Email Marketing for WooCommerce: 8 Plugins and Tools Compared (2026)

MailPoet, AutomateWoo, FluentCRM, Omnisend, Klaviyo, Brevo, MailerLite and SendDoggie compared for small WooCommerce stores: pricing checked October 2026, how abandoned cart capture really works with guest checkout, and why your hosting server shouldn't send your campaigns.

Email marketing for WooCommerce works differently from email marketing for a hosted store. Shopify gives every app the same checkout, the same events and the same infrastructure. WooCommerce gives you a WordPress site on hosting you chose, a checkout that plugins can rearrange, and an email function that by default sends through your web server. The tool you pick decides how much of that you have to manage yourself.

This guide compares eight WooCommerce email marketing plugins and services for small stores: what each costs on the vendor's own pricing page, how it connects, which store automations it runs, where your email is actually sent from, and what tends to go wrong. If you're leaving a specific platform, our Klaviyo alternatives and Mailchimp alternatives guides cover those moves in more depth.

What's different about WooCommerce email

Plugin-based vs SaaS-based tools

WooCommerce email tools come in two shapes. Plugin-based tools (MailPoet, AutomateWoo, FluentCRM) store your contacts, build your emails and run your automations inside WordPress, in your own database. SaaS-based tools (Omnisend, Klaviyo, Brevo, MailerLite, SendDoggie) keep all of that on the vendor's platform; a connector syncs customers, orders and products across, and you work in the vendor's dashboard.

Plugin-based tools keep everything in one admin and usually cost less, but they add load to your hosting and you own the upkeep. SaaS tools move that work off your server, at the price of another login, another bill and a sync that can drift.

Where the email is sent from

By default, WordPress sends mail through wp_mail(), which hands the message to PHPMailer and, without an SMTP plugin, to your server's own mail setup. WordPress's own source notes that a successful send "does not necessarily mean that the recipient(s) received the email successfully" (wp_mail reference). On shared hosting, that server's IP address is shared with many other sites, some of which may send spam, and the host often limits how many emails an account can send per hour.

That's tolerable for a few order confirmations a day. For a campaign to a few thousand people it means throttled batches that take hours, an IP reputation you don't control, and often no proper DKIM signature for your domain. Gmail requires every sender to have SPF or DKIM, and bulk senders (5,000 or more messages a day to Gmail) to have SPF, DKIM, DMARC with alignment and one-click unsubscribe (Gmail sender guidelines). The fix is a dedicated sending service: a SaaS platform's own infrastructure, or an SMTP provider behind a plugin. Our guide to why emails go to spam covers the reputation side.

Consent at checkout

WooCommerce doesn't add a marketing opt-in to checkout by itself; your email tool's plugin does. Under GDPR and similar laws, buying something isn't consent to newsletters, so the checkbox should be unticked by default and its state stored against the contact. Order and shipping emails don't need it. Campaigns do.

Guest checkout and cart capture

An abandoned cart email needs an email address, and a guest shopper who adds to cart and leaves hasn't given you one. Omnisend's documentation says anonymous visitors can't trigger abandoned cart emails at all, and that an email typed at checkout counts only for abandoned checkout (Omnisend). Klaviyo tracks Started Checkout for a guest once they view checkout and enter a billing email (Klaviyo). FluentCRM starts tracking on the checkout page once a billing email is available (FluentCRM). AutomateWoo has an optional pre-submit capture setting that collects billing details before the order is placed (AutomateWoo). In practice, WooCommerce "abandoned cart" usually means abandoned checkout by a shopper who typed their email.

What a small WooCommerce store actually needs

List what you'll actually run in the next year. For most stores with one person on marketing, it's this:

• Abandoned checkout recovery that captures the email at checkout and stops when the order is placed. See our abandoned cart email guide.
• A welcome series for new subscribers and a separate one for first-time customers (welcome sequence guide).
• Post-purchase and review request emails timed to delivery, not to the order (post-purchase guide).
• A win-back email for customers who haven't ordered in a set period.
• Product blocks that pull images, prices and links from your catalogue.
• Sending that isn't your hosting server, with SPF, DKIM and DMARC on your domain and one-click unsubscribe.
• A checkout consent checkbox that records who opted in.

Anything beyond that, such as SMS, predictive analytics or a full CRM, is worth paying for only if you'll use it this year.

The 8 tools at a glance

USD prices as shown on each vendor's pricing page in October 2026. Plugin statistics are from WordPress.org on 16 October 2026.

