If you are comparing the best email marketing tools for Squarespace, the real question is usually not which app sends a newsletter campaign. It is which tool fits the next thing your store needs to run, welcome emails, abandoned cart recovery, transactional updates, SMS, or a broader retention program that does not turn into a messy stack six months from now.
Squarespace email marketing can start simple. Growing stores often outgrow simple native campaigns fast. Once you need stronger automation workflows, better customer segmentation, or a clearer path from email marketing for Squarespace into SMS and transactional messaging, the differences between tools become much more practical.

At a glance
What is a Squarespace email marketing tool? It is a platform that connects to your store so you can run campaigns, automations, and customer messaging beyond basic native sends.
What are the best email marketing tools for Squarespace in 2026? Brevo, Mailchimp, Klaviyo, Omnisend, MailerLite, and ActiveCampaign stand out for different store stages and rollout priorities.
How do you choose one? Start with the first program you need live, newsletter, automation, transactional, or multichannel retention, then pick the platform that supports the next stage without forcing a rebuild.
Takeaway: The best tool depends less on the biggest feature list and more on what your Squarespace store needs to launch next.
Choose the best email marketing tool for Squarespace based on what you need to launch first
Squarespace email campaigns work well for basic store communication, but the best way to compare tools is to start with your first operational need. That usually decides whether a native campaign tool is enough or whether a connected platform will save time later.
Use this lens:
- Start with newsletters if your list is still small and the main goal is regular promotions, product drops, and content sends.
- Start with automation if you already have enough traffic and orders to justify welcome emails, browse follow-up, or abandoned cart recovery.
- Start with transactional messaging if reliable order updates, shipping notices, or account emails are part of the customer experience you want to control more closely.
- Start with multichannel retention if email alone is already too limiting and you want SMS, WhatsApp, chat, or CRM context in the same system.
This is where many Squarespace merchants get stuck. A newsletter-first tool can feel fine for three months, then force another migration once you need segmentation, lifecycle messaging, and tighter coordination across channels. A full retention platform can also be more than you need if your store is still validating demand and sending one campaign a week.
Here is a practical way to think about fit:
- Choose a lighter tool when speed matters most, your list is modest, and campaigns are still mostly manual.
- Choose an all-in-one platform when you know email marketing for Squarespace will expand into SMS marketing, transactional email, or customer lifecycle automation.
- Choose an ecommerce-first retention tool when flows and revenue attribution are already core buying criteria.
- Choose a CRM-led automation platform when your business has longer buying cycles, service touchpoints, or a wholesale motion next to ecommerce.
A connected platform becomes more attractive as soon as two things happen: your customer journeys get longer, and your channels start multiplying. That is usually the point where basic Squarespace email marketing turns into a broader retention stack.
Takeaway: Pick the tool that supports the first serious program you need live, then check whether it still fits the next two programs after that.
Match your email marketing tool for Squarespace to your next growth milestone
Different tools make sense at different stages. A store doing occasional campaigns has a different need from a brand trying to recover carts and drive repeat purchase with segmented flows.
| Growth Milestone | What Usually Changes | Best Tool Type | Strong Candidates | What To Prioritize |
|---|---|---|---|---|
| Launching first campaigns | Need a simple editor and basic list building | Newsletter-first tool | MailerLite, Mailchimp | Ease of use, templates, signup forms |
| Building first automations | Welcome flow and cart recovery become important | Ecommerce marketing platform | Brevo, Omnisend, Klaviyo | Automation setup, audience sync, product triggers |
| Adding transactional communication | Order and account emails need better reliability and control | All-in-one or transactional-capable platform | Brevo, ActiveCampaign | Deliverability, event triggers, central message oversight |
| Expanding into SMS | Email alone stops being enough for promotions and reminders | Multichannel platform | Brevo, Omnisend, Klaviyo | Consent management, channel coordination, reporting |
| Formalizing retention marketing | Segmentation and repeat purchase drive growth | Ecommerce retention platform | Brevo, Klaviyo, ActiveCampaign | Segments, workflows, customer data, reporting |
| Operating across teams | Marketing, support, and sales signals need one customer view | All-in-one platform with CRM | Brevo, ActiveCampaign | Shared customer records, CRM, channel breadth |
A small Squarespace store often moves through these milestones in order, but not always. Some brands need transactional reliability early. Others want SMS quickly because product drops or local promotions respond better to mobile-first communication.
Brevo often fits well when those milestones start to overlap. If your team wants campaigns, automation, transactional messaging, and customer context in one platform, the operational upside matters as much as the marketing features.
If you want to test that path before committing, Brevo includes a free plan and does not require a credit card to get started.
Takeaway: Your next growth milestone is a better buying filter than a generic feature checklist.
Our methodology at Brevo: how we tested
This article covers the best email marketing tools for Squarespace, including our own platform, Brevo. Our suggestions are based on our own research and testing. To learn exactly how we evaluate tools, check out our dedicated methodology article. The features listed here are a selection of what each email marketing tool for Squarespace offers. For exact pricing and a full, up-to-date feature list, check the providers' websites.
In practice, the review focuses on buyer-facing criteria that matter to a Squarespace store:
- Connection to Squarespace, including how naturally the tool fits store data and campaign setup.
- Newsletter usability, because many merchants still need campaign creation to stay simple.
- Automation depth, especially for welcome flows, cart recovery, and repeat purchase journeys.
- Transactional readiness, since ecommerce customer experience depends on more than promotional sends.
- Multichannel options, such as SMS, WhatsApp, chat, or CRM context for future growth.
- Pricing shape, with attention to how costs tend to move as your audience grows.
No single tool wins every category. Some are stronger for deep ecommerce retention, others for simplicity, and others for connected customer communication across more than one channel.
Takeaway: The goal is not to name one universal winner. It is to help you choose the right fit for a Squarespace store at your current stage.
The 6 best email marketing tools for Squarespace
Pick Brevo when your Squarespace store is ready for more than newsletters
Brevo fits Squarespace merchants who have moved past one-off campaigns and want a cleaner path into automation, transactional messaging, and multichannel retention. You can run email, SMS, WhatsApp, chat, and CRM-backed communication from one platform. That matters once customer messaging starts spreading across separate tools.
It is also a strong fit for teams that care about pricing predictability. Brevo’s model is shaped around emails sent, with generous contact storage, so your bill tracks activity more closely than audience-size-first models. For stores with growing lists but uneven campaign volume, that can be easier to plan around.
Brevo also brings a deliverability background that matters in ecommerce. Order confirmations, shipping updates, password resets, and lifecycle messages all affect trust, not only marketing performance. Bringing campaign and transactional communication closer together can reduce handoff friction.
One limit to know: if your retention team wants the most specialized ecommerce flow depth from day one, a more ecommerce-centric platform may offer more ready-made revenue workflows out of the box. For many Squarespace stores, Brevo is the best overall fit when you want approachable setup, multichannel reach, and room to grow without stitching together separate systems.
Verdict: Choose Brevo if your next step is not only better email, but connected customer messaging across email, SMS, automation, and transactional use cases.
Choose Mailchimp vs. Brevo if your main priority is familiar campaign building
Mailchimp remains a familiar choice for stores that want to get regular campaigns out the door without a long setup period. The template builder is approachable, the interface is familiar to many marketers, and it works well for teams still centered on newsletters and seasonal sends.
That makes it a reasonable option when your store is early, your automation needs are still basic, and your team values ease over operational breadth. It can also suit businesses where the ecommerce side is only one part of the brand’s marketing mix.
The tradeoff is cost shape and long-term stack design. As your audience grows, pricing can become a bigger planning issue, and businesses often add other tools to cover deeper automation or transactional needs. Mailchimp’s official pricing plans also show how limits and overages can become part of that calculation.
The fit here is straightforward: Mailchimp works best when your Squarespace email marketing plan is still campaign-led and you want a tool that many teams already know how to use.
Takeaway: Pick Mailchimp for familiar newsletter execution, not because it is the easiest long-term answer for a growing retention stack.
Choose Klaviyo vs. Brevo if retention automation is already the core goal
Klaviyo is the strongest pick in this list for stores that already know advanced retention marketing is the priority. If you are evaluating tools through segmentation, revenue attribution, lifecycle flows, and repeat purchase performance, it is one of the clearest answers.
That makes Klaviyo especially appealing for brands with enough traffic and orders to support meaningful automation, and for teams that have someone actively managing retention. Its appeal grows when automated journeys matter more than newsletter simplicity.
The tradeoff is complexity and budget pressure for smaller stores. If your immediate need is still broad campaign management with a smoother route into multichannel communication, another platform may feel easier to live with. Klaviyo’s pricing model is also worth weighing early.
Verdict: Klaviyo is the clear recommendation for a fast-growing store where retention automation already outranks simplicity as the buying criterion.
Takeaway: Go with Klaviyo when advanced ecommerce lifecycle marketing is the center of the decision.
Choose Omnisend vs. Brevo if you want ecommerce-focused email and SMS without extra sprawl
Omnisend sits in a useful middle ground for merchants who want more than a newsletter tool but do not necessarily need a wider CRM platform. It is built around ecommerce marketing, and that shows in the way email and SMS work together for promotions, automations, and revenue-driving campaigns.
For a Squarespace store, that can make Omnisend an appealing option when the next move is adding SMS to established email flows. It is also a sensible fit for teams that want ecommerce-oriented workflow logic without moving into a broader platform category.
Its main tradeoff is platform breadth. If you expect to bring transactional messaging, chat, WhatsApp, or deeper CRM use cases into the same system, you may outgrow the narrower scope. Omnisend’s official pricing plans are another practical checkpoint.
The call here depends on channel mix. Omnisend is a strong choice when your roadmap centers on ecommerce email and SMS, and a less obvious one when you want a wider customer communication stack.
Takeaway: Omnisend fits stores that want focused ecommerce messaging, especially email plus SMS, without stepping into a bigger all-in-one setup.
Choose MailerLite if you need a simple, budget-conscious start
MailerLite is the tool in this list that best suits founder-led stores looking for clarity and low setup effort. The editor is clean, the workflow builder is approachable, and it is often enough for brands moving from occasional sends into a more regular campaign rhythm.
That matters if your store is still learning what resonates with subscribers. You may not need deep segmentation or broad channel coverage yet. You may need a tool that makes consistent sending easier to maintain.
MailerLite becomes less appealing later in retention. As your Squarespace email marketing integration needs grow into SMS, transactional messaging, or richer customer data use cases, the platform can start to feel more limited.
Verdict: MailerLite is the clear recommendation for a small store that needs simplicity first and can revisit stack depth later.
Takeaway: Choose MailerLite when your priority is an easy start, not a multichannel destination.
Choose ActiveCampaign vs. Brevo if your customer journeys are more complex than a typical store
ActiveCampaign is the strongest fit here for businesses whose customer communication does not look like a simple direct-to-consumer flow. If your Squarespace store also supports consultations, high-consideration purchases, repeat service touchpoints, or a wholesale pathway, the automation and CRM mix can be attractive.
This tool makes more sense when lifecycle complexity is part of the model. You might need branching journeys, sales follow-up logic, or more structured CRM workflows alongside email marketing. In that environment, ActiveCampaign can be a better fit than a lighter ecommerce tool.
The tradeoff is operational overhead. Smaller stores can end up paying for flexibility they do not use, and the system may feel heavier than necessary when your needs are still mostly campaign and cart based. ActiveCampaign’s platform pricing is part of that tradeoff.
The call here is narrower than with some others on this list. ActiveCampaign is a strong recommendation for mixed ecommerce and CRM use cases, not the default pick for a straightforward Squarespace retail store.
Takeaway: ActiveCampaign works best when your store sits inside a more complex customer lifecycle, not when you only need faster promotional sends.
