We should be able to have more than one criteria of each type to create a segment (i.e. I should be able to create a segment that targets people who meet BOTH of these criteria: were sent any of the last 5 campaigns AND Opened one of the last 10 campaigns.
We’re updating the status of this idea to Under Consideration while we look into adding NOT and IS BLANK operators into segment creation. This would allow for more flexible uses of segments. There will be other criteria considered, so we still encourage everyone to share their desired segment use cases below in the comments. We will keep this thread updated with progress, it will likely still take some time before we’re able to fully tackle this one.
