An aside about ad spam from companies that I occasionally buy from:

Often as spam comes from the same mailbox as order receipts and includes words like “order” while messages with receipts never include the word “receipt”. When inundated with daily or sometimes multiple times a day ad spam from the same company it becomes very difficult to filter for only not receipts, to clean a neglected inbox.

After I’m gone, I fully expect my family just to delete it all because the signal to noise is so low.
