Shopify Email and Klaviyo overlap on the one job most small stores care about first: sending abandoned checkout, welcome, and post-purchase messages to people who already gave an address. The difference is price structure and depth. One is bundled with the store plan, the other is a separate subscription that grows with the list.
For most small Shopify stores, staying on Shopify’s built-in email is the better call until email is a measurable revenue channel and a specific limitation is costing sales. Switching to Klaviyo pays off under a narrow set of conditions: a list large enough that segmentation matters, flows that need branching logic, and someone who will actually build and monitor them.
The sections below sort the decision condition by condition: switch when, stay when, and what the community reports about the cost.
What Each Tool Costs, as Published (Checked 2026-10-21)
Shopify’s help center states that stores on the Basic, Grow, Advanced, and Plus plans receive 10,000 free emails each month. Past that, the cost is $1 per 1,000 additional emails up to 300,000, dropping to $0.65 per 1,000 above that and $0.55 above 750,000. Abandoned checkout automations are always free and do not count toward the monthly limit. Shopify now brands the product as Shopify Messaging, and its spending threshold covers email, SMS, and WhatsApp combined.
Klaviyo’s pricing page lists a free plan of up to 250 active profiles and 500 email sends per month, with campaigns, flows, and basic segmentation included. The page as retrieved did not display paid-tier prices at specific list sizes, so this article does not quote them. The plan estimator on the official page generates the figure for a given list size.
A worked example using only Shopify’s published rate: a store with 20,000 subscribers that sends four campaigns a month makes 80,000 sends, of which 70,000 are billable at $1 per 1,000, or $70 a month, with abandoned checkout flows excluded. One commenter in r/shopify described Klaviyo as “like $400/mo for 20k subscribers now,” a figure that is a community report rather than a verified price, and it came from a former legacy-rate customer. Even if it is off by a third, the gap at that list size is wide.
The Case for Staying: Where Shopify Email Is Enough
Shopify Email handles the core flows: abandoned checkout, welcome, and post-purchase, through the Marketing > Automations library of prebuilt templates. One r/shopify commenter who works with larger merchants said the built-in tool “works better for them than any other tools like Klaviyo or Mailchimp” for clients doing multiple millions a year, which is anecdotal but shows that revenue alone does not force a switch.
Another r/shopify commenter put the sequencing most plainly:
“Use Shopify’s email app and save yourself $400 a month. Switch to Klaviyo when you can afford a dedicated email marketing staff person who actually knows how to use the data they provide, will give you reports, and will constantly build and monitor the list.”
That staffing condition is the part most switching decisions skip. A powerful platform without anyone building segments is a more expensive version of the same blast email.
A third commenter in the same thread described the pattern behind many wasted subscriptions: “The mistake I see most is switching tools too early instead of fixing fundamentals,” listing unfinished core flows, uncleaned segments, and weak copy and offers. For a store with fewer than a few thousand subscribers, that diagnosis usually applies before any tool limitation does.
The Case for Switching: Four Conditions That Justify Klaviyo
The switch makes sense when at least two of the following hold at once. One alone rarely covers the cost.
Condition 1: Cart recovery needs filtering, not just sending
The strongest argument for a deeper platform shows up in the abandoned cart debate. A store owner in r/shopify asked whether it was worth emailing someone who added a $12 item and left after 30 seconds, versus a $150 cart that reached checkout. Replies split into two camps: send to everyone because “an email is essentially free,” and filter by intent.
The filtering camp had the more specific advice. One reply argued that “treating all abandoned carts the same is usually the problem,” and listed cart value thresholds, checkout depth, session count, and failed payment attempts as signals. Shopify’s free abandoned checkout automation is a single trigger, and the help page reviewed for this article does not describe cart-value or checkout-depth filtering (worth confirming in the admin before paying for a replacement). Klaviyo’s flows are generally built around conditional splits.
Whether that filtering is worth a monthly fee depends on volume. A store with a handful of abandoned checkouts a week gains little. A store with hundreds can recover meaningful revenue by treating a $150 cart differently from a $12 one.
Condition 2: Email design or content needs exceed the built-in editor
An r/shopify commenter who manages email for medium-sized brands said their agency used Shopify Email in the past and called it “often underestimated,” but switched because “you couldn’t display the abandoned item in a cart abandonment email flow.” Another commenter found the designs “too basic.”
These reports may be dated, since a different commenter said Shopify “really stepped up their game recently” with the Messaging rebrand and an expanded automations library. Anyone considering a switch for design reasons should test the current editor before paying for an alternative, because this is the claim most likely to have changed.
