You might see this error after you have created a campaign and selected a
segment, and then after you click the Send Campaign button.
This error occurs due to the Segment you are using has been outdated which means the segment you selected is using conditions like leads campaign activity is more than 90 days old. You can see that the error has been highlighted by MailBluster. The selected Segment is marked in red and showing “Segment has been outdated”.
Now if you go to your campaign and further inspect, you will be able to resolve the issue. Go to your Draft campaign and click on the Standard Segment that you selected for this Draft campaign.
As you will notice, the segment will show a pop-up message showing that your segment is Outdated. Click on the Edit segment.
After clicking on the Edit segment, you will notice that the campaigns that are selected for this segment conditions (Here we used Campaign activity: did not open conditions) are more than 90 days old. So you need to keep in mind that you should not use those campaigns or segments which are 90 days old. This is because MailBluster now keep activities of campaigns for the last 90 days.
