What happens when a contact unsubscribes, are they unsubscribed to all lists?

When a contact/prospect/lead unsubscribes from a mailing or mailing list, the response is based on whether the Add Any Unsubscribes to Global Suppression List option is enabled or disabled, in Settings > Company Profile > Unsubscribe Options:

• Disabled - The contact is opted out of the list from which they unsubscribed.
• Enabled - The contact is unsubscribed from all lists of which they are a member and their email address is added to your email Suppression List. For more information, see Suppression List.
• The effect on campaign metrics:
  • If a recipient has opted out of all contact lists, they will be unsubscribed without tying them to campaign metrics.
  • If a recipient unsubscribes from the list(s) associated only with the campaign, then their action will be presented in the campaign metrics.

When unsubscribing, email recipients can choose to unsubscribe from all future emails from the current mailing list or manage their communication preferences for all future mailings.

If they elect to manage their preferences, they see three options:

• All future communications - subscribe to all mailing lists of which they're a member
• Only selected email communications - subscribe on a list-by-list basis
• I do not wish to receive any further email communications - opt out of all mailing lists

Note: For multiple subscription accounts, the contact list is shared across all accounts.
