Switched to Shopsync after the fall-out between Mailchimp & Shopify. Set-up was very simple and all seems to be working as it should. Worth looking at the article on Mailchimp giving instructions on transferring from their own app to ShopSync which is very helpful.

Here and There Makers

Installed this app based on the Mailchimp instructions and I have to say it works very well. The dashboard actually provides a bit more info than the previous Shopify app and the integration is doing what it says it should. Thank you for providing a neat solution to the MailChimp / Shopify issue.


This was our solution to the Shopify/MailChimp split. Our developer said it transferred our entire email list of about 30k addresses without issue, and seems to be working as advertised, gathering new emails on our website and transferring over to MailChimp.

I love it when things are just simple, and work as advertised. Can't ask for more!

This app worked very easily and quickly. I have only had it for a few days but so far, so good. I love that all my store customers are now automatically in MailChimp for email marketing. This app has been awesome so far.


This integration worked like a charm. Google-search "mailchimp shopsync" for instructions. Here's a link to the guide:

Even Mailchimp recommends this integration. It's a bit unnerving not knowing where this integration comes from, but signs point to Mailchimp having created it, which makes sense as they are surely hoping to minimize loss of customers.

I needed this fast service for a MailChimp workaround. ShopSync was fast, easy, and now I'm ready to move forward. No problems AT ALL!

Easy to install, works great, I am very pleased! Glad Mailchimp suggested your app. Love the look of the pop-up window encouraging people to sign up for my mailing list.

This app is very impressive for linking mailchimp to my store. Made the process seamless, and was very easy to integrate.


Fantastic app. It does exactly what it says. Best way to continue to work with mailchimp. A must for everybody!

This app worked for me as the new Mailchimp integration however, my audience count doubled on the day I installed it. There are no duplicate contacts but the counts are doubled and the analytics for install day show a doubling. What's going on? I hope my audience isn't being hit with double emails. Can someone from support respond? Additionally, can't find a way to communicate with ShopSync support.

I appreciate the explanation of what went wrong. It would be very helpful if you could tell me how to correct the issue.

Hi there, we saw your review and wanted to get in touch. Up until late yesterday (4/3/19), our app was engineered to include past customers who "Accept email marketing", orders, and products in Shopify. If they showed unsubscribed in Shopify, we ignored the email. In other words, we looked at Shopify as the "truth" and nothing else.

Although our intentions for this were done for all the right reasons, it, unfortunately, didn't work for everyone as you saw with your subscriber counts going up. With how we used to perform the initial sync, it would have been possible to re-subscribe users if they had opted out from a Mailchimp list previously. Or, it's also possible the old integration missed real subscribers.

Now, we've changed up how we handle the data from Shopify to Mailchimp on the initial sync. Here's more information on how it works:

Before any data is processed by ShopSync, we perform integrity checks with Mailchimp to ensure these customers can be sent to the list that is connected.

For example, if someone opted out of a list in the past, we won't add the email again. We'll also update Shopify with the correct status that Mailchimp shows. That way, the most current subscriber status in Mailchimp is synced with the store.

After the initial sync is complete, we'll continue adding customers, orders, and products from your store to Mailchimp as transactions occur. We'll add customers that visit your store who are deemed transactional as well. That way, you can use Mailchimp's automations to trigger abandoned carts and order notifications. If someone unsubscribes from a Mailchimp campaign or automation in the future, we'll sync the opt-out status back to Shopify and vice versa.

We sincerely apologize for any inconvenience this may have caused, let us know if you have any follow up questions. We can be reached anytime at
