The words first.
You say what it is about. FrankKi handles wording, structure and form.
Then the paper.
Your letter is printed, enveloped and delivered by post. Local tariffs across DACH (DE, AT, CH) and several European countries (FR, NL, GB, BE, LU, ES), and typically 4 to 18 business days to the rest of the world.
And the receipt.
When a deadline is involved, "sent" is not enough. Three features for that, clearly separated.
Standard letters have no tracking number. Real tracking with proof of delivery comes with a registered letter.
Three steps, one letter in a letterbox.
From the first sentence to the mailing takes a few minutes.
