Can I set up a staggering sending in Qualtrics?

Hello all experts We're sending out our Customer Relationship Survey twice per year to a fairly substantial chunk of our customer base. Upon reviewing the feedback and response rates I found that some of the larger Enterprise Accounts had terrible response rates, given that they were targeted to receive a lot of the Survey invites. When I dug even deeper in to this I learned that their spam filter had caught 99% of the survey invites (including the reminders). The Survey invite email goes from a valid DNS record that basically looks like "feedback@company.com". The emails are all the same apart from the individual Survey link. One think that I suspect would be an issue is that Company X potentially could get 4000 basically identical survey email invitations in a very short time frame, and that this would trigger the spam filter to go nuts and catch them. Would you agree? So now my question is: Is there a way for me the plan the time of the distribution of the invitations so that I spread it out in chunks over several hours in order to try and fool the spam filters? So it's be like a staggering roll out of all the invitations. If so, how do I do that? Thanks again, and see you at X4 soon! -Mattias
