Keep customers informed at every step of their journey. From order confirmation to delivery updates, OneSend2U lets you send transactional and promotional messages across SMS, Email, and WhatsApp — through the providers that deliver best in each market.
Every customer touchpoint is an opportunity to build trust and drive revenue. OneSend2U handles the messaging patterns that power modern e-commerce.
Automate notifications for every stage: order confirmed, payment received, shipped, out for delivery, and delivered. Use templates with dynamic variables for order IDs, tracking links, and estimated delivery times.
Recover lost revenue with multi-channel abandoned cart reminders. Reach shoppers on WhatsApp, Email and SMS from a single API call — the platform renders one template per channel and routes each through your chosen provider.
Launch flash sales, seasonal promotions, and personalized offers across channels. Use country-specific providers for the best delivery rates and track campaign performance with per-message cost visibility.
Trigger automated messages for support ticket updates, return confirmations, refund processing, and satisfaction surveys. Keep customers informed without manual intervention from your support team.
Pick the channel your customer actually reads. OneSend2U renders the same template for WhatsApp, Email or SMS depending on consent and availability.

E-commerce businesses need messaging that scales with their growth, reaches customers on their preferred channels, and does not break the budget.
Reach customers on SMS, Email, and WhatsApp from a single API call. No need to maintain separate integrations for each channel. Define channel preferences per notification type and let the platform handle the routing.
Create, version, and manage message templates per channel, language, and country. Use dynamic variables for order details, customer names, and tracking information. Promote templates through a controlled deployment pipeline.
Track per-message costs across every provider and channel. Use that visibility to configure the right provider per region and route each region through the provider you choose.
Handle Black Friday peaks and seasonal surges without breaking a sweat. Queue-based asynchronous processing ensures your messages are delivered even under extreme load. No capacity planning required.
