Should I mention sustainability in recovery messages?

As an e-commerce brand in the sustainable fashion space, I've been wrestling with how authentic and strategic sustainability messaging can be during customer recovery communications. Our brand has invested heavily in ethical production, using recycled materials and ensuring fair labor practices. But I'm torn about whether these values resonate during cart abandonment or post-purchase recovery messages. Are customers truly motivated by sustainability claims when they're on the fence about a purchase? Or do they see it as generic marketing noise? We've noticed our conversion rates are decent but not exceptional, and I'm wondering if our messaging is hitting the right emotional triggers. Our product margins are tight, so every interaction needs to count. I want to craft recovery messages that not only bring customers back but also reinforce our brand's genuine commitment to sustainability without sounding preachy or disconnected from the immediate purchasing decision. The challenge is striking that delicate balance between compelling commercial messaging and our deeper environmental mission. How can we use sustainability as a genuine conversion lever rather than just another buzzword?
