After migrating from WooCommerce to Shopify, your email marketing setup needs to be reconnected. WooCommerce stores typically use Mailchimp, Klaviyo, AutomateWoo, or a combination. Shopify has its own email marketing tool (Shopify Email), and there are dedicated platforms with deep Shopify integration. This guide compares your options to help you choose the right platform.

Migrating from WooCommerce email tools

If you were on Mailchimp

Stay on Mailchimp: reconnect the Shopify Mailchimp app, re-sync your audience
Or upgrade to Klaviyo: Klaviyo can import Mailchimp audiences (email + subscriber status + tags)
Migrate automation flows manually (Klaviyo has a Mailchimp migration guide)

If you were on AutomateWoo

AutomateWoo has no direct Shopify equivalent. Migrate to Klaviyo:

Map AutomateWoo workflows to Klaviyo flows (abandoned cart, win-back, birthday, review request)
Klaviyo has pre-built flow templates for all common AutomateWoo use cases
SMS campaigns: add Klaviyo SMS for AutomateWoo's SMS functionality

If you were on Klaviyo

Reconnect Klaviyo to Shopify (remove WooCommerce integration, add Shopify integration):

In Klaviyo → Integrations → WooCommerce → Disconnect
Integrations → Shopify → Connect → enter your Shopify store URL
Historical order data syncs from Shopify into Klaviyo (up to 5 years back)
All existing flows, segments, templates remain — no rebuild needed
Update flow triggers if any use WooCommerce-specific events

Klaviyo migration to Shopify is the smoothest email platform transition — Klaviyo is already Shopify's most popular integration. Most flows work without changes; just reconnect the integration.

If you were on Brevo (WooCommerce plugin)

Install Brevo for Shopify from the App Store
Connect with your Brevo API key
Customer/contact sync resumes automatically
Configure automation triggers for Shopify events (order placed, abandoned cart)

Recommended setup by store size

Early stage / small stores (under 1,000 customers)

Shopify Email: Free, easy, sufficient for basic campaigns and abandoned checkout
Or: Omnisend free plan (better automation than Shopify Email)

Growing stores (1,000–10,000 customers)

Omnisend ($16–$59/month): Better automation than Shopify Email, SMS included, good value
Or: Klaviyo (more powerful segmentation if budget allows)

Established stores (10,000+ customers)

Klaviyo: Most powerful ecommerce email platform. Predictive analytics, CLV segmentation, advanced automation.
Worth the higher cost for the advanced segmentation and revenue attribution features

Enterprise / high revenue stores

Klaviyo: Strong at scale. Used by major DTC brands including Reformation, Thinx, and many Shopify Plus merchants.

Essential email flows to set up on Shopify

Regardless of which platform you choose, set these up first — they drive the highest revenue per email sent:

Welcome series (new subscriber): 3-5 emails over 7-10 days. Brand story, bestsellers, first-order discount.
Abandoned cart/checkout: Shopify tracks abandoned checkouts. 1-2 emails within 24 hours of abandonment. Recovers 5–15% of abandoned checkouts typically.
Post-purchase thank you: Immediately after order. Confirmation, what to expect, review request at day 7–14 after delivery.
Win-back: Customers who haven't ordered in 90+ days. Special offer to re-engage.
Browse abandonment (Klaviyo/Omnisend): Customer viewed a product but didn't add to cart. Reminder email with the product.

Migration checklist: email marketing

Choose email platform (Shopify Email / Omnisend / Klaviyo based on store size)
If staying on existing platform: reconnect Shopify integration (remove WooCommerce connection)
If switching platforms: import subscribers/contacts with consent status intact
Set up Klaviyo/Omnisend Shopify integration — verify historical order data syncing
Review and update automation flow triggers for Shopify events
Update abandoned cart flow: Shopify uses "Checkout Started" instead of WooCommerce's trigger
Verify transactional emails (order confirmation, shipping) are handled by Shopify Notifications (separate from email marketing)
Send a re-engagement campaign to confirm subscriber list health after migration
Set up list health monitoring: track unsubscribe rate post-migration

The email marketing migration is one where WooCommerce stores often upgrade capabilities in the process. Klaviyo's Shopify integration is more powerful than any WooCommerce email setup — the behavioral trigger data from Shopify (browse events, add to cart, checkout events) enables automations that weren't possible on most WooCommerce configurations.
