This plugin integrates with the [SendGrid](https://www.sendgrid.com/) email delivery service to send outgoing emails via its API instead of the default `wp_mail()` function.

When enabled, the plugin communicates with the following SendGrid API endpoint: https://api.sendgrid.com/v3/mail/send

**Data sent to SendGrid includes:**
- Sender name and email
- Recipient email(s)
- Email subject
- Message body (text or HTML)
- Optional headers (Cc, Bcc)

The plugin requires a valid SendGrid API key to function. This credential is stored in your WordPress database and used only to authenticate API requests to SendGrid.
