We've introduced search filters to make it much easier to find your campaigns.
There are a range of filters you can use:
You can filter by status (active, draft, deactivated), by type (fixed, relative, immediate), by name or date order, or by searching for the name of the campaign.
By naming your campaigns uniquely, it will make filtering much more beneficial, so we recommend coming up with a methodology behind naming your campaigns. Instead of naming testing campaigns things like 'March 7th- test', or immediate campaign test, try to add custom variables that are easily searchable like "TEST: ______." The same concept can be applied to campaigns for Onboarding, Sales, etc.
