Stop losing bookings. Start converting visitors into customers — instantly.
Caldarella Inquiry Form with Calendar Sync is a professional WordPress plugin that creates beautiful, responsive contact forms with dual delivery: every submission is sent to WhatsApp AND Email simultaneously. Perfect for vacation rentals, hotels, professional studios, restaurants, and any business that uses WhatsApp for customer communication.
What makes this plugin different?
Unlike generic contact forms, this plugin was built specifically for businesses that need real-time communication. When a visitor fills out your form, two things happen at once: you get an email notification (with Reply-To set to the visitor, so you can reply directly), and WhatsApp opens with a pre-formatted message ready to send. No delays, no lost leads.
For vacation rentals and hospitality businesses, the plugin includes full iCal calendar synchronization. Connect your Booking.com, Airbnb, and VRBO calendars — the form automatically blocks dates that are already booked. Visitors can only select available dates, eliminating double-booking inquiries.
FEATURES
🔀 Dual Channel Delivery
Every form submission triggers both a WhatsApp message and an email notification. Reply-To is automatically set to the visitor’s email — when you hit “Reply”, it goes directly to them.
📅 iCal Calendar Sync
Automatic synchronization with Booking.com, Airbnb, and VRBO. Booked dates are blocked in real-time. Checkout-only turnover days are handled correctly. Configurable sync intervals from 15 minutes to 12 hours.
📱 Mobile-First Custom Calendar
No browser-native date picker dependency. The custom calendar with blocked dates works identically on desktop and mobile. Visitors see available dates (green), occupied dates (red, crossed out), and turnover days (half/half).
👥 Multi-Contact Support
Add multiple WhatsApp numbers with names and roles. When more than one is active, the form shows a dropdown selector. Each contact can be filtered via shortcode.
📧 Multi-Email Notifications
Send notifications to multiple email addresses. Each recipient receives an individual email (no CC leaks). All with Reply-To set to the visitor.
