11 Best Email Marketing Platforms for Ecommerce in 2026: Store Sync, SMS and Real Costs

For an online store, the best email marketing platform for ecommerce is Klaviyo when Shopify data should drive every flow, Omnisend when email, SMS and push belong in one builder, Shopify Messaging when you want to start free, and Brevo when a big list mails rarely. The billing unit moves the bill most: Klaviyo charges by active profile, Omnisend and Mailchimp by contact, and Brevo, Sendlane and Shopify Messaging by emails sent.

I built this ranking from the vendors’ pricing, help and integration pages, read on November 2, 2026, and priced one example store at four list sizes. If you do not sell online, my full email marketing platform ranking covers general picks.

Read the billing column first: two stores with the same list can pay very different bills depending on whether the tool counts people or sends.

How I Chose the Best Email Marketing Platforms for Ecommerce

A platform made the list only if its own pages document a store integration and prebuilt automations for store events such as an abandoned cart or checkout.

I ranked the 11 picks by six criteria, in order: store data the tool syncs, prebuilt store flows and the plan that holds them, billing unit and cost at a real list size, SMS and push in the same tool, store platforms supported, and a no-cost start to test the sync. My guide to how marketing automation works explains flows and triggers.

I also compared reporting and AI features plan by plan; the Klaviyo, Omnisend and ActiveCampaign sections below name the plan that holds each.

I considered 17 tools: the 11 picks below and Drip, Attentive, GetResponse, HubSpot, Constant Contact and Kit, which sit under Also Considered. Prices, limits and integrations come from the vendors’ pricing pages, help centers and integration pages, read on November 2, 2026; the “best for” labels are my judgment of those facts.

Software	Store data synced	Prebuilt store flows	Free start
Klaviyo	Profiles, orders, Markets catalogs; data back to Shopify	60+ templates incl. browse abandonment	Free plan
Omnisend	Contact and order data (BigCommerce)	Cart, product abandonment, post-purchase	Free plan
Shopify Messaging	Native to the Shopify admin	Abandoned checkout, welcome, winback	10,000 emails a month
Brevo	Purchase and abandoned cart data (Shopify)	Standard plan workflows	Free plan, 300 emails a day
Mailchimp	Shopify segments, discount codes	Welcome, abandoned cart, back-in-stock	Free plan
Privy	Contacts to Shopify, BigCommerce, Wix	Welcome to win-back templates	15-day trial
Postscript	Shopify data for segments	Cart and browse abandonment, welcome	$100 credit
Sendlane	Deep data: Shopify, WooCommerce	Pre-built automation funnels	60-day trial
ActiveCampaign	Shopify, Square, WooCommerce	Abandoned cart on Starter	14-day trial
MailerLite	Shopify customers and orders	Abandoned cart (Shopify)	Free plan
Moosend	Product views, carts, purchases	Cart abandonment (WooCommerce)	30-day trial

Vendor pages do not show deliverability or how reliably an integration imports years of order history, so connect your store on the free plan or trial of your top two and check that orders and the product catalog arrive before you build a flow. With the criteria set, here is which platform wins each store job.

1. Klaviyo: Best for Shopify Stores That Want the Deepest Store Data in Their Flows

Klaviyo is my pick for a Shopify store that wants every flow to react to what a shopper bought, browsed or left in the cart. Its Shopify guide documents a sync that runs in both directions, and its flow library adds price-drop and predicted-next-order triggers. You pay for that depth per active profile, so each emailable subscriber raises the price whether they buy or not.

The two-way sync is why it ranks first. Klaviyo pulls profiles and order data from Shopify, adds shoppers who accept email or SMS marketing at checkout to a list you choose, and can import Shopify Markets catalogs. In return it can write contact info, subscriptions, email and text events and custom properties back to Shopify, which keeps consent data in one place for any app that reads Shopify customer records.

Two catches: Markets syncing works in one Klaviyo account at a time, and the Viewed Collection, Submitted Search and Added to Cart events need Shopify Network Intelligence turned on, or flows built on them may not trigger.

Klaviyo lists 60+ pre-built flows, including welcome, abandoned cart, browse abandonment, post-purchase, price drop and back-in-stock, and one flow can mix email, SMS and push. Post-purchase splits by order count, so a replenishment brand can treat a first order and a fifth order differently without building that personalization from scratch. Omnisend covers the core cart and post-purchase flows too; Klaviyo’s edge is the predictive and price-drop triggers.

