Which is more effective for outreach: cold calling detailers or DMing them to ask if I can send a Loom video pointing out a small mistake on their Google Maps listing, and then sending a personalized Loom if they agree?

I don't like this approach because you're just copying what everyone else does, and that rarely works well. You need a unique take—being a strategy copier rather than a tactic copier. If you only copy tactics, you'll be saturated as everyone else does the same thing, reducing value through supply and demand. Understanding the underlying strategy lets you go much farther. Instead of the trite 'Can I send you a Loom video I just recorded pointing out a problem?' actually do the work: record the video, show the exact mistake on their Google Maps listing, and offer to fix it for free to demonstrate your skill. This can deliver disproportionate value and potentially earn you $10,000 a month more. Focus less on hacky tricks like offering to send a Loom video and more on constant value delivery and doing the work consistently. If you can do that over time, you'll succeed. A smart move is to split‑test different methods for four to six weeks, then double down on what works. If you had to pick one outreach method to start with, I'd choose cold calling, but I don't think you should rely solely on either cold calling or DMing for Loom videos. If you do send Loom videos, make them custom for each person. Hopefully that clarifies my idea.
