  The writer has a parenthetic style.
• 差し込みさしこみCommon
  nounPhysical insertion: sticking or plugging something into an opening, as when you plug a cord into a socket — the noun of the verb 差し込む, "to stick in."
• 差し入れさしいれCommon
  noun, suru verb, transitive verbSeldom the word you want for "insertion": it really means delivering something to someone — a letter drop, or bringing a person food or drink as a treat.
• 組み込みくみこみCommon
  noun, suru verb, transitive verbInsertion as incorporation: fitting something into a larger whole so that it becomes part of it (inclusion). In printing it covers the cut-in, an illustration placed within the text.
• 折り込みおりこみCommon
  nounThe publishing sense: an insert — a loose sheet or flyer folded into a newspaper or magazine — or a foldout page. It is not the word for insertion in general.

Use 挿入 as the general word for putting something in, 「差し込み」 for physically sticking or plugging something into an opening, 「組み込み」 for incorporating something into a whole, and 「折り込み」 for printed inserts; 「差し入れ」 is seldom the right choice.
