WordPress Mail SMTP外掛
如果您的WordPress網站無法正確發送電子郵件，您並不孤單。超過三百萬個網站使用WP Mail SMTP可靠地發送電子郵件。
我們的目標是使電子郵件交付易於操作和可靠。我們希望確保您的電子郵件可到達收件箱。
WP Mail SMTP通過重新配置WordPress以在發送郵件時使用適當的SMTP提供程序來修復您的電子郵件傳送問題。
最重要的是，我們易於使用的設置嚮導和詳細的文檔會指導您完成整個設置過程。
什麼是SMTP？
SMTP（簡單郵件傳輸協定）是一種發送電子郵件的行業標準。適當的SMTP配置通過使用驗證來提高電子郵件交付率。
像Gmail、Yahoo、Office 365和Zoho這樣的常用電子郵件客戶端一直在與垃圾郵件發件人作鬥爭。他們查看的其中一點是郵件是否從聲稱的位置發件。
如果沒有正確的驗證，郵件要麼進入SPAM文件夾，要麼更糟糕的是根本不會傳送。
對許多WordPress網站來說，這是一個問題，因為默認情況下，WordPress使用PHP郵件功能來發送由WordPress或任何聯繫表單外掛生成的郵件，如WPForms。
問題在於，大多數WordPress主機公司並未將其服務器正確配置用於發送PHP電子郵件。
這兩種因素的結合導致您的WordPress電子郵件無法傳送。
WP Mail SMTP如何工作？
WP Mail SMTP插件通過改進和更改您的WordPress網站發送電子郵件的方式輕鬆解決電子郵件傳遞問題。我們重新配置wp_mail()函數，以使用適當的SMTP主機憑據或利用內置的SMTP郵件提供程序。
當使用我們內置的SMTP郵件提供商集成（建議使用）時，郵件使用提供商的直接API發送。這意味著即使您的Web主機封鎖SMTP端口，您的郵件也會成功發送。
這有助於解決所有WordPress無法發送電子郵件的問題。
WP Mail SMTP外掛包含許多不同的SMTP設置選項：
SendLayer（建議使用＃1）
SMTP.com（建議使用）
Sendinblue SMTP（建議使用）
Mailgun SMTP
SendGrid SMTP
Postmark SMTP
SparkPost SMTP
Gmail SMTP（Gmail、Google Workspace、G Suite）
Microsoft SMTP（Outlook.com和Office 365）[Pro]
Amazon SES SMTP[Pro]
Zoho Mail SMTP[Pro]
所有其他SMTP
對於大多數選項，您可以指定發件的“來自姓名”和“電子郵件地址”。
相比讓用戶為不同SMTP提供商使用不同的SMTP插件和工作流程，我們決定將它全部放在一起。這就是使WP Mail SMTP成為WordPress最佳SMTP解決方案的原因。
SendLayer
SendLayer是我們建議使用的第一個交易郵件服務。
其價格實惠和簡單的安裝使其成為完美的選擇。
原文外掛簡介
WordPress Mail SMTP Plugin
Is your WordPress site not sending emails? You’re not alone. 3+ million websites use WP Mail SMTP to send emails reliably.
Our goal is to make email deliverability easy so that your emails always reach the inbox.
WP Mail SMTP fixes your email deliverability issues by reconfiguring WordPress to use a proper SMTP provider when sending emails.
Best of all, our easy-to-use Setup Wizard and detailed documentation guide you through the process.
WP Mail SMTP is free and has everything you need to reliably send your WordPress emails!
WP Mail SMTP Pro unlocks even more powerful features like email logging, advanced email reporting and stats, backup connections, email alerts, smart conditional routing, and much more.
What is SMTP?
SMTP (Simple Mail Transfer Protocol) is an industry-standard for sending emails. Proper SMTP configuration helps increase email deliverability by adding authentication to the emails sent from your site.
Popular email clients like Gmail, Yahoo, Office 365, and Zoho are in a constant battle with email spammers, so they check whether emails are originating from a genuine sender. If the proper authentication isn’t there, emails either go in the SPAM folder or, worse, disappear.
This is a problem for a lot of WordPress sites. By default, WordPress uses the PHP mail function to send emails generated by WordPress or any contact form plugin like WPForms.
But most WordPress hosting companies don’t have their servers properly configured for sending PHP emails.
This is why WordPress emails aren’t delivered.
How does WP Mail SMTP work?
WP Mail SMTP plugin easily resolves email delivery problems by changing the way your WordPress site sends email. We reconfigure the wp_mail() function to use proper SMTP host credentials or an SMTP mail provider.
With our built-in SMTP mail provider integrations (recommended), emails are sent using the provider’s direct API. Even if your web host is blocking SMTP ports, your emails will still be sent successfully.
This helps you fix all WordPress not sending email issues.
WP Mail SMTP plugin includes many different SMTP mailers:
SendLayer (#1 Recommended)
SMTP.com (Recommended)
Brevo (formerly Sendinblue) SMTP (Recommended)

Configure an extra connection that kicks in if your primary connection fails. WP Mail SMTP automatically detects connection issues and automatically switches to the backup mailer. It will also automatically retry emails that failed.
Smart Conditional Routing
Create criteria to send different types of emails using different mailers. Filter by the contents of the email Subject or Message, From or To addresses, the plugin that generated the email, and more.
This allows you to mix transactional and marketing providers to improve deliverability.
