The moment after an order is when a customer pays the most attention to you. They are waiting for a parcel, wondering whether they chose well and, if the experience goes right, open to buying again. Post-purchase emails cover that whole stretch: the confirmation and delivery updates, the thank-you, the review request, the second order and, over time, loyalty. This guide explains which of these are transactional and which are marketing, what to send in the first 30 days, how to ask for reviews, how to time reorder reminders, and how to reward your best customers.
Transactional and marketing emails after an order
Some post-purchase emails are part of the service the customer paid for. Others are marketing. The difference matters for consent, for unsubscribes and for how you send them.
Transactional messages go to every buyer because they relate directly to the order. Marketing messages go only to customers who agreed to hear from you, and include an unsubscribe link.
| Type | Notes | |
|---|---|---|
| Order confirmation | Transactional | Order number, items, total, payment method and delivery address |
| Tax invoice | Transactional | A GST invoice as a PDF attachment or a link |
| Shipped and out for delivery | Transactional | Courier name, tracking link and expected date |
| Refund or return processed | Transactional | Amount, method and how long it takes to reach the account |
| Thank-you and review request | Marketing | Send to customers who opted in to marketing |
| Cross-sell and reorder reminders | Marketing | Send to customers who opted in to marketing |
| Loyalty rewards and referral offers | Marketing | Send to customers who opted in to marketing |
Don’t slip promotions into transactional emails to reach people who haven’t opted in. A small, relevant note is common, but a delivery update that is mostly a sale banner is marketing in disguise.
The first 30 days at a glance
The timings below suit a typical online store delivering within a week. Adjust them to your delivery times and how quickly customers use the product.
| When | Its job | |
|---|---|---|
| Immediately | Order confirmation | Reassure: the order is in, here is what happens next |
| On dispatch | Shipping update | Tracking and expected delivery date |
| A day after ordering | Thank-you | Welcome the customer, set expectations, share care or usage tips |
| About a week after delivery | Review request | Ask how it went, with a quick rating |
| Around two weeks after the first order | Second-order nudge | A reason to come back, for those who haven’t |
| When the product is likely running low | Reorder reminder | For consumables: a reminder at the right moment |
The thank-you email
- Send it from a person or your brand name, and write it like a note, not a receipt.
- Repeat the most useful facts: expected delivery window and how to contact you if something goes wrong.
- Share something that improves the experience: how to wash a handloom saree, how to brew the tea, how to set up the device.
- Tell first-time customers a little about your brand, since they may know only the product they bought.
- Leave out discounts. The customer has just paid; an immediate offer can make them feel they paid too much.
Cash on delivery and returns
Cash on delivery is still common in Indian e-commerce, and it brings its own email needs. A clear confirmation helps reduce refusals at the door: remind COD customers of the amount payable and the expected delivery date, so the parcel isn’t a surprise.
For later orders, a short email explaining the benefits of paying online, such as faster processing, easier refunds or a small prepaid discount if you offer one, can gently shift customers towards prepaid. Keep the tone helpful rather than critical of COD.
Returns and exchanges are a test of trust. A prompt email when a return pickup is booked, and another when the refund is processed, saves a lot of anxious calls to your support team.
Ask for reviews at the right moment
Ask too early and the product hasn’t arrived or been used. Ask too late and the customer has moved on. For most products, about a week after delivery works; for skincare or supplements, give people time to notice a difference.
Make the first step tiny. A star rating or a 0 to 10 score inside the email, answered with one tap, gets far more responses than a link to a long form. You can then ask happy customers to write a public review and route unhappy ones to support.
Act on low scores quickly. A customer who rated you 3 out of 10 and received a personal reply the same day may still become a loyal one.
If you sell on marketplaces as well as your own website, point people to the place where a review helps you most. Never offer a reward only for positive reviews; it misleads other shoppers and can break platform rules.
Earn the second order
For many stores, the hardest order to win is the second one. A first-time buyer took a chance on you; a second order means they decided you are worth coming back to.
