Why Readability Matters for Cold Email

Cold emails written at a 6th–7th grade reading level achieve 3.5% reply rates — more than double the 1.6% rate for emails written at an 11th grade level. Readability isn't about dumbing down your message; it's about respecting your recipient's time and cognitive load. Simple, clear language communicates confidence and authority.
