Agent-first, human-friendly email ops in two operating models. SendyKit wraps around Sendy without modifying core, giving humans and agents a modern API, CLI, analytics, AI, health diagnostics, and managed email operations.
The fastest way to pick the right SendyKit path is to decide what matters more: ownership, managed operations, or high-leverage automation with predictable economics.
You already trust your own infrastructure, want a perpetual license, and prefer your Sendy install to stay on your domain under your control.
You want SendyKit to feel like a standalone app while updates, billing, hosted control-plane work, and managed infrastructure stay off your plate.
If API budget, connected-site headroom, AI allowance, and machine-payment economics matter more than hosting ideology, use the plan family that keeps those margins healthy.
The difference is who runs the stack. Not whether you get the real product.
The super-exoskeleton for Sendy. For operators who want SendyKit wrapped around their own Sendy install, on their own infrastructure, with permanent ownership and a selectable future-major entitlement.
Agent-first, human-friendly email ops as a standalone-feeling SendyKit app at app.sendykit.dev, without running the stack yourself.
Starter maps to Self-Hosted Standard features. Growth, Scale, and Enterprise map to Pro-level capability. Self-hosted pricing varies by included future major upgrades; SaaS adds managed operations on top.
Self-hosted pricing is not four random prices. It is one ownership decision with four different levels of future-major headroom.
Lowest launch entry. Best when you want SendyKit now and expect to re-evaluate later rather than pre-buy a long roadmap.
The likely default. Enough future-major cushion to feel smart later without jumping all the way to prestige territory.
For buyers who already know SendyKit will be a durable operating layer and want a deeper hedge against future upgrade cost.
Dramatically premium on purpose. The anti-default tier for buyers who want all future major upgrades included and do not want to think about the ladder again.
Pricing and limits below track the current product truth: paid-only SaaS, connected-site caps, and plan parity.

* Self-hosted email throughput depends on your SES or SMTP provider quota, not an artificial SendyKit cap. Self-hosted launch tiers are Current + 1 / +3 / +5 / Sovereign Infinite; only Sovereign Infinite stays constant after launch.
1-site edition with Current + 1 / +3 / +5 / Sovereign Infinite launch tiers.
3-site edition with the same launch ladder plus AI, automations, and higher-tier operator power.
Standard-equivalent capability with a managed stack and one connected WordPress site.
Pro-level capability, better machine-payment economics, more API budget, and more connected-site headroom.
Yes. SaaS follows feature parity by tier: Starter maps to Self-Hosted Standard, and Growth/Scale/Enterprise map to Pro-level capability. SaaS adds managed infrastructure, billing, and connected-site controls on top.
Choose self-hosted if you want to own the stack, run on your own Sendy install, and keep everything on your own server. Choose SaaS if you want the SendyKit operator experience without handling hosting, updates, SMTP infrastructure, or remote site management.
Not as a customer-managed dependency. SaaS is sold as SendyKit Cloud at app.sendykit.dev. Backend Sendy-compatible mechanics stay behind the SendyKit shell, so the operator experiences a standalone SendyKit app.
Because remote WordPress installs cost real support, security, heartbeat, and API budget. Starter includes 1 connected site, Growth 5, Scale 20. That keeps margins healthy without stripping product capability.
SendyKit shows usage bars and warning badges before you hit the cap. Critical subscriber flows stay protected first; the system warns you well before you need to upgrade.
Yes. The product surface stays familiar. The operating model changes: self-hosted gives you ownership, SaaS gives you managed operations. Both keep the same SendyKit design language and core feature set.
Self-hosted is for Sendy operators who want ownership. SaaS is for teams who want the SendyKit cockpit without running the engine room. Both get the same product philosophy and the same core power.
