I filter email security scanners out of my analytics Safe Links, Mimecast and friends open every URL in an email before a human ever sees it. So I matched "outlook" in the user agent. Obviously a scanner.
I have used a few products to vibe-code my applications. The first one I used was Chatgpt. From this, I created my first application and it had a very average UI. I was using nextjs for frontend and backend, so for me, the backend part took time but it was decent. The second product which is good enough for me currently is Gemini. This creates a very good UI and backend at the same time. The first time I used it, it was a super upgrade in the UI. I also used Lovable to create one practice project, but I don't know why I did not used again.
I also heard people's suggestion of using different AI's like claude, cursor etc. but moving in to a different platform has some friction. What AI is most used or easiest to build an application? I recently heard of a new AI called Emergent, which creates the whole application with a single prompt.
Every proposal tool reports opens. Most of that number is link scanners, and "was it opened" was never the real question.
Closewatch scores each proposal and shows its work: "forwarded to someone else", "3m 51s on pricing", "came back on a later day". The dashboard is a call list, not a stats page.
Scanners are filtered out and only visible reading time counts. One link per recipient, so a second reader means it reached the person who signs.
It's the PDF you already send.
