Many brands stop selling after the first purchase.
But smart brands know that this is where the real money starts. Customers who bought are easier to sell to again, after all.
That’s why your post-purchase flow should be more than just a receipt and tracking link. It’s your big chance to turn a one-time customer into a loyal repeat buyer.
So… what emails do you actually write? That’s what this article is here to answer.
You’ll learn 8 post-purchase emails that drive repeat sales and help build a base of loyal, long-term customers — plus a few tips to optimize your flow for maximum revenue.
Why the Post-Purchase Flow is a Revenue Driver
Customers are most engaged after they buy. They’re excited. They’re looking at your emails if for nothing else than to see updates on your products.
That’s why post-purchase flow is so crucial.
But it’s not JUST because excited customers in “buyer mode” are ready to buy again.
This flow is a key player in cementing customer loyalty. Meaning repeat purchases. At scale, that leads to a higher LTV and, by extension, less reliance on ad spend!
It’s one of the 5-6 flows I look at when auditing accounts and often one of the first I tackle after the low-hanging fruit (like abandonment flows).
The post-purchase is where you:
- Reinforce their decision: Defuse buyer’s remorse and get them excited for their purchase
- Onboard them into the brand: As a customer rather than a new lead
- Guide to their first “quick win”: Get them results, and they’ll want to stick around.
- Show them more ways to use the product: Be helpful and help them get more wins.
- Upsell/cross-sell: Show other complementary products to secure that next sale.
A well-structured post-purchase experience can turn that one-off purchase into a long-term customer who buys repeatedly…
And even spreads the word about you.
8 Post-Purchase Emails That Drive More Repeat Sales
Let’s discuss 8 post-purchase emails that drive more repeat sales now and in the long term.
Note that I ordered these roughly, but NOT EXACTLY in the same order they may appear in flows. For instance, an order confirmation will always be first.
Meanwhile, however, your replenishment reminder may come later OR be a separate flow if the product lasts longer.
1. Excitement-Building Order Confirmation (With a Relevant Upsell)
Lots of customers open the order confirmation. Why waste that ultra-valuable real estate with something boring?
Use your order confirmation to build anticipation and reinforce the customer’s purchase. Show why the customer made a great decision. This overcomes that pang of buyer’s remorse EVERYONE feels post-purchase…
Meaning fewer refund requests and more engagement with the product (and your emails).
A few things you can do here:
- Testimonials: Makes the customer feel a part of something while adding more proof. For example, “You’re about to join 10,000 happy PRODUCT users, like John Doe, who said: [TESTIMONIAL]”.
- Relevant upsell/cross-sell: ONLY if it fits well. For example, I cross-sold an app that worked perfectly with my client’s product. It made a few affiliate sales (my client was an affiliate), effectively upping the AOV.
- Add humor and personality: Be funny. Use some personality. Tell a story about your excitement when [CUSTOMER]’s name popped up on your screen.
Alternatively, or additionally, you can add a recommended product block at the bottom without a hard sales push. More on that in #3, as I haven’t done this same thing in an order confirmation.
2. Product Education / How-To Use Email
The educational email helps the customer get the most out of the product.
The faster they get that first “win,” the quicker they become a loyal customer. That only multiplies if you help them get EVEN MORE out of the product — if they get more out of it, they get more value for the price paid.
I use a few of these throughout.
First is the “quick-start guide.”
It gives them concise details on opening, setting up, using, consuming, charging, or whatever else is involved in enjoying the product.
The goal is to be helpful and create a positive customer experience… while “greasing the wheels” toward that first quick win.
Beyond that, you can sprinkle education emails throughout that:
- Remind them of periodic events (for example, “don’t forget to charge your XYZ Headphones overnight”)
- Show them other ways to use the product
- Highlight how to care for the product (cleaning, washing, etc.)
Some of these lend themselves to upsells.
For instance, sell a second set of towels so the customer has them if their main set’s in the wash.
3. Shipping/Delivery Confirmations (With Recommended Product Blocks)
One of the easiest ways I’ve made clients some extra cash is by dropping a recommended product block in these emails.
Customers can just ignore it… or, since they’re anticipating delivery or excited after receiving it, click through and buy one of those product block recommendations.
It won’t be a TON of cash. I mean, I added about $500 in 1.5 months for a client doing $30k/month in email/SMS revenue.
But it’s dead simple. Add it to more “transactional” emails, and you could add a few hundred to a few thousand extra $$$ in easy sales.
You could work in a more formal upsell/cross-sell if you do so carefully. Don’t force it, but slide it in if it makes sense.
For instance, maybe you sell protein powder. An upsell could be a food tracker app for which you’re an affiliate, or your own products, such as a preworkout.
NOTE: You can turn a delivery confirmation email into a “Quick Start Guide” if you want. Up to you.
4. Replenishment Reminder (For Consumables or Wearables)
Sell consumable products, like household goods or office supplies? Don’t make customers remember to reorder (or worse, run to a competitor) — remind them to replenish!
Timing this email depends on your product’s usage cycle and shipping times. For instance, many supplements come in a 30-day supply. Time that replenishment email for somewhere between days 24 and 28 depending on shipping times.
Pro tip: Use your replenishment email to upsell MORE of the same product. For instance, if you sell flavored water, you could upsell to a larger amount. The customer gets bulk savings and doesn’t have to order as often… while you enjoy higher cash flows.
5. Dedicated Upsell/Cross-sell
Later in the flow is a good time to drop in a dedicated upsell/cross-sell.
