A customer orders hiking boots on Sunday. By Wednesday, they still don’t know whether their order has shipped. They check the retailer’s website, find no information and contact the customer service team.

The parcel might be moving exactly as planned. The problem is that the customer has no way of knowing, so a routine delivery turns into an unnecessary support inquiry.

Customers also want to hear more from retailers while waiting for their orders. In [Forrester’s 2025 consumer research](https://www.forrester.com/report/uk-shoppers-want-more-delivery-notifications-from-brands/RES181393), 82% of UK online adults found brand notifications helpful, while 65% wanted more information before their orders arrived.

Clear **post-purchase communication** gives customers that information before they have to ask. By keeping shoppers informed throughout delivery, you can reduce avoidable inquiries and build confidence in their purchases.

In this guide, we’ll cover what to communicate after checkout, which channels to use and eight practical ways to improve your approach, including how parcelLab can help.

## What is post-purchase communication?

**Post-purchase communication is the information you share with customers and the conversations you have with them after checkout.** It includes order confirmations, delivery updates, return instructions and interactions with customer support.

These interactions are part of the wider [post-purchase experience](https://parcellab.com/blog/what-is-post-purchase-experience/) and continue throughout the [customer journey](https://parcellab.com/blog/whats-the-post-purchase-customer-journey-everything-you-need-to-know/), even after delivery.

But not every message serves the same purpose. Some help customers stay informed about their current purchase, while others encourage them to shop with you again:

- **Transactional communication** keeps customers updated on their orders, helps them resolve delivery problems or informs them about refund progress.
- **Promotional communication** encourages future purchases through product recommendations, special offers or loyalty invitations. This falls under [post-purchase marketing](https://parcellab.com/blog/what-is-post-purchase-marketing/) and may require separate marketing permission.

Both have a place in your post-purchase communication strategy, but timing matters. Someone opening a shipping confirmation wants to know when their order will arrive. Give them that information first, and keep any promotional content secondary.

## Why does post-purchase customer communication matter?

Once customers place an order, they want to know when it will arrive and whether everything is going according to plan. If that information isn’t readily available, they may repeatedly check [tracking pages](https://parcellab.com/blog/guide-to-order-status-pages/) or contact your support team.

Proactive post-purchase communication reduces uncertainty, improves the customer experience and cuts unnecessary work for your team.

Here’s how it can benefit your business:

- **Reduce avoidable support inquiries.** Timely delivery updates answer common [WISMO](https://parcellab.com/glossary/wismo/) (“where is my order?”) questions before customers contact support.
- **Improve customer satisfaction.** Accurate [delivery estimates](https://parcellab.com/glossary/delivery-date-estimate/) and timely delay updates reduce uncertainty about when orders will arrive.
- **Encourage repeat purchases.** Reliable communication supports a positive [post-purchase](https://parcellab.com/blog/what-is-post-purchase-evaluation/) experience and gives customers more confidence to shop with you again.
- **Create more opportunities for repeat sales.** [Branded tracking pages](https://parcellab.com/blog/guide-to-branded-tracking-pages/) bring customers back to your website instead of carrier websites. You can use these visits to showcase relevant products or permitted offers, creating additional opportunities to engage customers and build brand loyalty.

Of course, more notifications don’t automatically mean better service. Too many can frustrate customers just as much as too little information.

## What should you communicate after checkout?

The right message depends on the customer’s immediate questions. Someone waiting for dispatch needs a different update from someone arranging a return.

Use the following stages to plan your communication throughout the purchasing process and beyond.

    Stage What to communicate When to send it     Order placed Confirmation, order summary and delivery estimate Immediately after checkout   Preparing Preparation progress, expected dispatch date and changes When preparation begins or dispatch expectations change   Shipped Dispatch confirmation, carrier details and tracking link After dispatch   In transit Shipping progress, delivery delays or revised delivery date When the carrier confirms pickup, reports a delay or updates the delivery estimate   Delivery day Arrival window or collection instructions When reliable details become available   Delivered Confirmation, delivery location and how to report missing or damaged items When the carrier confirms delivery   Return or exchange Return instructions, receipt confirmation and refund or exchange progress When the return is registered, received or processed   After delivery Product guidance, feedback request or permitted special offer Following delivery, based on the product and purpose of the message   

Sending a message at the right time is only part of the job. Its content should reflect what’s happening with that particular order.

