Outreach

Email Driver

Available Email Drivers

WP Outreach supports multiple email delivery methods:

DriverBest ForSpeedDeliverability
WordPress MailTesting, developmentSlowPoor
SMTPSmall to medium listsMediumGood
Amazon SESHigh volume sendingFastExcellent

WordPress Mail (Default)

Uses the built-in wp_mail() function. No configuration required, but not recommended for production use.

  • Pros: Works out of the box, no setup needed
  • Cons: Poor deliverability, often lands in spam, slow for large lists

Warning: Many shared hosts block or limit outgoing emails. WordPress Mail should only be used for testing.

SMTP

Send emails through an external SMTP server. Good balance of setup complexity and deliverability.

  • Pros: Better deliverability, works with any SMTP provider
  • Cons: Speed limits, requires SMTP credentials

Popular SMTP providers:

  • Gmail / Google Workspace
  • Outlook / Microsoft 365
  • SendGrid
  • Mailgun
  • Postmark

See SMTP Configuration for detailed setup instructions.

Amazon SES

Amazon Simple Email Service (SES) is the recommended driver for high-volume sending.

  • Pros: Excellent deliverability, very fast, cost-effective at scale
  • Cons: Requires AWS account, initial sandbox limitations

See Amazon SES Setup for detailed setup instructions.

Testing Your Configuration

After configuring your email driver:

  1. Go to WP Outreach → Settings → Mailer
  2. Click Send Test Email
  3. Enter your email address
  4. Check your inbox (and spam folder)

If the test email arrives successfully, your configuration is correct.

Troubleshooting

Test Email Not Received

  • Check spam/junk folder
  • Verify credentials are correct
  • Ensure your server can connect to the mail server (firewall rules)
  • Check WP Outreach logs for error messages

Connection Timeout

  • Your host may block outgoing SMTP connections
  • Try using port 587 instead of 465
  • Contact your host about email sending limitations
