An unexpected delivery delay can be costly: squeezed margins, broken SLAs, overwhelmed customer service, and negative reviews that hurt your sales. The good news: a simple notification about a delivery delay via text message, email, push notification, or RCS can turn a bad experience into a demonstration of professionalism.
Well-designed notification processes integrated with your TMS/WMS 2, help prevent delays, enable real-time adjustments, and reduce the volume of claims. This is exactly what a multichannel communication platform like Docoon—a specialist in transactional messaging and the management of alerts and critical data flows—enables. Here’s how…
Why Delivery Delays Are Driving Up Your Costs
Delays: A Direct Threat to Your SLAs
In e-commerce, a delay isn’t just an operational issue— it’s a breach of the implicit contract with your customers and marketplaces.
Failure to meet an SLA results in penalties, demotion in ranking algorithms, an increase in dispute rates, and higher support costs. When dealing with thousands of orders, even a few percentage points of unmanaged delays can significantly impact your margin…
ROI Comparison: No-Show vs. Notification
An undelivered order typically results in a refund from the merchant, particularly in B2C transactions. However, when you factor in the resources used to prepare the order, the associated administrative procedures, and any logistics costs incurred by the e-merchant, the financial impact can quickly become significant.
Plot | No-show fee (1 package) | Cost of notification (3 text messages) |
No alerts | €15–25 (redelivery + 30 minutes of support + refund if unsatisfied) | – |
With a notification alert | €0.15–0.20 (RCS/transactional SMS) + time savings | Net savings: €14–€24 |
When a lack of information costs more than a delay
No-shows have two main consequences: immediate costs (redelivery and customer support) and damage to reputation. A customer who doesn’t receive their package loses trust in both the online retailer and the marketplace, is reluctant to place another order, and spreads dissatisfaction.
Aproactive message like “Delay detected—would you prefer a new delivery slot tomorrow between 10 a.m. and 12 p.m. or a pickup location?” reduces complaints by 80%, maintains customer trust, and protects your profit margins.
Design notification processes that protect your SLAs
From basic tracking to smart notifications
Most e-commerce businesses settle for a simple “Your package has been shipped” email, sometimes accompanied by a carrier tracking link.
To ensure your SLAs are met, you need to go a step further and establish notification processes based on real-time statuses from your TMS and WMS.
Each key status should automatically trigger the appropriate notification on the appropriate channel, with the appropriate level of urgency.
Example of a simple process (TMS/WMS connected):
- Package ready for pickup → Text message: “Shipped + tracking link”
- Delay detected (transportation issue, overloaded route) → SMS + email: “Delay + new time slot”
- Delivery postponed to the next day → Text message: “New date + link to options”
- Package delivered → Confirmation via text message or email.
Multi-channel: SMS, email, push notifications… and fallback
Not every customer responds to the same channel: some read everything via email, while others only use mobile devices.
🚀A multichannel platform like Docoon lets you orchestrate the winning combination: SMS + push notifications for real-time updates, email for details. You can also set up fallback mechanisms: if the push notification isn’t received, you automatically switch to SMS; if RCS isn’t available, you fall back to standard SMS.
ROI: Reducing the Hidden Costs of Delays
Even without precise figures, the business impact is clear:
✔️Fewer calls to customer service (every call avoided saves time).
✔️Fewer disputes and refunds related to “not received / not notified.”
✔️Highest seller rating on marketplaces, meaning greater visibility and more sales.
→ By implementing an API-driven SMS and email delivery delay notification system, you’ll quickly recoup the cost of the messages through reduced support costs and penalties.
A concrete before-and-after example
BEFORE(without Docoon): Delay detected at 2:00 p.m. (overloaded delivery route). Customer calls customer service at 4:00 p.m., ticket opened, Amazon dispute, redelivery on day 2 → €20 cost + 1-star review.
AFTER(with Docoon): TMS reports a delay → Docoon API sends an SMS at 2:05 PM: “Delay with your package #123. New delivery window tomorrow 10 AM–12 PM or pickup location? [RCS buttons]”. Customer replies “Pickup location”, complaint avoided, SLA met → €0.20 + customer satisfaction.
Connect Docoon to your TMS/WMS for real-time alerts
TMS, WMS: The Foundation of Real-Time Data
The WMS manages order picking, quality control, and the delivery of packages to the loading dock.
The TMS then coordinates transportation, routes, and carriers, and updates the status (picked up, en route, delivered, incident).
