Gerador de inscrição em newsletter com IA.

Create a centered newsletter signup section with generous vertical padding: a headline naming the topic and the cadence, one supporting line describing exactly what arrives and how often, then an inline form with a single email input and a Subscribe button sitting flush beside it on desktop and stacked full-width on mobile. Use type="email", autocomplete="email", inputmode="email" and a visually hidden label. Validate on blur and on submit rather than on every keystroke, showing the message in an element referenced by aria-describedby with aria-invalid on the field. Disable the button and swap its label to a spinner while submitting, then replace the whole form with a confirmation message asking the reader to check their inbox.

Create a compact inline newsletter strip for placement mid-article: a tinted rounded panel about the width of the article column, with a one-line bold prompt referencing the topic of the surrounding post, a short second line naming the cadence, and a single-row form with an email input and a short button label. No heading larger than the article body headings, so it does not read as a new section. Validate inline on blur with the error text replacing the cadence line rather than growing the panel, keep the panel height fixed across default, error and success states, and on success swap the form for a one-line confirmation in place.

Create a two-column newsletter signup panel: on the left, a headline, three short bullet points naming what each issue contains, the email form and a muted no-spam line; on the right, a framed screenshot or rendered preview of a recent issue with a link to read it in full before subscribing. Give the right column a fixed aspect-ratio box so the panel does not reflow while the preview image loads. Keep the form to one input plus a button, with inline validation on blur and an aria-live region for the result. Stack to one column on mobile with the preview below the form, and lazy load the preview image.

Create a lead-magnet signup section: a thumbnail of the asset on the left, and on the right a headline naming the asset concretely, a line stating its format and length, an email input with a Send it to me button, and a small line stating that subscribers also receive the weekly email so the ongoing commitment is not a surprise. Add a required consent checkbox with the wording as a visible label rather than a tooltip, and block submission with an inline message if it is unchecked. On success, show a confirmation that names the sending address and asks the reader to confirm the double opt-in email before the download link arrives.

Create a newsletter signup section led by social proof: a stacked row of five overlapping reader avatars with a plus-N chip, then a line stating the subscriber count and who they are, then the headline, then the form. Below the button, a two-item reassurance row covering unsubscribe in one click and no sharing of addresses. Keep the form to one email field with inline validation on blur, aria-invalid on the field and the message wired via aria-describedby. Give the avatars explicit width and height so the row does not shift as images load, and render a confirmation state in place of the form on success rather than a toast.

Create a slim newsletter capture bar fixed to the bottom of the viewport, revealed once the reader passes about 60% scroll depth and animated in with a short translate. It holds one line of copy, an email input, a short button and a labelled dismiss button. Persist the dismissal in localStorage so it never returns for that reader, and hide it entirely for anyone already subscribed. Show validation errors as a tooltip above the input rather than growing the bar, keep the bar under 72px tall, add bottom padding to the page so it never covers the final content, respect prefers-reduced-motion, and collapse to a single tap target that expands into the form on mobile.
