Rayo SMS is a full-featured Web-to-SMS Software-as-a-Service (SaaS) platform designed for businesses, developers, and white-label resellers. Whether you need to send bulk promotional campaigns from your browser or trigger time-sensitive transactional alerts from your backend systems, Rayo SMS provides a reliable, privacy-first workflow.
Bulk Marketing SMS
Organize recipients into Groups and send targeted campaigns to thousands of numbers at once. Duplicate mobile numbers across selected groups automatically receive the message only once, and contacts marked as Invalid are suppressed automatically.
Transactional & Scheduled SMS
Dispatch instant order confirmations, appointment reminders, and one-time passwords (OTPs), or schedule messages for future delivery with full visibility and cancellation controls.
GDPR-Ready Message Masking
Protect sensitive customer data by permanently replacing sent message bodies with ****** either on demand, immediately after delivery, or automatically after a configurable number of minutes.
Developer API & Webhooks
Integrate SMS capabilities into any application via the HTTP API (https://api.rayosms.nl/v1), manage up to 25 independent API keys, test with zero-cost Simulation Mode, and receive signed delivery webhooks.
Team Collaboration
Invite developers to your account with dedicated role-based permissions so they can manage API keys and webhook callbacks without accessing billing or marketing campaigns.
White-Label SaaS
Launch and operate your own branded SMS platform under your own domain and logo, connect your own Stripe and bank accounts, and manage your customer base.
