Klaviyo vs Mailchimp 2026: which email platform actually wins for e-commerce
The honest answer: Klaviyo wins when the buying job is “drive Shopify revenue from email and SMS” — direct-to-consumer brands at any stage, operators serious about flow-based revenue, and teams that measure email by attributed sales. Mailchimp wins when the buying job is “send a newsletter and run basic email marketing” — service businesses, B2B newsletters, content creators, and SMBs who do not run an e-commerce store. The two platforms look similar from the outside but solve completely different problems. This guide walks the answer down to a buying decision in 12 minutes.

Pricing note. All numbers above reflect April 2026 published rates and are subject to change. Always confirm on the vendor’s pricing page before buying. Both platforms use contact-based pricing with steep tier jumps — model the price at your projected 12-month subscriber count before committing. Neither offers an annual contract discount in 2026; both are billed monthly with no commitment, which is genuinely buyer-friendly. Klaviyo’s email+SMS bundle at higher contact counts becomes more economical than running Mailchimp + a separate SMS provider.
Who should pick what — and the signals that say you are about to buy the wrong one
You run a Shopify or BigCommerce store and email is meant to drive directly attributable revenue
Klaviyo wins when the buying job is “drive Shopify revenue from email and SMS.” The native integration is the deepest in the category — pulling product catalog, order history, and behavioral data that powers segmentation Mailchimp cannot match. The pre-built flows (welcome series, browse abandonment, cart abandonment, post-purchase, win-back) are revenue-tested templates. For a DTC brand doing $30k+/month, Klaviyo typically pays for itself within 60 days.
Wrong pick if: you are a service business sending newsletters, a B2B SMB without a store, or a content creator with a list under 1,000 subscribers. Klaviyo’s premium pricing only makes sense when revenue attribution justifies the spend.
You send newsletters, run a service business, or want the easiest learning curve in the category
Mailchimp wins when the buying motivation is “send a newsletter and run basic email marketing.” The platform has the gentlest learning curve in the category, the strongest template library, and the most generous free tier (500 contacts forever). The Intuit acquisition added strong integration with QuickBooks, which matters for service businesses that want email tied to invoicing.
Wrong pick if: you run an e-commerce store doing meaningful revenue, you need flow-based revenue attribution, or you plan to add SMS marketing. Mailchimp’s e-commerce features lag Klaviyo’s by several years and the Intuit-era product roadmap has not closed the gap.

Round 1 — Shopify and BigCommerce integration depth
Klaviyo’s e-commerce integration is the reference standard for the category. The native Shopify connector pulls every order, abandoned cart, browse event, product view, and customer attribute into a unified profile that powers segmentation no other platform can match.
BigCommerce, WooCommerce, and Magento integrations ship the same depth. For DTC brands, this single capability is typically worth the entire price difference versus Mailchimp.
- Native Shopify integration — deepest in category
- Real-time order, browse, and behavioral sync
- Product catalog + recommendations native
- BigCommerce, WooCommerce, Magento equally deep
Mailchimp’s Shopify integration was rebuilt after a 2019 dispute ended its native partnership. The current integration covers basic order sync and abandoned cart but lacks the depth Klaviyo ships out of the box.
Custom events, real-time browsing data, and product-level recommendations are either limited or require workarounds. For service businesses or non-store senders, the integration depth does not matter — for DTC operators, it is the difference between $5/email and $0.50/email in attributed revenue.
- Basic Shopify connector — limited depth
- Order + abandoned cart sync only
- No real-time behavioral data depth
- Sufficient for non-e-commerce senders
Round 2 — Automated flows, customer journey building, and revenue-attributed automation
Klaviyo’s flow library is built around revenue moments — the points in a customer journey where email or SMS most influences a purchase. Browse abandonment, cart abandonment, post-purchase, replenishment, win-back, VIP, and product-specific flows ship as ready-to-use templates pre-wired to Shopify data.
The flow editor displays revenue attribution per flow in real time, so operators can see which automations drive the most $/recipient and optimize accordingly.
- 60+ pre-built e-commerce flow templates
- Real-time revenue attribution per flow
- Native cart, browse, post-purchase triggers
- Conditional splits with e-commerce data
Mailchimp’s Customer Journey Builder is competent and well-designed for general-purpose automation. Welcome series, abandoned cart, and re-engagement flows ship as templates. The depth is sufficient for service businesses and B2B SMBs but lacks the e-commerce specificity Klaviyo ships.
