Why does my abandoned cart test email work once and then never again?
Abandoned checkout emails have several silent skip conditions and a built-in delay, so here is how to test the automation properly instead of guessing from your inbox.
What's going on
You add an item to your own store, abandon the checkout on purpose, and then nothing happens. Or it works once, and the next test run sends nothing at all, with no error anywhere in the admin. Trying to verify that abandoned cart recovery emails actually work turns into a guessing game: was the test too fast, was the email address wrong, is there a delay nobody told you about, or is the automation actually broken for real customers.
This is a genuinely common source of confusion because Shopify's abandoned checkout system has several conditions that quietly prevent an email from sending, plus a built-in delay before anything goes out, and none of that is obvious from the storefront side. A merchant testing in good faith can easily hit one of these conditions by accident and conclude the feature is broken when it is actually working as designed.
Why it happens
Shopify only marks a checkout as abandoned after a period of customer inactivity, and the notification adds its own wait time on top of that before it actually sends. A test checked a few minutes later will often look like nothing happened, simply because nothing was supposed to happen yet.
On top of timing, Shopify deliberately skips sending in several situations: the checkout was completed before the email went out, an item went out of stock, the customer entered only a phone number and no email, the order was entirely free products with no shipping charge, the store cannot ship to the address given, or, on the newer Flow based automation, the audience settings exclude customers who have not opted into marketing.
Testing habits make it worse: a fake or disposable email address can be silently filtered or bounced before it reaches an inbox, and testing in a browser with a saved customer session can auto-complete the checkout instead of actually abandoning it, so the trigger never fires in the first place.
4 ways to fix it
Test with a real, working inbox instead of a throwaway address
Use an email address you actually control, such as a plus-addressed variant of your own address, rather than a made-up or disposable one. Mail providers and spam filters can silently drop messages sent to addresses that look fake or that bounce, which is one of the most common reasons a test never arrives at all. Place the test order from a private or incognito browser window so there is no saved customer session that might auto-complete the checkout before it can actually be abandoned, add a product to the cart, enter that email, and then close the tab or leave the checkout without paying.
Learn the conditions that make Shopify skip the email on purpose
Shopify will not send an abandoned checkout email in a number of situations: if the checkout is completed before the email would go out, if an item goes out of stock, if the customer only provided a phone number instead of an email, if the order is entirely free items with no shipping charge, or if the store cannot ship to the address given. If you are using the newer Shopify Flow based version of this automation, also check its audience or targeting settings, since it may be limited to customers who have opted into marketing rather than sending to every abandoned checkout. Any one of these can make a good-faith test look like a bug when the system is actually behaving as configured.
Expect a real delay, and don't judge a test in the first few minutes
A checkout is only considered abandoned after a period of customer inactivity, and the notification itself typically waits some additional time on top of that before sending, rather than firing immediately. If you check your inbox right after abandoning a test checkout and see nothing, that is often expected behavior rather than a failure. If you are testing on a Shopify Flow based abandoned checkout workflow, look at the wait step in the workflow itself to see the actual delay configured, and adjust it temporarily for testing if you need faster feedback, then set it back afterward.
Check the automation's own settings and history instead of guessing from your inbox
Rather than treating a missing email as unexplained, go to the settings for your abandoned checkout notification or workflow and review how it is configured, and check Orders under Abandoned checkouts to see whether Shopify recorded the checkout and whether a recovery email was associated with it. If the automation runs through Shopify Flow, its run history will show whether the workflow triggered, what each step did, and whether the send step ran or was skipped, which turns debugging into reading a concrete log instead of waiting on an inbox and guessing.
Bottom line
Most reports of "the test didn't work" turn out to be one of Shopify's documented skip conditions, a delay that simply hasn't elapsed yet, or a test email that was filtered before it ever reached an inbox, not a broken store. Test with a real inbox and a clean browser session, understand the skip conditions and delay before you conclude anything is wrong, and use the automation's own settings and run history to confirm what actually happened rather than judging it purely by what shows up in your inbox.
