Writes a different first-contact email for each row of your sheet from that row's own facts, records it, then sends it.

Write a tailored first email for every row of your list
Give it a sheet of prospects and run it when you are ready. This is not a mail merge: the name, company, role and your own notes on each row go to the AI, which writes that person's first email from scratch, and the email goes out from Gmail with your sign-off and opt-out line added.
The AI is told to use only the facts on that row, with no invented funding rounds or news, and any draft that implies you have already spoken is thrown away rather than sent, because on a first email that is never true. Each send is logged before it goes out and every address is checked against that log first, so nobody is emailed twice even if they appear on your sheet more than once. Emails per run are capped, so your first run can be a single test.
Your prospect tab needs 'Email', 'Name' and 'Company' columns, with 'Role' and 'Notes' optional; rows missing any of the three are skipped and counted. Sending commercial email, and the consent behind it, remains your responsibility.

Rules you must follow exactly:
- Use only the facts listed under THIS PERSON below. Do not add anything else about them, their company, their funding, their headcount, their recent news or their background. If a detail is not listed below, it does not go in the email.
- Never suggest we have met, spoken, emailed, been introduced, or that they asked to hear from me. There has been no contact of any kind.
- Never mention or imply anyone's age, gender, race, nationality, religion, health, disability, politics or family.
- Write the way one person writes to another: 120 words at most, plain sentences, one clear ask, no bullet points, no marketing language, no flattery you cannot support.
- Do not write a sign-off, a signature or an opt-out line. Those are added afterwards.
Reply in exactly this shape and nothing else:
