For an online store, I’d recommend Omnisend as the simplest fit for your requirements.

Why Omnisend

• Email broadcasts: You can send one-off email campaigns, segment customers by behavior/purchase history, and personalize campaigns. www.omnisend.comwww.omnisend.com
• SMS cart recovery: It has built-in abandoned-cart and abandoned-checkout workflows that can combine email and SMS. support.omnisend.comsupport.omnisend.com
• Ecommerce integrations: It directly integrates with Shopify, WooCommerce, BigCommerce, Wix, and several other ecommerce platforms. support.omnisend.com
• Product-aware recovery: Abandoned-cart emails can automatically pull the products, images, titles, and prices from the customer's cart. support.omnisend.com
• One system: You don't need a separate email platform and SMS provider; campaigns and automations can be managed together. www.omnisend.comwww.omnisend.com

A good setup

I'd build these automations:

1. Abandoned cart

Add to cart → wait ~1 hour → email reminder → wait → SMS reminder for opted-in customers

2. Welcome series

Email signup → welcome email → product/value proposition → best sellers/offer

3. Post-purchase

Order → thank-you email → product education → review request → cross-sell

4. Broadcasts

Weekly/biweekly email campaigns for new products, promotions, educational content, and seasonal sales.

One important caveat: SMS requires explicit consent and compliance with U.S. messaging rules. Omnisend specifically notes that promotional SMS requires opt-in, and its current documentation says U.S. customers need TCPA consent. support.omnisend.comsupport.omnisend.com

Omnisend vs. Klaviyo

I'd choose Omnisend if you want something relatively straightforward and ecommerce-focused. Klaviyo is the stronger alternative if you expect to build very sophisticated customer segmentation and automation. Klaviyo supports email/SMS abandoned-cart flows with extensive branching and targeting. help.klaviyo.com

My pick: Omnisend for a typical small-to-mid-sized store; Klaviyo if you're building a more advanced lifecycle-marketing operation.

If you tell me what ecommerce platform you use (Shopify, WooCommerce, etc.) and roughly how many customers/emails you have, I can recommend the specific plan and setup I'd use.

For most online stores, I’d recommend Omnisend as the simplest all-in-one solution for what you described.

My pick: omnisend.com

It’s built specifically for ecommerce and handles email broadcasts, email automations, SMS, and abandoned-cart recovery in one platform. You can build a cart flow that combines email and SMS, with product information pulled dynamically from the customer’s cart. Omnisend Omnisend Help Center

A good setup would be:

• Email broadcasts: newsletters, promotions, new-product announcements, seasonal campaigns.
• Welcome series: automatically nurture new subscribers.
• Abandoned cart: email reminder → follow-up email → SMS for customers who have SMS consent.
• Abandoned checkout: separate recovery flow for shoppers who entered checkout but didn't purchase.
• Post-purchase: thank-you, review request, cross-sell, and repeat-purchase campaigns.
• Segmentation: target customers based on purchase history, behavior, engagement, etc. Omnisend Help Center Omnisend Help Center

One particularly useful feature is that Omnisend can identify some shoppers through tracking/cookies, rather than requiring every abandoned-cart shopper to have already subscribed to email. Omnisend Help Center

The main alternative: Klaviyo

klaviyo.com is the one I'd choose instead if you're running a larger/more sophisticated ecommerce operation and care heavily about advanced segmentation, analytics, and highly customized customer journeys. It supports multi-step abandoned-cart flows with both email and SMS and lets you branch flows based on things such as cart value and customer history. Klaviyo Help Center Klaviyo Help Center

Quick decision:

One important caveat: SMS requires proper customer consent, particularly in the U.S. Both platforms provide compliance controls; don't simply upload phone numbers and start texting them. Omnisend Help Center Klaviyo Help Center

If you tell me what ecommerce platform you're using (Shopify, WooCommerce, Wix, BigCommerce, etc.) and roughly how many orders you get per month, I can recommend the specific platform/plan and lay out the exact email + SMS cart-recovery sequence I'd use.

