As speaking 1:1 with a brand becomes the standard experience for a customer, adding your number to your packaging is a no-brainer. You can either add your unique Blueprint number (found on your Blueprint Dashboard) as a full number or add a simple QR code for customers to scan and message your brand directly. This also blurs the lines between offline activations and online acquisition.
Add your number or QR code to your external eCommerce packaging too, not just the product itself. This can help to build your audience from external sources, like Amazon, by offering a way for a customer to join your owned SMS community.
