Is it good or bad ??

[Walalayo]

Hi all,
I have my online job tips website. And I have a good number of email ids with me. I need to promote my websites new features through emails. Since email marketing is too costly, I planned to send it from my domain. I have the capability to send around 15000 emails per day. If I send 15000 emails per day from my domain using a script, then will it be anything like spamming?
