A Comparison of Email vs. SMS Verification > 자유게시판

When it comes to confirming user ownership of contact details, businesses often choose between email-based authentication and SMS verification. Both methods serve the same basic purpose—to validate user identity—but they differ in how they work, how secure they are, and what kind of customer journey they provide.

Email verification typically involves sending a confirmation link to the user’s email address. The user must check their inbox, locate the verification email, and follow the URL to complete the process. This method is widely used because it’s free, simple to integrate, and works without a smartphone. It also helps ensure that users have a legitimate and active email account, which can be valuable for marketing. However, email verification can be slow. People may delay opening emails, or the message might get filtered out. This can frustrate users who want instant account activation.

This method is more timely and direct than email because most people check their text messages right away.

Top apps offer hybrid authentication, giving users a option or offering mobile OTP as secondary if verification is delayed. This dual-channel strategy can improve completion rates. Ultimately, the optimal method depends on the business environment. For services where identity assurance is paramount—like two-factor authentication—mobile OTP is standard. For sign-up processes where ease of use and affordability matter most, email verification is ideal.
