Show HN: I added A/B testing to my cold email generator – does this add value?

I built ColdCopy (coldcopy.xyz) a few days ago to solve my own cold email writing struggles. Initially it just generated one personalized email, but I kept wondering "should this be more direct or more friendly?" So I added A/B testing - now it generates 3 versions (Professional, Friendly, Direct) side-by-side so you can compare and pick the best approach. Early users seem to like having options, but I'm curious if this is genuinely useful or just feature bloat. Does having multiple versions actually help with cold outreach, or does it create decision paralysis? The technical implementation was straightforward - same form data, three API calls with different prompt variations, display in a responsive grid. But I'm more interested in whether it solves a real problem. Built with Next.js 14 + OpenAI API. Currently free with daily limits. What do you think - is A/B testing for cold emails useful, or am I overthinking this?

I’m not a fan of cold emails in general so I would say no this does not provide value. I’m sure others have different opinions as it’s an important part of marketing.
