Congrats on the launch, and welcome to HN. This is a real problem and it is good to see more teams taking it seriously. For a bit of context, and full disclosure that I am on the other side of this market: we built Beefree SDK around almost exactly this use case about ten years ago. We started with an embeddable email editor and expanded into popups and web pages over time, so the pain points you describe, Outlook quirks, merge tags, exports, versioning, localization, plus many others like security, scale, and collaborative editing, are all very familiar to us. I am not saying this to rain on your parade. The category has been maturing for a while now and there is genuinely room for good products in it. Honestly, HN was a big part of how we got off the ground in the early days. A launch post (https://news.ycombinator.com/item?id=8474744) is a lot of why we were able to grow and develop at all, so I have real appreciation for founders sharing their work here. Happy to compare notes any time.