The editor is gentle on the learning curve and the visual design is clean — for first-time automation builders, the UX is more approachable than Klaviyo’s flow editor.
- Customer Journey Builder on Standard tier
- Welcome + cart + re-engagement templates
- Cleaner UX for beginners
- Less e-commerce specificity
Round 3 — Audience segmentation, dynamic segments, and behavioral targeting
Klaviyo’s segmentation engine is the most flexible in the email category. Build a segment for ‘customers who purchased Product X in the last 60 days but have not opened an email in 14 days, predicted CLV above $200’ — and the segment evaluates in real time, updating as profiles change.
The unlimited segment depth, combined with predictive analytics fields (CLV, next-order date, churn risk), is what enables the per-segment revenue attribution that drives the platform’s ROI claims.
- Unlimited segment depth — any combination
- Predictive properties native (CLV, churn, next-order)
- Real-time segment evaluation
- Custom event-based targeting
Mailchimp’s segmentation works for most general-purpose use cases. The Standard tier unlocks behavioral targeting and predictive segmentation, but the segment builder is structurally less flexible — fewer condition types, less custom event data, and no native CLV-based segmentation.
For service businesses and B2B SMBs sending broadcast emails, Mailchimp’s segmentation is sufficient. For DTC brands building flow-based revenue, it leaves significant money on the table compared to Klaviyo.
- Behavioral targeting on Standard tier
- Limited custom event support
- No native CLV segmentation
- Sufficient for broadcasts, limiting for flows
Round 4 — Native SMS marketing, deliverability, and unified inbox
Klaviyo’s SMS is genuinely native — not bolted on. Available in U.S., Canada, U.K., Australia, New Zealand (with select EU countries in 2026), with full feature parity to email: same segmentation, same flow editor, same A/B testing, same attribution reporting.
For DTC brands, the unified email + SMS bundle replaces the need for a separate Postscript or Attentive subscription. The economics typically favor consolidation when SMS volume crosses 5,000+ messages/month.
- Native SMS in 6+ countries
- Full feature parity with email
- Unified flows: email + SMS in same automation
- Replaces Postscript/Attentive for consolidation
Mailchimp’s SMS is a basic add-on capability via Twilio integration, available only in the U.S. and U.K. as of April 2026. The feature set is limited — basic transactional and marketing SMS without the workflow depth, segmentation parity, or attribution that Klaviyo ships.
For service businesses with light SMS needs, the integration suffices. For DTC brands building SMS as a primary revenue channel, Mailchimp is structurally not the right platform.
- Twilio-based add-on SMS
- U.S. and U.K. only
- Limited workflow integration
- Functional, not category-leading
Round 5 — Email editor experience, template library, and design flexibility
Klaviyo’s email editor improved substantially in 2025 and 2026 — cleaner interface, better mobile preview, and e-commerce blocks (product feed, recommended products, dynamic coupon) that pull live data from the connected store.
Where it falls short: the template library is smaller than Mailchimp’s, and the design flexibility for non-e-commerce use cases (newsletters, brand storytelling) lags behind. For DTC brands, the e-commerce blocks compensate — for content creators and B2B newsletter senders, Mailchimp’s editor is more pleasant.
- E-commerce-specific dynamic blocks
- Live product feed in editor
- Improved 2026 editor UX
- Smaller template library than Mailchimp
Mailchimp’s template library is the largest and most diverse in the category — 100+ templates covering newsletters, announcements, e-commerce, events, and more. The drag-drop editor is genuinely the friendliest in the market for non-designers.
The Creative Assistant (AI design tool, free across all tiers) generates branded templates from any uploaded logo and color palette in seconds. For teams without an in-house designer, this remains a meaningful Mailchimp advantage.
- 100+ template library — broadest available
- Most beginner-friendly drag-drop editor
- Creative Assistant AI design tool free
- Better for non-e-commerce senders
Round 6 — Inbox placement, sender reputation tools, and deliverability infrastructure
Klaviyo’s deliverability infrastructure is robust, with built-in tools for sender reputation monitoring, list health scoring, and deliverability diagnostics. Dedicated IP options are available on higher contact tiers, and the platform actively guides operators toward authentication best practices.
