I rarely if ever introduce myself in cold emails. NOT introducing myself translates into a level of familiarity. Only strangers introduce themselves. Friends don't. And here you are… friend, community member, established business owner… they can look in your signature to see who you are.
An introduction in a cold email puts people into hypnosis that they're about to read spam or get pitched something. Emails that jump right in do the opposite. That's how I roll.
