Collect subscribers with a customizable popup, a sidebar signup card, and a header menu button, then compose and send newsletters to your list directly from your dashboard. No third-party account required. Everything is controlled from a single settings screen, and the popup can be styled independently for desktop and mobile. **Capture subscribers three ways** * A responsive popup with delay, scroll-depth, or exit-intent triggers. * A sidebar signup card you can drop into any widget area or place with a shortcode. * A subscribe button that injects into a theme menu location or appears via shortcode. **Design control** * Separate desktop and mobile colors, image, shape, dimensions, and animations. * Six popup layouts (split, stacked, minimal, circle, hexagon, octagon). * Ten entrance animations plus badge and screen-transition effects. * Live in-dashboard preview at desktop and mobile viewport sizes. **Built-in sending** * Compose newsletters with the standard WordPress editor. * Save drafts, schedule for later, or send immediately. * Batched delivery through your site’s normal `wp_mail()` pipeline. * Automatic, one-click unsubscribe link on every email. * Customizable from-name, from-address, and email design. **Subscriber management** * View your subscriber list in the dashboard. * Export all subscribers to CSV. * Remove subscribers individually. **Shortcodes** * `[letterness_subscribe_button]` places the subscribe button anywhere. * `[letterness_card]` places the signup card anywhere. For large lists or better inbox placement, pairing Letterness with an SMTP plugin( such as WP Mail SMTP) is recommended. ## 屏幕截图 [⌊The newsletter popup on the front end, with the signup form and bonus content.⌉⌊ The newsletter popup on the front end, with the signup form and bonus content.⌉[ The newsletter popup on the front end, with the signup form and bonus content. ## 安装 1. Upload the `letterness` folder to the `/wp-content/plugins/` directory, or install the plugin through the **Plugins > Add New** screen in WordPress. 2. Activate the plugin through the **Plugins** screen. 3. Open **Letterness** in the admin menu to configure triggers, design, content, and sending. 4. (Optional) Add the signup card under **Appearance > Widgets**, or place `[letterness_subscribe_button]`/`[ letterness_card]` anywhere on your site. ## 常见问题 ### Do I need a third-party email service? 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. ### How do visitors unsubscribe? Every email includes a signed, one-click unsubscribe link. The link is verified with a secure token and requires no login. ### Can I show a different design on mobile? Yes. Colors, image, shape, dimensions, and animations each have an optional mobile override, so desktop and mobile can look completely different. ### Where is the popup shown? 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. ### Does it work with block themes? 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. ### What happens to my data when I uninstall? Deleting the plugin removes its options, both custom database tables (subscribers and newsletters), and any scheduled newsletter events. ## 评价 此插件暂无评价。 ## 贡献者及开发者 「Letterness」是开源软件。 以下人员对此插件做出了贡献。 贡献者 * [ kamrankazmi ](https://profiles.wordpress.org/kamrankazmi/) [帮助将「Letterness」翻译成简体中文。](https://translate.wordpress.org/projects/wp-plugins/letterness) ### 对开发感兴趣吗? 您可以[浏览代码](https://plugins.trac.wordpress.org/browser/letterness/)，查看[SVN仓库](https://plugins.svn.wordpress.org/letterness/)， 或通过[RSS](https://plugins.trac.wordpress.org/log/letterness/?limit=100&mode=stop_on_copy&format=rss) 订阅[开发日志](https://plugins.trac.wordpress.org/log/letterness/)。 ## 更新日志 #### 4.0.1 * Enqueued the preview highlight styles and script instead of printing them inline. * Housekeeping and code-quality improvements. #### 4.0.0 * Public release on WordPress.org. * Independent desktop and mobile design for the popup. * Built-in newsletter composer with drafts, scheduling, and batched sending. * Sidebar signup card, header subscribe button, and shortcodes. * Secure token-based one-click unsubscribe. * Subscriber CSV export. ## 额外信息 * 版本 **4.0.1** * 最后更新：**1 周前** * 活跃安装数量 **不到10** * WordPress 版本 ** 6.2 或更高版本 ** * 已测试的最高版本为 **7.0.4** * PHP 版本 ** 7.4 或更高版本 ** * 语言 * [English (US)](https://wordpress.org/plugins/letterness/) * 标签 * [email](https://cn.wordpress.org/plugins/tags/email/)[newsletter](https://cn.wordpress.org/plugins/tags/newsletter/) [Opt-in](https://cn.wordpress.org/plugins/tags/opt-in/)[popup](https://cn.wordpress.org/plugins/tags/popup/) [subscribe](https://cn.wordpress.org/plugins/tags/subscribe/) * [高级视图](https://cn.wordpress.org/plugins/letterness/advanced/) ## 评级 尚未提交反馈。 [您的评价](https://wordpress.org/support/plugin/letterness/reviews/#new-post) [查看全部评论](https://wordpress.org/support/plugin/letterness/reviews/) ## 贡献者 * [ kamrankazmi ](https://profiles.wordpress.org/kamrankazmi/) ## 支持 有话要说吗？是否需要帮助？ [查看支持论坛](https://wordpress.org/support/plugin/letterness/)
