Focus on breaking down the problem into manageable components. Start by considering the overall scale of Gmail users and their average email usage. Use publicly available data or estimates about the number of active Gmail users and the average number of emails sent per user per day. Then, calculate the total daily messages and convert that into a per-second rate. Be prepared to discuss your assumptions and any factors that might influence your calculations, such as peak usage times or spam messages.
