GeminiA landlord's month
Twelve units, three channels, and the same questions every week
Unlimited Messaging lets landlords, property managers and short-term rental hosts send rent reminders, check-in instructions and maintenance visit notices by WhatsApp, SMS or email, from their own number and mailbox. The free plan has no per-message fee; photos and PDF attachments need a paid plan.
Rent is due on the 1st. On the 5th you check the bank account and text the two tenants who have not paid, carefully, because you will see them on the stairs. On Friday a guest lands at 11 pm and asks for the key box code. On Tuesday the plumber needs access to flat 3, and the tenant must know before he rings.
With Unlimited Messaging, n8n reads your lease sheet and, on the date you choose, sends a courteous reminder to tenants whose payment is not ticked. The day before an arrival, guests get the address, key box and Wi-Fi details on WhatsApp. Visit notices leave by email from your own address, which leaves a written trace, with a text the day before. Claude or ChatGPT drafts the replies you would rather not write.
The same approach works for hotels and guesthouses and for real estate agents. How the WhatsApp link works is on the WhatsApp page.
What changes
What Unlimited Messaging changes for a landlord or host
Your tenants keep writing to the number they know. You stop typing the same message twelve times.
Rent reminders that stay courteous
On the date you set, n8n checks your lease sheet and texts only the tenants whose payment is missing. The tone is yours, and nobody who paid gets a reminder by mistake.
Check-in details before they ask
The day before arrival, the guest gets the address, key box code, Wi-Fi and checkout time on WhatsApp. Late-night "how do I get in?" messages become rare.
Visits announced in writing
Maintenance or inspection visits leave by email from your own address, with the date, the reason and the contractor's name, followed by a text reminder the day before.
One inbox for every unit
WhatsApp, SMS and email replies from all tenants and guests land in one list. Claude or ChatGPT can read a thread and draft the answer you approve.

Good to know
Rules worth knowing before you automate
Airbnb guests: payments stay on Airbnb
Airbnb requires every message before booking to stay on its platform and forbids asking guests to pay outside it. Use WhatsApp for practical details once the booking is confirmed.
Rent receipts in France
A landlord must send a free rent receipt to a tenant who asks, and can send it electronically only with the tenant's express agreement (article 21 of the 1989 law). PDF attachments by email are on paid plans, from Medium at €19 a month.
A reminder is not a formal notice
A friendly message does not replace the formal steps for unpaid rent, which follow your country's rules, often a registered letter or a bailiff. Check them with a professional.
When property software fits better
Unlimited Messaging sends and receives messages. For bookkeeping, bank matching or a channel manager across rental platforms, use dedicated software, and connect it through n8n.
