Sending spam, viruses, ransom demands, and/or spearfishing from "known"
addresses is extremely common, so how effective that is depends a lot on the
sort of mail and the amount of mail you receive.
It is very common for me to get spam mail that appears to be from known
addresses, mostly clients and the less sophisticated family members (computer
sophisticated, at least) who have the bad habit of sharing their contacts with
whatever random app they download.

If a company insists on sending me advertising mail I do not want, I don't want
to do any business with that company.
