Email software for Shopify stores, matched to catalog and order volume.

Klaviyo is the default for Shopify stores that want the store's own data to drive email. Its Shopify connector brings in orders, checkouts, products and customer events, and it comes with prebuilt flows for abandoned checkout, browse abandonment, welcome, post-purchase and winback. A store can launch those flows quickly and then edit the copy and product blocks to match its own catalog.

The weak point is cost at scale. The email plan is $100 a month at 5,000 profiles, $150 at 10,000 and $400 at 25,000. SMS is a separate plan, so a store that adds text messages should price both sides before committing. Its subscription-billing logic is also thinner than what dedicated subscription tools offer, which matters for stores selling replenishment products.

Choose Klaviyo if you want the fastest route to working cart and post-purchase flows and you expect to build more than five automations in the first year.

Drip suits independent Shopify brands that want serious workflow depth but do not want to pay for an enterprise platform. Its pricing is built on people and email volume, and the table lists unlimited email sends at most bands, with up to 50 workflows and dynamic segments on the lower tiers. Revenue dashboards help a founder see which flow is producing sales.

Drip has no ongoing free plan, so a store must move to a paid band from the start. Predictive features are lighter than Klaviyo's, and SMS is not the core of the product. A store that runs most of its marketing through email, and wants clear workflows it can edit without a specialist, is the best fit.

At 5,000 people the listed price is $89 a month, and at 25,000 it is $369 a month. Those figures are from the pricing page for those bands; check the band that applies to your exact count before you sign up.

Brevo combines email, SMS and transactional sending in one account, and its free plan allows up to 100,000 contacts with a daily send limit of 300. That makes it useful for a store that wants to keep order confirmations, shipping texts and marketing campaigns under one login and one bill.

Pricing is set by monthly email volume rather than by contacts, so a store with a large list that sends rarely may pay less than one with a small list that sends often. Automation and A/B testing arrive on the Standard plan at $18 a month. Brevo offers less store-specific data mapping than Klaviyo, so product blocks and order details need more manual setup.

Brevo is the strongest pick for a store where margin is tight and SMS is a real part of the plan.

Shopify Email is the lowest-cost way to send store email. The first 10,000 emails each month are free, and beyond that the price is $1 per 1,000 emails. For a new store with a small list, the monthly bill is often zero, which makes it the sensible starting point while the catalog and audience are still small.

Its limitation is depth. Stores that want branching automations, predictive segments, or detailed reporting on each flow will hit those limits sooner than they expect. Because pricing rises with sending volume, a store that sends frequent promotions to a large list should compare the per-email cost against a flat plan from another vendor.

Use Shopify Email for campaigns and a few core messages. Move to a dedicated platform when flows start to carry real revenue.

Mailchimp is the familiar choice. Its free plan covers 250 contacts and 500 sends a month, and the pricing page also lists a 14-day trial of the Standard plan. A new store can connect its Shopify account, send a first campaign and learn the basics before spending anything.

Costs rise by contact band. The Standard plan starts at $20 a month at 500 contacts, $100 for the 2,501 to 5,000 band and $135 for the 5,001 to 10,000 band. Automation depth is shallower than Klaviyo's, so a store that grows into serious cart and post-purchase programs usually moves on.

Mailchimp is a sensible first tool for a debut store. Plan the next move early, while the list is still small.

MailerLite is a low-cost option for small catalogs. Its free plan allows 250 subscribers and 2,500 emails a month. The Comfort plan starts at $12 a month for 500 subscribers, or $10.80 a month billed annually, and includes a monthly email allowance tied to the subscriber tier.

The pricing page does not publish figures above the 500-subscriber starting tier in the data used for this guide, so a store that expects to grow past that should use the calculator on the vendor's site before choosing. Store-specific data mapping is lighter than Klaviyo's, which suits a catalog with a small number of products.

MailerLite fits a small shop that wants popups, welcome flows and campaigns for very little money.

Moosend is a budget platform with cart triggers, product recommendations and unlimited emails on its contact-based Pro plan. For a store on a tight budget, the 500-contact entry price is among the lowest in this guide, and annual billing lowers the monthly figure further.

Its Shopify-specific polish trails the larger platforms. Email credit packs are sold separately for stores that need a fixed volume, and there is no ongoing free plan after the 30-day trial. Check whether the product recommendations and cart triggers cover the flows you want before choosing it over a larger tool.

Moosend is a good pick for a store that wants automated cart recovery at a low, predictable price.

ActiveCampaign suits stores that sell both to consumers and to businesses, or that run a sales process alongside the shop. Its Starter plan includes email marketing, marketing automation, standard CRM and ecommerce integrations. Plus adds standard segmentation and landing pages, and Pro adds advanced segmentation.

The cost of the advanced features is the main issue. Pro is listed at $79 a month at 1,000 contacts, and Enterprise at $145. A pure consumer store with a simple catalog rarely needs that depth, and the extra complexity can slow down the first flows.

ActiveCampaign is a strong choice when the Shopify store feeds a wholesale or B2B pipeline that needs its own deal stages.

Customer.io is built around events: a store sends a message when a specific customer action happens, and it can combine email, push and SMS in one journey. Brands with a data team can connect their own event streams and build journeys that depend on several signals at once.

It is the wrong choice for a store without technical staff. Setup takes longer than the lighter tools, and the price scales with profile count, with the Essentials plan listed at $100 a month and profile-based bands running from $145 at 10,000 profiles to $505 at 50,000 or more. Eligible early-stage companies can receive 12 months free through the Startup Program, which the pricing page describes.

Use Customer.io when the store's own data is already clean and the team can own the event tracking.

Kit suits creator-led brands that sell merchandise, digital products or subscriptions alongside a newsletter. The free plan covers up to 10,000 subscribers, with unlimited landing pages, forms and email broadcasts, plus tagging and segmentation.

Visual automations and sequences start on the Creator plan at $33 a month billed annually, so a store that needs cart or post-purchase flows will pay for that tier. Kit is not built around a product catalog, and a store with a large range of SKUs should look elsewhere.

Kit is a fit for a brand whose audience follows a person more than a product line.

GetResponse is a good fit for stores that run launches, drops or live events. Its tools include landing pages, funnels and webinars, which let a store build a launch sequence without a separate page builder.

Starter includes one automation workflow, so most stores will need the Marketer plan at $59 a month to get abandoned-cart recovery and advanced segmentation. There is no ongoing free plan. For a catalog store that mostly sends standard promotions, the extra tools add cost without much benefit.

Pick GetResponse for event-driven launches and drops, not for everyday catalog email.
