The grade is rule-based and runs on the line you type. It starts at 100 and takes points off for length outside 2 to 6 words or over 45 characters, for phrases from the same 109-phrase list the spam word checker uses, for marketing markers (%, $, free, offer, sale), ALL-CAPS words, Title Case, exclamation marks, emoji, a fake "Re:" on a first email, and for a line with no merge field or no reason to open. A is 90 or more, F is under 60. The rewrites strip what cost points and keep your own words.
The idea lists use the trade names 67Leads carries and the offer angles from the cold email template generator. The angle counts are live from the warehouse.

No, and no tool can. Apple's Mail Privacy Protection loads messages on the user's behalf and stops senders from knowing when an email is opened, so open rates are inflated and unreliable (Apple, https://www.apple.com/newsroom/2021/06/apple-advances-its-privacy-leadership-with-ios-15-ipados-15-macos-monterey-and-watchos-8/, checked 4 Nov 2026). Judge a subject line by replies.
No. On a first email it pretends there was an earlier conversation. US law (CAN-SPAM) forbids misleading subject lines, and readers who notice stop trusting the rest.
Usually. Lower case looks like a note from a person; Title Case and capitals look like a newsletter. Keep proper names capitalized if you prefer.
Ones about the business itself: its name, its listing, a job type it does. Pick a trade above for 20 ready lines with merge fields that match the 67Leads CSV.
