Best Shopify email marketing apps (2026)

For most Shopify stores in 2026, Klaviyo, Omnisend, and Avada Email Marketing are the strongest off-the-shelf email marketing apps, Klaviyo for analytics depth, Omnisend for bundled email and SMS, Avada for low-cost breadth. Across the seven apps ranked below, App Store ratings run from 4.5★ to 4.8★, and pricing at roughly 10,000 contacts ranges from about $47 a month (Avada) to about $154 (Drip). Boostmail, the app we build, is our disclosed pick for stores that want to keep every subscriber and pay only for what they send: no charge per contact, and the first 20,000 emails every 30 days are free.

Below, every app that ships email campaigns on the Shopify App Store is ranked by a transparent, data-only criterion, App Store rating, highest first, followed by a per-app breakdown of where it wins, what it costs, and what its own users flag as weak. Every figure is sourced from each app's Shopify listing and dated; competitor criticisms are quoted verbatim from real reviews, never asserted by us.

Our pick, disclosed We build Boostmail, and we say so.

Boostmail, keep every subscriber, pay only for what you send

We made Boostmail because we believe a Shopify store should not pay more just because its list grew. Boostmail never charges per contact, so there is no reason to prune your list: the first 20,000 emails every 30 days are free, and after that you pay per 1,000 emails sent. For 10,000 contacts receiving 4 emails each per 30 days, that is $15; for 50,000 contacts, $95. You get a drag-and-drop editor with preset templates, segmentation, two-way Shopify sync of customers and email consent, abandoned cart and welcome emails, and domain authentication (SPF, DKIM, DMARC) with automatic bounce and complaint handling.

We rank Boostmail by the same rule as every other app on this page, its App Store rating, and we are upfront about where rivals beat it: Boostmail is email only, with no SMS, no popups (our separate BoostPop app covers those), and no flow builder beyond its three triggered campaigns. Klaviyo and Omnisend offer SMS and full flow builders, Klaviyo goes deeper on predictive analytics, and Privy has a longer track record at on-site capture. If your store needs those, one of them may suit you better. If you want a simple email app whose bill follows what you send, not how many contacts you keep, that is the gap Boostmail is built to fill.

  • Pay per email sent, never per contact; first 20,000 emails every 30 days free
  • Two-way Shopify sync of customers and email consent, plus Shopify segment import
  • Domain authentication (SPF, DKIM, DMARC), bounce and complaint suppression
  • Drag-and-drop editor, segmentation, abandoned cart and welcome emails

How we ranked these apps

We start with every app on the Shopify App Store that actually ships email campaigns today, not "coming soon" features. We then order them by a single, stated rule: category fit first (full support before partial), then App Store rating, highest first. No placement fees, no pay-to-rank. Boostmail is our own app and is ranked by exactly the same rule.

Every price, rating, and review count is read directly from each app's Shopify App Store listing and recorded with the date it was verified (30 September 2026 for this edition). Competitor weaknesses are reproduced verbatim from real user reviews with a link and date, we never paraphrase a criticism into our own assertion. Trademarks belong to their respective owners; this guide is independent and unaffiliated.

The ranking: 7 Shopify email marketing apps

Ordered by App Store rating, highest first. Boostmail is our own app (disclosed). Each competitor entry includes a sourced strength, where it beats Boostmail, and a verbatim quote from a real user review.

  1. Mailchimp

    Full support for email campaigns · 4.8★ on the Shopify App Store

    View listing

    Best for merchants already standardised on Mailchimp elsewhere

    Mailchimp is the most widely recognised email brand and carries an enormous template library, a familiar campaign editor, and a broad marketing suite that reaches beyond Shopify. If your team already runs Mailchimp for a newsletter or another channel, the learning curve is near zero.

    Mailchimp beats Boostmail on brand familiarity and template volume, its drag-and-drop editor and template gallery are vast, and many merchants already know the interface.

  2. Avada Email Marketing

    Full support for email campaigns · 4.8★ on the Shopify App Store

    View listing

    Best budget pick for email, SMS, and popups in one app

    Avada Email Marketing offers one of the most generous free tiers in the category, 12,000 emails a month with basic automations and lead-capture popups at no cost, and earns a high App Store rating. For a store testing email for the first time, it is an inexpensive way to start.

    Avada beats Boostmail on breadth for the price: its free plan includes lead-capture popups and basic automations, and its Pro plan adds SMS, WhatsApp, and unlimited flows. Boostmail has no SMS, popups, or flow builder, though its free allowance is larger (20,000 emails every 30 days, with no charge per contact).

  3. Boostmail Our app

    Full support for email campaigns · 4.7★ on the Shopify App Store

    View listing

    Boostmail is the app we build, so we keep our own description short and let the disclosed pick card above and the comparison table do the talking. In brief: pay-per-send pricing with no charge per contact (the first 20,000 emails every 30 days are free), a drag-and-drop editor with segmentation and two-way Shopify sync, abandoned cart and welcome emails, and domain authentication with automatic bounce and complaint handling. It has no SMS, popups, or flow builder. We rank it here by its App Store rating, the same rule applied to every other app, and we are explicit about where rivals go deeper.