Why Mailchimp isn't here: the official Mailchimp for WooCommerce plugin is still maintained (version 6.3, last modified 23 September 2026, 200,000+ active installs), but its own page says product category sync isn't supported by the Mailchimp API, non-opted-in customers are added as "Transactional" contacts that can't be exported, and sync depends on WP-Cron. With Mailchimp also billing for unsubscribed contacts (see our Mailchimp alternatives guide), it's a poor fit for a small store choosing today.

The tools in detail

1. MailPoet

MailPoet is the closest thing to a WooCommerce-native newsletter plugin. Its WordPress.org page lists MailPoet, WooCommerce and Automattic as contributors, and the MailPoet site footer reads "An Automattic oeuvre". On 16 October 2026 the plugin showed 500,000+ active installs, a 4.4 rating from 1,432 reviews, and an update three days earlier. Sending goes through the MailPoet Sending Service or a method you choose; the plugin page itself calls sending from your own host "not recommended".

The MailPoet pricing page lists a free Starter plan for up to 500 subscribers and 5,000 emails a month through its sending service, and Business at $10/month for 500 subscribers ($30/month at 2,500), adding segmentation, targeted automation and no MailPoet branding. A Creator plan ($8/month at 500 subscribers) has Business features without the sending service, for stores bringing their own SMTP.

Pros: one admin, a checkout opt-in, products in emails, and a customizer for WooCommerce order emails.

Cons: the plugin page puts win-back emails and review follow-ups on paid plans. Automation queues run in your database, so cheap hosting will feel it.

Who it's for: stores that want to stay inside WordPress and are happy on the MailPoet Sending Service.

2. AutomateWoo

AutomateWoo is a WooCommerce extension sold by Woo on the WooCommerce Marketplace: version 6.9.3 was current in October 2026, and a June 2026 update added cart status tracking and MailPoet template styling. It's an annual subscription; the marketplace showed us a price in local currency, so check it in yours.

It's a workflow engine, not a newsletter tool: abandoned cart, review requests with optional rewards, win-back and product follow-ups. Carts are marked abandoned after 15 minutes of inactivity by default, and guest emails can be captured before checkout is submitted.

Pros: deep access to WooCommerce data and coupons, with no per-contact pricing.

Cons: no campaign or newsletter tool, and no sending service of its own. Emails use the WooCommerce email template and go out the way your store's other mail does, so pair it with an SMTP plugin and a proper sending provider.

Who it's for: stores already using MailPoet or another newsletter tool that want more control over store-triggered emails.

3. FluentCRM

FluentCRM is a self-hosted CRM and email plugin from WPManageNinja. Its WordPress.org page showed 80,000+ active installs, a 4.8 rating from 250 reviews and an update on 12 October 2026. The core plugin is free with no contact or email limits; the page lists WooCommerce under Pro integrations. On the FluentCRM pricing page, Pro is priced per site: Solo/Blogger at $129/year for one site (shown discounted to $90 when we checked), Small Business at $249/year for five sites.

WooCommerce triggers include new order, order completed, refunded and status changed, plus abandoned cart tracking that begins once a billing email is available on checkout.

Pros: flat pricing however large the list grows, and full ownership of your data.

Cons: FluentCRM doesn't send email itself. You connect and pay for an SMTP or sending service such as Mailgun or SendGrid, and everything else runs on your server.

Who it's for: technically comfortable owners, or stores with a developer, on decent hosting.

4. Omnisend

Omnisend is an ecommerce-first SaaS platform with email, SMS and push. Its WooCommerce plugin showed 40,000+ active installs and a 4.9 rating from 169 reviews, last updated 16 September 2026. The Omnisend pricing page lists Free (250 contacts, 500 emails/month, with ecommerce workflows including cart abandonment), Standard at $11.20/month for 500 contacts and Pro at $41.30/month for 2,500 contacts, both with 30% off when you prepay three months; the undiscounted totals shown work out to $16 and $59 a month. Omnisend bills for subscribers and non-subscribers who received automated messages, not unsubscribes.

Pros: prebuilt abandoned cart, checkout, welcome and post-purchase workflows on every plan, product blocks with live prices and stock, and review app integrations.

Cons: abandoned cart (as opposed to checkout) only reaches shoppers already identified by a click, a form or a previous order. Free requires Omnisend branding.

Who it's for: stores that want ready-made ecommerce flows and possibly SMS, without running anything on their server.

5. Klaviyo

Klaviyo's WooCommerce plugin showed 100,000+ active installs but a 2.8 rating from about 25 reviews, last updated 17 August 2026. It syncs orders, products and checkout events, and includes a marketing consent checkbox for checkout. The Klaviyo pricing page lists a free plan with up to 250 profiles and 500 emails a month; paid prices come only from a calculator.