Reporting and AI follow the plan ladder. The free plan includes reports and dashboards, generative AI for subject lines and $5 of Composer usage a month; Email adds audience and conversion dashboards. Predictive analytics and marketing and segment performance reports sit on the Marketing plan, an estimated $170 a month at 5,000 profiles, so a store that wants attribution by segment should price that tier.

One billing lever: profiles suppressed from email do not count toward the limit, so cleaning out unengaged subscribers can keep a store on a lower tier. When you switch tools, Klaviyo says to disconnect the old one from Shopify first, or existing subscribers can get double opt-in emails.

Choose Klaviyo when your store runs on Shopify and you plan to segment by order count, product and browsing from the first month. For the whole platform beyond store flows, read my Klaviyo review.

Skip it if:

your list is large, mostly unengaged and mailed only a few times a month. Sendlane bills by sends with unlimited profiles, so a dormant subscriber costs nothing until you email them. Brevo prices by email volume, and each tier carries a contact allowance: 500 contacts at 5,000 emails, 2,500 at 15,000 and 500,000 at 50,000.

2. Omnisend: Best for Email, SMS and Web Push in One Builder

Omnisend fits a store that wants text messages and browser push in its cart and post-purchase flows without paying for a second app. One builder combines email, SMS and push, and unlimited web push starts on Standard. Sends on Standard top out at 12 times your list size a month, and SMS credits come with Pro, so a store that texts every week should price Pro from the start.

One workflow can move a shopper from an email to a text to a push notification, and Omnisend’s templates cover welcome, product abandonment, cart abandonment, order and shipping confirmation and cross-sell. Next to Klaviyo, the difference is how texts are sold: Omnisend sells US SMS credits in volume bands, from $0.009 per message for a $10 to $49.99 purchase down to $0.007 at $10,000 or more.

Switching help is the other draw. Omnisend’s team moves lists, segments, flows and templates for free within 5 days and says it rebuilds abandoned cart, post-purchase and win-back flows for stores coming from Klaviyo. Live chat and email support run 24/7 on every plan, including Free. Omnisend markets itself to Shopify stores, and its BigCommerce app syncs contact and order information automatically.

Reporting and AI lean toward Pro. Omnisend’s FAQ names advanced reporting among the reasons stores pick Pro over Standard, and the Pro card lists the product recommender agent, which inserts products into each email from browsing and purchase behavior.

Read the billing rule twice: Omnisend bills subscribers and non-subscribers who received automated messages, so order confirmations sent through it count buyers who never opted into marketing.

Omnisend assigns a free account expert to anyone paying at least $400 a month; smaller stores rely on the 24/7 live chat and email support that every plan includes.

Choose Omnisend when SMS supports your email program rather than leading it and you want one tool. Move to Pro once texts or daily sends matter.

Skip it if:

text messages drive most of your revenue and you want SMS-specific options such as a dedicated short code; Postscript is built around that channel.

3. Shopify Messaging: Best for New Shopify Stores That Want to Start Free

Shopify Messaging, the app formerly known as Shopify Email, is where a new Shopify store should start before paying anyone, while the plans behind it are priced in my Shopify pricing guide. Every month includes 10,000 free emails, abandoned checkout emails never count toward that allowance, and email, SMS and WhatsApp campaigns run from the Shopify admin. It works only for Shopify stores, and its automation pages name welcome, winback and upsell templates and abandoned checkout, while Klaviyo’s flow page also names browse abandonment and price drop.

Billing by sends rather than contacts suits a young store. Automations count toward the 10,000 free emails, except abandoned checkout emails, unused emails do not carry over, and a monthly spending threshold sends an alert once combined email, SMS and WhatsApp costs reach the amount you set.

Automations fire on actions such as abandoning a cart or signing up for the newsletter, and Shopify lists ready-made welcome, winback and upsell templates. By default they reach only customers subscribed to that channel. On SMS, a long message is billed as several, and confirmation and double opt-in texts are billed too. Where Klaviyo’s free plan stops at 250 profiles, Shopify counts emails, not people.

Start here if your store is new on Shopify; move to Klaviyo or Omnisend once you want segments built on browsing and order history.

Skip it if:

your store runs on WooCommerce or BigCommerce; Klaviyo, Omnisend, Mailchimp and Brevo document both, and ActiveCampaign supports BigCommerce on Pro.