  4. Klaviyo

    Full support for email campaigns · 4.7★ on the Shopify App Store

    View listing

    Best for data-heavy stores that have outgrown a simpler tool

    Klaviyo is the most established email and SMS platform on the Shopify App Store, with the deepest analytics, predictive segmentation, and a vast template and integration ecosystem. For a store with a large catalogue and a dedicated marketer, no other app matches the granularity of its reporting.

    Klaviyo beats Boostmail on raw breadth: SMS (Boostmail has none), a full flow builder with pre-built flows (Boostmail offers three triggered campaigns), predictive analytics such as estimated lifetime value and churn risk, and a deeper third-party integration directory. If you live inside cohort reports all day, Klaviyo gives you more dials to turn.

  5. Omnisend

    Full support for email campaigns · 4.7★ on the Shopify App Store

    View listing

    Best for merchants who want email and SMS tightly bundled

    Omnisend is purpose-built for ecommerce and bundles email, SMS, and push into one automation canvas. Its pre-built ecommerce automations work out of the box, and SMS credits are included on its higher tiers.

    Omnisend beats Boostmail on channel breadth: it bundles email, SMS, and web push in one automation canvas, and SMS credits come with its higher Pro tier. Boostmail is email only, with no SMS and no flow builder.

  6. Privy

    Full support for email campaigns · 4.5★ on the Shopify App Store

    View listing

    Best for stores whose priority is on-site list growth

    Privy is one of the most-reviewed apps in the entire category and is genuinely strong at the top of the funnel: its popups, spin-to-win wheels, and on-site forms are mature and convert well. For a store whose first job is capturing email addresses, Privy is hard to beat on lead capture alone.

    Privy beats Boostmail on on-site capture: it has been refining popups and forms for years and carries one of the largest review counts of any app here. Boostmail has no popups of its own; our separate BoostPop app covers that.

  7. Drip

    Full support for email campaigns · 4.5★ on the Shopify App Store

    View listing

    Best for ecommerce stores that want a powerful workflow builder

    Drip is an ecommerce-focused ESP with a flexible, branch-heavy automation builder and strong behavioural segmentation. Marketers who want to model intricate customer journeys, and are willing to invest the time to build them, get a lot of control.

    Drip beats Boostmail on workflow depth for power users: its visual builder supports complex multi-branch journeys, where Boostmail offers only three triggered campaigns (abandoned cart, welcome, and coupon reminder) and no flow builder.

Frequently asked questions

What is the best email marketing app for Shopify in 2026?
There is no single best app for every store, it depends on your list size, budget, and how much analytics depth you need. Klaviyo leads on raw analytics and integrations, Omnisend on bundled email and SMS, and Avada on low-cost breadth. Boostmail (our own app) is built for merchants who want to keep every subscriber and pay only for what they send: there is no charge per contact. It is email only, with no SMS and no flow builder, so stores that need those should look at Klaviyo or Omnisend. The ranking on this page orders every app that ships email campaigns by App Store rating; use the comparison table to weigh them against your own requirements.
How were these apps ranked?
We include every app on the Shopify App Store that actually ships email campaigns today, then order them by category fit first (full support before partial) and App Store rating second, highest first. We do not rank apps by how much they pay us, we accept no placement fees, and Boostmail is ranked by the same rule as everyone else. Every price, rating, and review count is taken from each app's own Shopify App Store listing and dated so you can re-check it.
Why is Boostmail included in its own ranking?
Boostmail is our app, and we disclose that openly at the top of the list and in the disclaimer. Leaving it out would be less honest than including it on the same transparent criterion as every competitor. It ranks where its App Store rating places it; the competitor blurbs below describe, in our own words, where each rival genuinely beats Boostmail, and every competitor criticism is a verbatim quote from a real user review, never our characterisation.
How much do Shopify email marketing apps cost?
Most charge by the number of contacts on your list, so the price rises as your list grows. As of 30 September 2026, Klaviyo runs about $30/mo at 1,000 contacts and roughly $150/mo at 10,000; Omnisend is about $20/mo at 1,000 and $132/mo at 10,000. Boostmail charges per email sent instead, never per contact: the first 20,000 emails every 30 days are free, then you pay per 1,000 emails. With each contact receiving 4 emails per 30 days, that is $0 for 1,000 contacts, $15 for 10,000, and $95 for 50,000. Always confirm current pricing on each vendor's listing, since these figures change.
Do any of these apps have a free plan?
Most do. Klaviyo, Omnisend, Mailchimp, and Avada all offer free tiers, each capped by contacts and monthly sends. Privy and Drip are the exceptions: neither has a free plan, only a free trial. Boostmail's first 20,000 emails every 30 days are free, with no charge per contact, so a new store can run real campaigns before paying anything.
