Frequently Asked Questions

Common questions about Letterness

No. Letterness stores subscribers in your own database and sends through WordPress wp_mail(). For higher deliverability on larger lists, an SMTP plugin is recommended.

Every email includes a signed, one-click unsubscribe link. The link is verified with a secure token and requires no login.

Yes. Colors, image, shape, dimensions, and animations each have an optional mobile override, so desktop and mobile can look completely different.

By default the popup can auto-open using a time delay, scroll depth, or exit intent. You can also disable auto-open and only show it when a visitor clicks the subscribe button.

Yes. Use the shortcodes to place the button or card in block themes, or drag the widget into a widget area on classic-widget themes.

Deleting the plugin removes its options, both custom database tables (subscribers and newsletters), and any scheduled newsletter events.
