What it does
By default, WordPress sends email with the PHP mail function, which many hosts handle poorly and many inboxes treat as suspicious. The result is missing form notifications and confirmations that land in spam. This plugin connects your site to a proper sending service instead, using authenticated SMTP or provider APIs. You can pick a supported service such as SendGrid or Postmark, or enter custom SMTP settings to work with almost any email provider.
Once a provider is set up, you can send a test email to any address to confirm everything works before relying on it. A setup wizard walks you through configuration, and you can switch between enabled providers as your needs change. Every message is recorded in an email log with status, timestamps, sender and recipient details, which makes troubleshooting much easier. It is built with Gravity Forms users in mind and fits into existing form workflows.
Best for
- WordPress sites running Gravity Forms that rely on notifications
- Businesses whose contact or order emails land in spam
- Agencies managing email delivery across client sites
