Direct effects for Operations**

Large Audience Warnings Implementation
Users may experience confusion or frustration when they receive warnings about large email recipients, potentially leading to delays in communication and decision-making.

Lack of User Preparation
Without prior notification, users may not understand the purpose of the warnings, leading to misinterpretation of the feature as a restriction rather than a helpful tool.
