One passage, shaped for the platform you actually send from. GoHighLevel, Kit and Listmonk each need a different length and a different setup, and getting that wrong is worse than skipping it. In testing, treated mail landed in Promotions zero times out of forty. Untreated mail landed there twenty out of twenty.
GoHighLevel, Kit and Listmonk do not handle a broadcast the same way, so the setting that helps on one can hurt on another. Ghost Ink reads which one you send from and shapes the passage for it. Tell it the platform and it picks the rest.
| Platform | Passage length | Preheader | Why it differs |
|---|---|---|---|
 GoHighLevel |
1,200 - 3,500 words | Blank, added for you | Its broadcasts need the long form and their own preheader handling. |
 Kit |
270 - 340 words | None | Kit surfaces more of the message than GoHighLevel does, so short is correct here. |
 Listmonk |
270 - 340 words | None | Same short band, and template variables and links come through untouched. |
| Anything else | 270 - 340 words | None | Falls short rather than guessing. Short is the safe direction to be wrong in. |

Nothing about your offer, your list or your subject line changes. The visible email your reader sees is the one you wrote, and that is checked on every single send rather than assumed.
This isn't a prompt. It's the full kit that makes the AI treat your email correctly on the platform you actually send from, with the checks that stop it shipping something you did not approve.
A zero-dependency command line tool that runs on stock Node. Nothing to install and nothing to configure.
Written out in full, including the ones that are per platform. This is where most of the value sits, and it is the part people get wrong.
One model writes the passage in your voice, a second one judges it, and neither result reaches your email until both pass.
Run it on the message your platform actually built and it tells you whether the copy that shipped still reads the way it did when you approved it.
