SMS List Growth

Turn traditional media into measurable SMS sign-ups

Print ads, radio spots, and podcast sponsorships are notoriously hard to track. You run an ad in a magazine or sponsor a podcast episode, and you have no idea how many listeners actually acted on it. Traditional media asks audiences to "visit our website" — which requires remembering a URL, typing it in later, and completing a form. Most people never do it.

Text-to-join keywords solve this. Instead of asking listeners to remember a URL, you tell them to text a keyword to a short code. They pull out their phone and do it immediately. The action is instant, the attribution is direct, and the conversion is frictionless.

How most brands try to drive action from traditional media

The standard call-to-action: a print ad says "Visit brandname.com/offer" or a podcast host reads "Go to brandname.com/podcast to claim your discount." The listener or reader has to remember the URL, type it in later (if they remember at all), navigate to a landing page, fill out a form, and submit.

Each step is a drop-off point. The reader forgets the URL before they finish the article. The podcast listener is driving or working out and can't write it down. The radio listener hears the URL once and it's gone. Even those who do remember the URL often abandon the landing page form because it's too many fields or the mobile experience is clunky.

The result: most traditional media campaigns generate brand awareness but very little measurable action. You spent money on the ad or sponsorship, but you have no way to know how many people it actually converted into subscribers or customers.

Text-to-join keywords for instant, attributable sign-ups

With AudienceTap, your print ad, radio spot, or podcast read includes a simple instruction: "Text FRESH to 55444." The reader or listener pulls out their phone, sends the text, and is instantly subscribed. No URL to remember, no form to fill out, no website to visit.

The keyword is short, memorable, and actionable. "FRESH" is easier to remember than "brandname.com/fresh-coffee-offer." And because the action happens via text, the listener or reader can do it immediately — while reading the magazine, listening to the podcast, or sitting in traffic hearing the radio spot.

Best of all, attribution is crystal clear. Each campaign gets a unique keyword. Your magazine ad uses "Text COFFEE to 55444." Your podcast sponsorship uses "Text ROAST to 55444." You know exactly how many subscribers each channel drove — and you can track the revenue those subscribers generate over time.
