The best ecommerce marketing tools
Ecommerce marketing tools earn their keep by turning store data into repeat orders. The eight tools below cover email, SMS, popups, reviews, and loyalty, and each one fits a different store size and budget. We compared official pricing pages and feature lists, and we focused on store integrations, automation, and total cost at realistic list sizes.
Klaviyo is the default pick for stores that live on email revenue and want to segment by what customers actually bought, browsed, or ignored. Its flows cover welcome series, abandoned carts, browse abandonment, and post-purchase messages, and its predictive tools flag churn risk and expected lifetime value. The free plan covers up to 250 active profiles and 500 emails a month, while paid email plans start at $20 per month for 251 to 500 profiles.
The cost curve is the honest catch. A store with 10,000 profiles pays around $150 per month for email alone, and SMS adds more. Small stores may find Omnisend cheaper for the same basic flows. Klaviyo earns its premium when you use segmentation, testing, and attribution to drive repeat orders, not when you only send a weekly newsletter.
- Deep segmentation from purchase and browsing data
- Strong Shopify integration
- Large library of prebuilt flows
- Costs rise fast with active profiles
- SMS is priced separately
- Support on the free plan is limited
Omnisend is the value pick for Shopify, WooCommerce, Wix, and BigCommerce stores that want email, SMS, and web push in one place. Its free plan covers 250 contacts and 500 emails a month, and the Standard plan starts at $16 per month for 500 contacts and 6,000 emails. Prebuilt flows for welcome, cart abandonment, and post-purchase messages mean a new store can start earning from automation on day one.
The trade-off is depth. Omnisend handles standard ecommerce automation well, but its segmentation and predictive tools do not match Klaviyo for data-heavy stores. SMS pricing also needs care, since it is usage based and the full SMS setup sits on the Pro plan. For stores that want solid automation at a lower bill, Omnisend is hard to beat.
- Free plan with email, SMS, and push
- Prebuilt ecommerce flows
- 24/7 support on every plan
- Segmentation is less deep than Klaviyo
- SMS on lower tiers needs an add-on
- Reporting is thinner at the top end
Mailchimp remains a good general email tool, and it works for stores that send broadcasts, promotions, and simple abandoned-cart messages. Its free plan covers 250 contacts and 500 emails a month, and Essentials starts at $13 per month for 500 contacts. Templates, scheduling, and basic automation are easy to learn, and the integration library covers most store, CRM, and form tools.
The catch is ecommerce depth and billing. Mailchimp counts contacts in a way that can surprise store owners, and its segmentation does not go as deep as Klaviyo or Omnisend for purchase behavior. Stores that rely on email for a large share of revenue will usually get more from a store-first tool. Mailchimp fits best when email is one channel among many, not the main revenue engine.
- Large template library
- More than 300 integrations
- Easy campaign builder for beginners
- Free plan now covers only 250 contacts
- Ecommerce segmentation is thinner
- Costs rise with total contacts, including unsubscribed ones
HubSpot suits ecommerce teams that also run sales, service, or B2B work and want one CRM behind marketing. Its Marketing Hub covers email, automation, landing pages, and reporting, and it connects that activity to contacts, deals, and service tickets. That shared record helps larger teams see the full customer path, from first click to repeat order to support request.
The downside is cost and complexity. HubSpot pricing depends on contacts, hubs, and tiers, so a small store can pay for power it does not use. Setup also takes more time than a Shopify-native email tool. Choose HubSpot when the CRM matters as much as the campaign, not when you only need cart recovery.
- CRM, email, automation, and reporting in one system
- Strong team and pipeline tools
- Wide integration library
- Pricing is quote-based and rises with contacts and hubs
- Setup takes longer than a store-only email tool
- Overkill for a small single store
Yotpo helps stores turn buyers into repeat buyers and advocates. Its reviews product collects photo and video reviews and displays them on product pages, while loyalty and referrals reward repeat purchases. SMS and email add another channel to the same customer record. A free tier covers small order volumes, and paid reviews plans start at $15 per month, with loyalty plans from $199 per month on some tiers.
The catch is the total bill. Each module has its own pricing, and the cost grows with orders, so a store using reviews, loyalty, and SMS together should model the combined price. Yotpo fits best for direct-to-consumer brands that already have steady orders and want reviews and loyalty to drive the next order. Small stores may prefer a single-purpose review app until volume justifies the suite.
- Reviews, loyalty, referrals, and SMS under one login
- Strong Shopify presence
- Visual review widgets
- Costs rise with order volume and modules
- Advanced features sit on higher tiers
- Setup can feel broad for a small store
Attentive is built around text messaging for ecommerce brands. Its signup tools, including two-tap signup and popups, grow SMS lists fast, and its automation covers cart abandonment, win-back, and post-purchase messages. Personalization uses purchase and browsing data, and reporting ties messages to revenue, which helps larger brands justify SMS spend.
The barrier is price and fit. Attentive does not publish a standard entry price, and contracts are typically sized for mid-size and larger brands. Small stores will usually find Klaviyo or Omnisend cheaper for combined email and SMS. Attentive earns its place when SMS is a major revenue channel and the team can use its growth and personalization tools at scale.