Upselling means selling more of the same product. That could mean:
- The second order of a nonconsumable: For example, a backup version of the same water bottle.
- A larger version of a consumable product: For example, a bigger pack of beef tallow.
- An upgraded version of the same product: For example,
- A subscription/recurring delivery: For example, recurring delivery of scented candles.
Cross-selling means selling a complimentary product. That could mean:
- A complimentary, different-category nonconsumable: For example, selling bedsheets to someone who bought pillowcases.
- A complimentary, different-category consumable: For example, selling a protein powder to someone who bought preworkout.
- A different consumable from the same category: For example, selling a different candle scent.
Ideally, you have a short hook that isn’t directly selling. But that’s not always necessary.
6. Special Incentive
Has a customer made it late in the flow without a second purchase?
Throw them a special incentive, like a one-time discount or free gift. Frame it as a “thank-you” instead of a desperate bribe to buy again.
I don’t recommend every brand do this or keep it permanently. Repeat sales are meant to be where you make profits (after taking a loss on the initial purchase discount lead magnet)…
So a second-purchase discount may not be for everyone. The higher your average per-product profit margin, the more latitude you have for special discounts.
That said, you can test this and see if getting that second purchase at a discount boosts LTV dramatically.
For example, if you have two products that pair well together as a “hero pair,” then getting that second product into their hands at a discount could be worth it.
7. Review Request
Review request emails are underrated in what they offer you.
First, social proof sells. The more reviews you gain, the better you look to new leads… and the more marketing material you have for emails, ads, and more.
But there’s more.
When a customer writes a positive review, they’re actively thinking about why they like your brand and product. That reinforces their loyalty.
It follows that the perfect time to ask them to refer friends/family (and introduce your referral rewards) is right after they write the review.
Offering the customer a small “thank-you” incentive — like a discount — could boost review submission rates while selling more.
Yes, they’re discounted sales. But you get more reviews, which pays off in the long run.
Pro tip: Give customers “prompting” questions (like “What benefits have you noticed with [PRODUCT]?”) to spark ideas for the review. They don’t have to think as hard, boosting submission rates while letting YOU craft the review structure to make it as useful and persuasive as possible.
8. Loyalty/Rewards Invitation
Loyalty rewards programs are an easy way to turn one-off customers into repeat buyers.
So show off your loyalty program in a dedicated post-purchase flow email. It’s a great place to upsell since you can nudge them toward the next purchase to earn points.
Speaking of…
I like to be detailed here. I will do the following:
- Walk through how to earn: Each method gets a subsection with a few lines. Remember, this flow is somewhat of a “helper” flow, so they’re willing to read an email that shows, in detail, how to get more points.
- Example of how redemption works: How to redeem, how much a point is worth, minimum redemption thresholds, etc.
- Show how to access/see their point balance: Both written instructions and, if applicable, screenshots for extra clarity.
I also tell them to bookmark the email just in case. One more micro-commitment and also gives them an easy way to refer back to how to earn.
Yes, this is a perfect place to do another upsell. Encourage them to accumulate more points by making that next purchase.
Show them that they already HAVE points from their first purchase, too. That nudges the next sale because, by having points initially, they’re already closer to that “free/discounted” product.
How to Optimize Your Post-Purchase Flow for Maximum Sales
Having the right emails is a great start. But here are some other ideas to squeeze even more out of your post-purchase flow:
Timing
Don’t send everything in the first 48 hours. Or even the first week.
Many brands can drip them out over a few weeks to create an “experience” around the product. That’s what it’s about — building a relationship and continuing to “sell” them on your brand.
Personalization
Use customer data if possible, and not just their name. For example, recommend products based on what they bought. Or perhaps cross-sell to a complimentary category based on their purchase.
This makes the sale feel less like a pitch and more like you’re being helpful. That wins customer trust and raises the chance they buy again.
Calls-To-Action (CTAs)
Every email should have a clear CTA. Even those that don’t sell. Whenever a customer takes an action, you move toward some business objective.
CTAs include:
- Buying (revenue)
- Replying (deliverability, customer data, potential sales)
- Leaving a review (social proof, marketing material, customer research)
- Checking out their loyalty rewards (potential sales)
- Referring a friend (potential sales)
Getting them to take an action also increases their loyalty since each action is a micro commitment. When people do those small favors for you, they like you more. It starts to feel like a relationship.
Exclusion
Don’t send active post-purchase flow customers your regular broadcasts. You might cause emails to overlap.
Instead, create a flow exclusions segment with the post-purchase flow as one of the flows to exclude. Exclude this segment whenever you mail your list.
If someone buys while in your post-purchase, filter them out. No need to keep going if they bought again.
Test and Refine
No flow is ever 100% “finished.” Analyze which emails get the best data and study why. Try new copy, primarily, and consider if reordering certain mid-flow emails could enhance the experience.
You can also test timing and subject lines, but there’s a good chance these changes won’t cause a huge difference if your flow was decent the first time.
Master the Post-Purchase Flow
Post-purchase flows don’t just thank customers for their order… They help you drive more repeat sales without spending a dime extra on ads.
That’s why it’s one of the first places I look when auditing accounts.
Adding the right emails to create a cohesive customer experience is one of the most effective ways to boost LTV and make the most of your buyer list.
So look at your current post-purchase flow.
Are you sending all 8 of these? Or at least many of them?
If not, you’re likely leaving money on the table. Try adding one or two in — or reach out if you want a second set of eyes.
