Email has open rates around 20 percent. WhatsApp sits above 90 percent. If you are trying to increase average order value on your Shopify store and you are not using WhatsApp to do it, you are sending your upsell messages through the channel that nine out of ten customers ignore.

WhatsApp upsell messages work because they land where customers already are, in a space they associate with personal conversations rather than promotional noise. When those messages are timed well, written naturally, and relevant to what the customer already bought, they feel like a helpful recommendation rather than a push notification. That distinction is what separates a WhatsApp upsell that converts from one that gets muted.

This post covers the specific WhatsApp upsell message types that increase Shopify AOV, when to send each one, and what the messages actually look like in practice.

Why WhatsApp Is the Right Channel for Shopify Upsells

Before getting into the message types, it helps to understand why WhatsApp specifically outperforms other upsell channels for Shopify stores.

The first reason is visibility. Most customers check WhatsApp within minutes of receiving a message. The same customer might not open a promotional email for two days, if at all. When your upsell message is time-sensitive, whether tied to a limited bundle, a restock, or a post-purchase window, WhatsApp delivers it when intent is still warm.

The second reason is conversational format. WhatsApp messages are short, direct, and personal. They do not look like marketing. A well-written WhatsApp upsell reads the way a recommendation from a knowledgeable friend would read, which makes customers far more receptive to it than a designed promotional email with a hero banner.

The third reason is the buying window. The period immediately after a customer places an order is one of the highest-intent moments in the customer relationship. They are satisfied, engaged, and thinking about the brand. WhatsApp order confirmation messages already land in this window. Upsell messages sent at the same moment benefit from the same receptivity.

6 WhatsApp Upsell Messages That Increase Shopify AOV

1. The Post-Purchase Complement Upsell

The most natural WhatsApp upsell is the one sent right after a purchase, recommending something that pairs with what the customer just bought. This is not a generic "you might also like" message. It is a specific, contextual recommendation tied to the exact product they ordered.

Timing matters here. Send this within 30 to 60 minutes of the order confirmation. The customer is still in the buying mindset. Their card is already out. A relevant add-on at this moment feels like a helpful tip, not a sales pitch.

The message should be brief. It should name the product they just bought, recommend one specific complement, and give them a direct path to add it. A discount helps but is not always necessary. The relevance of the recommendation does more work than the discount size.

Example message:

Hey [Name], thanks for your order! Since you picked up the [Product], a lot of our customers also grab the [Complement Product] to go with it. It is [one-line benefit]. Want to add it to your order before it ships? [Link]

Upsell automation Shopify makes this scalable — you set the logic once, connect it to your product catalog, and the right complement gets recommended automatically based on what was purchased, without you manually sending messages.

2. The Bundle Offer After a Single Item Purchase

Customers who buy one item from a bundle are strong candidates for the full set. They have demonstrated interest in the category. A WhatsApp message that introduces the bundle at a slight discount, framed around value rather than pressure, converts well because it extends a decision the customer already made.

This message works best when the bundle discount is genuine and the framing is about what the customer gets, not what they save. Savings-focused language feels transactional. Benefit-focused language feels like you are doing them a favour.

Example message:

Hi [Name], we saw you just ordered the [Single Item]. We have a [Bundle Name] that includes [Item 1], [Item 2], and [Item 3] together at [price]. Most customers who start with [Single Item] end up wanting the full set. Happy to set it up for you if you want — just reply and we will sort it. [Link]

This approach ties naturally into your broader cross-sell upsell strategies and is one of the fastest ways to increase average order value without running a site-wide promotion.

3. The Reorder Nudge at the Right Moment

For consumable products, topical products, or anything with a predictable usage cycle, a WhatsApp reorder message timed to when the customer is likely running low is one of the highest-converting message types available. It does not feel like an upsell at all. It feels like a reminder from a store that pays attention.

The key is timing. If your product typically lasts 30 days, send the message on day 25. If it lasts 60 days, send it on day 50. Pair the reorder message with a small loyalty discount or a slightly larger size option, and you have both a reorder and a natural increase average order value opportunity in the same message.

