Capturing email address with an anonymous survey link

Hi, We are looking to distribute a large number of survey invites using our internal tool (mass distribution). Before Qualtrics we were using another survey tool that was capable of capturing the email address of the respondent using modified anonymous link. I know how to set a static value to the anonymous link, however, have no idea if we can achieve our goal the same way using Qualtrics. We cannot generate links due to a really large number of targeted respondents and we are not allowed to distribute the survey using Qualtrics mailer either.