Pros: the deepest segmentation and reporting here.

Cons: profile-based billing grows with every checkout, and most small stores won't use the depth they pay for. Our Klaviyo alternatives guide covers the billing in detail.

Who it's for: growing stores with someone who has time to build segments and read reports.

6. Brevo

Brevo prices on email volume rather than contacts. The Brevo pricing page lists Free at up to 300 emails a day once your account is approved, Starter at $9/month from 5,000 emails a month, Standard at $18/month and Professional at $499/month. Multi-step automation is listed under Standard, so budget for it if you want abandoned cart workflows. Its WordPress plugin showed 100,000+ active installs and a 4.1 rating from 284 reviews, but was last updated 24 June 2026 and tested only up to WordPress 6.9.10.

Pros: a large, quiet customer list doesn't raise the bill, and the plugin can also send WooCommerce order emails through Brevo's SMTP.

Cons: the plugin's release pace lags WordPress, and the page doesn't mention product blocks.

Who it's for: stores with big customer lists that send moderately, and anyone who also wants order emails off the hosting server.

7. MailerLite

MailerLite's pricing page lists Free (250 subscribers, 2,500 emails/month), Comfort from $12/month and Power from $25/month, and its comparison includes ecommerce triggers for abandoned cart and abandoned checkout workflows. The WooCommerce plugin adds a checkout checkbox, product import and order data sync, but on 16 October 2026 it showed 30,000+ installs, a 2.8 rating from 64 reviews, and a warning that it hasn't been tested with the latest three major WordPress releases.

Pros: a clean editor and an approachable automation builder at a low entry price.

Cons: MailerLite's abandoned cart announcement says guest customers can't trigger the abandoned cart workflow because they only enter their email at checkout, and that marketing consent is required. Plugin reviews report unreliable abandoned carts and duplicate entries after an update.

Who it's for: newsletter-led stores where abandoned cart recovery is secondary.

8. SendDoggie

SendDoggie is our product, so read this entry accordingly. It's built for small ecommerce teams and connects to WooCommerce (and Shopify), syncing products so you can drop product blocks into emails. Store-triggered sequences cover abandoned carts, product review requests and welcoming new customers. Magic Email drafts a branded email from a product URL and a short prompt, alongside a drag-and-drop designer with starter templates and true plain-text campaigns with switchable click tracking. Domain authentication is guided: it detects your DNS provider and live-checks each record. Email is sent from SendDoggie's sending infrastructure, not your WordPress server. Plans are on the pricing page.

Pros: the core store flows and product blocks without adding mail load to your hosting, and authentication that's hard to get wrong.

Cons: a newer platform with a smaller integration ecosystem, email only (no SMS), and it's an external service rather than a dashboard inside WordPress.

Who it's for: small WooCommerce stores that want campaigns and the main store flows sent properly, without managing SMTP. You can test it with a free account.

How the pricing models compare: a worked example

The store and numbers in this example are illustrative, not data from any real business or vendor. Picture a WooCommerce store with 5,800 email addresses: 2,000 opted-in subscribers, 3,000 past customers who never ticked the marketing box, and 800 unsubscribed. It sends four campaigns a month to the 2,000 subscribers (8,000 emails) plus about 1,000 automated emails.

• Per-site licence (FluentCRM, AutomateWoo): a fixed yearly fee whatever the list size, plus a separate sending provider billed on volume, plus whatever your hosting needs to cope.
• Subscriber tiers (MailPoet, MailerLite): you pay for roughly 2,000 subscribers. Non-consented customers needn't be in the list at all. On MailPoet's Business tiers that sits between the 1,500 and 2,500 levels.
• Contacts reached (Omnisend): the 2,000 subscribers plus any non-subscribed customers who got an automated email that month, such as a post-purchase message.
• Active profiles (Klaviyo): anyone emailable counts, so the 3,000 non-consented customers are billed alongside the subscribers, putting the store near 5,000.
• Email volume (Brevo): about 9,000 emails a month, on a plan that includes automation. Doubling the customer list changes nothing unless sends grow.

Rerun the numbers with the list doubled. The cheapest option today often isn't in a year, and a "free" plugin isn't free once you add a sending provider and better hosting.

Which tool fits which store

• Want everything inside WordPress, little setup: MailPoet on its sending service.
• Need fine control over store-triggered emails: AutomateWoo, alongside a newsletter tool.
• Large list, technical owner, flat cost: FluentCRM plus a sending provider.
• Ready-made ecommerce flows, maybe SMS: Omnisend.
• Deep segmentation and reporting, time to use it: Klaviyo.
• Big customer list, moderate sending, order emails too: Brevo.
• Campaigns and core store flows sent off your server, with guided DNS: SendDoggie is worth a test.

