Why SMS remains one of the most powerful — but most underutilized — channels in marketing.

For years, marketers have talked about the potential of SMS: high open rates, immediate visibility, and direct access to the device we all check 96 times a day. So why do most brands still treat SMS as an afterthought?

Because opt-ins are broken. And the way we collect phone numbers is even worse.

If you’ve built a strong email list, you’ve already done the hard part — capturing attention and building trust. But here’s where most brands leave value on the table: they stop at email, instead of using it to build a direct, real-time SMS list.

That’s where Whisp comes in.

With no short codes, no form fills, and zero friction, Whisp makes it easy to turn your email audience into a TCPA-compliant SMS list — using a landing page powered by our patented technology.

In the evolving landscape of digital marketing, businesses are continually seeking more effective ways to connect with their audience.