Condition 3: Email and SMS need to work from one customer record
Stores that run SMS alongside email want shared segments and coordinated timing. Shopify has added SMS to its built-in tool, but Klaviyo and several middle-tier platforms are generally regarded as deeper on cross-channel segmentation, though that comparison was not tested for this article. The tradeoffs between SMS options are covered in the best Shopify SMS app breakdown for small stores.
Condition 4: Behavioral data drives revenue decisions
Product-viewed triggers, repeat-purchase logic, and tying email into paid traffic audiences are where a data-heavy platform pays back. Without a person who reads those reports, the data goes unused. The same threshold logic applies to other tools priced for catalogs larger than a small store’s, as the Prisync worth-it analysis shows for repricing.
Switch-When, Stay-When Summary
| Situation | Better call |
|---|---|
| Under a few thousand subscribers, core flows not finished | Stay on Shopify Email and finish the flows |
| Email under a small share of revenue, nobody owns it weekly | Stay |
| Hundreds of abandoned checkouts a month, mixed cart values | Switch, or test a middle-tier option first |
| Need branching flows, product-level triggers, or SMS coordination | Switch |
| Klaviyo cost already high, margins thin | Consider Omnisend, Brevo, or Kit instead |
| 250 active profiles or fewer | Klaviyo free plan costs nothing, so trial it alongside |
The middle row matters because the choice is not binary. Commenters in r/shopify named Omnisend, Brevo, MailerLite, Kit, and Redo as mid-priced options, and a head-to-head of the closest rival is in the Omnisend vs Klaviyo comparison for small stores.
The Opinion: Small Sellers Should Not Pay for Complexity They Will Not Use
Email platforms are priced for the brands that can staff them. A one-person store paying a subscription that scales with list size, while sending the same three flows a built-in tool offers free, is funding a vendor’s growth rather than its own. That is the pattern this channel keeps flagging in ecommerce software: tools sold on revenue promises and priced for funded brands.
The counter-argument is real. Another r/shopify commenter said “it pays for itself many times over,” and for stores where email drives a large share of sales that can be true. Even so, the burden of proof sits with the paid tool: a store should be able to name the specific flow or segment it cannot build today and estimate the revenue attached to it.
A reasonable test is a 60-day parallel run. Build the one flow that Shopify Email cannot do on Klaviyo’s free plan if the list fits, compare the recovered revenue against the fee, and decide on the numbers rather than the reputation.
The Counterweight: Deliverability and Spam Fears
Some shoppers dislike these emails regardless of the tool. One r/shopify commenter wrote: “I add to cart just to confirm shipping pricing - if I don’t purchase then I never will. I hate the abandoned cart emails and to me looks desperate and tacky.” That is a reason to filter carts and to surface shipping costs early, not a reason to skip recovery, since the same thread’s most-upvoted replies report real recovered revenue.
This is also where a free built-in flow has a quiet advantage: it is hard to over-email through a template with one trigger. A powerful platform makes over-segmenting and over-sending easier.
Frequently Asked Questions
Is Shopify Email really free?
Stores on the Basic, Grow, Advanced, and Plus plans get 10,000 free sends each month, according to Shopify’s help center (checked 2026-10-21). Beyond that the rate is $1 per 1,000 emails up to 300,000, and abandoned checkout automations are free and do not count toward the allowance.
What does Klaviyo’s free plan include?
Klaviyo’s pricing page lists up to 250 active profiles and 500 email sends per month, with flows, campaigns, and basic segmentation. Paid tier prices were not displayed in a verifiable form on the page, so the plan estimator should be checked at the store’s actual list size.
Can a store use both Shopify Email and Klaviyo?
Yes, and some merchants keep one tool for flows and the other for campaigns. The cost of running two systems is split attribution and duplicated suppression lists, so it works best as a short migration bridge rather than a permanent setup.
Do abandoned cart emails justify a paid email platform on their own?
Rarely. Shopify’s abandoned checkout automation is free and covers the basic case. The paid platform earns its fee when a store needs to filter carts by value, checkout depth, or product.
The Verdict: Stay Until a Named Limitation Costs Money
Most small Shopify stores should stay on Shopify Email until a specific limitation, such as cart filtering or SMS coordination, can be tied to lost revenue. The switch is justified by a named gap and someone to own the tool, not by the vendor’s reputation. A subscription is only worth its fee once a flow exists that needs it.