Setup checklist

• Consent checkbox at checkout, unticked by default, wording that names marketing emails, and the result synced to your tool.
• Sending domain authenticated: SPF, DKIM and DMARC on the domain in your From address, aligned with whatever actually sends.
• Customers and past orders synced, with non-consented customers kept out of campaigns. Check the order count in the tool against WooCommerce.
• Suppressions first: import unsubscribes, bounces and complaints from any previous tool before customers.
• Abandoned cart timing set: first email about one to four hours after abandonment, a second around a day later, exit on purchase.
• Test with a real order: use a new email address as a guest, abandon checkout, wait for the email, then complete the purchase and confirm the sequence stops and post-purchase emails start.
• Unsubscribes honoured everywhere, including in any plugin that syncs contacts back into WordPress.

Your SPF record must include every service that sends as your domain, in a single record:

example.com.         TXT  "v=spf1 include:_spf.your-mailbox-host.example include:your-sending-service.example ~all"
_dmarc.example.com.  TXT  "v=DMARC1; p=none; rua=mailto:dmarc-reports@example.com"

Two separate v=spf1 records make SPF fail, and each include counts toward SPF's limit of 10 DNS lookups. Start DMARC at p=none, read the reports to confirm every sender passes, then tighten. Our deliverability guide walks through each record.

Common mistakes

Sending bulk email from the hosting server

Leaving a plugin-based tool on the host's default mail is the most common WooCommerce email mistake. Campaigns trickle out under the hourly cap, land in spam on the shared IP's reputation, and can get the account suspended.

Importing every customer as a subscriber

A customer export isn't a marketing list. Mailing customers who never opted in raises complaints and breaks GDPR; keep them out of campaigns and ask for consent after purchase.

Duplicate transactional and marketing emails

WooCommerce already sends order confirmation, processing and completed emails. If your marketing tool also sends a "thanks for your order" email at the same moment, customers get two. Decide which system owns each message and make marketing emails start a day or more after the order.

Plugin conflicts and caching that break cart capture

Cart capture relies on JavaScript and AJAX on the cart and checkout pages. Page caching, script minification or a custom checkout plugin can stop it firing without any error. Exclude cart, checkout and my-account pages from caching, and retest after every checkout or theme change.

Troubleshooting

Abandoned cart emails aren't firing

Check, in order: the automation is active; the shopper was identifiable (a guest who never reached the email field can't be emailed); the shopper is subscribed if the tool requires it; the checkout page isn't cached; and the plugin's connection is still authorised. Retest with a brand-new address.

Emails land in spam

Open a received email in Gmail, choose "Show original" and look for spf=pass, dkim=pass and dmarc=pass. If DKIM is signed by the sending service's domain rather than yours, finish domain authentication. If the Received headers show your hosting server, the email isn't going through your sending service at all. See why emails go to spam for content and reputation causes.

The sync is missing orders or customers

Compare counts for a recent date range. Gaps usually come from the historical sync timing out on shared hosting, expired API keys, or orders created by a plugin that skips the usual WooCommerce hooks. Rerun the sync at a quiet time and check the plugin's log.

Emails are late or arrive in bursts

WP-Cron isn't a real scheduler. WordPress's documentation says it "is only triggered on page load", so on a low-traffic store, scheduled emails and syncs wait for the next visitor (WP-Cron docs). If your host offers a server cron, disable the page-load trigger and call WP-Cron on a schedule (WordPress guide):

// wp-config.php
define( 'DISABLE_WP_CRON', true );

# server crontab: every 5 minutes
*/5 * * * * wget -q -O /dev/null "https://example.com/wp-cron.php?doing_wp_cron" >/dev/null 2>&1

SaaS tools that receive events from WooCommerce in real time are less affected, but their initial syncs can still rely on WordPress's scheduled tasks.

Key takeaways

• Decide first where email is sent from. Marketing email from shared WordPress hosting is the root of most WooCommerce deliverability problems.
• Plugin-based tools are cheaper and live in WordPress; SaaS tools take load and upkeep off your server.
• "Abandoned cart" usually needs an email, so test each tool with a fresh guest checkout.
• Keep non-consented customers out of campaigns and use an unticked checkout checkbox.
• Model costs on your own list and send volume, including a sending provider for self-hosted plugins.
• Check plugin health on WordPress.org: last updated, tested-up-to version and recent reviews.

Shortlist two tools, connect them to a staging copy of your store, and run the same guest checkout test through both before you move your list.
