Migrating to a new ESP may feel daunting and stressful, but you can ensure a smooth transition by following step-by-step instructions and our best practices. Unlike with other Email Providers, we have a built-in integration with MailChimp, that will help you migrate your data promptly.

In this article, we will go through all of the steps of the migration process. And more, we've also created Mailchimp Migration Resources Hub for Shopify merchants, check it out to find all news about migration, new Mailchimp feature requests we are releasing, feature comparisons with Mailchimp, or Klaviyo, and more. 

Important! We do not recommend closing your MailChimp account before you transfer all of the data, re-create your automation workflows, and make sure everything works as intended.

Integration of E-commerce Platform

You need to integrate your store to start benefiting from Omnisend e-marketing features. We can integrate with the following platforms:

The easiest way to integrate your Shopify store with us is to download Omnisend app in the Shopify app store and follow the instructions there. You will be redirected to Omnisend app, asking you to create an account with Omnisend

Note, only one store can be integrated with one Omnisend account.

Migrating Contacts from Mailchimp

Once you connect your store to Omnisend, all of the contacts, orders, products, carts, etc., are being imported to your Omnisend account. The synchronization time for each of the platforms is different and may take from 1 to 24 hours.

However, apart from the information synced from your store, we also need to transfer the data collected with MailChimp. Our built-in integration enables you to skip the selection of attributes.

You will need to take the following steps to import your subscribers:

  1. Generate an API key in your Mailchimp account.
  2. Go to Omnisend account > Audience > Add contacts
  3. Choose Mailchimp > paste the API key you generated > click Continue 
  4. Send contacts to a list by using a tag or creating an automated segment

Or you can follow the steps in your own pace while reading Importing subscribers from Mailchimp article.

What is great, that you can import any custom data or tags you collected about your customers while using Mailchimp!
