详情介绍:

WP Mail SMTP Plugin for Any Email Service Provider Are your WordPress emails not sending, landing in spam, or failing silently? FluentSMTP is a free WordPress SMTP plugin that fixes email deliverability by routing every wp_mail() call through the email service you choose: Gmail, Google Workspace, Amazon SES, SendGrid, Mailgun, Cloudflare Email, toSend, Postmark, Brevo (Sendinblue), SparkPost, Netcore, Elastic Email, SMTP2GO, Outlook / Office 365, Zoho, or any SMTP host. FluentSMTP talks to each provider's own API rather than only SMTP, so your transactional and marketing email goes out quickly and lands in the inbox. Set your From name and email, turn on email logging, add failure alerts, and route different senders to different providers, all from one screen. Connect as many email services as you want, and FluentSMTP routes each email to the right one based on its From address. [youtube https://www.youtube.com/watch?v=qnrTdQMNcuA]

常见问题:

Why are my WordPress emails not sending or going to spam?

By default WordPress sends email with the PHP mail() function on your web server, which is often unauthenticated, rate limited, or blocked outright by the host. Mailbox providers then reject or junk it. FluentSMTP sends your email through a proper email service or SMTP server instead, authenticated with your own domain, so it is delivered and lands in the inbox.

Can I send email via SMTP from my WordPress site using this plugin?

Yes. That is what the plugin is for: it takes over wp_mail() and sends through the SMTP server or email service you connect.

Is FluentSMTP really free?

Yes. There is no pro version, no paid add-on and no feature limit. Every provider and every feature is in the free plugin, and it will stay that way.

Can I connect Amazon SES API with FluentSMTP?

Yes. Add your SES access key and secret key, and FluentSMTP sends through the Amazon SES API rather than SMTP.

Can I send WordPress emails with Gmail or Google Workspace?

Yes. Connect your Google account with OAuth and FluentSMTP sends through the Gmail API. You can also use Gmail's SMTP server with an app password if you prefer.

Can I send WordPress emails with Outlook, Office 365 or Microsoft 365?

Yes. Connect your Microsoft account with OAuth2 and FluentSMTP sends through Microsoft's Graph API. Single-tenant Entra app registrations are supported.

Can I store my email service credentials in the wp-config.php file?

Yes. When you create a connection you choose where its credentials are kept: in the database, or in your wp-config.php file, which is what we recommend.

Can I send WordPress emails with SendGrid?

Yes. FluentSMTP connects to SendGrid over their API, which is faster than their SMTP endpoint. If you would rather use SMTP, you can set that up instead.

Can I send WordPress emails with Mailgun?

Yes. FluentSMTP connects to Mailgun with an API key, which is faster than their SMTP endpoint. If you would rather use SMTP, you can set that up instead.

Can I send WordPress emails with Brevo (Sendinblue)?

Yes. FluentSMTP connects to Brevo (formerly Sendinblue) with an API key. If you would rather use SMTP, you can set that up instead.

Can I send WordPress emails with SparkPost?

Yes. FluentSMTP connects to SparkPost with an API key.

Can I send WordPress emails with Netcore (Pepipost)?

Yes. FluentSMTP connects to Netcore (formerly Pepipost) with an API key.

Can I send WordPress emails with Cloudflare Email?

Yes. FluentSMTP ships a native Cloudflare Email Sending integration. Add your Cloudflare Account ID and an API token with Email Sending permissions, and the plugin will send through Cloudflare's REST API (including attachments, CC/BCC, Reply-To, and custom headers). The sending domain must be on Cloudflare with Email Sending enabled (SPF/DKIM/DMARC published).

Can I send WordPress emails with toSend?

Yes. FluentSMTP has a native toSend integration. Create an API key in the toSend dashboard, add your verified sending domain, paste the key into FluentSMTP, and your WordPress emails will be delivered through toSend.

How do I know if one of my connections has stopped working?

FluentSMTP checks every connection once a day. If one starts failing, from an expired OAuth token or a revoked API key, it is flagged on the dashboard and sent to your configured notification channels (Telegram, Slack, Discord or Pushover). You can also run wp fluent-smtp health from the command line at any time.

Can I use FluentSMTP from WP-CLI?

Yes. wp fluent-smtp test sends a test email, wp fluent-smtp health checks your connections, wp fluent-smtp stats shows sent and failed counts, and wp fluent-smtp prune-logs deletes old logs.