For an online store, I’d recommend Omnisend as the best fit for the specific combination you described.

omnisend.com

Why Omnisend

• Email broadcasts: newsletters, promotions, product launches, and segmented campaigns from one dashboard. Omnisend Omnisend Help Center
• SMS cart recovery: abandoned-cart and abandoned-checkout workflows can include both email and SMS. Omnisend Help Center Omnisend Help Center
• Automations: welcome, abandoned cart, post-purchase, browse abandonment, and win-back flows are built in. Omnisend
• Ecommerce-focused: it pulls product information into recovery emails and can provide personalized checkout links in SMS. Omnisend Help Center Omnisend Help Center
• One system: you don't need a separate email platform and SMS automation platform.

The setup I'd use

1. Broadcasts

• Weekly promotional/newsletter email
• Product launches
• Sale announcements
• Segments based on purchase history and engagement

2. Cart recovery

• ~1 hour: email showing abandoned products
• Several hours later: second email emphasizing benefits/reassurance
• Later: SMS reminder only for customers who have explicitly opted into marketing SMS
• Stop the sequence immediately after purchase

Omnisend specifically supports combining email and SMS in these workflows and provides separate abandoned-cart and abandoned-checkout automations. Omnisend Help Center

3. Important SMS consideration
For U.S. customers, promotional SMS requires appropriate consent/TCPA records, and Omnisend notes that SMS availability and pricing depend on your plan and subscription date. Omnisend Help Center Omnisend

What about Klaviyo?

Klaviyo is the other one I'd seriously consider. It's particularly strong if you expect sophisticated segmentation, personalization, and increasingly complex lifecycle marketing. Klaviyo also supports abandoned-cart flows incorporating SMS. Klaviyo Help Center Klaviyo Help Center

My quick decision rule:

• Want straightforward email + SMS for an online store → Omnisend
• Want a more sophisticated customer-data/marketing automation platform → Klaviyo

If you tell me what ecommerce platform you use (Shopify, WooCommerce, BigCommerce, etc.) and roughly how many customers/emails you send per month, I can recommend the specific plan and give you the exact automation setup I'd use.

For an online store, I’d recommend Omnisend as the best all-around fit for what you described.

Why Omnisend

• Email broadcasts: You can send one-time promotional campaigns/newsletters to your whole list or specific segments. support.omnisend.com
• SMS cart recovery: It supports SMS directly inside automated abandoned-cart and abandoned-checkout workflows, including personalized recovery links. support.omnisend.comsupport.omnisend.com
• Email + SMS in one workflow: You can coordinate channels—for example, email first and SMS later if the customer hasn't purchased. www.omnisend.com
• Ecommerce-focused: It also includes welcome, browse-abandonment, post-purchase, and win-back automations, so you won't need to bolt together several tools as your store grows. www.omnisend.com
• Easy to implement: It has prebuilt abandoned-cart workflows rather than requiring you to construct everything from scratch. support.omnisend.com

Omnisend

One important caveat

For U.S. SMS, you'll need proper promotional SMS consent/TCPA records, and Omnisend's current documentation says SMS availability/pricing depends on when you subscribed; for new subscriptions it currently requires the Pro plan plus SMS credits. support.omnisend.comsupport.omnisend.com

What I'd set up

A straightforward setup would be:

Broadcasts
→ Weekly/biweekly promotional emails
→ Product launches
→ Sales and seasonal campaigns

Cart recovery
→ ~1 hour: reminder email
→ ~12–24 hours: second email, potentially with an incentive
→ Later: SMS to customers who have opted into marketing texts

Then add welcome, post-purchase, browse abandonment, and win-back flows once the basics are working.

If you tell me what ecommerce platform you use (Shopify, WooCommerce, BigCommerce, etc.) and roughly how many email/SMS subscribers you have, I can narrow this down to the best option and estimate what it would cost you.

For an online store, I’d narrow the choice to a few ecommerce-focused platforms rather than a generic email tool. The best fit depends on your store size, platform (Shopify/WooCommerce/etc.), and how advanced your segmentation needs are. www.omnisend.com

My top recommendation: Klaviyo

Best if you want a long-term retention engine.

