PersistIQ does not have an option to reassign campaign, since that would create more challenges for the users. The issue is, if you continue using the same campaign but send from a new SDR, and the prospect replies to an older email sent by the original owner of the campaign, that reply will not get detected.
Alternative solutions might be:
Ending the existing campaign and creating a new campaign under the new SDR. Then, adding the prospects into the new campaign (clean start). The challenge is adding prospect back exactly where they were in the previous campaign.
Continue running the campaign under the original SDR's email and forward all of the responses to the new SDR, who will then take over.
