Newsletter Signup
A newsletter signup with a checkable promise: three lines on what the letter contains, the cadence and the subscriber count beside the field.
React + Tailwind, shadcn-compatible: press “Copy for AI” and your Cursor or Claude Code agent installs it with the shadcn CLI.
What you can change
- the bullets array — the newsletter promise
- title, description and eyebrow
- proof, frequency and errorText
Built from
- Action Buttonbutton-001
- Checkbox Rowcheckbox-001
- Section headingheading-001
- Floating Label Inputinput-001
The install command brings these components too. The block only passes them props: their palette and behaviour stay their own.
A link for your AI agent: preview, code and instructions.

FAQ
- How do I add Newsletter Signup with Cursor or Claude Code?
- Press “Copy for AI” on this page and paste it into your agent's chat. The instruction contains the shadcn CLI install command, the dependencies and what to keep, so the agent installs this exact component instead of recreating a lookalike.
- What does Newsletter Signup depend on?
- No npm packages beyond React and Tailwind CSS. It also installs catalog components: button-001, checkbox-001, heading-001, input-001.
- What can I change in Newsletter Signup?
- Adapt: the bullets array — the newsletter promise; title, description and eyebrow; proof, frequency and errorText. Keep as installed: the button-001, checkbox-001, heading-001, input-001 imports from @/components/vibeui/ — do not inline their code into the block or swap in your own; the parts receive props only; the local --vibeui-blog-004-* palette — do not swap it for your theme tokens; :user-invalid instead of :invalid — an untouched field must not turn red.
- Is Newsletter Signup free?
- Yes. The preview is open without an account; with a free account you can copy up to 20 components a month.

Technical notes
A composite block: imports button-001, checkbox-001, heading-001, input-001 from @/components/vibeui/ — the install command brings them along with the block. The block owns the layout and its own text, passes the parts props only and leaves their --vibeui-<name>-* palettes alone. The block is self-contained: one file, no npm dependencies, its own palette in local variables --vibeui-blog-004-*. A server component: the validation is native — type="email" and required, and the error is shown by :user-invalid rather than :invalid. The error text is always present in the markup but visually hidden with clip-path, and is tied to the field through aria-describedby. The dark ground is the block's own, so the block reads both on a light page and on a dark catalogue card. Submission is implemented by the calling code.