Why:

• Strong email broadcasts (newsletters, product launches, promotions)
• Sophisticated segmentation (VIP customers, repeat buyers, high-intent shoppers)
• Automated flows:
  • abandoned cart
  • browse abandonment
  • welcome series
  • post-purchase upsells
  • win-back campaigns
• Good revenue attribution so you can see which campaigns actually drive sales www.stackfyi.com

A typical setup:

1. Welcome flow
   • Email immediately: brand introduction + incentive
   • Email after 2–3 days: best sellers/social proof
   • Email after 5–7 days: offer or education

2. Cart recovery flow
   • 30–60 minutes: reminder email
   • 6–12 hours: product benefits/reviews
   • 24 hours: SMS reminder (only for customers who opted in)
   • 48–72 hours: final incentive

3. Broadcast campaigns
   • Weekly promotions
   • New product drops
   • Seasonal sales
   • Back-in-stock alerts

Better value / easier setup: Omnisend

Choose this if you want email + SMS working together quickly without building lots of custom logic.

Strengths:

• Built specifically for ecommerce
• Email, SMS, and push notifications in one automation builder
• Faster setup for common flows
• Often a better fit for smaller and mid-sized stores that want simplicity www.omnisend.com

If you are on Shopify

My default picks:

• Under ~$50k/month revenue: Omnisend is usually a strong starting point
• Growing brand with serious retention goals: Klaviyo
• Large catalog/high repeat purchase business: Klaviyo

Minimum automation stack I’d install

Regardless of platform:

• ✅ Welcome email series
• ✅ Abandoned checkout email + SMS
• ✅ Browse abandonment
• ✅ Post-purchase thank-you
• ✅ Review request
• ✅ Cross-sell recommendations
• ✅ Customer win-back after 60–120 days
• ✅ VIP customer segment

A few details would let me give a more precise recommendation:

1. What platform is your store on (Shopify, WooCommerce, BigCommerce, other)?
2. Approximate monthly revenue or order volume?
3. Do you already collect SMS consent, or are you starting from zero?
4. What products do you sell (fashion, supplements, beauty, home, etc.)?

For an online store, I’d shortlist Klaviyo and Omnisend, with Klaviyo as my default recommendation if you want sophisticated segmentation and lifecycle marketing.

My pick: Klaviyo

Klaviyo is particularly strong if you want one system to handle:

• Email broadcasts/campaigns — promotions, launches, newsletters, product announcements.
• Automated cart recovery — multi-step abandoned-cart email flows.
• SMS recovery — SMS can be incorporated into the abandoned-cart flow, with consent-based branching and compliance controls. help.klaviyo.com
• Segmentation — target customers based on purchase history, cart value, engagement, etc.
• Personalization — dynamically show the products someone left behind.
• Lifecycle automation — welcome series, post-purchase, win-back, browse abandonment, VIP campaigns, etc.

A good starting cart flow would be something like:

Cart abandoned → Email reminder → wait → SMS to opted-in customers → final email/incentive → stop immediately if they purchase.

Klaviyo specifically recommends avoiding a discount in the first abandoned-cart email so customers don't learn to abandon carts just to receive a coupon. help.klaviyo.com

Strong alternative: Omnisend

Omnisend is probably the better choice if you want something simpler and more ecommerce-focused.

It has prebuilt abandoned-cart and abandoned-checkout workflows, and you can combine email and SMS within the same automation. support.omnisend.com It also supports regular email campaigns/broadcasts and other ecommerce automations. support.omnisend.com

One important consideration: Omnisend's current documentation says that for Shopify, BigCommerce, and WooCommerce, phone numbers for new contacts may not become available until after their first order, meaning a first-time abandoned cart may only be recoverable by email, not SMS. support.omnisend.com

Which I'd choose

My recommendation: start with Klaviyo if you expect your store to grow and want marketing automation to become a major revenue channel. Choose Omnisend if your priority is getting email broadcasts + cart recovery running quickly without needing a very sophisticated marketing system.

