We are a training & employment related govt. not-for-profit organization.

We send out emails to students (registered for our services) on a regular basis regarding job vacancies. 

We strictly do note send out any marketing/promotional emails.

I would like to increase the limit on email being sent out, it is currently 150 or 200.

Kindly help me resolve this issue

p.s. we have around 2000 registered students who avail our service
