How do I get user consent for WhatsApp before they sign up?

Add a checkbox at signup ('I'd like updates on WhatsApp'). Pre-checked is risky — keep it opt-in. Sendvise stores the consent record with timestamp + IP for compliance.

Will my Gmail-heavy users actually use WhatsApp for product updates?

Indian SaaS users: yes — 91% open rate on WhatsApp vs. 15% on email. International users: depends on geography. Sendvise lets you split traffic by country.

Can I trigger flows from my product (e.g., user activates feature X)?

Yes — every product event you fire (Mixpanel, Segment, your own DB) can trigger a Sendvise flow. Webhooks, Segment.io destination, or REST API.

How is this different from Intercom / Customer.io?

Those tools optimise for email + in-app. Sendvise is WhatsApp-native: official Meta API, India-first conversation pricing, Hindi/regional language support, and Indian-time SLA. Most SaaS startups use both — Sendvise for WhatsApp, Intercom/Customer.io for email/in-app.

Can I A/B test onboarding sequences?

Yes. Drop an A/B split block in the flow. Sendvise tracks per-arm activation lift and auto-promotes the winner after stat-sig.

Pain points

Challenges saas & startups brands actually face

We've heard these from 100s of operators. Sendvise is built around them.

Onboarding emails ignored
Day-1 'welcome' email opens at 15%. Users never reach activation. Activation drop-off kills LTV.
Churn signals spotted too late
User logs in once, then disappears. By the time you notice, they've already cancelled. Win-back is too costly.
Support tickets pile up at scale
Same questions, again and again. Engineers get pulled into support. Velocity tanks.
