How to set it up

WhatsApp Business API

Your own verified account. Lower cost per message, approved templates and your brand as the sender.

SMS via Twilio

For customers without WhatsApp or when WhatsApp fails. Automatic fallback: if the WhatsApp message isn't delivered, it tries SMS.

You control which channels are active for each type of notice, from a preferences screen for each account.

Why does it matter?

The reminder email ends up in spam. A phone call interrupts both the counter and the customer. WhatsApp reaches their pocket, it buzzes, it gets read. And because it goes through a verified API, it isn't a message from some suspicious 600-123-456 number: your business name appears.

Result: fewer late returns (between 30% and 50% according to our customers), fewer calls to the counter and customers who see you as more professional.

Frequently asked questions

Which plan includes it?

WhatsApp and SMS are included in the Business plan. You need your own WhatsApp Business API and/or Twilio account (you can start with SMS only).

How much does each message cost?

You pay Meta or Twilio directly. WhatsApp message ~€0.04, SMS in Spain ~€0.06. car-rent.es adds no mark-up.

Can customers opt out of receiving them?

Yes: they can unsubscribe in their notification preferences or directly in the WhatsApp conversation. We respect that.

What about internal emails to the team?

Yes. Internal operational alerts (inspections, cash discrepancies, late returns) reach the manager by email and, optionally, by WhatsApp.

The legal texts (legal notice, privacy policy and data processing agreement) are only available in Spanish, which is the binding version.
