The verdict
Which one should you pick?
Ghost
Pick it for
- A film or documentary team running a paid behind-the-scenes or case-study newsletter on its own domain
- A freelance editor or DP selling a paid tier of tutorials, LUTs or breakdowns
- Agencies or production companies that want a branded site, newsletter and member list in one system
Stands out
- Open source under MIT: you can self-host the full platform for free, or move your site off Ghost(Pro) without losing the content model.
- No revenue share on memberships: Ghost(Pro) paid plans charge 0% on member payments (Stripe fees still apply).
Watch out
- Email sequences and sequence analytics are still in beta and only cover welcome flows
- No free hosted plan, and Starter has no custom themes or native advanced analytics
Kit (ConvertKit)
Pick it for
- Building a mailing list for a short film, festival run or documentary before release
- Running a launch sequence for a crowdfunding campaign or a course on filmmaking
- Selling LUT packs, presets, scripts or project files as digital downloads
Stands out
- Creator-first pricing: the free tier covers up to 10,000 subscribers with unlimited landing pages, forms and broadcasts, which is more generous than a paid-only newsletter tool.
- Visual Automations on every paid plan (Creator and up) make multi-step sequences triggered by tags, purchases or link clicks buildable without code.
Watch out
- Price scales with subscriber count: Creator is $33/mo at 1,000 subscribers and rises as the list grows.
- Automations and sequences are locked on the Free plan, and Kit branding stays on emails until Creator.
Substack
Pick it for
- Film critics and festival reporters with a paying readership
- Production-diary writers who sell behind-the-scenes posts to paid readers
- Doc filmmakers and podcast hosts pairing a written newsletter with audio and video episodes
Stands out
- Built-in paid subscriptions and email delivery: no separate newsletter tool, payment setup or landing page needed
- Free to publish, with no monthly software fee; Substack's cut is 10% of paid revenue plus Stripe fees, so cost scales with income
Watch out
- 10% fee plus Stripe fees: third-party estimates put the combined take at 13 to 16% of gross
- Little control over layout, automation or email sequences compared with Ghost or Kit
