訂閱小組件
WordPress 訂閱小組件讓到訪你的 WordPress 網站的人們可以輕鬆訂閱你的行銷電子郵件，例如任何新聞報導、公告或促銷優惠等等。當他們註冊後，他們將自動收到確認資訊電子郵件，以便確認他們希望開始接收你的電子郵件。此確認動作構成「雙重確認」，是最佳的信件傳送方式。
多站網路
如果在多站網路環境下使用 Connect SendGrid for Emails 插件，必須進行網路啟用。之後，你可以在網路儀表板上存取設定頁面，並為所有站點使用相同的設定。
你可以在多站網路設定頁面中啟用 SendGrid 設定存取權限允許每個子站存取。如果復選框未勾選，則此站點將無法查看 SendGrid 設定頁面，並使用在網路上設定的設定。
注意！當你為子站啟用 SendGrid 管理時，該站點將無法發送電子郵件，直到管理員在該子站上更新 SendGrid 設定。
如果你已經在多站網路環境中安裝了該插件，並升級到 1.9.0 版本之後，可能需要重新配置插件。

原文外掛簡介
Connect SendGrid for Emails is a third-party fork of (and a drop-in replacement for) the official SendGrid plugin. This plugin is not endorsed by or affiliated with SendGrid. This plugin connects to an external service (the SendGrid API).
The Connect SendGrid for Emails plugin replaces WordPress’s default wp_mail() function by using either an SMTP or API integration with SendGrid to send outgoing email from your WordPress installation. It also allows you to upload contacts directly to your SendGrid Marketing Campaigns account via a subscription widget.
By using the Connect SendGrid for Emails plugin, you will be able to take advantage of improved deliverability and an expanded feature set, including tracking and analytics, to enhance user engagement on your WordPress installation.
The Subscription Widget
The WordPress Subscription Widget makes it easy for people visiting your WordPress site to subscribe to your marketing emails, such as any newsletters, announcements, or promotional offers you may send. Upon signup, they’ll automatically receive an opt-in email allowing them to confirm their desire to begin receiving your emails. This confirmation constitutes “double opt-in,” a deliverability best practice.
Multisite
If you are using the Connect SendGrid for Emails plugin in a Multisite environment, you need to Network Activate it. You can then access the settings page on the network dashboard and the configure settings will be used for all sites.
You can enable access for SendGrid settings to each subsite in the Multisite Settings tab. If the checkbox is unchecked then that site will not see the SendGrid settings page and it will use the settings set on the network.
Warning! When you activate SendGrid management for a subsite, that site will not be able to send emails until the admin updates the SendGrid settings on that subsite.
If you already had the plugin installed in a Multisite environment and you update to versions after 1.9.0 you may need to reconfigure your plugin.
