I'm new here and excited to talk about email marketing with all of you :-)

In my opinion, email marketing should be used to provide value to your subscribers. If you don't have anything interesting to share with them, don't send an email. Despite this belief I noticed many ecommerce stores are doing the complete oppoisite. This leads me to my question.

Why do so many large ecommerce stores simply blast out a product recommendation email every single day (Fab, Wayfair, Ice, ext..)?