4. Brevo: Best for Large Lists That Send Less Often

Brevo makes the most sense for a store whose list is large but whose sending calendar is light. Plans are sized by monthly email volume, and the contact allowance grows faster than the sends: the 50,000-email Starter tier includes 500,000 contacts. Starter has no marketing automation, though, so automated workflows start on Standard.

Brevo builds its own Shopify and WooCommerce integrations, and the Shopify app syncs purchase data and abandoned cart details to trigger recovery messages. Standard adds multi-step workflows, A/B testing and web and event tracking. Transactional email comes with every plan, so order confirmations can share the account.

The channel list is wide but tiered. SMS credits are sold separately, while WhatsApp and pop-ups sit on Professional, which starts at 150,000 emails a month. A store that wants web push at a small send volume gets it on Omnisend’s Standard plan instead.

Choose Brevo when your list is far bigger than your sending calendar. My Brevo pricing breakdown covers every volume tier.

The broader platform, including its CRM, is in my Brevo review.

Skip it if:

you email your list several times a week; Omnisend Pro, with unlimited emails, keeps the bill flat as frequency rises.

5. Mailchimp: Best for Stores That Run General Marketing Alongside Store Flows

Mailchimp suits a store that also runs general marketing and wants its Shopify or WooCommerce data inside one familiar tool. The Shopify integration syncs segments, pushes unique discount codes back to Shopify and triggers welcome, abandoned cart and back-in-stock automations. Expect the price to rise with contacts, and the store features that matter most sit on Standard rather than Essentials.

Discount-code sync earns the place. Single-use codes created in Mailchimp sync to Shopify so customers can redeem them, in email, SMS and pop-up forms, and attributed campaign revenue shows in the Shopify dashboard. WooCommerce stores get customer and order data, abandoned cart reminders and post-purchase campaigns through Mailchimp’s own integration.

The gates decide the purchase. Marketing Automation Flows run only on paid plans, and predictive segments and dynamic content need Standard or Premium. SMS is a paid-plan add-on whose credits expire monthly, where Privy’s roll over.

Choose Mailchimp when one team sends store flows, newsletters and event invitations from one tool. The full verdict is in my Mailchimp review.

Skip it if:

store flows are your whole email program; Klaviyo or Omnisend build around store data from the free plan up.

6. Privy: Best for Growing a Store’s List With On-Site Pop-Ups

Privy belongs on the list for a store whose bottleneck is list growth rather than flow logic. Its Email plan, from $30 a month with unlimited email sends, pairs email and SMS campaigns with advanced pop-up design and targeting. Depth is where it gives ground: its flows run from welcome to win-back on templates, and its pages describe syncing collected contacts to Shopify, BigCommerce or Wix.

The Pop-ups & Displays only plan is the useful twist. From $24 a month, priced by page views, it lists spin-to-win, cart saver and exit-intent pop-ups, collects contacts and syncs them to Shopify, BigCommerce or Wix and to select tools, including Klaviyo, so a Klaviyo store can keep its flows and use Privy only for capture.

On the full plan, contacts are billed only when mailable and sends are unlimited, so mailing more often does not raise the bill. Privy also now owns Sendlane, according to the banner on Sendlane’s pricing page.

Choose Privy when a small store needs subscribers before it needs complex flows, or put its pop-ups-only plan in front of Klaviyo.

Skip it if:

your list already grows and the gap is flow logic; Klaviyo’s browse abandonment and predictive triggers do more with the subscribers you have.

7. Postscript: Best for SMS-Led Shopify Brands

Postscript is the pick when texts, not email, are the channel a Shopify brand plans around. It charges per message with no profile fees, segments on Shopify data, and includes cart abandonment, browse abandonment, welcome and upsell templates on every plan. The trade-off is a second tool: Postscript calls itself an SMS, RCS and email platform, but its pricing page puts email behind a waitlist.

The plan choice is a volume question. Growth’s rate is $0.001 per SMS lower than Starter’s, so its fee pays back at 100,000 messages a month: Starter costs 100,000 x $0.009 = $900 and Growth $100 + 100,000 x $0.008 = $900. Professional’s higher fee pays back only at 400,000 messages. Carrier fees sit on top: at the average US SMS fee Postscript lists, 100,000 texts add 100,000 x $0.0033 = $330.

Postscript assigns and verifies a dedicated toll-free number for free, while a dedicated short code costs $750 a month through the carriers. Contracts are optional; without one, billing is monthly.

Choose Postscript when SMS revenue justifies its own platform; my comparison of SMS marketing platforms covers the SMS-only alternatives.

