I keep seeing agency owners and sales teams blame AI for their declining cold email results. Lower reply rates, harder conversations, the whole spiel. The logic sounds obvious: everyone now has the same tools, the same personalisation systems, the same automation. Inboxes are crowded, prospects are harder to reach. But I think that's lazy thinking.
AI didn't cause this. It just exposed a rot that was already there.
Most people assume cold email is dying because competition increased. I'd argue it's dying because the quality of messaging became painfully homogeneous. AI makes it dead easy to create outreach that looks personalised - but looking personalised and being genuinely relevant are two completely different beasts.
Today, every other email drops in with a company name, a LinkedIn post reference, or a business milestone. On the surface, that feels sophisticated. yet prospects have caught on because they see the same patterns every single day. What once felt thoughtful now feels automated, no matter how fancy the tech behind it.
The best campaigns I've ever seen weren't built on personalisation alone. They were built on a deep understanding of the market. The sender knew the prospect's frustrations, knew the outcomes they chased, and knew why previous solutions failed. That made the message relevant, not just customised.
That distinction matters because relevance crushes personalisation. Personalisation can be pumped out by software. Relevance requires understanding. And understanding is damn hard to replicate.
after testing campaigns across markets, offers, and industries, the winners rarely had the most sophisticated tech stack. They had the clearest view of the buyer. Tech helps, but it's rarely the reason a campaign works.
As AI improves, this gap will only widen. Generating emails will become a commodity. Understanding a market deeply will stay valuable. Everyone will have the tools. Not everyone will have the insight.
That's why the future of cold email belongs to people who invest time in understanding their market, not to those chasing better prompts. When everyone uses the same tech, the advantage comes from knowing something about the customer that your competitors don't
