A campaign is an outbound marketing project that you want to plan,
manage, and track within Salesforce. It can be a direct mail program,
seminar, print advertisement, email, or other type of marketing
initiative. You can organize campaigns into hierarchies for easy
analysis of related marketing tactics.
Campaign members are the contacts and leads in your CRM that you included in the campaign and are trying to market to. If it's a direct mail campaign, its the people you sent the mailing to. If it's a seminar, it's the people that you invited. If it's an email campaign, it's the people you sent the email to. You can then track their activity, such as if they clicked on a link in the email, if they rsvp'ed for the seminar, and if they actually showed up, etc.
In Salesforce, when you visit a campaign record, the campaign members are a related list.
The Member First Associated Date is when the user was first added to a particular campaign. The Created Date is a Date/Time field that just notes when the campaign member record was created.
