Email – Send a Single Email

Send a Single Email Using SendGrid

Send a single HTML email from your application, CRM, website, or backend system using the Libwana.Net Email API.

Before sending email, get your API key from User Panel → Communication → API and keep it securely on your server.

Configure an active Email gateway such as SendGrid, verify the required sender or domain, and select the gateway under Communication → API.

If you need to send through a specific gateway, add its Libwana.Net gateway_identifier inside the contact object.
