Will sending a DM or email to a brand get me sponsored?

No. Both Robert Wilson from Boxo USA and Cam Douglas from Optima Batteries explicitly stated that sponsorships never come from DMs or cold emails alone. Robert mentioned he received a DM from a very high-profile racer that same day who deserves sponsorship, but it won't come from a DM. Instead, brands want you to meet them at events, build relationships over time, and demonstrate that you use and believe in their product before any sponsorship discussion begins.
