"It's bad to send emails with same the contents because almost ISP will mark you as a spammer, although you're not." I've reveiced lots of emails from customers said they didn't get confirmation emails after purchasing softwares. I guess them to look for emails in spam and trash folders. And they're always there. So software publishers are spammer? :d
May be I get rid of email promo??? Virus threaten and ISP's spam filter are killing email promo
