Adjacent-product onboarding email loop
Use your main product's onboarding emails to introduce one adjacent tool or feature that solves a near-term follow-on job for new users.
Why this can grow a startup
New users are already opening your onboarding emails to understand the product they just signed up for. That makes the sequence one of the cheapest high-attention surfaces you own. If the adjacent product is genuinely useful in the same workflow, the email becomes more than a cross-sell. It turns activation in product A into discovery for product B without buying another audience.
Source-backed example
Buffer noticed that only about 10% of new users were creating Start Pages, so it added Start Page promotion into the main Buffer onboarding sequence. The onboarding emails alone doubled traffic to the Start Page landing page from January to March, and Buffer later reported that 73% of new Start Pages were created by new Buffer users.

When to use it
Use this when Email, Lifecycle, Product is relevant to activation, cross-sell, retention and you can run a bounded test with a free budget.
When not to use it
Do not use it as a substitute for customer evidence, a clear owner, or a measurable stop condition. Local platform rules and market behavior still need checking.
How to do it
- Choose one target segment and define the exact next action this tactic should prompt.
- Adapt the tactic to Email and Lifecycle, using evidence from Buffer Open Blog as context—not as a promised result.
- Record a baseline for: Share of target users completing the product's first-value action. Set a guardrail that would make you pause the test.
- Run a narrow pilot and choose a test window that fits the normal decision or use cycle; do not scale before you have observed the full cycle.
- Compare the signal with its baseline. Scale only if the intended action improves without crossing the guardrail; otherwise revise one variable or stop and record what you learned.
