A nonprofit organization needs to import a list of donations made at a recent gala.

The correct order for importing data into Salesforce, considering multiple mailing addresses for donors, is:

Account: Import accounts first to establish the primary records.

Address: Import address records to link them to the appropriate accounts.

Contact: Import contacts next to associate them with the correct accounts and addresses.

Campaign: Import campaign records to track the event (gala) details.

Opportunity: Finally, import opportunities to record the donations linked to the appropriate contacts and campaigns.

This order ensures data integrity and correct relationships between the imported objects.
