WP Mail SMTP by WPForms

描述

WordPress 电子邮件 SMTP 寄件插件

在您的WordPress站点上遇到了无法发送邮件的问题?您并不孤单。目前有超过200万个网站正在使用WP Mail SMTP来可靠地发送邮件。

我们的目标是让电子邮件的递送变得简单而可靠。我们希望确保您的邮件能够送达收件箱。

WP MAIL SMTP通过正确配置WordPress在发送邮件时使用的SMTP提供程序来修复邮件的可达性。

最重要的是,我们简单易用的设置向导和详细的文档能指导您完成整个过程。

什么是SMTP?

SMTP(简单邮件传输协议)是发送电子邮件的行业标准。正确的SMTP配置有助于通过使用身份验证来提高电子邮件的传递性。

Gmail、Yahoo、Office 365和Zoho等流行的电子邮件客户端都在不断地与垃圾邮件发送者进行着斗争。他们关注的问题之一是,电子邮件是否真实的来自其声称的发件地址。

如果没有正确的身份验证,泽电子邮件会进入垃圾邮件文件夹,更糟糕的甚至根本无法送达。

这对于很多WordPress站点来说是一个问题,因为默认情况下,WordPress使用PHP MAIL函数来发送WordPress或其余联系表单插件生成的邮件,如WPForms联系表单插件

问题是大多数主机服务没有为PHP的邮件传递正确配置其服务器。

两者结合会导致WordPress的邮件无法送达。

WP Mail SMTP如何工作?

WP Mail SMTP插件通过改进和更改您WordPress站点的电子邮件发送方式,轻松解决电子邮件发送问题。我们重新配置了wp_mail()函数,以使用正确的SMTP主机凭据或是内置的SMTP邮件提供程序。

当使用我们集成的内置SMTP邮件提供程序(推荐)时,电邮将直接使用提供程序的API进行发送。这意味着即使您的网站主机被屏蔽了SMTP端口,您的邮件仍然可以成功发送。

This helps you fix all WordPress not sending email issues.

WP Mail SMTP插件包含许多不同的SMTP设置选项:

  1. SMTP.com (推荐)
  2. Sendinblue SMTP (推荐)
  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

对于大多数选项,您可以为发出的邮件指定“发件人名称”和“邮件地址”。

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。

电邮日志

通过电邮日志,您可以记录和查看从您的站点发送的所有邮件。电邮日志可帮助您存储电子邮件以供记录,审阅发出的邮件以及在站点开发过程中进行调试。

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.

管理WordPress的电邮和通知

管理通知功能让您可以完全控制WordPress发送的电子邮件通知。这意味着您可以禁用不同的WordPress通知邮件。不想在创建新用户时收到邮件?没问题,将其关闭。

WordPress多站点网络设置

对于运行多站点网络的用户,我们在网络设置中提供了一个集合的设置位置,可以轻松地为所有站点配置SMTP,节省您的时间。

专业支持

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.

白手套设置

我们的白手套设置服务是一个极佳的选择,任何人都可以从中受益。无论您是没有时间,还是觉得有点力不从心,我们都会为您提供服务。

有我们来为您设置好一切,您可以坐下来放松。白手套设置包括WP MAIL SMTP插件的安装及设置,对您的DNS进行配置调整以确保电子邮件域名验证正确设置,对SMTP.com货Mailgun进行设置,然后到最终测试以确认一切顺利完成。

安全

WP Mail SMTP团队非常重视安全性。该插件不仅遵循所有安全性最佳做法,而且我们提供了多种选择来确保您的网站安全。

  • 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.

  • 当使用其他SMTP邮件程序时,我们提供了将密码插入到 wp-config.php 文件中的选项,因此在WordPress设置中不可见,因为它未被保存在数据库中。
