New users sign up and forget about you by tomorrow
A good welcome sequence doesn't sell. It teaches users how to get value from your product, one email at a time.
When to use
You're seeing drop-off between signup and activation, and email is a viable channel for your users.
Hypothesis template
If we send a fill in: N-email welcome sequence teaching users to fill in: key actions, activation will improve by fill in: target% because consistent nudges prevent drop-off.
Method
The problem: Users sign up, poke around for 2 minutes, close the tab, and never come back. By tomorrow, you're forgotten.
What Grammarly does: Sends a carefully timed sequence after signup:
- Day 0: "Welcome! Here's how to install the extension" (the ONE action that matters)
- Day 2: "Did you know Grammarly works in Gmail?"
- Day 5: "Your weekly writing stats" (creates habit)
- Day 7: "Try these advanced features"
Why sequences work better than one email:
- One email = one shot at attention
- A sequence = multiple touchpoints when they're most likely to engage
- Each email teaches ONE thing (not overwhelming)
- Behavioral triggers catch people at the right moment
How to build yours:
- Map your activation milestones (what do retained users do in week 1?)
- Design 4-6 emails, each focused on ONE action
- Space them: Day 0, Day 1, Day 3, Day 5, Day 7
- Make each email actionable—include a button to do the thing
- Track open rates AND whether they actually do the action
Email principles:
- Short (under 150 words)
- One CTA per email
- Show, don't tell (GIFs, screenshots)
- Subject lines that create curiosity, not hype
- Send from a person, not "noreply@"
Success metrics