Inbox placement rates in 2025-2026 third-party deliverability testing show Klaviyo at 92-94% inbox placement to major U.S. providers (Gmail, Yahoo, Outlook) for properly authenticated senders.
- Built-in sender reputation monitoring
- Dedicated IP available on higher tiers
- 92-94% inbox placement (authenticated)
- Active deliverability guidance in product
Mailchimp’s deliverability infrastructure is mature and battle-tested — the platform sends billions of emails monthly and the IP infrastructure is well-managed. Inbox placement rates are comparable to Klaviyo, typically 91-94% in third-party testing for authenticated senders.
Where Mailchimp falls slightly behind: less proactive sender reputation guidance in the product UI, and dedicated IPs are reserved for Premium tier ($350+/mo).
- Mature billions-of-emails infrastructure
- 91-94% inbox placement (authenticated)
- Dedicated IP on Premium tier only
- Less proactive sender guidance in UI
Round 7 — Revenue attribution, performance reporting, and analytics depth
Klaviyo’s reporting is built around revenue, not engagement. Every campaign and flow shows attributed revenue in real time — $/recipient, $/click, total revenue, and lifetime revenue per flow. The benchmarks dashboard compares your performance to other Klaviyo brands in your industry vertical.
For DTC operators, this single capability transforms email from a ‘channel we run’ into a ‘measurable revenue line item’ — and is the primary reason DTC CFOs approve the higher Klaviyo spend over Mailchimp.
- Real-time revenue attribution per send
- $/recipient, $/click, lifetime revenue per flow
- Vertical-specific benchmarks dashboard
- CFO-defensible revenue reporting
Mailchimp’s reporting focuses on engagement metrics — opens, clicks, unsubscribes, and audience growth. Revenue attribution exists but is shallower for e-commerce — and the e-commerce reporting depends on the basic Shopify integration covered in Round 1.
For service businesses and content creators, engagement-focused reporting is appropriate and useful. For DTC brands, the revenue attribution gap versus Klaviyo is structural.
- Engagement-focused reporting
- Shallower revenue attribution
- Limited e-commerce dashboards
- Sufficient for non-store senders
Round 8 — AI features, predictive analytics, and personalization depth
Klaviyo’s predictive analytics are purpose-built for e-commerce: predicted CLV, churn risk score, predicted next-order date, average order value forecast. These predictions become native segment dimensions — operators can build a ‘high-CLV at-risk customer’ segment in seconds.
Klaviyo AI (rolled out 2024-2025) layers on content generation: subject lines, segments-from-prompt, and email copy. The combination of predictive ML plus generative AI is the strongest in the e-commerce email category.
- Predicted CLV, churn, next-order date
- Predictive properties native in segments
- Klaviyo AI for content + segments
- E-commerce-specific ML investment
Mailchimp’s Intuit Assist AI features include subject line generation, content suggestions, and audience optimization. The AI is competent and the integration with the rest of Intuit’s product family (QuickBooks, TurboTax) opens cross-product workflow opportunities.
Where it falls short: the AI is general-purpose rather than e-commerce-specific, and the predictive ML for customer behavior lags Klaviyo’s depth.
- Intuit Assist for content + suggestions
- Audience optimization native
- General-purpose AI focus
- Less e-commerce predictive depth
Round 9 — Onboarding experience, learning curve, and time-to-first-revenue
Klaviyo’s learning curve is real — the segmentation depth and flow complexity that make the platform powerful also make it intimidating to first-time email operators. Plan for 3-4 weeks of active learning before reaching confident workflow.
The platform’s onboarding has improved through 2025-2026: in-product setup wizards, free certification courses, and a strong guided onboarding path for Shopify migrations. For committed DTC operators, the ramp pays off.
- 3-4 weeks to confident usage
- Strong free certification courses
- Improved 2026 in-product onboarding
- Steep but rewarded learning curve
Mailchimp’s onboarding is the gentlest in the email marketing category. The product is genuinely designed for someone who has never sent a marketing email before — clean dashboard, friendly tooltips, and a UX that does not punish exploration.
Operators can typically send a first campaign within 30 minutes of signup. For service businesses, content creators, and beginners, this onboarding advantage is real and meaningful.
