My publicity email turned to spam. How can I fix this?

Because of the need to advertise one of the products of the company I work for, I had to send nearly a hundred emails (all of our customers) from my work account. The problem is, now I am getting feedback saying that my email address and the company's domain was treated as spam. How can I fix this so we can continue sending emails to our customers?


Please note this is not massive mail meant to be spam, but actual publicity of our products being sent to customers actually paying us for other services.

I THINK if you go into your email options (on my right side of the screen, almost to the top) you can correct this by resetting the spam filter. If not..hopefully someone with more experience can give you a better answer! good luck!
