Case Study: Walcu achieves higher dealership sales and customer engagement with SendGrid

How Walcu brings next-level customer support to a classic industry

Walcu, an automotive CRM serving car dealerships in Spain, needed better ways to manage customer communications in an industry still reliant on landlines and missed-call logs. With SendGrid as part of its broader Twilio-based communication stack, Walcu set out to help dealers support customers across email, SMS, voice, and app notifications more effectively.

SendGrid helped Walcu build email capabilities for follow-up and marketing campaigns, while Walcu used the platform alongside other Twilio APIs to create an omnichannel experience. The impact was measurable: dealership email open rates rose from 20% to as high as 70%, dealerships handled about 100,000 calls and 50,000 text messages per month, and sales increased by as much as 15%.
