This question already has an answer here:

We are trying to send out a mass email for a client of ours through a third party sender and it is always being sent to the spam folder rather than the inbox. I have below the headers from the email.

Do you have any thoughts on why it might be being filtered as spam? Or how we might be able to fix it?

This question was marked as an exact duplicate of an existing question.

it would be nice to see the bounce message instead. And to name the mass mailing provider and their server addresses. There are lots of different antispam techniques, you might be hitting any one of them – dyasny Nov 14 '13 at 18:03

You have to recognize that sending a mass email with spam-like capitalization in the subject line "NEW", marketing a medical product (CNET claims drugs and medicines comprise ~ 30% of all spam), sent from a server without the relevant SPF records might be taken the wrong way by spam filters. Presumably you're paying the third-party to carry out this mail campaign and if they're a professional mailing outfit then they should be well aware of that. – BlueCompute Nov 14 '13 at 18:36

The server you're sending from ( is not in your SPF record as a valid sender. Update your SPF record.

Thanks i will pass this along to who is sending out the emails for us. – user199394 Nov 14 '13 at 18:19
I'd fire who is sending out the emails for you, if that's their job. – ceejayoz Nov 14 '13 at 18:45
You should have control of the relevant SPF record not the third party sender. – BillThor Nov 15 '13 at 2:37
