When to use WhatsApp in SaaS onboarding
WhatsApp does not replace email in SaaS onboarding: it complements it. Use email for long documentation, PDF guides, verification links. Use WhatsApp for critical behavioral nudges: 'Have you completed setup?' at 24 hours if setup was not completed, 'Have you sent your first message?' after 48 hours if the core action was not taken.
The WhatsApp channel is particularly effective for blocking moments: when product analytics shows a user stopped at a specific setup point, a proactive WhatsApp message converts significantly.
Onboarding sequence for an API product
A WhatsApp onboarding sequence might be: Day 0: welcome message with link to documentation and sandbox. Day 1: 'Found your API credentials?' Day 3: 'Integrated your first webhook?' Day 7: 'First message sent? Now try templates.'
Each message has a single objective and single CTA. Do not try to do too much in one message.
Success metrics for WhatsApp onboarding
Measure WhatsApp onboarding impact on three metrics: time-to-first-value, activation rate, and 30-day retention. Compare these metrics between email-only users and email-plus-WhatsApp users to calculate the incremental value.
