Cold Email

I've sent over 3,000 cold emails in the last year. For Scouter, for Prospect Organic, for partnerships, for sales. Some worked. Most of the early ones didn't. Everything below is what I learned from the ones that did – and the ones that flopped.

This is the complete cold email reference. Templates you can copy. Subject lines with open rate data. Personalization examples with before/after reply rates. Deliverability basics so your emails actually land. And the mistakes that kill most cold emails before anyone reads them.
