What it is

The plain signup: an email field and a thank-you. Shown once a week per visitor, from the corner, not over the page.

When to use it

• You publish regularly and the list itself is the product.
• Your brand voice can carry the ask without a discount.
• You want a low-key presence on content pages.

Why it works

Modesty scales: a slide-in that asks once a week keeps the option open without training visitors to close pop-ups on sight.
