Recipe: write your monthly customer newsletter

Collect the month's news in a few lines. Hermes turns them into a friendly newsletter email in European Portuguese, with three subject lines to choose from, saved in a file.
Time needed 5 minutes
You need A Hermes agent connected to an AI model and a short list of this month's news (new products, dates, opening hours...)
Result A newsletter ready to paste into your email tool, and 3 subject line options

1. List the news

One line per news item, with the exact dates and prices. Upload the list in FILES → workspace (see Hermes reads a contract for you) or paste it in the chat.

Our test list, newsletter-news.txt:

News for the December newsletter - Sunrise Bakery

- Christmas orders open on 1 December: bolo-rei, bolo-rainha and broas. Order by 20 December, pick up 23 or 24 December.
- New product: sourdough rye bread, 4.20 EUR, on sale from 2 December.
- Opening hours over the holidays: 24 December 07:00-15:00; closed 25 December and 1 January; 31 December 07:00-15:00.
- Our baker Rui won 2nd place in the regional custard tart contest (Porto, November 2026).
- Loyalty card: from 1 December, the 10th coffee is free.

2. Ask for the newsletter

In CHAT we wrote:

Read workspace/newsletter-news.txt. Write our December customer newsletter (email) in European Portuguese: a friendly intro, one short paragraph per news item, and a closing line. Use only the facts in the file. Give me 3 subject line options. Save it as workspace/newsletter-december.md.

Hermes writes the newsletter

  1. The newsletter: a short intro, one paragraph per news item with a title, the holiday hours as a list, and a closing line.
  2. Three subject lines to choose from, for example Bolo-rei, broas e um pão novo: as novidades de dezembro.
  3. Hermes tells you what is missing and what it assumed: the notes do not say how to place a Christmas order (so the newsletter does not either), and it signed with the name used earlier in the chat.

The file newsletter-december.md in FILES → workspace has the subject lines at the top and the email text below, ready to copy.

Check that it worked

We compared the newsletter with the list. All five news items are there, and every date, price and time is correct: orders from 1 to 20 December, pick-up on 23 or 24, rye bread at 4,20 € from 2 December, the four holiday dates, Rui's 2nd place, and the 10th coffee free from 1 December. Hermes added only friendly words ("o cheiro a Natal já se sente"), no new facts.

The point Hermes raised is a real gap: a customer who reads "já pode encomendar" will want to know how (in the shop, by phone?). Add it to your list and ask again.

Make it yours

  • "Add a line: orders by phone or in the shop, and give our phone number." (write your real number in the message)
  • "Make an English version for our foreign customers."
  • "Make it shorter, for a WhatsApp broadcast."
  • Every month: keep a running list of news in the file and ask on the last day of the month (see Schedule a recurring task to be reminded).

Common problems

Hermes invented a promotion or a date

Say "use only the facts in the file", as we did, and check every number before you send. Remove anything you did not write in your list.

The tone is not right

Tell Hermes what you want: "More formal, we write 'Caro cliente'", or "Shorter sentences, no exclamation marks."

Can Hermes send the newsletter?

In this recipe Hermes only writes it. Paste the text into the email tool you already use for your customers (it handles the mailing list and unsubscribe links).
