These three post purchase email templates take one afternoon to set up, cost nothing, and keep selling every night while you pack boxes.
If you run an eco product brand on your own, marketing is the thing you do at 11 pm, half asleep, feeling guilty about everything you did not post. So this guide is not about doing more. It is about building three emails once, on a free plan, in a single afternoon, and letting them work every night while you pack boxes.
These are post-purchase emails. They go to people who already bought from you, which is why they outperform everything else you could write: the hardest part, earning the first order, is already done. A repeat customer costs you nothing to acquire, and the brand that follows up is the brand that gets the second order.
Email 1: The thank-you that tells the real story (day 0)
Most order confirmations read like receipts. Yours should read like a note from the founder, because it is one. It lands minutes after the purchase, when the customer likes you the most, and its job is to turn a transaction into a relationship.
Send: immediately after the order, alongside the standard receipt your store already sends.
Subject: Your [product] is on its way (and the story behind it)
Hi [first name],
I am [founder name], and I just saw your order come in. Thank you. Orders like yours are literally what keeps this going.
While I get your [product] packed, here is the short version of why it exists: [two honest sentences. The gap you saw, the thing you refused to accept, the material you chose and why. Write it once, from memory, without marketing words.]
One practical thing before it arrives: [one genuinely useful tip about using, storing or getting the most from the product].
If anything is off with your order, reply to this email. It comes straight to me.
[founder name], founder of [brand]
The rules: plain text, no banner, no discount, no upsell. One honest story and one useful tip. The reply-to must be a real inbox you read, because answers to this email are gold.
Email 2: The review ask (day 14)
Reviews are the engine of a small product brand, and almost nobody asks for them properly. The trick is timing and wording: two weeks in, the product has been used, and the memory of buying from a real person is still warm.
Send: 14 days after the order, or 7 days after delivery if your store tracks it.
Subject: Has the [product] settled in?
Hi [first name],
Two weeks ago your [product] arrived. By now it has either earned its spot in your routine or it has not, and honestly, I want to know either way.
Would you take one minute and write what you actually think? Not the polished version. The real one. If something disappointed you, say it, that is how the product gets better.
[review link as a plain button or link]
It takes a minute and it helps more than you would guess: small brands live and die by what real customers say.
[founder name]
The rules: never trade a discount for a review, it breaks the platforms’ terms and readers can smell bought stars anyway. Ask for honesty, not for five stars. One ask per email, nothing else in it.
Email 3: The replenishment reminder (when it is running out)
This is the quiet money-maker. If your product gets used up, soap, coffee, balm, detergent, refills, someone who loved it will still forget to reorder, buy whatever is on the supermarket shelf, and drift away. Your job is to arrive one week before the jar is empty.
Send: [days your product lasts] minus 7 days after the order. A 60-day supply means day 53. If you sell sizes, set one timer per size.
Subject: About to run out?
Hi [first name],
Quick math on my side says your [product] is getting close to the bottom of the jar.
If it earned its place, here is the shortcut so there is no gap: [reorder link].
And if it did not, I would genuinely rather know why. Just hit reply.
[founder name]
If your product is not consumable, swap this for a care email: how to make the product last longer, sent at day 30. It sounds like the opposite of selling, and that is exactly why it sells: the brand that teaches you to buy less is the brand you trust when you buy again.
How to automate these post purchase email templates, free
You do not need new software or a paid plan for any of this. Every major store platform ships automation on its free tier. Block ninety minutes, write your three templates first in a plain document, then follow your platform below.
If you are on Shopify
- In your Shopify admin, open Marketing and then Automations. This is Shopify’s built-in tool; the free email quota is generous enough for a small brand, so do not install anything extra.
- Click Create automation and pick the post-purchase thank you template. Open its email step, delete the stock copy, paste Email 1, and change the sender name to your own name, not the brand’s.
- Create a second automation from the same trigger, order placed. In the flow editor, add a Wait step and set it to 14 days, then add the email step and paste Email 2. Put your review link where the template says so.
- Create the third one the same way: order placed, a Wait of your replenishment window minus one week (a 60-day product means 53 days), then Email 3 with the reorder link. If you sell more than one size, duplicate this automation per size and use the product filter in the trigger.
- Add the exit rule so nobody gets reminded about something they already rebought: in each automation’s conditions, stop it if the customer has placed a new order since. Shopify’s flow editor calls this a condition step; check customer’s number of orders against the date.
- Turn each one on, then place a one-dollar test order (or use a 100% discount code) with your own email, and watch the three arrive. Delete the test order after.
If you are on WooCommerce
- Install the free MailPoet plugin from Plugins, Add New. Its free plan covers small lists and includes WooCommerce automations. Connect it to your store when the setup wizard asks.
- Go to MailPoet, Automations, New automation and choose the WooCommerce trigger customer makes a purchase.
- First automation: no delay, one email step, paste Email 1. Set the from name to you and the reply-to to the inbox you actually read.
- Second automation: same trigger, add a delay step of 14 days, paste Email 2 with your review link. If you use a reviews plugin, its “write a review” URL for the purchased product goes here.
- Third automation: same trigger, delay of your product’s lifespan minus 7 days, paste Email 3 with the reorder link (the product page URL is enough).
- In each automation’s settings, enable the option to end it when the customer purchases again, so a reorder stops the reminders.
- Run a test purchase with your own email through the real checkout, confirm the three emails fire, then refund yourself.
Using the post purchase email templates on any other setup
- Open a free account on an email tool with ecommerce triggers, Brevo and Mailchimp both work on their free tiers, and connect your store from their integrations page.
- Build one flow with the trigger purchase completed and three timed sends: immediately, day 14, and your replenishment day. Paste the three templates.
- Set the flow to exit on a new purchase, send yourself a test order, and switch it on.
For the review email specifically, tools like Judge.me have free plans that automate the ask and collect the stars straight onto your product page, which is where they sell. If you go that route, skip Email 2 in your flow so the customer is not asked twice.
None of this is a trick. It is the same principle behind every sustainable online store we build: earning the second order costs far less than chasing a new first one.
The rules that keep these emails welcome
Plain text beats designed, every time, because it reads like a person. Send from the founder’s name, not the brand’s. Make every reply land in an inbox a human reads. One ask per email, never two. And stop the sequence the moment someone reorders, nothing kills trust like a reminder for something already bought.
Half an afternoon of setup, zero dollars, and from tonight on your best salesperson works while you sleep. That is the whole trick: not more marketing, just marketing that does not need you in the room.
If you would rather have the whole system built for you, flows, timing and copy, these post purchase email templates are only the first layer of what we build in marketing automation for sustainable brands.
