Some people hate eshots, but most newsletters always have some offer that let's you save money or tap into exclusive sales before the rest of population does.
Don't mistake the eshot with spam. Spam is email that you didn't gave permission to the sender. Eshots require you to subscribe first to receive them.

Citizen#2 "Yeah.. I tapped the H&M VIP sale last week through the link in their eshot. They were trumpeting sale like there's no tomorrow for last 2 weeks, didn't you notice?"
Citizen#1 "WTF ?!?"
