Every guest informed,
even when plans change at 6 pm.
The confirmation after signing up, the reminder the day before, the "we moved to room B" an hour before doors open: Unlimited Messaging sends them by WhatsApp, SMS and email, from your own number and address.

GeminiThe week before an event
A guest list, a venue, and a forecast that keeps changing
Unlimited Messaging lets an event organizer message guests by WhatsApp, SMS and email from their own number, mailbox and phone, and automate RSVP confirmations, day-before reminders and last-minute updates from a guest list or a ticketing tool.
Monday you chase the RSVPs that never came. Thursday the caterer needs final numbers. Friday it rains, the garden party moves indoors and 80 people need to know before they leave home. A newsletter tool sends a nice email that lands in Promotions; a WhatsApp group with 80 strangers turns into noise.
With Unlimited Messaging, each guest gets a personal message on the channel they read: WhatsApp first, SMS from your Android phone for those without it, and the full programme by email from your own address. One request can send all three. A new row in Google Sheets or an Eventbrite order can trigger the confirmation through n8n, and replies like "we'll be 3, not 2" land in one inbox.
Same idea for hotels confirming bookings and restaurants reminding guests. Texting from your own phone is explained on the SMS page.
What changes
What Unlimited Messaging changes for an event organizer
Guests hear from you personally, on the app they check, and a change of plan reaches everyone in one go.
Confirmations without copy-paste
With n8n, a new line in your Google Sheets guest list or a new Eventbrite order sends a personal confirmation with the date, place and a link to the programme.
One request, three channels
The same update can go by WhatsApp, SMS and email in a single API call or n8n step, so a guest who missed one still sees another.
Last-minute changes that land
Rain plan, new room, delayed start: send the change to the whole list from your own number, and read the "OK, thanks" replies in one inbox.
Your number, free to start
Link your WhatsApp by QR code, your mailbox over IMAP/SMTP and your SIM through the Android app. No per-message fee, on the free plan too.

Good to know
Good habits for a large guest list
Guests who signed up
Message people who registered or gave you their number for the event. Blasting a bought list from your WhatsApp gets the number banned, whatever the tool.
SMS for the few, WhatsApp for the many
Texts leave from your phone at about 30 every 30 minutes and count against your plan. For 200 guests, send by WhatsApp and keep SMS for those without it.
Attachments and branding need a paid plan
Free messages carry a short footer and are text only. Ticket PDFs, maps and photos as attachments, and footer-free messages, need Medium or Max.
