Adslot supports many options when it comes to requesting proposals for your campaign. The most common approach to take is via the dashboard. Here you can find the 'add publishers' button, search for the publisher or site and then add it to your plan. Next step is to select the 'request proposal' button and send each nominated publisher a short message or attachment and hit send. The dashboard will then update the status of the proposal(s) for you.
If you can't find a publisher from the search option simply send them an invitation and our team will get in touch with them to have them added into the platform for you.
The other option is to send a request via the planner section.
