Automated alert containing a form to contacts outside of contact list in a sheet
I am trying to create an automated workflow that will alert hypothetical meeting participants with an additional message containing a separate Smartsheet form link. However, I am receiving an error message that some contacts (emails) are not being notified in my inbox. These contacts are not part of my contact list; however, that is one of the requirements for this project to be successful as there will not be visibility of all contacts emails before-hand i.e they are not employees. The participant list will be submitted by the meeting coordinator as email addresses.
I have gone in and changed my Automation settings to "Unrestricted" and made new workflows and forms after making the change. This did not solve the issue and I am still receiving the notification error for email addresses not part of my company's established contact list.
As I've described this, does anyone notice any issues in my logic or wording on how to enable this process? Recommendations on a new process?
