Cannot Launch Split-Run Campaigns
After you select Launch Split Run Campaign from the 
Actions menu (Not seeing this choice? Refer to the Side navigation bar changes topic.), the initial page displays all campaigns that are eligible for a split-run.
If no campaigns appear, verify that all the following requirements are met, then select Launch Split Run Campaign again:
- Each split-run launch must include at least two error-free campaigns.
- All selected campaigns must share the same list, as well as any other associated data sources (supplemental data sources, suppression lists, etc.).
- All selected campaigns must have identical email
domains to which campaign messages should not be sent.
Tip: You specify domain exclusions when selecting target contacts for the campaign.
