Which activity allows you to send an email without entering the username and password of the email account?

The ability to send an email without entering the username and password of the email account is primarily found in the option that utilizes integrated email applications, such as Outlook. When using the activity designed for Outlook, the application connects to the email account using the logged-in user's credentials. This means the automation can access the email application directly if the user is authenticated and running the process in an environment where Outlook is already set up.

This functionality is crucial for scenarios where security is a concern, as it eliminates the need to store sensitive credentials in automation scripts or workflows. In contrast, other activities often require explicit authentication information to connect to the email service, thereby making them less secure or more complex in settings where credentials management could be an issue.

Using the Outlook-based activity simplifies the process, as it leverages existing user authentication, reducing potential vulnerabilities associated with handling email server details. This showcases the ease and safety of interacting with email services through established applications, reinforcing best practices in automation.
