WP Mail SMTP by WPForms

Description

WordPress 电子邮件 SMTP 寄件插件

Having problems with your WordPress site not sending emails? You’re not alone. Over 1 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.

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, and Office 365 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。

谷歌翻译:问题是大多数WordPress托管公司没有正确配置他们的服务器来发送PHP电子邮件。

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.

谷歌翻译:WP Mail SMTP插件包括四种不同的SMTP设置选项:

WP Mail SMTP插件包含许多不同的SMTP设置选项:

  1. Mailgun SMTP
  2. SendGrid SMTP
  3. Gmail SMTP
  4. Microsoft SMTP (Outlook.com and Office 365) [Pro]
  5. Amazon SES SMTP [Pro]
  6. 所有其他SMTP

谷歌翻译:对于所有选项,您可以为外发电子邮件指定“来自姓名”和“电子邮件地址”。

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。

Mailgun SMTP

谷歌翻译:Mailgun SMTP是一种流行的SMTP服务提供商,允许您发送大量电子邮件。 它们允许您每月免费发送前10,000封电子邮件。

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.

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.

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.

Microsoft SMTP (Outlook.com and Office 365)

Many business use Outlook.com or Office 365 to their to power their email. For those users, the Microsoft mailer can be a great option. This integration allows you to use your existing Outlook.com or Office 365 account to send your emails reliably.

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.

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.

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.

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, 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 Google and Mailgun, 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.

Reviews

Too many settings that where also not so easy to understand. I had to try another plugin
八月 16, 2019
Fails out of the box. Generic "Can't connect to SMTP server error". Address and credentials work in all other clients. Many have the same error and the answer always seems to be "Read PHPMail troubleshooting". I replaced with another plugin, all issues went away
八月 12, 2019
The site doesn't send emails despite smtp settings all setup, so we purchased the pro paid version as that is how you get support. After 1 week, no response from the support team despite the site advising 24 hour support time. Not worth spending money on this plugin.
八月 7, 2019
The plugin certainly does what its built for quite well, but the notices for delivery errors that can't be dismissed are extremely intrusive and obnoxious. In my case, I'm well aware of the issues that it might have when attempting to deliver messages to certain addresses, I don't need this plugin alerting me Every. Single. Time. with an irremovable admin notice. Just log the error somewhere. Hell, just make the notice dismiss-able. Because of how phoned-in this aspect of the plugin feels, I could reasonably assume the development team also phoned in the rest. In fact, the security advisory filed on this plugin earlier this year resulted in its complete removal from every client I manage. Evidence that other aspects of their work is half-assed? I know the only reason I currently use it now is due to a requirement of the client's IT team (despite my objections!)
八月 6, 2019
I've used this plugin on other websites with success. My most recent installation failed to authenticate. At first I thought it was an issue with the recipient mail server. However, when I tested the identical settings using another SMTP plugin, Easy WP SMTP, it worked without error. So the authentication failure clearly exists in WP Mail SMTP. Now I have to go back and check my other sites that are using this plugin.
