Time for a different approach entirely. How surgical are your emails? There's an ocean of data in this space if you know where to look.
There are tools that scrape Google's SERPs to tell you whether a business is even running Google Ads right now. Their estimated CPC, whether their homepage loads like a brick, how users feel about the site experience. All sitting there in the public domain.
Think of it like fishing with a spear instead of a net. You can see exactly where the fish are bleeding. Slow load times, poor ad relevance, low Quality Scores - these are wounds. You've got a library of case studies from similar industries where you closed those wounds and improved their numbers. That's your bait.
That data becomes the backbone of your outreach. You mention a specific pain point you spotted, back it with a number, point to a result you delivered for someone in the same situation. Then when you ring them, you're not reading a script - you're having a conversation about their actual business.
The scattergun approach just burns domains and goodwill. It's like shouting into a crowd and hoping someone mistakes noise for authority.
I've been doing this long enough to know that the difference between spam and a genuine offer is specificity. The numbers give you that. Build your targeting around what the search results are already telling you.
