How can I encourage my customers to opt for sustainable shipping options?

Educating your customers on the importance of using sustainable options should be your first step. Once they see the reason, making the decision becomes a lot easier. To do this you can make use of blogs, social media, or any other means to share the message.

That said, I understand that some people seem not to care, in which case you will need to offer an alternative incentive. This could come in the form of discounts, or future deals.

You'll also want to clearly point out the benefits of using the sustainable option, while clearly and transparently explaining the fees (and what they are used for).

Options such as custom package personalization can also sway a customer to take the sustainable route, as they feel they have more control over their product.
