Mailchimp: Email & SMS

I had been using this app since it was Shop Sync when Shopify and Mailchimp split up. Suddenly this past Sunday 3979 contacts were deleted from my mailing list. I just discovered this tonight and they are telling me to make a new list and resync all the contacts. This does not fix the problem because all these contacts had already updated preferences about which emails to get and discovering this the night before I launch a project 7 years in the making has me fuming. I will be leaving Mailchimp, I had been a customer since 2008. All they are saying is we know this is unsettling. This is a bug on their end but the small businesses are paying the price. Total Garbage. I just want all my contacts back so I can export the list to a new company. The other thing I just realized is syncing the contacts again could cause some folks who have unsubscribed to get emails again, which then flags the account and causes more problems.

I can't even get on the page within Shopify to upgrade to get help because it isn't recognizing me and I am the only administrator. Where am I to get help?
Also - re the removing the opt-in at checkout and making a comment on the page to ask customers to re-check the opt-in - - shopify doesn't let you edit the content in the cart at all from what I understand.

This app has one major flaw - it unsubscribes your most engaged followers when they purchase from your store, unless they re-tick your receive emails button. They are aware of this and don't see it as a big issue, however it requires a lot of admin to manually undo it.

REALLY frustrated :( i checked through mailchimp and shopify and shopsynce and see this: Features
Sync customers
Purchase activity segmentation
E-commerce tracking and reports
Product content block
Product Recommendation content block
Promo Code content block
Order notifications
Abandoned cart email
Abandoned cart postcards
Product retargeting email
Pop-up signup forms
Google remarketing ads
Sync merge tags

but when i am in mailchimp creating a campaign, there are no product blocks!
when i input an image, it allows me to select from my product list, but doesn't synce the link to the product or any product info (price/name/etc)

i don't think i should have to upgrade to ask why a free feature isn't available. please help:(

Glitch in app that can cause wildly inflated bill. Reported the issue to mailchimp who said there is no way to prevent shopify from unarchiving currently archived contacts. For us that meant a one day spike in the number of our active customers. That meant a bill that went from just over $100 a month to over $800 for a month. Watch out for this glitch or you may be overcharged yourselves.

I am going to beg everyone to take a closer look at your data after installing this app. I have had quite spotty performance with ShopSync over the past 5-7 days. The initial install was seamless with all data syncing just fine. No problems with the baseline — the problem is going forward. I am using a plain-vanilla install of the Debut theme. The vast majority of my new subscribers are not porting to Mailchimp and there is just no rhyme or reason that I can discern with respect to which new subscribers will sync and which will not. In an effort to fix the problem, I uninstalled the app and re-installed it more than once between March 21 and March 25. On March 27 I had to force resync to get my new subscribers to move over to my list in MailChimp. However, all data for a test purchase through the Shopify site did port to Mailchimp just fine as well as data from a real purchase just today. On March 28, 71% of my new subscribers did not sync to Mailchimp. Today, March 29, over 60% of my new subscribers have not synced to Mailchimp. If the sync is supposed to be running continuously in the background, it does not seem to be working for me.

I use this app to send out welcome letters to my subscribers and it’s never sync. Out of about 50 subscribers only 4 emails went out. To me it’s no point in having the app

For all last week trying to reconnect to my account but my emails and articles aren't there contacted several times support but each time received answers
with questions rather than answers!
Not abel to contact by phone although I have paid for pro account $90.00
No phone number exist?

Lost over 10k of my audience somehow as Mailchimp have moved away from Shopify then back after buying ShopSync. Very dissapointed to say the least! :( **UPDATE** I am not sure why they have edited the review to make it seem like there is a solution. After going back and forth with a rude customer service agent who took 24hours to reply and made it seem like my fault, they finally offered me £50 - As if this fixes the 2-5k audience loss i have had. I WANT A SOLUTION! How embarrasing i carried on using this app when there is so many better options out there. In my stupidity i thought mailchimp has been around for so long they would be the best choice. BAD idea! **Mailchimp, the developer of Mailchimp, edited their reply to your review on the Shopify App Store. Here’s their updated reply: Hi SLAPSTA, thanks for your patience while we researched your comments. By chance, did you have the old (Legacy) Mailchimp for Shopify app installed previously? If so, and it was deleted recently, that would've caused data to be "deleted" in Mailchimp. We realize the inconvenience and frustration this has caused and have made an update to the legacy application to eliminate this behavior going forward.
The good news is that resyncing your store should fix any missing data. We'll grab your customer's order information and opt-in preference and sync them with your Audience. Follow this guideline for set up: https://mailchimp.com/help/connect-shopify/. Please reach out to our support team anytime if you see anything different after a resync is completed and we will be happy to help!

Used to be good and for a great price, but have continuously increased the pricing so that they are now one of the most expensive for fewer extras than their competitors. Have been with Mailchimp for over 7 years, but the last price hike was one too many I'm afraid. Now moving to another company!