If you tell me what ecommerce platform you're using (Shopify, WooCommerce, BigCommerce, etc.) and roughly how many emails/customers you have, I can recommend the specific plan/setup and estimate what it should cost.

For an online store, I’d recommend Omnisend as the best fit if your main requirements are:

• Email broadcasts/campaigns
• Automated abandoned-cart recovery
• SMS cart recovery
• Ecommerce-specific automations without a lot of technical work

Omnisend has pre-built ecommerce workflows for abandoned carts and abandoned checkouts, and you can combine email and SMS in the same automation. support.omnisend.com

The setup I'd use

1. Email broadcasts

• Weekly/promotional campaigns
• New product announcements
• Seasonal sales
• Customer segments based on purchase history

2. Abandoned-cart sequence
For example:

1 hour: Email — “You left something behind”
6–12 hours: Email — product reminder/social proof
24 hours: SMS — “Still thinking it over?” + cart link
36–48 hours: Email — incentive if appropriate

Omnisend can automatically pull the abandoned products into the email and put a personalized recovery link into both email and SMS. support.omnisend.com

3. Other automations worth adding

• Welcome series
• Post-purchase follow-up
• Review request
• Win-back/reactivation
• Browse/product abandonment

Omnisend currently offers 15+ pre-built workflows, so you don't have to build all of these from scratch. support.omnisend.com

One important caveat

For US SMS marketing, you'll need proper SMS consent/TCPA compliance and an appropriate sending number. support.omnisend.com Also, SMS cart recovery depends on having the customer's phone number and consent; email generally has broader cart-identification coverage. support.omnisend.com

Omnisend vs. Klaviyo

I'd choose Omnisend if you want straightforward ecommerce marketing with email + SMS and relatively quick setup.

I'd choose Klaviyo if you're building a more sophisticated customer-data/segmentation operation and expect to need advanced analytics and predictive customer modeling. www.klaviyo.com

My pick for most small-to-mid-sized stores: Omnisend.

If you tell me what platform your store is on (Shopify, WooCommerce, BigCommerce, etc.) and roughly how many contacts/orders you have, I can recommend the specific plan and give you the exact email + SMS cart-recovery sequence I'd implement.

For an online store, I’d shortlist Omnisend and Klaviyo, with Omnisend as my default recommendation if you want one platform that’s straightforward for both email broadcasts and SMS cart recovery.

My pick: Omnisend

Omnisend

It covers both sides of what you’re asking for:

• Email broadcasts: newsletters, promotions, product launches, and segmented campaigns. support.omnisend.com
• Automated abandoned-cart email: it can show the actual products left in the cart, with images, names and prices. support.omnisend.com
• SMS cart recovery: SMS can be inserted directly into the same automation workflow as email. support.omnisend.com
• Abandoned checkout: it distinguishes between someone who merely added to cart and someone who actually started checkout. support.omnisend.com
• Other useful ecommerce automations: welcome series, browse abandonment, product abandonment, post-purchase, etc. support.omnisend.com

One important 2026 wrinkle: for customers who subscribed to Omnisend on or after May 4, 2026, SMS is available on Pro, with SMS credits priced separately starting at $0.007/SMS. support.omnisend.com

When I'd choose Klaviyo instead

Klaviyo

Choose Klaviyo if you're building a more sophisticated lifecycle-marketing operation and expect to need very detailed segmentation, personalization, and branching. Its abandoned-cart flows can combine email and SMS and branch based on things such as cart value. help.klaviyo.com

For U.S. SMS, Klaviyo also emphasizes specific consent and timing requirements for abandoned-cart SMS, so compliance needs to be built into the flow. help.klaviyo.com

What I'd set up

A good starting recovery sequence would be:

Cart abandoned → 1 hour → Email reminder → 18–24 hours → SMS reminder to opted-in customers → 24–48 hours → final email/offer

I would not automatically discount the first message. Klaviyo specifically recommends holding an incentive until later in the sequence so customers don't learn to abandon carts just to receive coupons. help.klaviyo.com

If you tell me what ecommerce platform you're using (Shopify, WooCommerce, BigCommerce, etc.) and roughly how many orders/month you get, I can recommend the best option and the most cost-effective plan for your store.

