creator-focused features (paid newsletters, digital product sales) layer real payment and access-control work on top
What you lose leaving Beehiiv
- Referral/reward programs (subscribers earn perks for referring others) need real tracking and fraud-resistance logic
- Their built-in ad network placement is a marketplace feature, not a writing-tool feature
- Deliverability at scale is the same ongoing reputation problem every email sender on this register shares

Questions
Is ConvertKit or Beehiiv easier to build yourself?
These land in the same place — both borderline. Both are a weekend of work. Beehiiv lists at $42/mo against $25/mo for ConvertKit, a difference of $204 a year.
Can I build ConvertKit?
Borderline. ConvertKit's core is the same buildable email-and-list pattern as Mailchimp, just positioned for creators instead of businesses. The visual automation builder (if a subscriber does X, wait, then do Y) is the part that takes real work to match.
Can I build Beehiiv?
Borderline. Shares Substack's exact shape: writing and sending posts is genuinely buildable. Beehiiv adds real growth tooling — referral programs, ad network placement — on top, which is a second, separate product.
What do ConvertKit and Beehiiv have in common technically?
Both rebuilds need landing page, crud database, email notifications. That shared foundation is why they score similarly on the parts they overlap on — the difference comes from what each one adds on top.
