Quick Answer

E-commerce messaging is automated SMS, WhatsApp and RCS sent by online stores at each step of the buyer journey: login OTP, order confirmation, payment links, shipping updates, COD confirmation, abandoned cart reminders and feedback. SMSGatewayHub provides APIs, a WooCommerce plugin and DLT-compliant routes, with Pay As You Go pricing and billing only for delivered messages.

Why does every online store need automated messaging?

Online shoppers expect instant confirmation and constant visibility. SMSGatewayHub makes it possible to improve every interaction, from order placement and tracking updates to marketing and feedback campaigns. Add web URLs to payment links, invoices and landing pages, and measure campaign impact in real time to optimise your mobile marketing.

The core building blocks are OTP SMS for sign-up, login and COD verification; transactional and service SMS for order and shipping alerts; and promotional SMS, WhatsApp and RCS for deals and cart recovery.

The e-commerce order messaging workflow

  1. Sign-up and login

    OTP verifies the customer's mobile number at registration or checkout.

  2. Order placed

    An SMS or WhatsApp message confirms items, amount and order ID with a link to the invoice.

  3. COD confirmation

    For cash-on-delivery, ask the customer to confirm by reply, link or missed call before dispatch to reduce returns.

  4. Shipped and out for delivery

    Tracking link and delivery window go out automatically from your store or shipping partner events.

  5. Delivered and feedback

    A delivery confirmation is followed by a mobile-optimised review or survey link.

Frequently Asked Questions

Most stores send OTPs at sign-up and checkout, order confirmations, payment links, shipping and out-for-delivery updates, delivery confirmations, abandoned cart reminders and feedback requests. SMSGatewayHub supports all of these through APIs and its WooCommerce plugin.

Yes. Order and shipping updates registered as Service Implicit templates on DLT are delivered to DND numbers because the customer has an active transaction. Promotional deals are not delivered to customers who blocked that category.

Your store detects a cart left without checkout and calls the SMSGatewayHub API to send a reminder with a payment or cart link. Send it as a service message only where you have the customer's consent; otherwise use a promotional template within permitted hours.

Yes. SMSGatewayHub offers a WordPress WooCommerce Pro SMS plugin that sends SMS on WooCommerce events and adds features such as scheduled SMS, login with mobile and two-factor authentication. Custom stores can use the HTTP API instead.

Ask customers to confirm COD orders before dispatch by replying to an SMS, clicking a link, entering an OTP or giving a missed call. SMSGatewayHub provides SMS, OTP and missed call services for each method.
