Splitting your campaign into two (or more) sendings
Splitting can be done when creating a new operation starting with a channel EMAIL action. Select the whole population targeted by your campaign as usual (in this case the full volume, which will be split between the different sendouts).
Creation of the campaign
Once the system finishes the calculation of targeted population, select the option Split Targeting when adding a sequence.
In the next view -- "Schedule" -- set the date / time of the first shipment:
Add split targeting
To add one or more actions (you are not limited to just two), click on gray "Split targeting" square:
First, select the number of branches you are interested in. Then inform the system which part of the total volume should be spread between these branches (actions). If you chose 100%, the whole volume will be divided between the branches, but only a random half if you chose 50%.
Set sending schedule
To set the sending schedule, click the part indicated by the arrow for each branch:
Then fill the information here:
This way you can program two or more sendings, each with its own date, hour, content, etc.
You still have one more thing to do to finish the setup. You need to assign a creative to each sendout.
