Depending on what you’re selling and who you’re marketing to, you might answer that question in a number of different ways. For example, if bug-free software is a big deal to your potential customers, you may want to focus on how fine-tuned your software is. You might want to include a section about your support team, how many users you have, how you handle errors…you get the idea.
There’s a better solution: Build out an automated email follow-up campaign that speaks directly to this objection. Any time you encounter this problem, you can send that prospect information that seems designed just for them. A multi-month educational campaign may reduce their content anxiety and nurture them toward a sale. Yes, it’s work up front, but once finished, this campaign will work for you always.