- First campaign in 30 minutes
- Friendliest UX in category
- Strong free knowledge base + courses
- Beginner-optimized product design
Round 10 — Total cost of ownership at scale, including SMS and migration economics
Klaviyo’s pricing is higher per contact than Mailchimp at every scale. At 1k contacts: $45/mo vs Mailchimp’s $20/mo. At 10k contacts: $150/mo vs $100/mo. At 50k contacts: $720/mo vs $385/mo.
The defensible answer to the price gap is revenue attribution — for DTC brands, Klaviyo typically delivers 30-40% of total revenue attributed to email + SMS, often 3-5× the rate for the same brand on Mailchimp. The price-per-contact comparison misses the revenue-per-dollar comparison.
- Higher per-contact pricing across all tiers
- $45/mo at 1k, $150/mo at 10k, $720/mo at 50k
- Email + SMS bundle reduces SMS cost
- Justified by revenue attribution gap
Mailchimp’s raw pricing is meaningfully cheaper at every contact tier. Standard at 1k contacts: $20/mo. At 10k: $100/mo. At 50k: $385/mo. The Free tier (500 contacts) is the most generous in the category.
For service businesses, B2B newsletters, and non-revenue-attributed senders, this price advantage compounds — saving $300-$500/month versus Klaviyo at mid-tier scale. The savings only matter when the missing revenue attribution is not the deciding factor.
- Cheaper at every contact tier
- Most generous free tier
- $300-500/mo savings at mid-scale
- Wins for non-attribution buyers
The full scorecard: who won each round, what the tally means, and why the tally lies
| Round | Category | Winner | Why this round mattered |
|---|---|---|---|
| Round 1 | E-commerce Integration | Klaviyo | The single biggest gap — DTC migration trigger |
| Round 2 | Flows & Automation | Klaviyo | 60+ revenue-tested e-commerce templates |
| Round 3 | Segmentation Power | Klaviyo | Unlimited depth + predictive properties |
| Round 4 | SMS Marketing | Klaviyo | Native vs Twilio add-on — not close |
| Round 5 | Email Editor & Templates | Mailchimp | Largest template library + friendliest editor |
| Round 6 | Deliverability | Tie | Both 91-94% — depends on your auth setup |
| Round 7 | Reporting & Attribution | Klaviyo | Real-time revenue attribution per send |
| Round 8 | AI & Personalization | Klaviyo | E-commerce predictive ML (CLV, churn) |
| Round 9 | Onboarding & UX | Mailchimp | Friendliest learning curve in category |
| Round 10 | Pricing Economics | Mailchimp | Cheaper raw pricing at every tier |
The 8-business-type decision matrix: pick by what your business actually does
How three real businesses chose between Klaviyo and Mailchimp — and what the cost math looked like
Bootstrapped Shopify brand: $40k/mo, 4,500 subscribers
U.S. skincare brand, 18 months in, growing 12% MoM. Email previously on Mailchimp Standard, attributing ~8% of revenue ($3,200/mo) — operator suspected money was being left on the table.
Decision: Migrated to Klaviyo Email at $80/mo. Spent 40 hours rebuilding flows over 3 weeks. Added SMS bundle 2 months later.
Total: $135/mo (vs $20/mo on Mailchimp)
B2B service agency: digital marketing, 2,200 newsletter subscribers
U.S. agency running a weekly client newsletter and occasional sales emails. No e-commerce store. Email is brand presence and lead nurture, not direct revenue attribution.
Decision: Stayed on Mailchimp Standard. Considered Klaviyo, ruled out — no e-commerce data to leverage, premium pricing not justified.
Zapier (free tier for CRM sync)
Total: $35/mo
Scaling DTC brand: $300k/mo, 38,000 subscribers
U.S. apparel brand, 4 years old, expanding into wholesale. Email already on Klaviyo Email at 25k contacts. Operator considering “consolidation” to a cheaper platform to cut costs after the apparel category softened.
Decision: Modeled Mailchimp at 38k contacts ($340/mo Standard) vs Klaviyo Email + SMS ($720/mo). Stayed on Klaviyo — revenue attribution at 35% of monthly revenue made the platform price irrelevant.
