It's somewhat interesting, but really annoying the email traffic I get advertising the same minimal off SALES. If I haven't responded after a few attempts, why do they assume I'll respond after 10 or 20? It's the same stuff and same discount, repeated and repeated.
If you want to triple your emails, just click once on one of those emails.... (Fortunately, block and unsubscribe buttons seem to work a lot better than they did in the past.)
