Ease AIMost Canadian retailers leave their easiest revenue sitting in abandoned carts. The average cart abandonment rate sits somewhere between 60% and 80%, depending on which industry figure you trust. A fraction of those customers will return on their own. The rest need a reminder.
Abandoned cart recovery emails work. They consistently outperform almost every other automated email sequence in e-commerce. But only if you send them legally, and only if you send them well.
This matters more in Canada than anywhere else, because we have CASL.
What CASL actually requires
The Canada Anti-Spam Legislation is not a suggestion. Violating it costs businesses $1 million per violation for individuals, $10 million for corporations. The law has been in force since 2014, yet every second guide to cart recovery automation ignores it entirely because it was written for a US audience.
Here is what you need before you send a cart recovery email in Canada:
Express or implied consent. Express consent means the customer ticked a box or filled a form that clearly stated they were agreeing to receive commercial electronic messages. Implied consent exists in narrow circumstances, including an existing business relationship—which, for e-commerce, means a purchase within the past two years or an inquiry within the past six months.
Here is what does not count: someone adding an item to a cart and entering their email at checkout. That action alone does not create consent to send marketing emails. CASL calls a cart recovery email a commercial electronic message unless it is purely transactional. A reminder that says "You left something behind" with a link back to the cart is transactional. A reminder that adds "Plus, here's 10% off" is commercial, and requires consent.
An unsubscribe mechanism. Every message needs a working unsubscribe link, clearly labelled, that processes the request within ten business days. You need to honour it across all your lists, not just the cart recovery sequence.
Your mailing address. The physical address where your business can be contacted must appear in every email.
Most small e-commerce businesses fail the first test. They collect an email at checkout, assume that counts as consent, and send a sequence that includes an incentive. That is a CASL violation from the first send.
The consent problem, and how to fix it
If you are collecting emails only at checkout, and not through an opt-in form elsewhere on your site, you have two choices:
One, keep your cart recovery emails strictly transactional. No offers, no discounts, no product recommendations. Just a reminder with a link back to the cart. This is legal without consent, but it converts poorly.
Two, add a visible, unticked checkbox to your checkout flow that asks for consent to send promotional emails. Write it plainly: "Send me exclusive offers and updates." If they tick it, you have express consent. If they do not, you send the transactional reminder only.
The second approach converts better, but only if the checkbox is genuinely optional and clearly worded. Pre-ticked boxes do not count. Burying the consent language in your terms and conditions does not count. It has to be explicit, separate, and unmissable.
Many Shopify themes include a checkout customisation option for this. If yours does not, it is a fifteen-minute fix. Do not skip it.
When not to automate cart recovery at all
If you sell a handful of high-value items and your customer list is small enough that you recognise most of the names, do not automate this yet. Send the follow-ups manually.
Automation makes sense when volume justifies the setup cost. If you are getting five abandoned carts a week, a manual email from the owner will outperform any automated sequence. It takes three minutes to write, it costs you nothing, and it sounds like a human.
I have seen retailers spend $5,000 on an automated cart recovery flow when their average weekly cart abandonment volume would have taken them thirty minutes to handle by hand. That is not efficiency. That is procrastination dressed up as systems-building.
Build automation when the manual version becomes unsustainable. Not before.
What a working cart recovery sequence actually includes
Assuming you have consent and enough volume to justify automation, here is what works:
Email one, one hour after abandonment. A plain reminder. "You left something in your cart. Here is the link." No subject line tricks, no fake urgency. Just clarity.
Email two, 24 hours later. Add context. "Still interested? Here's what you left behind," with product images and a direct link to checkout.
Email three, 72 hours later. Offer help. "Need a hand?" or "Any questions?" This one can include a discount if your margins allow it and if you have express consent, but it is not required. Many customers convert without it.
Three emails is enough. Five-email sequences do not convert meaningfully better, and they annoy people.
The timing matters less than you think. One hour versus two hours for the first send makes no measurable difference. What matters is that the sequence exists, that it is polite, and that it stops when someone completes the purchase or unsubscribes.
What this costs to build
A single email automation workflow costs between $3,500 and $8,000 to build, depending on complexity. That includes the sequence logic, the email design, the integration with your e-commerce platform, and the CASL compliance setup.
If you are already using Klaviyo, Omnisend, or a similar platform, you may be able to build this yourself using their templates. If you are not, the platform subscription will add $20 to $60 per month on top of the build cost.
For most small retailers, the payback period is measured in weeks. A Shopify store doing $30,000 a month in revenue with a 70% cart abandonment rate and a 10% recovery rate on a $90 average order value will recover an extra $1,890 per month. That is $22,680 per year, which justifies a one-time $5,000 build in the first quarter.
But if your volume is low, or if your average order value is under $40, the math changes. Run it before you build.
Ontario retailers may be able to apply 50% of the build cost against the RMPG (Retail Modernization Project Grant), which provides up to $5,000 matched funding for businesses with a physical storefront and 1-50 employees. You cannot combine RMPG with DMAP. If you are outside Ontario, this does not apply. More detail on eligibility is on the Ontario AI grants page.
What to do next
If you are collecting email addresses at checkout but not sending cart recovery emails, start there. If you are sending them without express consent and including promotional content, fix that first. If you are doing it manually and the volume is manageable, keep doing it manually.
