There is a fantasy themed candle company that emails me daily. My god it annoys me, but I also I buy so many candles. At my day job, we did a test around sending more emails and longer emails. Initially the more we sent, the more our core metrics and NPS went up. Then as we sent even more, our NPS starting dropping but our core metrics kept going up. It was rather interesting. There is definitely a balance to be had but my takeaway is that annoying your users a bit might be ok for business.
