MOBILE OPT-IN SIMPLIFIED™

Loyalty starts with the opt-in.

You already have a customer list. But if they haven’t opted into SMS, they may as well not exist. Whisp gives you the missing piece — a fast, frictionless opt-in — so you can finally make SMS and Mobile Wallet your most powerful loyalty channels.

Why the Opt-in is the Only Thing That Matters

1 million customer numbers ≠ 1 million reachable customers

SMS has 98% open rates — but only if they’ve opted in

Whisp gives you the legal opt-in your CRM is missing
