Mail merge was invented so you could type Dear [FIRSTNAME] once and print a thousand.
Most HOA letters are still made that way.
An estoppel has to know more than a name.
You know the file. ESTOPPEL_FINAL_v3_USE_THIS_ONE.docx, with the previous owner's name still sitting in the middle of it.
So the Letters studio starts where a word processor gives up.
Type a slash, pick a block: paragraph, heading, list, checklist, table, page break, a colored callout. Twenty block types, dragged by the handle, with comments on each other's drafts.
Beside it runs a live A4 preview, so the page you're looking at is the page that prints. No more discovering at PDF time that the signature block emigrated to page four, alone.
Then the part that matters.Type @ and you get about 35 merge tokens — owner, unit, association, ownership, date. Drop one mid-sentence and at render time it becomes that property's real data.
And you can preview the finished letter against a specific real unit, before it goes anywhere near a customer.
Two details we care about more than is probably healthy.
First: every token is fetched in one trip to the database, not one trip per token. We shipped the thirty-five-trips version first. It worked. It was also, briefly, the slowest letter ever produced by anybody.
Second: if a unit isn't yours, its tokens resolve to nothing.
Not a guess. Not a neighbor's balance. Nothing.Letters can also carry fillable fields sitting inside the prose rather than bolted on the end. Each one has a mode:
→ connected to data, filled automatically
→ the purchaser fills it
→ an admin fills it
→ or a party you name yourself fills it
The last two can pause an order. The flow stops, the field lands on someone's queue, and everything resumes the second it's answered. Nobody has to remember anything.
And yes, AI: draft the whole letter from a prompt, or select a paragraph and ask for "make this more formal", or "translate to Spanish".
A template that knows nothing about the property is a form letter.
A template that knows which house it's about is a document.Next: the one block a mail-merge tool can never have.