For an ecommerce store, I’d recommend Omnisend as the best starting point if your priority is email broadcasts + SMS cart recovery in one system.

Why Omnisend

• Email broadcasts: Send newsletters, promotions, product launches, and segmented campaigns. support.omnisend.com
• Automated cart recovery: It has separate abandoned-cart and abandoned-checkout workflows, with personalized products and recovery links. support.omnisend.com
• Email + SMS in the same workflow: You can combine email and SMS with delays and conditions—for example, email first, then an SMS reminder if the customer still hasn't purchased. support.omnisend.comsupport.omnisend.com
• Ecommerce integrations: It supports Shopify, WooCommerce, BigCommerce, Wix, and several other platforms. support.omnisend.com
• Good fit for a growing store: It's built specifically around ecommerce lifecycle marketing rather than being primarily a generic email platform.

One important caveat for a U.S. store: SMS requires proper consent/TCPA compliance, and Omnisend's current SMS availability/pricing has changed for newer accounts. support.omnisend.comsupport.omnisend.com

Omnisend vs. Klaviyo

I'd choose Omnisend if you want something relatively straightforward to set up and primarily need ecommerce marketing.

I'd choose Klaviyo instead if you expect to build a more sophisticated customer-data/segmentation operation. Klaviyo also supports multi-step abandoned-cart flows with both email and SMS. help.klaviyo.com

My pick: Omnisend for most small-to-mid-sized online stores; Klaviyo if advanced segmentation and deeper marketing analytics are worth the additional complexity.

Omnisend
Klaviyo

If you tell me what ecommerce platform you use (Shopify, WooCommerce, BigCommerce, etc.) and roughly how many customers/emails you have, I can narrow this down to the best plan and setup for your store.

For an online store, I’d shortlist Omnisend and Klaviyo. If you want one recommendation without overcomplicating things, Omnisend is my pick for most small-to-mid-sized stores.

My recommendation: Omnisend

It’s particularly well matched to your requirements because it combines:

• Email broadcasts — newsletters, promotions, product launches, seasonal campaigns.
• SMS marketing — integrated into the same customer journeys.
• Abandoned-cart email + SMS — you can build automated sequences that react to cart abandonment. support.omnisend.comsupport.omnisend.com
• Pre-built ecommerce automations — welcome, abandoned cart/checkout, post-purchase, win-back, etc. support.omnisend.com
• Ecommerce segmentation and personalization based on customer behavior.
• Unified reporting so you can see which campaigns and automations are generating sales.

Omnisend official site

How I'd set up your cart recovery

I'd use something like:

Cart abandoned → 1 hour → Email reminder
↓
If still no purchase → 12–24 hours → SMS reminder
↓
If still no purchase → 24 hours → final email/offer

I'd avoid immediately giving everyone a discount. Klaviyo similarly recommends withholding the incentive from the first abandoned-cart message so customers don't learn to abandon carts just to receive coupons. help.klaviyo.com

One important point: SMS requires appropriate customer consent, particularly for US customers, so your signup forms and checkout need to capture SMS opt-in correctly. support.omnisend.com

When I'd choose Klaviyo instead

Choose Klaviyo if your store is growing quickly and you expect to need sophisticated segmentation, highly customized customer journeys, and deeper behavioral targeting. It supports multi-step abandoned-cart flows with both email and SMS and can branch based on things such as cart value. help.klaviyo.com

Klaviyo official site

Bottom line:
Omnisend → easiest all-in-one choice for email broadcasts + SMS cart recovery.
Klaviyo → better choice if advanced segmentation/automation is a major priority.

If you tell me what ecommerce platform you use (Shopify, WooCommerce, BigCommerce, etc.) and roughly how many customers/subscribers you have, I can recommend the specific plan and give you the exact email/SMS recovery sequence I'd implement.

