SMTP Plugin Setup: Essential Tips
After installing your chosen plugin:
- Select an email provider and complete its authentication process.
- Use an appropriate sender address associated with your domain.
- Configure SPF, DKIM, and DMARC according to your email provider’s instructions.
- Send a test email and inspect the plugin’s error logs.
- Test contact forms, password resets, and WooCommerce order notifications.
- Keep the plugin updated and avoid running multiple SMTP plugins simultaneously.
Remember: SMTP improves the way WordPress sends email, but it cannot guarantee inbox placement. Provider reputation, DNS configuration, message quality, and recipient filtering also matter.
