How many emails should a Klaviyo abandoned checkout flow have?

Most ecommerce stores do well with two to three emails. The first sends within one hour of abandonment and focuses on removing friction. The second sends 24 hours later and can include social proof or a small incentive. A third, sent 48 to 72 hours out, works for higher-ticket items where the decision cycle is longer. Do not add more emails just because you can.

Does Klaviyo work with Shopify for abandoned checkout tracking?

Yes, the Klaviyo-Shopify integration tracks checkout abandonment natively. When someone reaches the Shopify checkout and leaves without completing the order, Klaviyo fires a "Checkout Started" event that you use as your flow trigger. The integration also pulls in cart contents, so your email can show exactly what the person left behind, with product images, names, and prices pulled in automatically.

What is the difference between a Klaviyo flow and a campaign?

A campaign is a one-time send to a list or segment, scheduled by you. A flow is an automated sequence triggered by a contact's behavior or profile change. Campaigns work for promotions, newsletters, and announcements. Flows work for welcome series, abandoned checkout, post-purchase, and winback because those need to fire based on what a person does, not when you remember to send.

How long does it take for Klaviyo email flows to generate revenue?

An abandoned checkout flow can generate revenue on its first day if your store has traffic and your Shopify integration is live. Welcome series and browse abandonment flows typically build revenue over one to two weeks as contacts accumulate. Post-purchase and winback flows take longer because they depend on order history. Expect to see meaningful data after 30 days for most flows.

Should I use SMS inside Klaviyo flows alongside email?

For abandoned checkout, adding one SMS after your first email works well for stores where customers have opted into SMS. Send it two to three hours after the first email if the contact has not clicked or converted. SMS is higher-interrupt than email, so use it sparingly inside flows. Do not send SMS and email at the same time. Always honor SMS opt-in status inside your flow filters.

Klaviyo email flows for ecommerce are the closest thing to a store that sells while you sleep. Set them up once, connect them to your Shopify or WooCommerce store, and they fire automatically based on what shoppers actually do.

TL;DR

Klaviyo email flows are behavior-triggered automations, not manual sends. They run 24/7 once you configure them.
The five flows that matter most: welcome series, abandoned checkout, browse abandonment, post-purchase, and winback.
Start with abandoned checkout. It is consistently the highest revenue flow for most stores.
Klaviyo serves over 130,000 brands and is built specifically for ecommerce, which shows in its triggers and segmentation options.

Klaviyo email flows send the right message at the right moment, triggered by shopper behavior rather than a send date. A campaign is a broadcast. A flow is a conversation started by something the shopper did.

Here is the practical difference: if someone adds a jacket to their cart and leaves, a flow catches that. If someone visits your new arrivals page three times in a week and never buys, a flow catches that too. Campaigns cannot do either of those things without a lot of manual work.

Klaviyo connects directly to Shopify, BigCommerce, WooCommerce, and most other major ecommerce platforms. The integration pulls in product data, order history, and browsing behavior, which is what makes the flows feel personal rather than generic. A post-purchase email that names the exact product someone bought converts better than one that says “thank you for your order.” That seems obvious, but you need the integration to make it happen automatically.

The platform also lets you branch flows based on conditions. You can send a different email to first-time buyers than to repeat customers. You can skip a winback email if someone has already placed another order. These branches are what separate a real retention program from a copy-paste email sequence.
