內容簡介
Newsletter Plugin 是一個很好用的外掛，可用於生成 HTML 電子報，在多種郵件客戶端中呈現效果良好。其高級拖放合成器使您創建好看的電子報輕而易舉。
但是，一般認為還需要包括電子報的 “純文本” 版本。
為 Newsletter plugin 添加 “純文本” 功能，會在 Newsletter 設置菜單中添加一個“純文本”選項。純文本設置面板有兩個選項：
為電子報自動生成純文本
當此選項設置為 “是” 時，會在發送電子報之前自動生成對應的純文本版本。
這會覆蓋電子報高級設置面板上的“文本版本”選項。
當此選項設置為 “否” 時，可以在電子報的編輯/高級面板上手動觸發創建純文本版本並進行必要的自定義。
為交易郵件自動生成純文本
例如：歡迎郵件、啟動郵件、道別郵件等交易郵件。
啟用此選項會覆蓋 Newsletter plugin 版本 7.0.0 之前用於歡迎郵件和啟動郵件的默認文本版本。
通過讀取電子郵件的 HTML 版本並刪除其格式，會創建純文本版本。圖像會被其“alt”標記替換，並使用括號顯示鏈接。
有關示例，請參閱我的博客。
此外掛與以下內容兼容：
WordPress 默認郵件程式，如果已配置
Newletter plugin 版本 7.0.9 以前的內置 SMTP 郵件程式
Newsletter plugin 的所有郵件傳送集成外掛（例如 SMTP、SendGrid 等）
Newsletter plugin 的超快速 Mailgun for the Newsletter plugin外掛
Mailgun for WordPress外掛，如果已配置使用 SMTP
某些其他第三方郵件外掛，例如WP Mail SMTP和Easy WP SMTP
此外掛不適用於替換 wp_mail() 函數的郵件外掛（例如Mailgun for WordPress 配置使用 HTTP API）。在這種情況下，"純文本選項" 頁面會顯示警告信息。

原文外掛簡介
The Newsletter Plugin is great for generating HTML newsletters. Its sophisticated Drag & Drop Composer makes it very easy to create a newsletter that looks good and renders well in a variety of email readers.
But it is generally considered good practice to include “plain text” version of the newsletter as well. For that reason, an automatic plaintext generation capability was added to the Newsletter plugin. However, that built-in capability does not apply to Raw HTML newsletters nor does it apply to transactional emails.
The purpose of this add-on is to add a plaintext generation option to all newsletters and emails sent by the Newsletter plugin.
For Raw HTML newsletters, this add-on adds the same “Autogenerate” / “Hand edited” dropdown on the Advanced settings tab that is also present for newsletters created using the Composer.
For transactional emails (such as the Welcome message, the Activation email, the Goodbye email), this add-on adds a global setting. Note that this will overwrite the default text versions generated by the Newsletter plugin for the Welcome message and the Activation email.
The plain text version is generated by code that is now part of the Newsletter plugin. It is created by reading the HTML version of the email and removing the formatting. Images are replaced by their “alt” tag and links are shown in brackets.
For an example, see my blog.
This add-on is compatible with
WordPress default mailer, if configured
all Newsletter plugin’s mail delivery integration add-ons (e.g. SMTP, SendGrid, etc)
the Superfast Mailgun for the Newsletter plugin add-on
the Mailgun for WordPress plugin when configured to use SMTP
certain other third-party mail plugins, e.g. WP Mail SMTP and Easy WP SMTP
This add-on is not compatible with mailer plugins that replaces the wp_mail() function (e.g. Mailgun for WordPress configured to use the HTTP API). In that case, a warning will be displayed on the Plaintext options page.
Please provide feedback on the Support forum. Thanks!
