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 the most generous free tier. Across the seven apps ranked below, App Store ratings run from 3.6★ 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 transparent subscriber-based pricing, AI-assisted content, and a deliverability focus without the complexity tax.
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.
Boostmail, transparent pricing, AI content, deliverability-first
We made Boostmail because we believe a Shopify store should not pay Klaviyo-tier prices, or restructure its workflow around an enterprise analytics suite, just to run good email and SMS. Boostmail is free up to 1,000 active subscribers (10,000 emails a month, 20,000 AI words included), then scales on a published subscriber-based curve with unlimited emails on every paid plan, $20/mo at 2,500 subscribers, $60/mo at 10,000, $190/mo at 50,000. AI content generation is built in, and deliverability is a first-class feature, not an add-on: sender-reputation monitoring, SPF/DKIM/DMARC setup, and bounce and complaint handling are included.
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: Klaviyo goes deeper on predictive analytics, Avada ships a larger free email allowance, and Privy has a longer track record at on-site capture. If your store needs enterprise-grade cohort modelling above all else, one of those may suit you better. If you want honest pricing, AI help with the actual writing, and email that reaches the inbox, that is the gap Boostmail is built to fill.
- Transparent subscriber-based pricing; unlimited emails on paid plans
- OpenAI-powered content generation included from the free plan
- Deliverability built in, reputation monitoring, SPF/DKIM/DMARC, bounce handling
- Email + SMS, abandoned-cart flows, drag-and-drop builder, segmentation
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 (29 June 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.

Boostmail Our app
Full support for email campaigns · 4.7★ on the Shopify App Store
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.

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.

Omnisend
Full support for email campaigns · 4.7★ on the Shopify App Store
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, with the highest review count of any dedicated email app in this guide. Its pre-built ecommerce automations work out of the box, and SMS credits are included on its higher tiers.
Omnisend edges Boostmail on channel breadth at the top end, web push notifications and an established SMS credit system are baked into the higher Pro tier, where Boostmail keeps SMS simpler.

Klaviyo
Full support for email campaigns · 4.6★ on the Shopify App Store
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, predictive analytics (estimated lifetime value, churn risk), a larger pre-built flow library, and a deeper third-party integration directory. If you live inside cohort reports all day, Klaviyo gives you more dials to turn.

Privy
Full support for email campaigns · 4.6★ on the Shopify App Store
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 sheer track record at on-site capture, it has been refining popups and forms for years and carries one of the largest review counts of any app here.

Drip
Full support for email campaigns · 4.4★ on the Shopify App Store
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 that go further than most stores will ever need, but reward teams that do.

“No free plan, so it gets costly for a small store that is just starting out.”

Mailchimp
Full support for email campaigns · 3.6★ on the Shopify App Store
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.

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 free-tier email volume. Boostmail (our own app) is built for merchants who want transparent subscriber-based pricing, AI-assisted content, and a deliverability focus without Klaviyo-level complexity. 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 (or active subscribers) on your list, so the price rises as your list grows. As of 29 June 2026, Klaviyo runs about $30/mo at 1,000 contacts and roughly $150/mo at 10,000; Omnisend is about $16/mo at 1,000 and $119/mo at 10,000. Boostmail is free up to 1,000 active subscribers, then $20/mo at 2,500, $60/mo at 10,000, and $190/mo at 50,000, with unlimited emails on paid plans. 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, Privy, and Avada all offer free tiers (each capped by contacts and monthly sends, usually with vendor branding on emails). Drip is the exception, it has no free plan. Boostmail is free up to 1,000 active subscribers and 10,000 emails a month with 20,000 AI words included, so a new store can run real campaigns before paying anything.
