Email copy generator that keeps the subject line honest
Email is the one channel where a deceptive subject line is specifically illegal in the US, and where a missing unsubscribe link is a regulator’s problem rather than a platform’s. This writes subject lines and body copy that match, and flags the parts that would not survive scrutiny.

Why this instead of a blank prompt
Subject and body that describe the same email
Subject lines are generated from the body, not bolted on. A subject that promises a discount the email does not contain is the specific thing CAN-SPAM calls deceptive, and it is the fastest way to train people to ignore you.
Preview text used as real estate
Most senders leave the preheader to be auto-filled with "View in browser". You get preview text written to extend the subject line instead of repeating it.
Compliance obligations you cannot generate away
The output reminds you what copy cannot solve: a valid physical postal address, a working opt-out process, accurate sender details, and the consent or other lawful basis required in each recipient’s jurisdiction. Those are sender obligations, not copy choices.
Three risks this catches, with the fix
These are the patterns that cause the most trouble on this channel. Every one of them reads like normal marketing language, which is exactly why they slip through.
Subject lines that misrepresent the content
Under CAN-SPAM a materially misleading subject line is a per-email violation. "Re:" and "Fwd:" on a message that is neither, or a discount in the subject that is not in the email, are the textbook examples.
- Flagged
- “Re: your order — 70% off inside!”
- Clean
- “The 1.7L kettle is back in stock”
Unsubstantiated claims that live forever in an inbox
Email is archived and forwarded. A health or earnings claim that would be flagged on a listing is more durable here, because the recipient still has it a year later when they want a refund.
- Flagged
- “Our customers typically double their revenue in 30 days”
- Clean
- “Read how one seller restructured their listings — with their numbers, shared with permission”
Pressure tactics and manufactured deadlines
Fake expiry dates and "last chance" messages sent weekly are deceptive practices, and they measurably increase spam complaints — which damages the sender reputation that determines whether your next email lands at all.
- Flagged
- “FINAL WARNING: your cart expires in 60 minutes!”
- Clean
- “Your basket is saved. The kettle is in stock if you still want it.”
The compliance engine runs against documented marketplace and advertising policies, and flags the known failure patterns before you publish — with the exact phrase and the rule that triggered each flag.
Compared with the alternatives
Three honest ways to get this written. We are comparing approaches rather than naming competitors, because a general-purpose chatbot is not trying to do this job and it would be unfair to score it as if it were.
| Capability | CopyForge AI | General AI chatbot | Writing it by hand |
|---|---|---|---|
| Grounded in facts you supply | Required — the prompt is built from your input and nothing else | Optional, and the model fills gaps with plausible invention | Yes, if you are disciplined |
| Policy check before publishing | Applicable checks from the 18-rule documented library, with the exact phrase flagged | None, unless you know to ask — and then it grades its own work | Only what you remember to check |
| Time for one email | Under a minute | A few minutes plus prompt fiddling | 30–90 minutes |
| Consistent brand voice and banned words | Brand profiles apply approved claims and forbidden words every run | Re-paste your guidelines every single time | Depends who wrote it |
| Doing a whole catalogue | Bulk CSV on paid plans, exported as a ZIP | One at a time, by hand | Weeks |
| Cost | Free for 10 a day; Pro is $19/mo for 2,000 per 30-day window | $0–20/mo, plus your time on prompts and checking | Your hourly rate, or a copywriter’s |
