We're using a Smartsheet to gather information at several sites. On each line is an email address to which an Update Request Form is being sent to ask that person to supply information about that line. Today was the first time we used it for real. Nineteen unique email addresses were used (some addresses were on multiple lines). I got an email from Smartsheet telling me that seven of them were not successful, but apparently the other twelve were.
I should note that the email addresses being used are all in one email domain belonging to a client of ours that is a very large company where employee turnover can be expected.
I'm wondering if these share-attempts failed because the email addresses are no longer valid, and the bounce-back emails the Smartsheet server received initiated the email to me telling me they failed. That's the crux of my question here - how does Smartsheet deal with invalid email addresses, and can they cause a notification that the sheet failed to be shared with those people?