(vs Mailchimp Standard — $340/mo)
Total: $720/mo
The real switching cost: 30-60 hours of operator time, lost flow data, and the lock-in grade per platform
| Migration cost dimension | Klaviyo lock-in | Mailchimp lock-in |
|---|---|---|
| Contact list export | Low · CSV export native, full profile data | Low · CSV export native, audience-by-audience |
| Flow / journey rebuild | High · 30-60 hours to rebuild 10-15 flows | Medium · 15-30 hours to rebuild journeys |
| Segment recreation | High · Predictive properties do not export | Medium · Behavioral data partial export |
| Template migration | Medium · HTML export possible, rebuild needed | Medium · HTML export possible, rebuild needed |
| Historical revenue attribution | High · Lost on migration — cannot transfer | Medium · Engagement history transfers |
| Free migration assistance | Low · Klaviyo provides free white-glove | Medium · Self-serve migration only |
| Subscriber re-confirmation needed | Low · No re-confirmation typically required | Low · No re-confirmation typically required |
| SMS subscriber migration (TCPA) | High · TCPA consent must be re-collected if records incomplete | Low · Limited SMS volume to migrate |
The six most expensive Klaviyo vs Mailchimp mistakes — and how to avoid them
Picking Mailchimp for a Shopify store because the price is cheaper
Most common e-commerce mistake. The $25/mo savings versus Klaviyo Email looks attractive at signup. Six months later, the operator realizes email is attributing 8% of revenue instead of 25-35% — a $5,000-$15,000/mo gap on a moderately-sized store.
Picking Klaviyo for a service business with no e-commerce
Reverse mistake. Operator reads “Klaviyo is the best email platform” and signs up despite running a B2B agency or service business. Pays 2-3× Mailchimp pricing for features they will never use — predictive CLV, abandoned cart, product recommendations.
Migrating without parallel-running for 60 days
Operator decides to migrate from Mailchimp to Klaviyo (or vice versa), cancels old platform immediately on signup. Loses access to historical engagement data mid-rebuild and ends up paying for both anyway after a panic re-subscribe.
Underestimating flow rebuild time when migrating
Operator thinks “I will migrate over a weekend.” The reality: 30-60 hours of operator time to rebuild 10-15 flows, recreate segments, redesign templates, and validate authentication. Migration drags on for weeks.
Not authenticating SPF, DKIM, DMARC before launching
Equal-platform mistake. Operator signs up, imports list, sends first campaign — and lands 60% of emails in spam because SPF/DKIM/DMARC records are not configured. Sender reputation takes weeks to recover.
Treating SMS as a free Klaviyo add-on instead of pricing it separately
Operator adds Klaviyo SMS expecting free messages because “it is bundled.” Reality: SMS credits are metered separately at ~$0.015/SMS in the U.S. — a list of 5,000 subscribers receiving 4 messages/month costs ~$300/mo just in SMS credits.
The 15 most-searched questions about Klaviyo vs Mailchimp in 2026
Is Klaviyo better than Mailchimp for Shopify?
Yes, for any Shopify store doing meaningful revenue. Klaviyo’s native Shopify integration is the deepest in the email category — pulling product, order, browsing, and customer data that powers segmentation Mailchimp cannot match. For DTC brands doing $30k+/month, Klaviyo typically attributes 25-35% of revenue to email + SMS versus Mailchimp’s 5-10%. The price premium ($25-50/mo more) pays back in days for stores at meaningful scale.
Can I switch from Mailchimp to Klaviyo without losing my list?
Yes. Mailchimp allows native CSV export of all contacts and basic engagement data. Klaviyo offers free white-glove migration assistance for any list above 1,000 contacts — they will rebuild your audiences and import your subscribers without re-confirmation typically required. What you cannot transfer is historical revenue attribution and behavioral segments — those rebuild from new data after migration.
Is Mailchimp still a good email platform in 2026?
For service businesses, B2B SMBs, content creators, and newsletter publishers — yes. Mailchimp’s editor, template library, and onboarding remain the friendliest in the category, and the Standard tier ($20+/mo) is appropriately priced for non-e-commerce use cases. For DTC brands, Mailchimp has structurally lagged Klaviyo since 2019 and the Intuit-era roadmap has not closed the e-commerce gap.
How much does Klaviyo cost vs Mailchimp at 10,000 contacts?
At 10,000 contacts (April 2026 pricing): Klaviyo Email is $150/mo, Klaviyo Email + SMS is approximately $185/mo with a 1,250 SMS bundle. Mailchimp Standard is $100/mo at 10k contacts. The $50-85/mo Klaviyo premium is the relevant cost delta — model that against the email-attributed revenue gap typical for e-commerce stores at this scale.
