I am curious. Lets say, I post a job ad on craigslist looking to fill XYZ job. The people on craigslist reply to the ad and I send a vacation auto responder e-mail notifying them that I received their e-mail and that they can visit our website to read up about the company/position etc. This company site has google adsense on it and I don't want to get my client's adsense account banned for this. I know people have gotten banned for spamming craigslist etc. Do you think this would be a bannable offense? I don't want to get my client's adsense account banned.
you can't send mass email to anyone on ur website but i think u can send email to interested people about ur website. Say these people join a group called php tutorials and ur website is on php tutorials. You can always email google at ur own risk.
I dont think you will have any problem as long as you don't mention about asking them to click ads in the newsletter.
