No Support - The functionality looks awesome and the email builder looks good. However you get NO CUSTOMER SUPPORT. No phone number, no chat, just an email that they never respond timely too. Also the notifications do not work with bigcommerce even though they are suppose too

Integration - Used to work, then out of know where it stopped and customer service is almost stagnate. You think they would easily define what version of API key you are using without deleting app and reinstalling. Looking for a new app for my email campaigns.

No customer support - I have heard of MailChimp in the past and wanted to give it a try. Unfortunately, there is absolutely no support. You can not call or email the company without buying a plan first. Once I purchased a plan the support was still not available. I have requested a refund and have not heard back in several days. Now going to dispute the charge on my credit card. Very poorly designed APP. Beware!!!

Integration no longer works. - I get an error when I try to verify the new API key. It seems that the app is outdated and no longer works with Mailchmip's new API keys. AS a result, my subscribers from the BigCommerce and Mailchimp cannot be synced.

MailChimp is great but no tracking in confirmations?! - I have been a long time MailChimp user and love the application but they have really missed it on not having tracking information in the shipping confirmation emails. I don't even know why you would have shipping confirmation emails without sending out the tracking number. Come on MailChimp, you can do better.

New MailChimp API 3.0 - Since the 1/Apr/2019 The old APP needs to be removed and installation initiated from MailChimp.If you are receiving error messages stating that you are not up-to-date, this is caused by the legacy integration still being connected. To resolve these error messages, you will want to go to your BigCommerce Dashboard and navigate to Marketing > Email Marketing, then disable the MailChimp integration from here. Hope this information helps!

Store no longer synching - As another customer has pointed out, Mailchimp has shut down API 1.1, 1.2, and 1.3 meaning emails no longer sync and my customers, like myself, are getting pissed off.

Easy to use and free - Hard to complain about a free app. But I had to search very hard to find their contact support info since I'm on the free plan. Overall, its working though and I haven't paid a dime yet.

Mailchimp shut down API 1.1, 1.2, and 1.3 - Mailchimp shut down API 1.1, 1.2, and 1.3 and DIDN'T even bother to update THEIR own app for this change. No longer syncs.

Don't know what i'd do w/o Mailchimp - Mailchimp has been incredible. From creating emails campaigns, to newsletter sign-ups, and even abandon cart emails, there are so many features that Mailchimp provides that has helped my business grow, increase sales, and generate more revenue. Customer service has been helpful when I need it. The best part about Mailchimp is how easy it is to use and it syncs with your store automatically. Seriously, Mailchimp is one of the best resources to grow your business and increase sales.

Not great - What happened to testing apps before you start charging people for them? I feel like so many companies just start pushing out their "new and shiny" features and yet half the time they don't work. The abandoned cart emails don't send - at least for me they don't. I was passed on to "premium support" and after a lot of time spent, was told that 'I guess it doesn't work, but we'll look into it'. Many of my customer emails are getting unsubscribed when they don't want them to. You can't actually use the order confirmation emails. That is technically Big Commerce's fault since they won't let you opt out of their hideous order confirmation emails - so customers would end up receiving two. I'm not sure if I'd trust them to send out via MC anyway. Support for MailChimp is mediocre and only via chat. I'm paying more for my email marketing app than I do for my website and half the "bells and whistles" don't even work.

Horrible!! - I can no longer make a landing page for my own website unless I pay $99 a year. Sorry, I'm not doing this! Things have changed and not for the better with this company

Blank screen - I love Mailchimp. On WooCommerce the integration was a bit sketchy, but it worked. This app doesn't seem to do anything. I click on it and just get a blank screen.

Is it working? I can't tell. - I have had mailchimp installed but I'm not even sure that it has any use and am too afraid to remove it incase it messes up my Privy popup. When people sign up to my newsletter using the automatic sign up form in my theme, Mailchimp aren't accounting for these. My Privy popup form is the only thing that links my subscribers to my Mailchimp. I'm finding myself unsure.

No tracking number in ship notification - This 'integration' features a ship notification with...get this...no tracking number! That is the one single piece of information a webstore must include in a ship confirmation email, and this software can not s support that.

Never worked - This has never worked. Had a "connected" site since December 2017 but never showed a list. Never sync'd with BigCommerce. Never could validate the last script for the footer. The only reason left to think why this doesn't work anymore for so long is these issues are purposeful...

Nice Idea. Doesn't Work - I have used MailChimp for several years as a paid subscription outside of BC and really liked it. Tried the app thinking it would fit my need for abandoned carts and remarketing, but it did not. I have spend countless hours creating the emails, connecting and reconnecting at least four times and no luck. Also, coupon codes do not feed over unless you disconnect and reconnect, which, if you get it to work MC says you loose all your data. Moving on.

Doesn't Work! - Integration install STILL does not work. Looks like it's been this way for months. Will be looking for something else now.

Nice integration; decent product, but not for everyone - Nice integration with our BigCommerce store, complete with popups and followup emails. It might even meet all your customer management needs! The contact list is as detailed as your smart phone's contacts, and also tracks spending, dates, and more.Until recently (Aug 2018) MailChimp just kept getting better over the years. We loved the free option, and finally upgraded for tech support. Unfortunately, in a recent platform upgrade, list management became overly complicated and and integration is a little buggy...UPDATE Nov 2020: In trying to be all things to all people, Mailchimp has dropped the ball. There are frequent issues with syncing, and it's just overly complicated. We would prefer a cheaper service with less features.

Run away! Doesn't work with BigCommerce - Since switching to MailChimp 1 month ago, we've been plagued by this issue where anyone who orders from our store gets UNSUBSCRIBED via Admin Action. Neither BigCommerce nor MailChimp can help us resolve this. MailChimp support said they are aware of the issue and developers are working on it. They gave us two months free service. Our developer's never heard of this issue. I can't get anyone on their awful chat/email support to escalate this and call me to find a resolution. I've documented this happening until I'm blue in the face and I just sit here every day watching a 5K mailing list erode away. This is the worst customer experience I've ever had. Run away and don't be lured in by their cheaper prices and advertised features. I mean if you can't even keep a simple mailing list accurately you have no business being in business.
