The API-First Email Marketing Challenge

API-first companies have a unique relationship with their users. Your customers are developers who integrate your API into their own products. They do not browse your marketing site—they read your documentation. They do not respond to promotional offers—they respond to technical content that helps them build better integrations.

Your email marketing must reflect this. Developer onboarding emails should include code snippets, not stock photos. Usage alerts should show request counts, not engagement scores. Product updates should include breaking changes and migration guides, not feature highlights with emoji.

The Integration Completion Problem

The single biggest drop-off point for API companies is between signup and first successful API call. Developers get an API key, get distracted by other work, and never complete the integration. A targeted onboarding sequence can dramatically improve this: immediate welcome with a working code example, day-1 framework-specific guides, and a day-3 check-in asking if the integration worked.

The key insight is that different developers integrate at different speeds. Some complete integration in an hour. Others take weeks. Your onboarding sequence should be event-driven (triggered by what they have done) rather than time-driven (triggered by days since signup).

From Free API Consumer to Enterprise Customer

Your highest-value email automation identifies enterprise leads from API usage patterns. A developer making 10,000 API calls per day has built something significant on your platform. That is the moment to introduce enterprise features: higher rate limits, SLA guarantees, dedicated support, and custom endpoints.

Native payment integration (like Sequenzy with Stripe) makes this automatic. Usage events trigger enterprise identification sequences, and billing events track the conversion from free to enterprise.
