Below, we’re pulling insights from real onboarding email competitor benchmarks we’ve done for subscription-based B2C and D2C brands. These examples show how different brands approach onboarding with very different tactics, but similar goals: clarity, motivation, and momentum.

1. Welcome + “How It Works” Emails

Most onboarding journeys start here. The goal isn’t to explain everything, but to reduce uncertainty and set expectations.

2. Benefits-Focused Emails

Once users know what the product is, onboarding should shift to why it matters.
