WordPress 电子邮件 SMTP 寄件插件

Having problems with your WordPress site not sending emails? You’re not alone. Over 2 million websites use WP Mail SMTP to send their emails reliably.

Our goal is to make email deliverability easy and reliable. We want to ensure your emails reach the inbox.

WP Mail SMTP fixes your email deliverability 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.

什么是SMTP？

SMTP (Simple Mail Transfer Protocol) is an industry standard for sending emails. Proper SMTP configuration helps increase email deliverability by using authentication.

Popular email clients like Gmail, Yahoo, Office 365, and Zoho are in a constant battle with email spammers. One of the things they look at is if an email is originating from the location it claims to be originating from.

If the proper authentication isn’t there, then emails either go in the SPAM folder or worst, don’t get delivered at all.

谷歌翻译：这是很多WordPress网站的问题，因为默认情况下，WordPress使用PHP邮件功能发送WordPress生成的电子邮件或任何联系表单插件，如WPForms的。

The issue is that most WordPress hosting companies don’t have their servers properly configured for sending PHP emails.

谷歌翻译：两者的组合导致您的WordPress电子邮件无法送达。

WP Mail SMTP如何工作？

WP Mail SMTP plugin easily resolves email delivery problems by improving and changing how your WordPress site sends email. We reconfigure the wp_mail() function to either use proper SMTP host credentials or leverage a built-in SMTP mail provider.

When using one of our built-in SMTP mail provider integrations (recommended), emails are sent using the provider’s direct API. This means even if your web host is blocking SMTP ports, your emails still send successfully.

This helps you fix all WordPress not sending email issues.

WP Mail SMTP plugin includes many different SMTP setup options:

  1. SMTP.com (Recommended)
  2. Sendinblue SMTP (Recommended)
  3. Mailgun SMTP
  4. SendGrid SMTP
  5. Postmark SMTP
  6. Gmail SMTP
  7. Microsoft SMTP (Outlook.com and Office 365) [Pro]
  8. Amazon SES SMTP [Pro]
  9. Zoho Mail SMTP [Pro]
  10. 所有其他SMTP

For most options, you can specify the “from name” and “email address” for outgoing emails.

谷歌翻译：我们决定将其全部集于一身，而不是让用户为不同的SMTP提供商使用不同的SMTP插件和工作流程。 这就是使WP Mail SMTP成为WordPress的最佳SMTP解决方案的原因。

SMTP.COM

SMTP.com is a recommended transactional email service.

With over 22 years of email delivery expertise, SMTP.com has been around for almost as long as email itself. They are known among internet providers as one of the most reliable senders on the internet.

Their easy integration process lets you start sending emails in minutes and benefit from years of experience. SMTP.com provides users 50,000 free emails the first 30 days.

Read our SMTP.com documentation for more details.

Sendinblue SMTP

Sendinblue is a recommended transactional email service.

They serve 80,000+ growing companies around the world and send over 30 million emails each day.

Their email deliverability experts are constantly at work optimizing the reliability and speed of their SMTP infrastructure. Sendinblue provides users 300 free emails per day.

Read our Sendinblue documentation for more details.

Mailgun SMTP

Mailgun SMTP is a popular SMTP service provider that allows you to send large quantities of emails. They provide 5,000 free emails per month for 3 months.

谷歌翻译：WP Mail SMTP插件提供与MailGun的本机集成。 您所要做的就是连接您的Mailgun帐户，您将提高您的电子邮件传送能力。

Read our Mailgun documentation for more details.

SendGrid SMTP

谷歌翻译：SendGrid有一个免费的SMTP计划，您可以使用它每天发送多达100封电子邮件。 通过我们的本机SendGrid SMTP集成，您可以在WordPress站点上轻松安全地设置SendGrid SMTP。

Read our SendGrid documentation for more details.

Postmark SMTP

Send emails securely using your Postmark account with our API integration. You can sign up for a free trial without a credit card, which allows you to send up to 100 emails per month.

Read our Postmark documentation for more details.

Gmail SMTP

谷歌翻译：博主和小企业主通常不想使用第三方SMTP服务。 那么您可以使用Gmail或G Suite帐户来收发SMTP电子邮件。

谷歌翻译：这允许您使用专业电子邮件地址并改善电子邮件的可传递性。

谷歌翻译：与其他Gmail SMTP插件不同，我们的Gmail SMTP选项使用OAuth对您的Google帐户进行身份验证，确保您的登录信息100％安全。

Read our Gmail documentation for more details.

Microsoft SMTP (Outlook.com and Office 365)

Many businesses use Outlook.com or Microsoft 365 to power their email. Our Microsoft mailer integration allows you to use your existing Outlook.com or Microsoft 365 account to send emails from WordPress for better deliverability.

