I’m not ready to start using SMS, but I want to start collecting consent. Is that okay?
Klaviyo will not store consent until SMS is enabled, so you must set up SMS before you can begin collecting consent.
We don’t recommend collecting SMS consent until you are ready to set a welcome flow live. It is a best practice to thank people when they subscribe — particularly when users are giving you something as personal as their phone number. Further, if you hold off on sending any communications, it can lead to a strange user experience. For instance, the subscriber may get their first text from your brand (an unrecognized phone number) months later and not remember that they signed up.