Skip it if:

texts are a side channel to email; Omnisend Pro or Klaviyo’s per-send SMS keep both channels in one flow.

8. Sendlane: Best for Large DTC Lists That Want to Pay by Sends, Not Profiles

Sendlane suits a store with a big customer file that wants the bill tied to sends, not to the people it keeps. Profiles are unlimited, the entry tier covers 50,000 emails a month, and its data integrations reach Shopify, WooCommerce and Smile.io. Two things to weigh: dedicated support and program reviews are reserved for annual contracts, and Sendlane’s pricing page now carries a banner saying Sendlane has been acquired.

The billing model is the reason to look. A store with 10,000 contacts mailing each one five times a month sends 50,000 emails, which fits Sendlane’s entry tier at a lower price than Klaviyo’s $150 for 10,000 profiles. At 5,000 profiles Klaviyo’s Email plan shows an estimated $100 a month, the same as Sendlane, and at 2,500 profiles Klaviyo is $60, so smaller lists pay less on profiles. Sends over the tier cost $2.00 per thousand.

Sendlane lists deep data integrations for Shopify, WooCommerce, ClickBank, Miva and Smile.io, plus pre-built automation funnels and website tracking on every plan. Its SMS credit price includes carrier fees, which makes a text budget easier to read than Postscript’s rate plus pass-through fees; SMS needs a paid account.

Choose Sendlane once your list grows past 5,000 profiles: Klaviyo’s Email plan is an estimated $100 a month at 5,000, the same as Sendlane, and $150 at 10,000.

Skip it if:

your list is under a few thousand people; Klaviyo’s tier at 2,500 profiles or Shopify Messaging’s free allowance costs less.

9. ActiveCampaign: Best for Stores That Also Need a Sales CRM

ActiveCampaign is the pick for a store that also runs a sales pipeline, such as wholesale accounts, and wants automation and CRM in one system. Abandoned cart and the Shopify, Square and WooCommerce integrations come on every plan, Starter included. Its plan gates decide the price more than the contact count does.

BigCommerce, Magento and Shopify Plus are premium integrations on Pro and Enterprise only, so a BigCommerce store’s real entry price is Pro’s, not Starter’s. Product catalog blocks and coupons start on Plus at $49 a month billed yearly. SMS is an add-on that works with Plus, Pro and Enterprise but not Starter.

The CRM side is an add-on too: Enhanced CRM, with pipelines and sales engagement, is available from Plus. For a store that only sells online, that is cost without use; for one with a wholesale team, it replaces a second subscription. Reporting is gated the same way: ecommerce reporting and generative AI start on Plus, and revenue attribution needs Pro. If the CRM matters more than email, my list of CRMs built for ecommerce is the better starting point.

Choose ActiveCampaign when email and a sales pipeline need to share one contact record. My ActiveCampaign review covers the automation builder in full.

Skip it if:

you run a store with no B2B pipeline; Klaviyo integrates with Shopify to bring in profile and order data, and its 60+ pre-built flows, including browse abandonment and price drop, are built around store data.

10. MailerLite: Best for Small Stores on a Tight Budget

MailerLite fits a small store that wants Shopify or WooCommerce data in its emails at a low monthly price. Every paid plan gets the full feature set, ecommerce triggers included. What it lacks is SMS on the marketing plans: texting lives in MailerLite’s separate transactional product.

The Shopify integration does more than the price suggests. It syncs customers and subscribers with their order information, builds segments such as first-time customers, high spenders and repeat buyers automatically, imports products into the email editor and sends abandoned cart and purchase-triggered emails. MailerLite also lists a WooCommerce integration and e-commerce sales tracking.

The free plan is real but tight: 250 subscribers, 2,500 emails a month, and 3 active automations of up to 5 steps. Welcome, abandoned cart and post-purchase flows use all three slots on day one, which is the point to move to Comfort’s 50 automations.

Choose MailerLite when your store is small, your flows are simple and the budget is the constraint.

Skip it if:

you want texts in the same tool; Omnisend adds SMS and push to the same flows.

11. Moosend: Best for Product-View Triggers on a Small Budget

Moosend earns its place for a small store that wants to react to product views from day one without Klaviyo’s bill. Its builder has “views any product” and “browses any page” triggers, tracks product views, carts and purchases, and adds AI product recommendations; the WooCommerce integration adds cart abandonment and product recommendation emails. The catch is the start: there is no free plan after the 30-day trial, and its integrations page lists WooCommerce and Magento connectors, so check that your store platform is listed before the trial ends.

