Double opt-in is a process where users need to confirm their phone number to be added to your SMS list and receive SMS communications. This double confirmation ensures their subscription to your subscriber base. Implementing double opt-in in SMS marketing is an effective way to maintain GDPR compliance and keep your subscriber list accurate and engaged.
