There are lots of factors involved in regards to what day works best for your product. In General Tuesday is thought to be the best. But Tuesday now comes with heavy competition as there are launches every Tuesday.

What products work best for weekend launches? Any website that caters to the younger crowd or even home-based moms for that matter, sending emails on a weekend is preferred anytime over a weekday because the younger crowd and the stay at home moms generally check their emails on the weekend which is definitely not the case when it comes to emailing the working businessmen.

Working people usually like to check their emails during the office hours since they like to relax over the weekends.

What day works best for you really depends on who you are marketing to.
