Klaviyo describes itself as a B2C CRM. It keeps customer profiles and activity in one place and uses them to send email and mobile messages. Its AI features for email can draft sections and subject lines, recommend products and predict send times (Klaviyo Email AI).
A hypothetical starting point
The following is a fictional scenario, not a customer story.
Priya runs a small online shop selling loose-leaf tea. She has 180 subscribers. New subscribers receive nothing, and first-time buyers rarely come back. She wants a welcome email and a reorder reminder, and she has two evenings a week for marketing. The tension is specific: a clumsy sentence is a mistake she can fix. A reminder that promises a discount she cannot afford, or an email to someone who never agreed to hear from her, is a mistake she cannot take back. The rest of this profile asks whether Klaviyo fits that problem, and where it needs a person watching.
What is Klaviyo, in plain terms?
It helps to see Klaviyo as three layers, because each one deserves a different level of trust:
- The customer record. Profiles hold signups and shop activity, fed by integrations. Klaviyo lists connections for Shopify, WooCommerce, BigCommerce and Wix, among others (Klaviyo).
- Ordinary automation. Flows, segments, forms and campaigns follow rules you set. A welcome email that goes out when someone subscribes is automation, not AI. It does what you configured, so you test the configuration.
- AI features. These generate drafts, make predictions or adjust delivery on top of the first two layers. Their outputs can vary, so you review them.
Which Klaviyo AI features are documented?
Email AI section drafting
In the drag-and-drop editor you describe a section in words and receive several drafts to pick from. Drafts can mix text, columns, images, products and buttons, styled from your template (Email AI). Klaviyo says this is available to paying customers. It is not listed among free plan features.
AI subject line suggestions
Klaviyo documents an AI subject line generator (Email AI), and the pricing page lists it on the free plan (Pricing). For a very small shop, this is the AI feature you can try without paying.
Dynamic product recommendations
Recommendations are based on each person's browsing and purchase behaviour (Email AI). A shop with few orders gives the feature little to work from, so expect weak suggestions early on.
Smart Send Time and deliverability aids
Smart Send Time predicts when each subscriber tends to engage. Guided warming increases sending volume gradually, and a reputation repair feature aims to lower spam flagging (Email AI).
Predictive analytics and testing
Klaviyo lists forecasts of lifetime value and churn risk, and A/B testing that picks winning variations (Email AI). Read forecasts as estimates to check against your own records, not facts about a person.
The feature page says these AI capabilities come with every paid plan (Email AI). It states no accuracy levels, so this profile makes no claims about output quality.
Who is Klaviyo a good fit for?
It fits consumer businesses that can connect purchase data and already collect contacts with consent: online shops, subscription brands, and physical retailers or venues that capture customer details digitally. It suits a team where one person handles marketing alongside other work and would rather edit a draft than start from nothing.
It is a weaker fit for B2B companies with long, account-managed sales cycles, where a sales CRM usually sits at the centre.
Practical applications across roles
- Founder of an online shop: a welcome email and reorder reminder built as flows, with drafts from Email AI on a paid plan, or hand-written copy plus AI subject lines on the free plan.
- Retail or hospitality operator: a seasonal update sent only to people with a recent purchase, rather than the whole list. This depends on in-store purchases actually reaching Klaviyo, which you should confirm for your till system.
- Customer service lead: reviewing predicted churn risk to choose who gets a personal check-in from a human instead of an automated offer.
- Merchandiser: adding product recommendation blocks to post-purchase emails, then comparing suggestions with what customers actually buy together.
- Operations manager: using guided warming when sending volume is about to rise, so it climbs gradually instead of jumping in one day.
A proposed workflow: welcome and reorder pilot
This is an illustrative plan using fictional data. It is not a product test, and no timings or results are implied. Where the exact Klaviyo setting is not covered by the sources used here, the step says so.
Fictional input: 180 subscribers, a catalogue of 24 teas, a reorder interval the owner believes is about six weeks, and a rule that no email offers more than 10% off.
