I'm experimenting with keeping in touch with special offers, shipping follow-ups, and general customer service through SMS messaging. I'm not really sure what it's all about. I won't blow up your phone with messages, I promise, and you can opt out at any time. The app I'm using is Postscript, and they say to include the following in my Terms of Service:

In addition, you agree to our Messaging Terms (https://terms.pscr.pt/legal/shop/susannah-carson/terms_of_service) and Messaging Privacy Policy (https://terms.pscr.pt/legal/shop/susannah-carson/privacy_policy).
