Hello DP members i have big email list and i want to ask if can i create Google groups and add emails directly and begin to send them my new posts every day or 2 days They can unsubscribe if they want but i want to ask is that safe for site using adsense ?
It is safe until the point where people reports you to Google, that you are spamming. If they report you as spammer, you have a best way to be thrown out. Rather focussing email marketing to be the main source of traffic, use it as subordinate way of traffic.
Noooo .. be away from doing this , what you are doing is SPAM and google have a war on spammers these days , so keep away from spamming people or you may got closed your google account including adsense or maybe penalize your website from search results . Don't do this unless the list is owned by you , that you collect yourself , not download it from the internet .
