In the same way that a news site can have categories for articles filed under news, opinion or sports, Tags allow you to sort and group proofs into different sections. This feature is really helpful for creatives who have a lot of proofs that are part of a larger project. By assigning proofs to a tag, creatives can easily reference which proofs have been completed, and they’ll know how much of their project is complete.
From the Send Page: To assign a proof to a tag, type in the name of the tag in the upload modal. You can either create a new tag, or select an existing one.
From the Proof Archive: You can add new tags, and also rename and archive your tags.
From the Proof Timeline: You can also modify the tags associated with a proof.