Moosend is now a Constant Contact company. Bi-annual billing saves 15%, and nonprofits get 25% off on top of the annual discount.

Choose Moosend when you run WooCommerce on a tight budget and browse-based reminders matter more than SMS.

Skip it if:

you want a free plan to start; MailerLite and Shopify Messaging both have one.

How to Choose an Ecommerce Email Platform

Answer three questions in order: which store platform you run, whether SMS belongs in the same tool, and which billing unit is cheaper at your list size. The matrix narrows the first two.

Software	Shopify integration	WooCommerce integration	BigCommerce integration	Abandoned cart flow	SMS
Klaviyo	Yes	Yes	Yes	Free plan	Add-on per send
Omnisend	Yes	Yes	Yes	Automations on Free	Pay per SMS; bonus credits on Pro
Shopify Messaging	Yes	Not listed	Not listed	Free	Per message
Brevo	Yes	Yes	Yes	Marketing automation from Standard	Credits

Sendlane	Yes	Yes	Not listed	Not listed	Paid plans
ActiveCampaign	Yes	Yes	Pro	Starter	Add-on from Plus
MailerLite	Yes	Yes	Not listed	Yes	Not listed
Moosend	Not listed	Yes	Not listed	Yes	Not listed

“Not listed” means the vendor pages read for this list do not name it, so check the vendor’s integration directory before ruling a tool out.

Start from your store platform

Shopify stores have the most choice: every pick except Moosend documents a Shopify connection. WooCommerce stores should look at Klaviyo, Omnisend, Brevo, Sendlane, ActiveCampaign, MailerLite, Mailchimp and Moosend. BigCommerce stores have Klaviyo, Omnisend, Brevo, Mailchimp and Privy, or ActiveCampaign on Pro, the same gate Shopify Plus stores face there.

Email and SMS in one tool or two

Bundle SMS when it supports email: Omnisend Pro, Klaviyo’s per-send texts and Shopify Messaging keep both channels in one flow and one bill. Use a specialist such as Postscript when SMS drives most of the revenue and plan rates, keywords and a short code option matter.

Each tool prices texts on a different basis: Klaviyo adds carrier fees to its per-send rate, Shopify adds a $2.15 monthly number fee, Sendlane includes carrier fees in its credits, and Postscript passes them through at cost.

Security and compliance belong in the same decision. Shopify Messaging automations reach only customers subscribed to that channel by default, Omnisend’s forms include TCPA and GDPR consent collection, Postscript verifies a dedicated toll-free number for every merchant at no charge, and MailerLite lists ISO 27001 certification and GDPR compliance on its pricing page.

Price it at your list size, not the entry tier

Profile and contact billing favors small, engaged lists; send billing favors big lists that mail less often. Klaviyo’s price follows active profiles, Omnisend’s and Mailchimp’s follow contacts, and Brevo’s, Sendlane’s and Shopify Messaging’s follow emails sent. The next table puts one store through each model.

What Each Platform Costs at 500, 2,500, 5,000 and 10,000 Contacts

Take an illustrative store that mails each contact five times a month, at four example list sizes: 500, 2,500, 5,000 and 10,000 contacts. At five emails per contact it sends 500 x 5 = 2,500, 2,500 x 5 = 12,500, 5,000 x 5 = 25,000 or 10,000 x 5 = 50,000 emails a month. The table prices that store wherever the vendor’s pricing page prints the tier it needs and leaves the other sizes to the vendor’s selector, so swap in your own list size and send count.

Software (billed by)	500 contacts	2,500 contacts	5,000 contacts	10,000 contacts	Assumption
Klaviyo Email (active profiles)	$20	$60	$100	$150	Profile tiers include 5,000, 25,000, 50,000 and 100,000 emails
Shopify Messaging (emails sent)	$0	$2.50	$15	$40	10,000 free, then 2.5 x $1, 15 x $1 and 40 x $1 per 1,000
Brevo Starter, no flows (emails sent)	$9	$25	Set the selector	$56	Billed monthly; 5k, 15k and 50k tiers; flows need Standard, from $18 a month
Sendlane (emails sent)	$100	$100	$100	$100	50,000-email tier, paid monthly
Omnisend (contacts)	$48.00 / 3 = $16	$177.00 / 3 = $59	Set the selector	Set the selector	Standard at 500, Pro at 2,500; 3-month totals shown per month
MailerLite Comfort (subscribers)	$10.80 USD/month, $129.60 billed yearly	$29.70 USD/month, $356.40 billed yearly	$44.10 USD/month, $529.20 billed yearly	$80.10 USD/month, $961.20 billed yearly	Billed yearly; 5,000, 25,000, 50,000 and 100,000 monthly emails at 500, 2,500, 5,000 and 10,000 subscribers

Sources: Klaviyo pricing, Shopify Messaging email pricing, Brevo pricing, Sendlane pricing, Omnisend pricing, MailerLite pricing, checked Nov 2026.

