alexrony21/Gmail-Email-Validator ? reverse-engineered prompt

Build me a Gmail email validator tool that can take a big list of email addresses and quickly tell me which ones are valid, which ones are not, and which ones look risky or uncertain. I want it to be really fast, able to check many emails at once, and not require me to set up proxies. It should work smoothly without getting stuck on captcha problems, and it should feel reliable for large lists, not just a few addresses.

Please make the interface simple so I can paste in emails or upload a list, start the check, and then see clean results I can export. If you need to look up current docs online to make the checks more accurate, go ahead. I also want the results to be clear enough for marketing or business use, with a basic summary of how many were good, bad, or uncertain.
