"can't" use email section, so I will post my question here and hopefully get some answers. So I just tried to send a email to 200 customers through gmail to update them on the new stuff I will be selling. About half didn't go through because google thinks I'm sending spam. Is there any software or program that let me send 200~500 emails at once? My emails are all legit, no spam and all the customers know me. I would hate to send email to 10 people at once and do it 100 times.
