Question: For a global study, we’d like to send out around personalized 250’000 Emails. We’d like to distribute the emails over several weeks. We have a plan for our email distribution and would like to send out roughly 16’000 Emails per day. We created subsamples that contain around 16’000 participants and we know how to schedule the email distribution for each subsample.

Say: Sample 1 gets an invitation on day 1, sample 2 gets an invitation on day 2 etc. Here’s the problem: Instead of sending out 16’000 Emails at once on a given day we would like to send them out in 30 Minute intervals. So Send out the first 1000 Emails of Sample 1 at 10:00, then send out the next 2000 Emails of Sample 1 at 10:30 etc. I know that it’s possible to create more Subsamples and schedule each distribution seperately. However, does Qualtrics allow a Subsample to be distributed in intervals? So that Sample 1 (16’000 Emails) gets sent out in 30 minute intervals without us having to individually schedule each interval of a 1000 emails?

Thanks in advance