Read our Outlook and Microsoft 365 documentation for more details.

Amazon SES SMTP

Advanced or technical users can harness the power of Amazon AWS (Amazon Web Services) with the Amazon SES mailer. With this integration, you can send a high volume of emails at a very reasonable rate.

Read our Amazon SES documentation for more details.

Zoho Mail SMTP

Send emails using your personal or business Zoho Mail account, all while keeping your login credentials safe.

Read our Zoho Mail documentation for more details.

其他 SMTP

谷歌翻译：WP Mail SMTP插件还适用于所有主要的电子邮件服务，如Gmail，Yahoo，Outlook，Microsoft Live以及提供SMTP的任何其他电子邮件发送服务。

您可以设置以下选项：

  • 指定一个SMTP主机。
  • 指定一个SMTP端口。
  • 选择SSL / TLS加密。
  • 是否选择使用SMTP身份验证。
  • 指定SMTP用户名和密码。

Email Log

Email Logging lets you log and view all emails sent from your site. Email logs are helpful for storing emails for your records, auditing outgoing emails, and debugging during site development.

But that’s just the beginning. Our powerful WordPress email logs unlock extra tools to help you measure email engagement and improve email deliverability:

Resend Emails

You resend any email or forward it to one or more email addresses, right from your email log. From the overview page, you can also resend multiple emails in bulk. This is an awesome way to resend emails that failed or forward important emails to an alternative email address.

Track Email Opens and Clicks

Wondering if an important email was actually opened, or if any links in the email were clicked? Our email log lets you view open and click tracking stats for your WordPress emails.

Store Email Attachments

WP Mail SMTP lets you store all of the email attachments that are sent from your WordPress site. That makes it easy to review an attachment or archive it locally.

Export Email Logs

Easily export your WordPress email logs to CSV, EML, or Excel. You can filter the email logs before you export and only download the data you need. This feature lets you easily create your own deliverability reports. You can also use the data in 3rd party dashboards to track deliverability along with your other website statistics.

Print Emails

Once you’ve activated email logging, any individual log file can be printed in an easy-to-read format. If you want to archive an email log digitally, it’s easy to export it to a PDF document too.

Manage Multisite Email Logs Easily

WP Mail SMTP makes it easy for Network Admins to view and manage email logs for subsites. You can access all of your deliverability information from the Network Admin dashboard and quickly switch between subsites. That makes it easy to review email logging data for all subsites on one centralized page.

Email Reports

Email reports make it easy to track deliverability and engagement at-a-glance. Your open and click-through rates are grouped by subject line, making it easy to review the performance of campaigns or notifications. The report also displays Sent and Failed emails each week so you spot any issues quickly. You’ll also see an email report chart right in your WordPress dashboard.

Weekly Email Summary

Get statistics about WordPress emails sent directly into your inbox. Our weekly emails reveal how many emails are being sent from your WordPress site, and which ones are getting opens and clicks. The Summary also shows you deliverability statistics at-a-glance so you can spot any issues without logging into WordPress.

Manage WordPress Emails and Notifications

The Manage Notification feature gives you full control over which email notifications WordPress sends. This means you can disable different WordPress notification emails. Don’t want to receive emails when new users are created? No problem, turn it off.

WordPress Multisite Network Settings

For users running a multisite network, our network settings provide a centralized location to easily configure your SMTP settings for all sites, saving you time.

Expert Support

We provide limited support for the WP Mail SMTP plugin on the WordPress.org forums. Access to our world class one-on-one email support is available to WP Mail SMTP Pro users.

White Glove Setup

Our White Glove Setup service is a great option that anyone can benefit from. Whether you don’t have the time or maybe you feel a bit in over your head – we’ve got you covered.

You can sit back and relax while we set up everything for you. White glove setup includes WP Mail SMTP plugin installation and setup, configuration adjustments to your DNS for proper email domain name verification, SMTP.com or Mailgun setup, and final testing to confirm everything is passing with flying colors.

Security

The WP Mail SMTP team takes security very seriously. Not only does the plugin follow all security best practices, but we have several options available to ensure your site is safe and secure.

  • Direct SMTP mailer integrations (recommended), such as SMTP.com, Sendinblue, Mailgun, SendGrid and Postmark, use the official provider APIs. This means you never enter your username or password in the plugin settings and these credentials are not stored in the database. Instead, we use tokens or API keys which are much more secure.

  • When using Other SMTP mailer, we provide the option to insert your password in your wp-config.php file, so it’s not visible in your WordPress settings or saved in the database.