Plan dependency: 180 profiles sit inside the free plan's profile limit, but Email AI section drafting is documented for paid plans. On the free plan, write step 3 copy yourself and use only the subject line generator.
- Confirm consent and minimise data. Only include people with a recorded opt-in. Aim to bring in only what the flows use: email, signup date, consent status, order dates and products bought. Whether your integration lets you exclude specific fields is not covered here; check your store connection settings.
- Build the rules first. Create a welcome flow that starts on subscription and a reorder flow based on time since last order. The exact trigger and timing options were not verified for this profile; confirm them in Klaviyo's Help Center. Test each trigger with a profile you control.
- Draft with Email AI. Paste the brief below into the section prompt and choose one draft per email. Edit freely.
- Handle missing data. If a profile has no orders, it gets the general welcome without a product block. If the time since last order is unknown, exclude that person from the reminder rather than guess. Build this as a segment condition if your account supports it; otherwise review the reminder list by hand before each send.
- Human approval. The owner reads every email, checks prices, product names, claims and the 10% cap, and approves before anything goes live.
- Run a small pilot. Start the welcome flow for new subscribers. Enrol only eligible purchasers in the reorder pilot, measuring elapsed time from the actual purchase rather than the subscription date. For the fictional six-week interval, observe each purchase cohort for at least six weeks plus a response window chosen in advance before judging reorder results. Track opens, clicks, unsubscribes, spam complaints, reorders from the reminder group and replies to the shop.
- Review against your own records. Compare reorders with the same period before the pilot using shop sales data, not only Klaviyo's attribution. Watch the free plan's monthly send limit as volume grows.
- Stop route. Pause both flows if unsubscribes or complaints pass a threshold you wrote down before launch, if a wrong price or product appears, or if anyone without recorded consent is emailed. Fix the cause, re-approve, then restart.
Sample output (fictional): a welcome email with a short note from the owner, a brewing guide link and one button to the starter set; around week six, a reminder naming the tea last bought, with a recommendation block of two related blends on a paid plan, or two blends chosen by hand on the free plan.
Copyable Email AI section brief
Create a welcome email section for a small online tea shop.
Audience: new subscribers who have not bought yet.
Tone: warm and plain, no hype, no exclamation marks.
Layout: one image at the top, a text block under 80 words,
then one button linking to the starter set.
Do not mention discounts, health benefits or delivery times.
Use the placeholder [PRODUCT NAME] wherever a product is needed.
The last two lines do the most work. They keep unverifiable claims out of the draft and make gaps obvious during review.
What does Klaviyo cost, and what are the limits?
As of 2 November 2026, the free plan covers up to 250 active profiles, 500 email sends a month, $5 of mobile messages a month (region and carrier dependent), $5 of Composer usage a month, and email support for the first 60 days (Pricing). Go over the profile or send limit and further sending stops until the next billing cycle or an upgrade (Pricing).
Numeric prices for paid plans were not verified. The pricing page uses a plan builder, and the plan, billing interval and unit behind its displayed total were not clear. Check the official pricing page with your own profile count. Do not read the free plan as covering every feature in this profile: section drafting is documented for paying customers.
Who should skip Klaviyo?
Wait if you have no consented contact list or no connected sales data, because the AI layer has nothing to work from. Skip it if you sell mainly through account managers. And if nobody can review each draft before it sends, the AI features add risk rather than remove work.
FAQs
Can I send AI drafts without editing them?
You can, but you should not. A draft can sound right and still state a wrong price or an offer you never approved. One named person signs off every send.
Do I need a developer to start?
Often not, if your shop runs on a platform Klaviyo lists. Unusual systems, in-store tills or custom data may need technical help.
How do I know if the pilot worked?
Write your measures and stop thresholds before launch, then judge reorders against your shop's own sales history, not platform-reported revenue alone.
Your next step
Write one line each for the first flow you would run, the data it needs and the person who approves it. Then open the pricing page and decide whether you need paid features like section drafting or can start on the free plan with hand-written copy.
