Both phone number and email validation use a one-time passcode to verify that fans are providing real contact information rather than fake entries like 'test12345@gmail.com.' However, phone number validation provides a significantly smoother user experience. On most smartphones, when a one-time passcode arrives via SMS, it automatically populates without the fan ever leaving the activation URL. With email validation, fans must leave the webpage, open their email app, refresh their inbox, memorize the code, return to the browser, and type it in — a process that introduces friction and potential for error. Based on client feedback, we strongly recommend phone number validation for the cleanest fan experience, reserving email validation only for cases where a sponsor specifically requires building an email list.
