Quick check for decision makers
Appointment management with AI support.
Appointment reminders via WhatsApp with 70 to 95% open rate. No getting lost in the inbox.
armincx syncs appointments from Google Calendar and sends configurable WhatsApp reminders (e.g. 24 hours and 1 hour before). Recipients can confirm or cancel directly via WhatsApp. Messages are delivered through the official WhatsApp Business API and require prior opt-in.
Send follow-up messages automatically after appointments. Share next steps or collect feedback.
After a Google Calendar event ends, armincx automatically triggers a WhatsApp message. Content is freely configurable: thank-you message, summary of next steps, link to a feedback form, or an offer. Timing is flexible (e.g. 1 hour or 1 day after the appointment).
WhatsApp reminders significantly reduce no-shows. Especially effective in B2B sales with demo appointments.
Email reminders have an open rate of 20 to 40%. WhatsApp sits at 70 to 95%. This means the reminder actually gets read. Additionally, the response barrier is lower: a quick confirmation via WhatsApp is easier than opening an email and clicking a button.
The Google Calendar integration connects your appointment scheduling with armincx customer service. Calendar events from Google Calendar become available in armincx and can automatically trigger actions: reminders via WhatsApp, booking confirmations, and follow-ups after appointments.
The integration is primarily designed for businesses with appointment-based models. This includes B2B sales teams with demo scheduling processes, service providers with consulting appointments, and e-commerce brands that offer personal consultations (e.g. interior design, fashion consulting, custom products).
The integration solves a specific problem: no-shows at booked appointments. When your sales team regularly books demos or consultation calls and prospects fail to show up, it costs time and revenue.
WhatsApp reminders have an open rate of 70 to 95% compared to 20 to 40% for email reminders. This means your appointment reminder actually gets read. In practice, this leads to a significant reduction in no-show rates.
Typical use cases:
armincx connects to your calendar via the Google Calendar API. New appointments, changes, and cancellations are automatically synchronized. Based on these events, workflows can be triggered in armincx.
Specifically, the following automations are available:
All WhatsApp messages run through the official WhatsApp Business API. Professional communication with opt-in, not informal messaging.
WhatsApp reminders before every appointment. Configurable timing and content.
Automatic message after the appointment with next steps, feedback link, or offer.
As soon as an appointment is booked, the participant receives a WhatsApp confirmation.
The core argument for the Google Calendar integration is no-show reduction. Email appointment reminders are often overlooked or end up in spam. WhatsApp reminders reach the recipient directly on the device they use all day.
For B2B sales teams, every no-show means lost selling time. If a sales team books 20 demos per week and the no-show rate drops from 25% to 10%, that is 3 additional demos conducted per week. Over a month, that adds up to 12 additional conversations.
WhatsApp reminders work especially well because recipients can reply directly. A quick confirmation or cancellation via WhatsApp is significantly lower-friction than opening an email and clicking a link.

armincx works with flat-rate pricing without seat costs. The Google Calendar integration is included in the armincx package. For WhatsApp messages, official Meta fees apply.
11 cents per message is the official Meta fee for marketing messages in Germany. In Austria and Switzerland it is approximately 5 cents (as of 2026). WhatsApp messages generate 2 to 3x higher revenue per recipient than emails. After deducting the 11 cent Meta fee, you still have 139% higher net margin per contact compared to email.
For appointment reminders, the ROI is even more direct: every prevented no-show is a conducted conversation. In B2B sales, a single saved appointment is often worth hundreds or thousands of euros.
Your dedicated Customer Success Manager configures the Google Calendar integration and sets up the workflows.
Time to live: a few days, as the integration is technically straightforward.

Important: WhatsApp reminders require a separate WhatsApp opt-in from the recipient. The opt-in can be collected via booking forms, checkout pages, or dedicated opt-in flows.
The Google Calendar integration is a B2B supplement to the core armincx product portfolio. While most armincx integrations focus on e-commerce customer service (WISMO, returns, cancellations), Google Calendar addresses a specific B2B topic: appointment management and sales support.
For e-commerce brands with a consulting component (e.g. interior design, custom products, premium fashion), the integration also provides value. Customers who book a personal consultation receive a WhatsApp confirmation and reminder. This increases commitment and reduces appointment dropoffs.
