MailChimp API 3.0 for OSCommerce
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exported the customer list that are already subscribed to your mailing list, the Mailchimp database will never be out of date.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.
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 11:49am). 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.
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.
