I want to sent at the beginning around 500 emails/day with some offers. Im not sure where i should start? I checked sites like: atompark, group-mail, authsmtp, mailchimp but I think they are very strict with the anti-spam rules. Will they ban me if i will send mails with offers? I could invest in software or services. I can buy domains if there would be needed, for example one domain for one campaign. I totally don't know where to start, do i need proxy, or domains, or software etc? I preffer to pay little bit more to don't do all staff on my own. I have lists of emails, my own message and thats all.
