DreamySites SMTP Mailer

By default WordPress sends email with the PHP mail() function. That mail is often blocked or lands in spam. DreamySites SMTP Mailer sends every wp_mail() email through the SMTP account you choose instead.

Set up in about two minutes

A four-step setup wizard opens right after activation:

• Choose your provider.

• Enter your login. The plugin tests it before moving on.

• Pick the From address.

• Send yourself a test email.

Features

• Presets for Gmail / Google Workspace, Outlook / Microsoft 365, Zoho Mail, your web host’s email, Brevo, SMTP2GO, SendGrid, Mailgun, Postmark, Amazon SES, or any other SMTP server.

• Test connection: checks the host, the port and your login without sending an email, and shows the full SMTP conversation with credentials hidden.

• Plain-English errors. “SMTP connect() failed” becomes “Your server cannot reach port 587. Try 465 or 2525, or ask your host to open outgoing SMTP.”

• Force From email, with the original sender kept as Reply-To. Contact form emails stop bouncing, and replies still reach the visitor.

• Email log with search, filters, failure reasons and optional message content. Old entries are removed automatically.

• Overview screen showing the delivery route, the last 14 days of sending and a delivery checklist.

• Deliverability checks: SPF, DMARC and MX records for your domain, plus a test of which SMTP ports your server can reach.

• Dashboard widget with sent and failed counts.

• The SMTP password is encrypted in the database. You can also keep it in wp-config.php instead.

• Port and encryption mismatches (like port 465 with TLS) are corrected automatically.

• Warns you when another SMTP plugin is active.

• Every feature is free. There is no paid version.

Trademark note: Gmail, Google Workspace, Outlook, Microsoft 365, Zoho, Brevo, SMTP2GO, SendGrid, Mailgun, Postmark and Amazon SES are trademarks of their respective owners. This plugin is an independent tool by DreamySites and is not affiliated with or endorsed by any of them. The presets only pre-fill standard, publicly documented SMTP settings.

External Services

This plugin does not send any data to DreamySites or to any analytics service.

Its one job is to deliver your site’s outgoing email through the SMTP server that you, the site administrator, choose in its settings. When WordPress sends an email (or when you click “Test connection” or “Send test email”), the plugin connects to that server and sends the email’s recipients, subject, headers, content and attachments, plus your SMTP username and password for authentication. Nothing is sent until you configure a server.

The provider presets only pre-fill a server address. You decide which service, if any, is used:

• Google Gmail / Workspace (smtp.gmail.com). Terms, Privacy

• Microsoft Outlook / Microsoft 365 (smtp.office365.com). Terms, Privacy

• Zoho Mail (smtp.zoho.com). Terms, Privacy

• Brevo (smtp-relay.brevo.com). Terms, Privacy

• SMTP2GO (mail.smtp2go.com). Terms, Privacy

• Twilio SendGrid (smtp.sendgrid.net). Terms, Privacy

• Mailgun (smtp.mailgun.org). Terms, Privacy

• Postmark (smtp.postmarkapp.com). Terms, Privacy

• Amazon SES (email-smtp.REGION.amazonaws.com). Terms, Privacy

The Deliverability screen looks up public DNS records (SPF, DMARC, MX) for the domain you enter using your server’s own DNS resolver, and opens test connections to the SMTP host you enter. No third-party API is used.
