To demonstrate the power of one-on-one, we sent a DM to each marketing manager, where the actual sender was the marketing manager themselves. The DM was designed with the recipient brand's corporate profile reflecting a current marketing challenge the recipient faced. The marketing managers were then asked to log on to a website, where we invited them to lunch.

The results (so far): 100% response rate - three meetings, and invitations to submit creative reviews with all of them!