Example message:

Hi [Name], it has been about [X weeks] since your [Product] order. If you are getting low, now is a good time to restock — we have the [Larger Size / Bundle] available at [price] which works out better value per use. Here is the link if you want to grab it: [Link]

Post-purchase ecommerce strategy built around reorder timing is one of the clearest ways to convert one-time customers into repeat buyers, and WhatsApp is the channel where those messages actually get read.

4. The Exclusive Upgrade Offer for Recent Buyers

Customers who bought from you in the last 30 to 60 days are warm. They know your brand, they received their order, and if the experience was positive, they are more likely to buy again than a cold visitor. Sending a WhatsApp message with an exclusive upgrade offer, available only to recent buyers, plays on both the exclusivity and the existing relationship.

This message works well for stores that sell products with a clear upgrade path. The standard version versus the premium version. The starter kit versus the full kit. The single unit versus the multi-pack.

Example message:

Hey [Name], since you bought [Product] last month, we wanted to give you first access to [Premium Version] before we open it up publicly. It is [key difference] compared to what you have. As a recent customer you get it at [price]. Only a few available at this price — [Link]

Pair this with WhatsApp sales automation and you can run this type of campaign to segmented recent-buyer lists without manual effort. It is the kind of message that automate Shopify sales conversations handle well when the platform is connected to your customer purchase history.

5. The Low Stock Alert on a Wishlist or Related Item

If a customer browsed or previously purchased a product that is now low on stock, a WhatsApp alert is one of the most effective urgency messages you can send. It is not manufactured scarcity. It is genuine information delivered through the channel where they will actually see it.

This message works because it is useful rather than pushy. The customer is not being sold to. They are being informed. The urgency comes from the situation, not from the language.

Example message:

Hi [Name], we noticed you previously bought [Related Product]. The [New Product / Restocked Item] that pairs with it is almost sold out — only [X] left. Thought you might want to grab one before it goes: [Link]

Combined with product launch WhatsApp campaigns for new arrivals in the same category, this type of message builds a natural ongoing relationship where customers see WhatsApp notifications from your store as worth reading rather than worth muting.

6. The Thank You Message With a Soft Upsell

Not every WhatsApp upsell needs to lead with the product. A message that thanks the customer genuinely, checks in on their experience, and then mentions something relevant as an aside feels completely different from a promotional message. It converts well precisely because it does not feel like it is trying to.

This works best sent 5 to 7 days after delivery, once the customer has had time to use the product and form an opinion.

Example message:

Hi [Name], just checking in — how are you getting on with your [Product]? Hope it is everything you were expecting. If you have any questions at all, just reply here. Also, we just restocked the [Complement] in case you have been thinking about it. No pressure — just wanted to let you know. [Link]

This message style ties directly into repeat sales post-purchase strategy. Customers who feel looked after after a purchase buy again. Customers who feel sold to after a purchase do not.

What Makes WhatsApp Upsells Work

The message examples above share a set of characteristics that separate high-converting WhatsApp upsells from the ones customers ignore.

They are short. WhatsApp is not email. Three to five sentences is the ceiling. Anything longer starts to feel like a newsletter.

They are specific. A generic "check out our other products" message has no reason to exist. A message that references what the customer actually bought and recommends something directly related to it has a clear reason to land in their inbox.

They are well-timed. The post-purchase window, the reorder window, and the 30-day re-engagement window each have their own logic. Sending the right message in the wrong window is nearly as ineffective as sending the wrong message.

They are opt-in. Customers need to have agreed to receive WhatsApp messages from your store. Collect WhatsApp opt-ins at checkout and post-purchase to build a list that is both compliant and genuinely interested. A smaller, opted-in list outperforms a large, unfiltered one on every metric.

To build all of this without manually managing individual messages, WhatsApp chatbot sales automation handles the triggers, timing, and message delivery automatically.
