How this is measured
Every figure comes from real Walmart emails captured in Inbox Archive, not from a survey or a vendor report. Medians and the campaign mix appear once a brand has 12 campaigns archived, and the day and time charts once 12 of them are scheduled sends. “Typical E-commerce & Retail brand” is the median across the 24 E-commerce & Retail brands that clear the same bar, each counted once however much it sends. Campaign types are sorted automatically. Discounts are read from subject lines, and a copyable code counts only when one appears in the email, so offers applied at checkout are missed.
