Lleida.net sent more than one million certified notifications in September 2026 through its certified email and Openum services. Certified email converts messages from Gmail, Outlook or other email clients into legally valid electronic notifications, while Openum certifies the delivery, opening, content and integrity of documents sent by email, SMS or WhatsApp. Both services use Lleida.net technology protected by its patents. Certified email is used to prove the required attempt at prior negotiation under Spain's Organic Law 1/2025, which has been in force since April 3, 2025. The company ended June with a record 12,545 active customers.
