A user-behavior-driven email automation tool for SaaS onboarding.

The post highlights a crucial challenge for SaaS businesses: turning trial users into paying customers through well-timed and relevant follow-up emails. The opportunity lies in a specialized email marketing SaaS that triggers campaigns based on specific in-app user actions (or inactions), rather than just time-based delays. This product would integrate with a client's app to track events like 'feature_X_used' or 'invite_sent'. Marketing teams could then create flows such as, "If a user hasn’t exported a spreadsheet within 24 hours, send them a 'how-to' guide." This highly relevant follow-up is more effective than generic drip campaigns. Revenue would come from a tiered B2B subscription model based on the number of contacts or tracked events.
