Best Email Platforms for Product-Led Growth
Email platform recommendations for PLG SaaS companies. Self-serve onboarding, behavioral triggers, trial conversion, and product-driven sequences.
Product-led growth means the product drives acquisition, conversion, and expansion. Email supports this by guiding users through self-serve journeys, helping them discover value, and converting them when they're ready. PLG email is behavioral, contextual, and product-aware.
What PLG Email Looks Like
Behavior-Driven, Not Time-Driven
Traditional email sends based on time: "3 days after signup." PLG email sends based on behavior:
- "After first project created, but before second"
- "When trial user hits 80% of usage limit"
- "When user invites first teammate"
- "When engagement drops below threshold"
Product Data Integration
PLG email requires product data:
- Feature usage events
- Activation milestones
- Usage metrics
- In-app behavior
Self-Serve Optimization
Since there's no sales team, email must:
- Answer questions before they're asked
- Guide users past common friction points
- Provide clear next steps
- Drive conversion without human intervention
