The two definitions
Service package. An agreement in which a publicist or agency delivers defined PR work for a client, such as pitching media, writing and distributing press releases, and publicizing events. The client pays the publicist; coverage is earned from editors.
Gift box. Free products a brand mails to creators or influencers, usually with branded packaging, in the hope of an unboxing post or review. The creator usually pays nothing and typically has no obligation unless a paid deal exists.
Susan von Seggern's work is the service kind. Gift boxes overlap with it only at events, where exhibiting at gifting events and gift bag inclusions are part of her event PR framework.
