We classify welcome emails into four jobs: incentivize low-intent users in competitive markets, stand out for high-intent users in competitive markets, educate lower-intent users in emerging categories, or guide high-intent users toward the first useful moment. Choose one primary CTA and, when useful, one lower-commitment fallback. Source: [Welcome Emails](https://first1000.substack.com/p/welcome-emails).
