MailChimp API 3.0 for OSCommerce

MailChimp™ is a leader in HTML Email Marketing. They have clients like Canon, Firefox, General Motors and Intel and they comply with all the SPAM regulations. Emails sent using MailChimp can be personalised and will look much better than ones you could make yourself.

Graith Internet have integrated MailChimp with OSCommerce so that when your customer creates an account (for the checkout process), if they tick the Newsletter box, their first name, last name and email address are automatcially sent to your MailChimp mailing list using the MailChimp API.

If they edit their account and unsubscribe, that cancellation is automatically sent to MailChimp too so you'll automatically have an up-to-date list of people who are happy to receive email marketing material from you.

Once you've exported the customer list that are already subscribed to your mailing list, the Mailchimp database will never be out of date.


Click Buy Now to purchase the addon to install onto your site. It's fairly simple to install and configure and was written with instructions for OSC 2.3.3, MS2.2 RC2 and CRELoaded 6.4 CE (the free version). OSCMax is sufficiently similar to CRE Loaded to use those instructions.

It's been updated to use v3.0 of the MailChimp API and doesn't need phpMyAdmin to install the configuration settings.


The process isn't automatic. You'll be sent an email by a real person and you can converse by email if you have problems or questions. (Please allow extra time if ordering in the evening or weekend (UK time - currently 05:28am). There is no guarantee given about when the work can be done, but if you're unhappy, you'll get a refund.)


If I purchase this & am not able to get it working, is there any recourse? The reason I ask is because our store is heavily modified.

I'd be surprised if the modifications affect where you need to put this code. I've done lots of modifications to OSCommerce and typically, they're not in the customer account area. If by any chance you can't get it going, you can pay the second option and have me install it for you. You can either start with that option or send me the paypal difference if you don't manage.

Hi, I am wondering if your OsCommerce/MailChimp add-on will work with CreLoaded 6.4 B2B??

Yes, the B2B version is no different from 6.4 CE in regard to the files needing to be modified.

Is MailChimp/osC compatible with osC v2.2 RC2a as well?

Yes. There's separate instructions for installation of ms2_2RC2.

It's been a week since I bought this addon off you and I haven't heard anything. The email from us has probably been sent to a different email address.

Check the email address registered with Paypal. It'd be very unusual for you not to have heard from us within a day or so.

Everything is up & working. The only thing I am unclear of is whether this will this sync our newsletter subscribers in real-time, or if I have to upload the exported customer list to mailchimp manually.

New customers will get updated automatically. Existing customers must be uploaded manually once using the admin download page provided, but if your list is new you won't have to do that. New Subscriptions aren't quite instant as they aren't added to the list until Mailchimp have confirmed their acceptance by sending an email and getting them to click a link.

Contact Us if you'd like to integrate MailChimp any other PHP site.
