There is no single best Shopify email app. The right one depends on your list size, your order volume and whether you need SMS. Below are five apps we think are worth a look, with the facts that matter: free plan limits, how the bill grows, and what each one is good at.
Disclosure: EmailSync is our app. We include it because it fits some stores well, and we are clear about where it does not.
Recover abandoned carts on Shopify, starting free
EmailSync starts you with a 3-step cart recovery template you can fully edit in its flow builder. Each email shows the shopper's real cart, it stops when they buy, and you see the revenue each email brought back.

Mailchimp
Free under 250 contacts, but without automation flows. Essentials allows flows of up to 4 steps. Standard allows up to 200 flows and sends of 12 times your contact count. A good pick if your business already runs on Mailchimp.
EmailSync
EmailSync is built around the flows that bring in money. One click adds a 3-step abandoned cart flow with each shopper's real cart items that stops when they buy, and every step is editable in the visual flow builder: timing, extra emails, if/then conditions, open and click branches, tags and discount codes. Welcome, order follow-up and product recommendation templates are included. You can trigger flows when someone buys a specific product, tag those buyers, and send campaigns to any tag or list. A/B testing and a custom sending domain are included too. Every paid order is matched to the email that drove it, so you can see what each email earned. AI agents can draft campaigns over MCP.

| Starter (shown as Pro on the App Store) | $19.95 | Up to 500 | 25,000 |
