Does Shopify integrate with Mailchimp?

What does the Mailchimp app sync with Shopify?

The Mailchimp app, supported by Intuit Mailchimp, syncs:

• Each customer's email, name, order information and custom fields, in near real time except discount codes, which sync every few hours.
• Existing customers' subscription status, then status changes made in Shopify.
• Email and SMS activity, back to Shopify.
• Optionally, new Mailchimp contacts into Shopify.

The first sync can also overwrite consent in Shopify:

Can you import Mailchimp contacts without the app?

Yes, by CSV. Shopify's guide starts from Mailchimp's ZIP export, which holds a separate CSV file for each contact status. The status sets a new Accepts Email Marketing column:

• subscribed_members opted in: enter yes.
• unsubscribed_members opted out: enter no.
• nonsubscribed_members never opted in: enter no.
• cleaned_members can't be contacted successfully, so you don't need to import this file.

Trim each file to five columns (Email Address, First Name, Last Name, Phone Number, Company), rename Email Address to Email and Phone Number to Phone, add Accepts SMS Marketing, then import each file as a customer CSV.

Keep the original exports as your record of when each contact subscribed. A customer CSV can't import order information.

When is Shopify Messaging enough without Mailchimp?

Shopify Messaging, formerly Shopify Email, sends email, SMS and WhatsApp campaigns from your admin on Basic, Grow, Advanced and Shopify Plus, with 10,000 free emails each month (emails sent, not contacts); abandoned checkout automations don't count toward them.

It also runs email and SMS automations. It's enough if your monthly sends fit in those free emails and your automations can live in Shopify: then move your list into Shopify and drop any separate Mailchimp bill. If your segments and automations live in Mailchimp, keep the app.
