Onboard Free UserAbout this email
This email from Hunter.io educates users on utilizing the Bulk Domain Search feature to find email addresses from multiple companies and domains simultaneously. It includes a direct, instructional tone supported by links to a video tutorial and a call-to-action button to try the feature immediately. The structure is clear and functional, combining helpful content with a user-friendly approach to encourage engagement and deeper product use.
Hunter.io journey
Why this works
**Why this works.** The subject line translates the feature (Bulk Domain Search) into a user outcome (companies to emails), so free users immediately see what problem gets solved instead of what button to click. The pattern here is "outcome before feature"; you can lift it for any onboarding email where you're nudging feature adoption and need free users to understand the payoff before they invest attention in learning.
