Trigger-Based vs Batch-and-Blast
Batch-and-blast is the old model: send the same email to your entire list on Tuesday morning. Relevance is low; unsubscribe rates are high; conversion is minimal. Trigger-based automation sends the right message to the right person at the moment a specific behaviour occurs — and is 5–10× more effective by every metric.
Examples of effective behavioural triggers for India SaaS:
- User signs up → onboarding sequence starts immediately
- User hasn't logged in for 7 days → re-engagement email + WhatsApp nudge
- User completes core action for the first time → in-app celebration + upsell prompt
- User approaches usage limit → upgrade prompt with ROI framing
- Contract renewal 60 days out → automatic QBR scheduling trigger to CSM
Channel Mix for India
Email: Still essential for B2B lifecycle; 15–25% open rates; best for detailed content (feature updates, QBR prep, invoice summaries). SMS: High open rates (>90%) but limited to short, transactional messages; critical for payment reminders, OTPs, and alerts. WhatsApp: 85%+ open rates; conversational; ideal for onboarding nudges, support follow-ups, re-engagement, and transactional updates. Push notifications: Effective for consumer and mobile-first products; declining effectiveness on web; best for time-sensitive alerts. In-app messages: Highest relevance; zero delivery cost; best for feature discovery and upsell prompts when user is already engaged.