Use a simple decision framework to choose between newsletter tools and all-in-one platforms
A large share of buying confusion comes from comparing tools in the wrong category. Some platforms are built to help you send campaigns efficiently. Others are meant to become the system behind a wider customer communication program.
Use this decision framework:
| If Your Main Bottleneck Is... | You Probably Need... | Best-Fit Tools |
|---|---|---|
| Campaigns take too long to build | A newsletter-first tool | Mailchimp, MailerLite |
| You need welcome and cart workflows live fast | An ecommerce marketing platform | Brevo, Omnisend, Klaviyo |
| Customer messages are split across tools | An all-in-one platform | Brevo |
| Your retention team wants deeper segmentation and revenue flows | A retention-focused ecommerce platform | Klaviyo |
| Your business has sales or service steps beyond checkout | A CRM-led automation platform | ActiveCampaign |
| You want to add SMS without rebuilding everything | A multichannel ecommerce tool | Brevo, Omnisend |
Two rules keep this simple:
- Do not overbuy for a problem you do not have yet.
- Do not underbuy if you already know your next channel or workflow is coming soon.
The first rule protects early-stage stores from heavy setup. The second rule protects growing stores from switching twice.
Takeaway: Decide whether you are solving for campaign speed, retention depth, or channel consolidation, then choose within that category.
Plan for the real cost of switching from Squarespace email campaigns to a connected tool
The visible subscription cost is only one piece of the move from native Squarespace email campaigns to a connected platform. The real cost sits across setup time, data cleanup, workflow rebuilds, and the shape of future billing as your audience grows.
Look at five cost layers:
1. Migration effort
Exporting lists is the easy part. Rebuilding segments, templates, signup forms, and automations is what takes time.
2. Data quality work
If your contacts are poorly tagged or spread across inconsistent forms, your first automation build will slow down.
3. Operational overlap
For a short period, your team may run campaigns in one place while moving transactional or automated messaging into another.
4. Channel expansion
If SMS or WhatsApp is on the roadmap, a platform that already supports those channels can reduce future switching cost.
5. Pricing behavior over time
Some tools become more expensive mainly as the number of stored profiles rises. Others track more closely with sends or usage patterns. That distinction matters for stores with seasonal volume or rapidly growing lists.
This is why pricing shape matters more than a headline starting tier. If your list is scaling faster than your send volume, contact-based billing can feel very different from send-based billing over time. If your program is getting more advanced across email, SMS, and transactional communication, the cost of multiple tools also adds up.
Squarespace email marketing integration decisions should account for where your store will be in the next year, not only the next month.
Takeaway: The cheapest starting point is not always the lowest-cost operational choice once migration, channels, and future billing patterns are included.
Roll out email, SMS, and transactional messaging for your Squarespace store step by step
The safest rollout is staged. You do not need every channel live on day one, but you do want a plan that prevents another switch as your store grows.
Use this rollout sequence:
1. Launch core campaigns first
Start with newsletter templates, list segmentation, and signup capture so regular sends move into the new platform quickly.
2. Build your essential automations
Add a welcome series, abandoned cart flow, and a post-purchase sequence before expanding into edge cases.
3. Connect transactional messaging
Bring order confirmations, shipping updates, or account emails into a setup with strong delivery and clear oversight.
4. Add SMS selectively
Use SMS for high-intent reminders, launches, or time-sensitive promotions, not as a copy of every email.
5. Refine segmentation and reporting
Once the basics are live, improve performance with better audience logic, product interest signals, and lifecycle views.
6. Expand into multichannel retention
If your store benefits from chat, WhatsApp, CRM follow-up, or loyalty touchpoints, layer them in after the core journeys are stable.
For many Squarespace merchants, that path points toward an all-in-one platform because each phase builds on the previous one. You avoid separate migrations for campaigns, automation, SMS, and transactional messaging later.
Takeaway: Roll out in stages, but choose a platform that can carry the full path from first campaign to connected retention.
