External Services

This plugin integrates with the SendGrid 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.