- Strong SMS subscriber growth tools
- AI-driven personalization
- Deep Shopify integration and revenue reporting
- Custom pricing with no public entry price
- Best suited to mid-size and larger brands
- Email is secondary to SMS
Drip is an ecommerce email platform with a visual builder for multi-step workflows. It segments by purchase behavior, site activity, and engagement, and it includes unlimited sends on paid plans, which helps stores that email often. Pricing starts at $39 per month for up to 2,500 contacts, with a 14-day free trial.
The trade-off is the starting cost and channel mix. Drip has no free plan, so a brand-new store pays from the start, and its SMS offering is thinner than the SMS-first tools. It fits stores that send frequent email, use complex flows, and want predictable send costs as volume grows. Stores that need SMS as a primary channel should compare Klaviyo, Omnisend, or Attentive first.
- Unlimited email sends on paid plans
- Visual workflow builder
- Strong ecommerce segmentation
- No free plan
- Entry price is higher than Omnisend
- SMS support is thinner than Klaviyo or Attentive
Privy started with popups and signup forms, and it now covers email and SMS for Shopify stores. Its strength is list growth: targeted popups, spin-to-win style offers, and welcome flows turn site traffic into subscribers. Cart saver messages and post-purchase flows then help recover sales that would otherwise leave.
The limit is depth. Privy is excellent for capture and basic automation, but its segmentation and reporting do not match Klaviyo for complex ecommerce programs. Pricing also depends on the plan and volume, so check the current page for your store size. Privy fits Shopify stores that want fast list growth and simple automation in one tool.
- Fast popup and signup form setup
- Email and SMS in one Shopify-focused tool
- Cart saver and welcome flows
- Pricing varies by plan and volume
- Less deep than Klaviyo for segmentation
- Best value is tied to Shopify
How we picked these
We compared official pricing pages, store integrations, and automation features for tools that serve ecommerce stores directly. We favored tools with a clear ecommerce focus, a published free plan or trial, and automation for cart recovery, welcome, and post-purchase messages. We left out general social schedulers and ad platforms, since they solve a different part of marketing.
How to choose without overpaying
Start with your list size and message volume, then price the tool at that size, not at the entry tier. A tool that looks cheap at 500 contacts can cost three times as much at 10,000 contacts, and SMS adds a second bill on top of email. Model both channels before you commit, and check whether unsubscribed or inactive contacts count toward your bill.
Match the tool to the channel that pays
If email drives most repeat orders, pick a store-first email tool with deep segmentation. If SMS drives fast sales, pick a tool with strong signup, compliance, and revenue reporting for texts. If reviews and loyalty drive repeat orders, pick a suite that covers those jobs. One tool rarely leads on every channel, so rank your channels by revenue and buy for the top one.
Watch compliance and deliverability
Email and SMS both have consent and carrier rules, and a good tool makes compliance easier with double opt-in, clear unsubscribe handling, and signup records. Check that the tool supports your store platform, your SMS country rules, and your privacy policy. A cheap tool that harms deliverability or creates compliance risk costs more than it saves.
Test with a real flow before you migrate
Set up a welcome flow, a cart recovery flow, and one campaign, then check the reports for opens, clicks, orders, and revenue. Test signup on mobile, since most shoppers join from a phone. A two-week test with real traffic tells you more about fit than a demo, and it avoids a painful migration to the wrong platform.
FAQ
What are the best ecommerce marketing tools for a small store?
Omnisend and Mailchimp are strong small-store picks, with free plans and low entry pricing. Klaviyo also offers a free plan, but its paid tiers rise faster as contacts grow. Start with the tool that covers your main channel, then add a second tool only when a clear gap appears.
What is the best ecommerce marketing platform for email and SMS together?
Klaviyo and Omnisend both cover email and SMS in one login, with Klaviyo offering deeper segmentation and Omnisend offering lower entry pricing. Attentive is stronger for SMS alone, but it suits larger brands and custom pricing. Compare total email plus SMS cost at your list size before choosing.
How much do ecommerce marketing tools cost?
Costs vary by contacts, sends, and channels. Free plans cover up to 250 contacts on Klaviyo, Omnisend, and Mailchimp, while paid plans start at $13 to $20 per month for small lists. At 10,000 contacts, email alone can cost $100 to $150 per month, and SMS adds usage charges. Always check the vendor pricing page for your exact volume.
Do I need separate tools for reviews and loyalty?
Not always. Yotpo covers reviews, loyalty, referrals, and SMS in one suite, which suits brands that use all of those channels. Smaller stores can start with a single-purpose review app and add loyalty later. The suite saves logins, but it can cost more than separate tools at low volume.
What is the best marketing platform for ecommerce on Shopify?
Klaviyo, Omnisend, and Privy all integrate closely with Shopify, with Klaviyo offering the deepest data and Omnisend offering the lowest entry price. Privy leads for popups and fast list growth. Pick based on whether segmentation, price, or list growth matters most to your store.
How do I avoid paying for contacts I cannot email?
Archive or remove unsubscribed and inactive contacts where the tool allows it, and check whether the vendor bills for all contacts or only active profiles. Klaviyo bills by active profiles, while other tools bill by total contacts in the audience. Clean your list regularly, and set a schedule for removing hard bounces and long-term non-openers.