For example, if an order ships in multiple parcels, a generic “Your order is on its way” notification can be misleading. Customers need to know which items have shipped and when to expect the rest.

**Example post-purchase messages:**

- **Order preparation:** “We’re preparing your order. We’ll send your tracking link as soon as it leaves our warehouse.”
- **Delivery delay:** “Your delivery is taking longer than expected. The updated arrival date is Friday. Check the latest status here.”
- **Split shipment:** “Two items from your order will arrive tomorrow. Your third item is shipping separately. We’ll let you know when it’s on the way.”
- **Return:** “We’ve received your returned item and are processing your refund. You can follow its progress here.”

Each example explains the customer’s current situation and what happens next, reducing the need to contact support for clarification.

## Which post-purchase communication channels should you use?

Once you’ve decided what to communicate and when, choose how to deliver those updates.

Start by separating routine messages from time-sensitive ones. Email is usually sufficient for order confirmations, while SMS or push notifications may be more useful when a delivery requires immediate attention.

Choose a primary channel for each message type. Use another channel when the update is urgent, requires action or follows the customer’s stated preferences.

    Channel Best use What to consider     Email Receipts, shipping details and return instructions Put the delivery status, expected date and tracking link first.   SMS Delivery-day alerts and urgent changes Keep messages short, identify your brand and link to more details. Check messaging permissions.   WhatsApp Delivery updates and two-way customer support Customers must opt in to receive business-initiated updates, which generally require approved templates.   Push notifications Timely alerts through your mobile app Customers need the app installed and notifications enabled.   Branded order status page Self-service tracking throughout delivery Show current tracking information and the status of each parcel in split shipments.   Live chat support Missing parcels, delivery problems and complex requests Give agents access to order details and previous conversations.   Returns portal and return notifications Self-service returns, exchanges and refund tracking Let customers choose eligible return options and send updates when their return is registered, received and processed.   

Direct communication like SMS can be especially useful when customers need quick updates on their mobile devices. Include a recognizable sender and a direct link to the relevant order information.

Whichever channels you choose, keep the information consistent. For example, if you notify someone about a delivery delay by SMS, the linked tracking page should show the same updated estimate.

Keeping this information consistent gets harder when you work with multiple carriers or ship orders in separate parcels.

That’s where [parcelLab](https://parcellab.com/) can help. As a [post-purchase experience platform](https://parcellab.com/blog/top-5-post-purchase-experience-software-providers), parcelLab combines order and carrier tracking data so you can automate personalized customer communication across email, SMS, WhatsApp and push notifications.

You can also provide a [branded tracking page](https://parcellab.com/blog/how-to-build-branded-tracking-pages-that-convert/) where customers see the latest status of their entire order. This gives them a convenient place to find updates without switching between carrier websites.

But notifications can’t resolve every customer inquiry. Sometimes shoppers need to ask questions or report problems. That’s where two-way communication through live chat and messaging apps becomes useful.

## Where does conversational commerce fit after purchase?

**Conversational commerce involves helping customers shop or get support through real-time conversations**, including messaging apps, live chat and AI-powered assistants.

Popular messaging apps such as WhatsApp and Facebook Messenger let customers ask questions through channels they already use. These chat apps can also support social commerce, helping potential customers discover products before checkout.

After purchase, the priority shifts to resolving issues with existing orders.

For example, if someone wants to change their delivery address, the response should depend on whether their order has shipped and whether changes are still possible.

This requires access to current order information and a way to connect customers with support when their request can’t be resolved automatically.

### How can chatbots and support agents work together?

A chatbot or virtual assistant can answer frequently asked questions about return policies, delivery windows or business hours. But answering questions about specific orders requires access to live tracking information and relevant customer data.

For example, when someone asks why their delivery is late, an AI assistant with access to the order status can provide an updated estimate rather than a generic explanation about shipping delays.

More sophisticated AI chatbots can also help agents manage multiple conversations by summarizing past interactions and supplying relevant order details.

Some situations still require human support. Damaged items or disputed refunds may need investigation, so your customer service software should route customers to an agent with the conversation history attached.

