Thank you for the flagging this to me @JohnW0157 ! I had thought we had someone update this post already and must have missed it.
The SMS Marketing feature is out now to 100% of eligible accounts! This feature will only be available to customers within the US at this time because a valid Employee ID Number (EIN) is required in order to register the phone number.
Since this feature is implemented, we will be locking this thread per our standard process. If you have any questions about the SMS feature or how it works, feel free to start a new post or message me directly through my profile.
