If your program contains a campaign with a heavy section target, delivery can be delayed or even fail.
For example, an email used in 5 program variations, each with a 40M section target segment, killed the dedicated environment because the campaigns were scheduled at the same time.
- If the section target segment itself runs for more than 10 mins, you should be prepared for delays.
Avoid running campaigns at the same time if they have heavy section target. Consider instead replacing the section target with an exclude segment in the Automation Center.
