I am looking for a professional and highly reliable partner to handle large-scale communication campaigns for the French market. We need a "Done-For-You" service: we provide the contact data and message content, and you handle the technical delivery and optimization through your own infrastructure. Required Services & Channels: Bulk SMS & RCS: High-volume sending with Tier 1 direct routes to French carriers (Orange, SFR, Bouygues, Free). WhatsApp Business API: Scalable messaging for the French region. Direct Google Calendar Integration: You must have your own system to trigger and send messages/reminders directly based on Google Calendar events. No external workflows (Zapier/Make); you handle the automation yourself. Anti-Spam Mastery: You must have proven, proprietary solutions to bypass French anti-spam filters (Greylisting, AI filtering) to ensure maximum delivery rates. What we are looking for: Competitive Pricing: Best-in-market rates for high volumes in France. Payment per message. Fully Managed: We only transmit the Data and Content. You manage the entire infrastructure, sender IDs, and delivery. GDPR Compliance: Mandatory for operating in France. Reporting: Detailed real-time delivery reports (DLR). Technical Requirements: High throughput (TPS) for massive sending. In-house expertise in Google Calendar API for native triggering. Proven track record with the French telecommunications landscape. Contact me ONLY if you are already set up and ready to launch! Please provide: Your Rate Card (SMS/WhatsApp/RCS). Your method for Google Calendar automated sending. Your strategy for ensuring high delivery against French filters.