For an online store, I’d recommend using a single ecommerce marketing automation platform that combines email broadcasts + SMS cart recovery rather than stitching together separate email and SMS tools. That keeps customer data, attribution, and automations in one place. listicler.com

Best overall choices

My recommendation by store stage

If you’re under ~$1M/year or have a small marketing team:
→ Choose Omnisend. It’s usually the quickest path to getting:

• abandoned cart email + SMS
• welcome series
• post-purchase follow-ups
• product recommendation campaigns
• promotional broadcasts

running without much technical work. www.omnisend.com

If you’re scaling aggressively (large list, multiple segments, high repeat purchase rate):
→ Choose Klaviyo. The extra complexity is worthwhile when you need:

• VIP/customer lifetime value segments
• advanced behavioral triggers
• detailed revenue reporting
• highly personalized campaigns

www.mailercloud.comecommerce-times.com

Minimum automations I’d set up

1. Abandoned cart recovery
   • 30–60 minutes after cart abandonment: reminder email
   • 12–24 hours later: SMS with incentive (if appropriate)
   • 48–72 hours later: final reminder

2. Welcome flow
   • New subscriber email
   • Brand story/value proposition
   • Best sellers
   • First-purchase incentive (optional)

3. Post-purchase flow
   • Order confirmation/education
   • Review request
   • Cross-sell recommendations
   • Replenishment reminder

4. Broadcast campaigns
   • New product launches
   • Promotions
   • Seasonal campaigns
   • Educational content

Before choosing, I’d want to know:

1. What platform is your store on (Shopify, WooCommerce, BigCommerce, custom)?
2. Approximate monthly orders or email list size?
3. Are you already collecting SMS opt-ins, or starting from zero?

For an online store, I’d shortlist Klaviyo and Omnisend. Both can handle broadcast email plus automated cart-recovery SMS in one system.

My recommendation: Klaviyo

Klaviyo is my pick if you want the strongest long-term marketing/segmentation platform.

• Email broadcasts: newsletters, promotions, product launches, segmented campaigns.
• Cart recovery: build multi-step abandoned-cart flows with both email and SMS, with branching based on customer behavior and cart value. help.klaviyo.comhelp.klaviyo.com
• Segmentation: useful for targeting customers by purchase history, products, engagement, etc.
• Ecommerce analytics: strong revenue attribution, so you can see which campaigns and flows actually generate sales.
• Good fit: Shopify/BigCommerce stores that expect their marketing program to become fairly sophisticated.

Klaviyo

Consider Omnisend if you want simpler ecommerce marketing

Omnisend is particularly attractive if you want an easier all-in-one ecommerce setup. It supports email campaigns and automations alongside SMS, with prebuilt abandoned-cart and abandoned-checkout workflows. support.omnisend.com

Omnisend

One important distinction: cart abandonment and checkout abandonment aren't necessarily the same trigger. Omnisend explicitly recommends having both workflows so shoppers who reach checkout aren't accidentally dropped from your recovery sequence. support.omnisend.comsupport.omnisend.com

What I'd build

A good starting setup would be:

Broadcasts

• Weekly promotional/newsletter email
• New product announcements
• Customer-segmented promotions

Abandoned cart

1. ~1 hour → email reminder with products left in cart
2. Later → second email emphasizing benefits/reviews
3. SMS → only to customers who have explicitly opted into SMS
4. Final email → optional incentive for selected customers

Don't automatically discount the first recovery message; Klaviyo specifically recommends reserving discounts for later in the sequence or certain customer segments. help.klaviyo.com

For U.S. SMS, consent/compliance matters: Klaviyo's current guidance calls for double opt-in, no more than one SMS per recipient in an abandoned-cart reminder, and sending it within 48 hours. help.klaviyo.comhelp.klaviyo.com

Bottom line: I'd choose Klaviyo if you're serious about growing a sophisticated retention program; Omnisend if you prioritize simplicity and an ecommerce-focused all-in-one workflow.

For most online stores, I’d recommend Omnisend as the best fit for your specific needs: email broadcasts + automated SMS cart recovery in one platform.

