# Overview 

### Overview 
Connect Invitation API offers the capability to effortlessly send Connect invitations to your users. It is underpinned by Atto's outbound email solution which supports dynamic components that provide flexible email content and customisation. The email subject, sender address and message will be configured in the email template for you by our support team.
Get immediate feedback about email delivery using our [v2 webhooks](/content/docs/guides/platform-integration/notifications#v2-webhooks), which will inform you if the invitation email's state has been `Sent`, `Received`, `Opened`, `Clicked`, or `Failed`. This provides additional tracking possibilities to build more sophisticated workflows based on time period and see if the customer has actioned a Connect Invitation email during the configured period.
