The biggest mistake I made was getting seduced by one channel - cold email looked so clean, like a perfectly curated grid. Monochrome, predictable. Worked beautifully at first, so I kept pouring everything into it. Then the replies dried up, and the whole aesthetic fell apart.
Had to pivot hard. Built a layered touchpoint strategy - LinkedIn, retargeting ads, email, faster follow-up. Timing and relevance matter way more than blasting volume. Also learned that a "good lead" isn't just someone who engages - vanity numbers are clutter. Started qualifying properly. Fewer leads, but the conversions actually felt like they belonged in the brand story.
