Campaigns are mailing lists of contacts. There are two different ways contacts can be added to the campaign: “static” and “dynamic”.
“Static” campaigns contain manually added contacts (bulk addition is supported), while “Dynamic” campaigns use simple filters to dynamically pull in contacts.

Static campaigns are simple lists of contacts.

Dynamic campaigns are created with filters that form the actual list of contacts at the time the campaign is sent.

This is an easy way to have campaigns that are up-to-date with respect to accounts, tiers and roles.

Normally, the Campaigns page shows only the campaigns created by the currently logged-in user. To see all the campaigns, click on the “filters” button and manually deselect the person in the “Created By” filter.
