Mailchimp Email SMS Marketing

Something needs to be done to keep using my Mailchimp services. I installed this app and everything went well. It only took a few minutes to sync my shop.
I "signed up for our newsletter" to test and everything worked as supposed to.

There is one problem though, I'm not able to access the app from my store, I have to go to the App store where I tap "install" and then I can see my data.

Update: I'm able to access the app directly from my shopify store on my computer, but on mobile (iphone) via the "Shopify app" I get a message "Cannot Authenticate - Please Try Again"

Update 2: New subscribers to my store are being added to my list. Everything seems to work perfect. There’s really no need for me to access the app because everything is being done just like before in the back ground.
I want to thank you for providing a work around. Especially for free.
Shop owners, like me....don’t worry!

So far so good. Their support has been great despite the fact I'm sure they got flooded with inquiries around the May 12 deadline. Answered three of my questions rapidly and thoroughly. Post sync, I also ended up with more subscribers than I originally had, so hopefully there's no major issue there. Regardless, I'm super thankful this app exists because the other solutions were going to burn some serious time, and this app at least provides a bridge in case you want to test the other email solutions while still having a fully functional mailchimp. Thanks ShopSync!

I thin this is a best way, how to solve the problem to property connect Mailchimp and shopify. Everything working good. Technical support is very fast. Highly recommended.

Thank god for this app, as described it fixes the mailchimp syncing issue.

Absolutely crazy that someone had to go and create this app because mailchimp can't get their own act together.

Worked First Time. Great app and very easy to use. Able to sync all orders and contacts with ability to pull in tags as well.

So far, so good. I had problems with error messages and a server issue, probably from everyone changing at the same time, and received a personal and friendly email within 30 secs explaining just that. My numbers remain the same.
The app is free and everything else I looked at switching to was A LOT more expensive.
Thank you ShopSync.

Integrated petzpaws.com Shopify data perfectly to Mailchimp. The process takes time so be very patient. You will be prompted upon completion.

So far so good for my wellness business. I am still learning. Going to watch tutorials to better my understanding. Thanks!

I used this app and was surprised how simple and user friendly it is. The experience was amazing and I strongly recommend others to use it.

Really easy to integrate with my shopify store www.preciousasapearl.com Looking forward to using it effectively!