Does Klaviyo have a free plan?
Yes. Klaviyo Free includes 250 contacts and 500 monthly email sends with full feature access — flows, segmentation, automation. Klaviyo branding appears on emails sent on the free tier. The free tier is genuinely usable for testing the platform or running a very small list — it is not a 14-day trial.
Does Mailchimp have a free plan?
Yes. Mailchimp Free includes 500 contacts and 1,000 monthly email sends — the most generous free tier in the email marketing category. The free tier limits you to 1 audience, 1 user seat, basic templates, and includes Mailchimp branding. Customer Journey Builder and most automation features require Standard tier or above.
Which platform is better for SMS marketing — Klaviyo or Mailchimp?
Klaviyo, by a significant margin. Klaviyo SMS is native — built into the same platform, with full feature parity to email (same segmentation, flows, A/B testing, attribution). Available in U.S., Canada, U.K., Australia, New Zealand. Mailchimp SMS is a Twilio-based add-on with limited workflow integration and U.S./U.K. coverage only. Any DTC brand serious about SMS should pick Klaviyo.
Can I use Klaviyo without Shopify?
Yes, but the value proposition weakens significantly. Klaviyo’s pricing premium over Mailchimp is justified primarily by e-commerce data integration. Without a connected store, you are paying for capabilities you cannot use. Klaviyo without Shopify is overpriced for non-e-commerce email use cases — Mailchimp Standard is the better pick.
What is the deliverability difference between Klaviyo and Mailchimp?
Functionally negligible. Both platforms ship mature deliverability infrastructure with 91-94% inbox placement in third-party testing for properly authenticated senders. Klaviyo edges slightly ahead on built-in sender reputation tools and dedicated IP availability, but deliverability outcomes are 80% determined by your authentication setup (SPF, DKIM, DMARC) — not by the vendor.
Is Klaviyo or Mailchimp better for small business?
It depends on what kind of small business. Small e-commerce stores → Klaviyo Free or Email tier. The native Shopify integration delivers more revenue per dollar than Mailchimp at any small business scale. Small service businesses, B2B SMBs, agencies, or newsletter publishers → Mailchimp Free or Standard. The friendlier UX and broader template library serve non-e-commerce use cases better.
Does Klaviyo work with WooCommerce and BigCommerce?
Yes. Klaviyo’s WooCommerce and BigCommerce integrations are structurally as deep as the Shopify integration — pulling product catalog, order data, customer attributes, and behavioral events natively. Magento (Adobe Commerce) is also fully supported. The platform was built e-commerce-first and supports the major platforms with feature parity.
What happens to my Mailchimp automations when I switch to Klaviyo?
You rebuild them. Mailchimp’s Customer Journey Builder structures and Klaviyo’s Flow editor are not interchangeable — automations cannot be exported and imported. Plan for 30-60 hours of operator time to rebuild 10-15 flows. Klaviyo’s free white-glove migration team can rebuild the most common flows (welcome, abandoned cart, post-purchase) for you as part of migration.
Which platform has better AI features in 2026?
Different strengths. Klaviyo AI is stronger for e-commerce predictive ML — predicted CLV, churn risk, next-purchase date, and replenishment timing. Mailchimp’s Intuit Assist is stronger for general-purpose content generation — subject lines, content suggestions, audience optimization. For DTC brands, Klaviyo’s predictive AI is more valuable; for newsletters and service businesses, Mailchimp’s content AI is more useful.
Does Klaviyo or Mailchimp integrate with Salesforce?
Both integrate with Salesforce, but the integrations target different use cases. Klaviyo’s Salesforce integration is e-commerce-focused — syncing customer data, orders, and revenue attribution. Mailchimp’s Salesforce integration is contact/lead-focused — syncing audiences and basic engagement. For B2B teams running Salesforce as the primary CRM, neither platform is the natural choice — see our ActiveCampaign vs HubSpot comparison for marketing automation alternatives.
Which platform should I pick if I am completely new to email marketing?
Mailchimp, almost always. The onboarding is the friendliest in the category, the template library lets non-designers ship quickly, and the free tier (500 contacts) supports learning without billing pressure. The exception: if you are launching a Shopify store and email + SMS will be central to the business model, start on Klaviyo Free — even with the steeper learning curve, you avoid migrating later when revenue scales.