Shopify Messaging stays close to free at every size, and Klaviyo grows with the list. Sendlane’s flat $100 costs more than Klaviyo at 2,500 profiles ($100 against $60), ties with Klaviyo’s estimated $100 at 5,000 profiles and costs less at 10,000 ($100 against $150).

Among the plans with a fixed monthly fee, Brevo Starter is the lowest in every column that shows its tier, but it runs no marketing automation, so treat it as a floor: flows start on Standard.

Moosend prices every list size through a contact selector, as do Omnisend above the tiers shown and ActiveCampaign, whose Starter price at 1,000 contacts is in its own section; the plan each store job needs is there too. Postscript prices texts instead: 10,000 SMS a month cost 10,000 x $0.009 = $90 on Starter before carrier fees.

Also Considered

Each of these fits a store job, but a fact below kept it off the ranked list:

• Drip: built for ecommerce, with a 14-day trial and integrations for Shopify, BigCommerce and WooCommerce; it bills by active people and monthly email volume, and its store job overlaps Klaviyo’s and Omnisend’s. See Drip’s pricing page for the figure at your list size.
• Attentive: an SMS-led platform that prices by message volume, list size, channels and AI products, with a free trial requested through a form; it publishes no list price, so it has no row in the cost table.
• GetResponse: abandoned cart recovery is listed from Marketer, the plan aimed at marketers and ecommerce businesses, at $59 a month, and GetResponse offers a 14-day trial; Creator leans to courses, with up to 500 students.
• HubSpot: Marketing Hub is part of HubSpot’s customer platform and works from its CRM data; its cost is covered in my HubSpot pricing guide.
• Constant Contact: Lite starts at $12 a month, and Moosend’s page says Moosend is now a Constant Contact company; the list keeps Moosend, whose WooCommerce integration runs cart abandonment emails.
• Kit: a creator newsletter platform; my newsletter tools comparison is where it fits.

FAQ

What is the best email platform for e-commerce?

No single platform wins every store job. Klaviyo fits Shopify stores that want flows built on orders and browsing, Omnisend fits email, SMS and push in one builder, Shopify Messaging fits new Shopify stores on a $0 budget, and Brevo fits big lists mailed a few times a month. Pick by store platform and billing unit first.

Why are people leaving Mailchimp?

The pressure points show in Mailchimp’s plan rules. The free plan pauses sending at 250 contacts or 500 sends a month, paid plans bill overages past contact or send limits, and predictive segments need Standard. Compare your contact tier with a send-billed tool such as Brevo before moving.

Can I run ecommerce email marketing for free?

Yes, at small scale. Shopify Messaging includes 10,000 emails a month on Shopify’s paid plans, and Klaviyo, Omnisend, Mailchimp and MailerLite have free plans for up to 250 contacts or subscribers. Klaviyo and Omnisend cap free sends at 500 a month, so a free plan suits testing the store sync more than running a growing program.

Final Verdict

Start with your store platform and your send pattern, then trial two tools side by side.

• Shopify store that wants flows on orders, catalog and browsing: Klaviyo, accepting a bill that grows with every emailable profile.
• Email, SMS and push in one place: Omnisend, on Pro once texts matter.
• New store with no budget: Shopify Messaging, or MailerLite’s free plan off Shopify.
• Big list, light calendar: Brevo on Standard.
• Big list, steady sends: Sendlane once your list passes 5,000 profiles, where Klaviyo’s Email plan reaches the same $100 a month.
• SMS-first brand: Postscript, paired with an email tool from this list.
• Store with a sales pipeline: ActiveCampaign, on Pro for BigCommerce or Shopify Plus.
• Store that also sends general marketing: Mailchimp on Standard.
• List growth first: Privy, alone or in front of Klaviyo.
• Product-view reminders on WooCommerce for little money: Moosend.

Then connect your store to the free plan or trial of your top two and check that orders and products arrive before you build the first flow.
