Is there a double opt-in or confirmation email?

No. Subscribing is immediate, so make your card copy clear about what people are signing up for. Because there is no confirmation step, the experience stays fast and friction-free.

Can I use more than one signup card?

Yes. Create as many cards as you like, each with its own design and slug for different sites or campaigns. They all feed the same tenant-wide list, so subscribers are never split by which card they used.

How do I add subscribers from my own backend?

Use the server-to-server subscribe API with a secret key. It is ideal for checkout flows, gated downloads, or imports. The endpoint supports idempotency to prevent accidental duplicates.

Can I export my subscribers?

Yes. Export the full list as a CSV at any time, including each subscriber's email, name, status, source, and sign-up date. You can also read the list programmatically through the API.

Will the widget only load on my own website?

Yes. Each public key is locked to the domains you register, and requests are rate-limited per key, so the card only works where you have authorized it.

How it works

Live in a few steps

Design a card

Create a card, write the heading, button, and thank-you copy, add an optional name field, and style the colours, theme, font, and corners with a live preview.

Publish it

Save and publish the card. Only published cards can be embedded, so you can keep designing in draft until it is ready.

Embed the widget

On the Developer page, create a public key locked to your domains, then copy the one-line script tag and drop it into any page.

Subscribers roll in

Visitors subscribe instantly with no confirmation email. Each sign-up joins your tenant-wide list, raises a notification, and fires a webhook if you have one registered.

Manage and export

Search, filter, unsubscribe, or delete subscribers from the dashboard, and export the whole list as CSV to send campaigns through your own email tool.

Where it shines

Made for real work

Grow your blog audience

Design a get-new-articles card, embed it in your blog footer, and collect readers into one list you can email whenever you publish.

Capture leads on your marketing site

Add a branded signup card to landing pages and your homepage; each card matches its page while feeding the same central list.

Collect subscribers at checkout or download

Use the server-to-server subscribe API to add a customer during a checkout flow, a gated download, or an import, without showing a card.

Consolidate scattered sign-up forms

Replace a patchwork of per-site forms and spreadsheets with one workspace-wide list, tagged by source, that you can search and export.