With [parcelLab’s AI-powered customer support](https://parcellab.com/wismo-agent/), retailers can automate responses to routine order and return inquiries using current tracking information. Requests outside the supported scope can be escalated to the customer service team.

For retailers handling high inquiry volumes, this reduces repetitive work while preserving live support for more complex cases.

### Embracing conversational commerce: how it helps generate sales

Customer service comes first after checkout, but these conversations can also create opportunities for future purchases.

For example, a customer asking how to care for a recently delivered product might appreciate a recommendation for a suitable cleaning kit. Using purchase history and relevant customer preferences, retailers can offer personalized recommendations rather than generic promotions.

Efficient customer interactions create cross-selling opportunities, as long as you have the appropriate marketing permissions.

The important distinction is whether the recommendation helps the customer with their original question. Address that need first, then consider whether a relevant offer would add value.

## 8 best practices for effective post-purchase communication

Whether you’re sending automated updates or responding to customers in chat, the goal is to provide accurate information in a way that’s relevant to their purchase.

Here are eight practical ways to improve your communication throughout the post-purchase customer journey.

### 1. Automate updates at important delivery stages

Set up automatic notifications when an order ships, a delivery is delayed, a delivery attempt fails, or a parcel arrives. Skip routine carrier scans unless they affect the customer’s expected delivery date.

With parcelLab, you can [trigger personalized notifications](https://parcellab.com/track-and-communicate/) based on order status and tracking updates from different carriers, keeping communication consistent across markets.

### 2. Tell customers what happens next

Include an estimated dispatch date in order-preparation updates, and notify customers if it changes. For click-and-collect orders, provide the pickup location, business hours and confirmation that the order is ready.

If an item is awaiting stock or can’t be tracked, explain when customers can expect another update. This also applies to orders collected in-store.

![parcelLab post-purchase communication features help provide personalized services improving customer loyalty](https://parcellab.com/wp-content/uploads/2022/06/parcelLab-screenshot-1024x509.webp)### 3. Notify customers about delivery delays early

Notify customers as soon as you identify a likely delay. Include a revised delivery estimate when available, or explain when they’ll receive another update.

parcelLab uses predictive analysis to identify shipments at risk of arriving late, allowing you to communicate proactively.

For example, outdoor retailer [Bergzeit](https://parcellab.com/case-studies/bergzeit-21-wismo-reduction/) introduced proactive delivery communication through parcelLab and reported **21% fewer WISMO inquiries**. See what parcelLab can do for you—[**book a demo**](https://parcellab.com/book-a-demo-platform-tour/).

### 4. Set clear rules for each communication channel

Assign routine shipping updates to email and reserve SMS or push notifications for urgent changes, such as [failed delivery](https://parcellab.com/blog/how-to-manage-failed-deliveries/) attempts. Avoid sending duplicate notifications across multiple channels.

For international retailers, adapt your channel choices to customer preferences and messaging permissions in each market. Review delivery and response rates to see whether your chosen channels are working.

### 5. Personalize messages and post-purchase experiences

Use customer and order data to tailor delivery updates, including the customer’s preferred language, delivery method and the status of individual shipments.

But personalization should go beyond messaging. With parcelLab, you can also [tailor the returns experience](https://parcellab.com/personalize-returns-journey/) based on customer segments and return policies. For example, eligible VIP customers might receive instant refunds, while first-time buyers could be offered exchanges before refunds, where permitted by law.

[Berlin Brands Group](https://parcellab.com/case-studies/bbg-88-open-rate/) used parcelLab to send updates in **12 languages** and reported **24% fewer customer service inquiries**.

### 6. Help customers find answers without contacting support

Identify your most common customer inquiries and provide self-service options. Customers should be able to check revised delivery estimates or initiate returns without speaking to an agent.

With parcelLab, customers can track their entire order through a branded page, including separate shipments. A [self-service returns portal](https://parcellab.com/self-service-returns-portal/) also lets them register returns and follow their progress.

Integrations with customer service software such as Zendesk and Gorgias give support agents access to relevant order information, helping them resolve issues without searching multiple systems.

### 7. Keep delivery updates separate from promotions

Put delivery information first in transactional messages. For [post-purchase upselling](https://parcellab.com/blog/what-is-post-purchase-upselling/), consider separate, appropriately authorized messages after delivery.

