Which methods for splitting email sends produce random test groups every time?
I was wondering which methods for splitting email sends for testing purposes produce random test groups every time so that if multiple tests are conducted over time that the same sample group is not always receiving version x and the other version y.
The desired state would be that the recipients are randomly placed into test or holdback groups and not the same users receiving the same variation every time or simply consistently falling into the holdback group that receives the winning version.
Does anyone know in detail how the groups are determined for each available method?
