I would like to survey 100 companies, but I still don't have the e-mail adresses and names of all the persons I will send the survey to. Is it possible to generate a token table for the information I have at the moment, send the survey to these people first, and then keep adding new contacts to the same token table thus sending the survey at different times?
Yes, with the token table you can import multiple groups at different times. We do it alot with out surveys that the information we need comes in at different times. Each time you import tokens, they information is just appended to your token table.