For example, you could recommend accessories based on purchase history or invite customers to join your loyalty program.

These [post-purchase engagement](https://parcellab.com/blog/how-to-increase-post-purchase-engagement/) campaigns create opportunities to cross-sell and encourage repeat purchases. A relevant discount code may increase engagement, but send promotional content only when applicable marketing rules permit it.

### 8. Keep order information consistent across systems

When customers receive updates from your store, carriers and the support team, the information should match. For example, if an order contains three parcels and only two have arrived, customers shouldn’t receive a notification saying their entire order has been delivered.

When integrating systems, make sure each shipment connects to the correct order and that your customer service team can access the same tracking information.

With parcelLab, you can [bring tracking data from multiple carriers together](https://parcellab.com/track-and-communicate/), provide order-level visibility for split shipments and keep customer notifications consistent throughout delivery.

## Is post-purchase communication allowed under GDPR?

Retailers can generally send customers information needed to fulfill their orders without obtaining separate consent for that processing.

Under [Article 6(1)(b) GDPR](https://commission.europa.eu/law/law-topic/data-protection/information-business-and-organisations/legal-grounds-processing-data_en), you can process personal data when it’s necessary to perform a contract with the customer.

This can include order confirmations, [shipping notifications](https://parcellab.com/blog/guide-to-shipping-notifications/), tracking links, pickup instructions and return or refund updates.

However, the rules change when you introduce promotional content. Sending assembly instructions for a recently purchased bicycle may be a useful service message. Adding a discount code for a helmet counts as marketing, even though the product is relevant to the original purchase.

Under [UK ICO guidance](https://ico.org.uk/for-organisations/direct-marketing-and-privacy-and-electronic-communications/guidance-on-direct-marketing-using-electronic-mail/), marketing emails and texts to individual customers generally require consent unless an exception applies.

The *soft opt-in* may allow you to promote similar products to existing customers if you collected their details directly during a sale or negotiation, allowed them to opt out at collection, and include an opt-out in every subsequent message. EU countries have their own electronic marketing rules.

To protect customer data, collect only what’s necessary for each purpose, explain how you use it, and restrict access to sensitive order details. Keep service communication separate from marketing permissions, especially when using purchase history to personalize interactions.

*Note: This is general information, not legal advice.*

## How to measure whether your post-purchase communication works

Once you’ve set up your communications, you need to know whether they help customers find answers and reduce avoidable inquiries.

Email open rates alone won’t tell you much. Track metrics that show how customers respond to your messages and whether they still need support.

    Metric What it tells you     WISMO inquiries per 1,000 orders Whether delivery-related inquiries are decreasing relative to order volume   Repeat contacts How often customers contact support multiple times about the same order   First-contact resolution Whether agents resolve issues without additional exchanges   Response times How long customers wait for support   Email clicks and tracking-page visits Whether shoppers follow links to check delivery information   Opt-outs and complaints Whether customers find notifications too frequent or unwanted   

Use these metrics to evaluate individual improvements. For example, if you start notifying shoppers earlier about potential delays, compare delivery-related inquiries before and after the change, accounting for differences in order volume.

With parcelLab, you can track communication performance and A/B test different email messages to see which versions encourage customers to check their order information.

You can also use [parcelLab’s AI assistant, Copilot](https://parcellab.com/copilot/), to investigate post-purchase data through natural-language questions. For example, ask which delivery notifications have the lowest click rates or which markets have the most delivery exceptions.

Copilot can help identify problems, recommend improvements and draft new notifications or update existing ones, with changes subject to your approval.

## Key takeaways: Give customers the answers they need before they ask

When customers repeatedly contact support about their orders, the problem often isn’t a lack of information. It’s that the information already available in your systems isn’t reaching them when they need it.

Improving post-purchase communication means connecting that information to the right customer interactions, from delivery notifications and tracking pages to conversations with support.

**parcelLab brings it all together.** By connecting order and carrier data, you can automate personalized updates, identify potential delays early and give customers a branded place to check their entire order.

Your support team also gets access to the information needed to resolve more complex inquiries, while communication analytics help you identify where improvements are still needed.