The key is real-time synchronization between the WMS and TMS, followed by the transmission of these statuses to your communication platform.
Docoon as a notification component connected via API
The Docoon communication platform integrates natively with your software, websites, and business applications via REST or SOAP APIs.
It can handle very large volumes of transactional messages, alerts, and critical data feeds across all channels (SMS, email, voice, fax, mail, certified messages, push notifications).
Specifically, your TMS or WMS sends an API call to Docoon as soon as a critical status is detected (delay, package issue, changed time slot), and Docoon automatically triggers the most appropriate notification.
Dashboards, Monitoring, and SLA Management
With Docoon, you have access to dashboards that let you track your campaigns in real time: deliverability, open rates, errors, responses, and unsubscribes. These metrics help you identify which strategies work best and which segments respond particularly well to SMS or RCS.
You can also integrate this data into your own tools (BI, CRM, customer portal) to manage your delivery SLAs and adjust your sales commitments.
Take it further with the RCS: Enhanced Notifications by Docoon
From simple text messages to rich media messages
RCS (Rich Communication Services) is the enhanced successor to SMS: text, HD images, video, buttons, carousels, geolocation, and quick replies. It works directly within the native messaging app, without requiring the installation of any additional apps, and offers a user experience similar to WhatsApp or Messenger, but within a more controlled environment.
Docoon has integrated RCS into its multichannel platform, adding this channel on top of the existing one, using the same API and tools.
RCS Use Cases for E-commerce Logistics
In e-commerce logistics, RCS opens up a range of practical applications:
- Delivery delay notification now includes “Reschedule,” “Change Address,” and “Deliver to a pickup location” buttons.
- Display an embedded map to see where the package or the nearest pickup location is.
- Sending carousels to select a new time slot or an alternative delivery method (home delivery, pickup point, curbside pickup).
Everything takes place within the same chat thread, without redirecting the user to an external site that isn't optimized for mobile.
Reliability, SMS fallback, and scalability with Docoon
Docoon comes from the world of critical transactional data flows: 2FA codes, sensitive notifications, and regulatory alerts. When applied to RCS, this means: technical monitoring of data flows, error handling, network quality, and, most importantly, automatic fallback to SMS if RCS is not available on the device.
🚀Yougain an additional rich channel without having to add more tools, connectors, or dashboards, and you maintain the same ROI and SLA metrics as for your transactional SMS campaigns.

FAQ – Delivery Delay Notifications and Docoon
1/Why set up SMS notifications for delivery delays instead of just an email?
Text messages are read almost instantly, with open and read rates far higher than those of email, which is critical for notifying a customer of a delay or a change in schedule. When used in conjunction with email, text messages reduce customer service calls and disputes arising from a lack of information.
2/How does Docoon integrate with my existing TMS or WMS?
Docoon offers REST and SOAP APIs to integrate with your business applications, TMS, WMS, ERP, or OMS. Your systems send logistics status updates to Docoon, which then orchestrates notifications through the appropriate channels based on the scenarios you have defined.
3/ Can SMS, email, push notifications, and RCS be combined in a single notification scenario?
Yes, the Docoon platform lets you schedule your messages across multiple channels from a single interface and using a single API. You can set up sequences (e.g., email followed by SMS if the email isn’t opened, RCS with SMS fallback, etc.) to ensure your messages are delivered successfully.
4/What is the significance of the RCS for e-commerce logistics?
RCS allows businesses to send rich messages featuring buttons, maps, carousels, or quick replies directly within the customer’s native messaging app. For logistics, this makes it easier to reschedule a delivery slot, choose a pickup location, or confirm an option—all without leaving the conversation.
5/How can I track the ROI and performance of my late-notification alerts?
Docoon provides detailed statistics on your mailings: deliverability, open rates, clicks, responses, and unsubscribes. You can use this data to refine your notification strategies, reduce support costs, and manage your delivery SLAs based on real-world performance.
(1) SLA: Service Level Agreement. A contract between a service provider and a client that defines the service to be provided and the expected performance level. An SLA also describes how performance will be measured and verified, and the consequences if performance levels are not met.
(2) TMS: Transportation Management System. Software designed to manage freight transportation and delivery operations (route planning, shipment tracking, etc.)
(3) WMS: Warehouse Management System. Software designed to automate the internal operations of a warehouse or distribution center. It handles inventory management and tracks product movements.