Two approaches work well together. A cross-sell, a week or so after delivery, suggests items that go with what they bought: a blouse piece with the saree, a refill pack with the starter kit, a case with the phone. And for first-time buyers who haven’t returned after a couple of weeks, a second-order nudge can include a modest incentive.
For example, a Jaipur store selling block-print bedsheets might suggest matching pillow covers a week after delivery, and offer first-time buyers who haven’t returned after three weeks free delivery on their next order.
Be selective with offers. Customers who reorder on their own don’t need a discount, so check whether someone has already ordered again before sending one.
Time reorder reminders to each customer
If you sell things people run out of, such as coffee, pet food, skincare, diapers or cleaning products, a reorder reminder is often the most useful email you can send. The simplest version is a fixed gap after each order, for example 30 days for a one-month supply.
A better version uses each customer’s own rhythm. One customer reorders every 25 days, another every 40. Reminding each a few days before their usual date, with the products they usually buy, feels like service rather than marketing.
Reward loyalty and ask for referrals
- Recognise your best customers when they pass a spending threshold, with early access to sales or a small gift rather than constant discounts.
- Ask repeat customers who still read your emails to refer a friend, with a reward for both people if it suits your margins.
- Send a birthday email with a treat, if customers chose to share their birthday.
- Ask for a quick recommendation score a couple of weeks after someone becomes a customer, and follow up personally on low scores.
- Thank customers on their first-order anniversary, especially for subscription or membership products.
Set it up in MailNesto
- Connect your store Connect Shopify, WooCommerce, Razorpay or your own checkout through the Orders API, so orders and revenue are recorded against each contact.
- Send service emails through the API Order confirmations, GST invoices, shipping updates and refund notices can go through the transactional email API, with templates, PDF attachments and a searchable message log. Transactional email has its own sending stream, separate from marketing.
- Start the post-purchase journeys Recipes include “Thank-you & review request” (a thank-you, then a review request seven days later), “Second-purchase nudge” (an offer 14 days after a first order, only if they haven’t ordered again), and “Goes well with…” (suggestions a week after an order).
- Add reorder reminders “Restock reminder” emails customers 30 to 45 days after an order. “Time to reorder” uses each customer’s predicted next order date and sends a reminder three days before, with products picked for them.
- Recognise loyal customers “VIP welcome” tags customers whose total spend passes a level you set, “Ask happy customers to refer” emails repeat buyers, and the recommendation-score recipe asks a 0 to 10 question two weeks after someone is tagged as a customer. Survey and NPS blocks collect answers inside the email.
Measure what matters
- Repeat purchase rate: the share of first-time customers who order again within 90 days.
- Time to second order, and whether it shortens as you improve the journey.
- Revenue per automation, to see which post-purchase emails actually earn their place.
- Review and rating response rate, and the share of low scores you followed up on.
- Unsubscribes after each post-purchase email. A spike usually means the timing or frequency is off.
- Predicted spend over the next 12 months for customers who went through the journey, compared with those who didn’t.
Questions
Do order confirmations need marketing consent?
Order confirmations, invoices and delivery updates are transactional: they relate directly to the purchase and are expected by the customer. Review requests, cross-sells and offers are marketing, so send them only to customers who opted in.
When should I ask for a review?
About a week after delivery suits most products. For items that take longer to show results, such as skincare or supplements, wait two to four weeks. Base the timing on delivery rather than order date if your delivery times vary a lot.
Should I offer a discount for the second order?
Only to customers who haven’t come back on their own after a reasonable time. Check for a second order before sending, so people who were going to buy anyway don’t receive a discount they didn’t need.
How many post-purchase emails are too many?
Count only the marketing emails. Three or four in the first month after an order is a reasonable ceiling for most stores, alongside the transactional updates. Watch unsubscribes and trim the series if they rise.
Can I include product recommendations in a shipping update?
A small, relevant row may be acceptable, but the email’s purpose must stay the shipping update. If the recommendations become the main content, treat it as marketing and send it only to people who opted in.
