How to write cold emails with AI that actually get replies
Mail-merge "Hi {firstName}" emails get 1-2% reply rates. Personalised emails referencing the recipient's actual job, recent LinkedIn post, or company website get 5-10%. The catch: hand-writing 100 personalised emails per day is impossible. AI personalisation closes the gap.
