Open-letter ad
A full-page open-letter advertisement: AN OPEN LETTER over a huge serif salutation (to every parent in the neighbourhood), a drop-capped letter and a handwritten signature in the brand's name — a public promise, apology or stand taken in print.

When the AI picks it
MarketiQ’s Creative Director favours the Open-letter ad for posts that start a conversation, announce news or prove a point, when the message is a story or one sharp insight. It is built first to start a conversation.
It reads each post’s goal and shape first, then its own words, the platform and the facts you have, and offers this template only where it fits.
Who it’s for
Any business. Nothing in it assumes what you sell, so the Director can offer it to a software company, a café or a coaching centre alike — whenever the post fits.

Single image. Each size is laid out for its canvas, not cropped; the sample above is the 4:5 version.
What it needs
Only your post. It is made from your copy and your brand kit — there is nothing else to prepare.
Rules the AI follows
Word for word from the template library. The Director follows the copy rules when it writes into the template, and the visual review checks every creative against the visual rules.
Copy rules
- A sincere public letter in the first person plural: what the brand commits to, owns up to or stands for.
- Signed by the brand, or by a real person the post names; every fact comes from the post.
Visual rules
- A paper page boxed by a heavy black border like a full-page ad: AN OPEN LETTER in spaced mono caps, the salutation huge in a black serif, a double rule.
- The letter in serif with a large drop cap (two columns on 16:9), then a closing line, a handwritten signature in the brand colour, and the logo with the website on the right.