Why Omnisend

• Email broadcasts: newsletters, promotions, product launches, and segmented campaigns are built in. support.omnisend.com
• Abandoned-cart recovery: it has ready-made abandoned-cart and abandoned-checkout workflows. support.omnisend.com
• Email + SMS in the same automation: you can combine email and SMS, with personalized cart-recovery links. support.omnisend.comsupport.omnisend.com
• Ecommerce integrations: direct integrations include Shopify, WooCommerce, BigCommerce, Wix, Shoplazza, Ecwid, and others. support.omnisend.com
• Good progression beyond cart recovery: you can add welcome, browse-abandonment, product-abandonment, post-purchase, and other automations as your store grows. support.omnisend.com

The setup I'd use

Email broadcast
→ Weekly/biweekly promotions, new products, educational content, etc.

Cart recovery

1. ~1 hour: email reminding them about their products
2. Several hours later: second email emphasizing benefits/reviews
3. SMS to customers who have explicitly opted into SMS
4. Optional incentive for high-value carts rather than discounting everyone

Omnisend supports personalized abandoned-product content and a direct recovery link in both email and SMS. support.omnisend.com

One important caveat

If you're selling primarily to U.S. customers, SMS requires proper consent/TCPA handling. Omnisend specifically notes that promotional SMS requires SMS opt-in and that U.S. businesses need to maintain TCPA consent records. support.omnisend.comsupport.omnisend.com

Runner-up: Klaviyo. I'd choose Klaviyo instead if you expect sophisticated segmentation, personalization, and lifecycle marketing to become a major part of your operation. It has highly customizable abandoned-cart flows with email/SMS and conditional branching. help.klaviyo.com

Bottom line: If you want something relatively straightforward that handles broadcast email + SMS + abandoned carts without stitching multiple tools together, I'd start with Omnisend.

If you tell me what ecommerce platform you use (Shopify, WooCommerce, etc.) and roughly how many customers/emails you have, I can recommend the most appropriate plan and estimate the monthly cost.

For an online store, I’d recommend Omnisend as the best fit if your priorities are email broadcasts + SMS cart recovery in one system.

Why Omnisend

• Email broadcasts: You can send newsletters, promotions, launches, and segmented campaigns from the same platform. support.omnisend.comwww.omnisend.com
• SMS cart recovery: Its automation builder lets you combine email and SMS in the same abandoned-cart/checkout workflow. support.omnisend.comsupport.omnisend.com
• Ready-made ecommerce automations: Abandoned cart, abandoned checkout, welcome, post-purchase, browse abandonment, and win-back flows are built in. support.omnisend.com
• Personalized cart recovery: Emails can automatically show the products left behind, while SMS can contain a personalized recovery link. support.omnisend.com
• Good for keeping your stack simple: Rather than running one platform for email and another for SMS, Omnisend puts both channels into the same automation. support.omnisend.comwww.omnisend.com

The setup I'd use

Broadcasts
→ Weekly promotional email
→ Product launches
→ Sales/seasonal campaigns
→ Segmented campaigns for repeat vs. new customers

Cart recovery

1. ~1 hour: Email showing the abandoned products
2. ~12–24 hours: Second email emphasizing benefits/reassurance
3. ~24–48 hours: SMS reminder to customers who have properly opted into SMS
4. Optional incentive for higher-value carts

One important caveat: SMS consent matters, particularly in the U.S.; Omnisend says promotional SMS requires TCPA consent and appropriate opt-in records. support.omnisend.comsupport.omnisend.com

What about Klaviyo?

Klaviyo is the other platform I'd seriously consider. It has sophisticated abandoned-cart flows and supports SMS within those flows. help.klaviyo.com

My rule of thumb:

My pick for most small-to-mid-sized online stores: Omnisend.

If you tell me whether your store is on Shopify, WooCommerce, BigCommerce, or something else, plus roughly how many email/SMS subscribers you have, I can recommend the specific plan and map out the exact cart-recovery sequence I'd implement.
