When you land a sponsorship deal, do what you say you’re going to do. Be trustworthy.
Be ethical and responsible and ensure you also hold your sponsors accountable to what they said they were going to do.
Remind them of the importance of return on investment (ROI), return on objectives (ROO), or the measures they told you were so important during your negotiation phase.
How are THEY measuring the relationship? You aren’t able to tell them how many widgets they’ve sold as a result of your supporters buying or switching to their brand – it’s THEIR job to tell you that.
