Constant Contact
Posted this in 2012, seeing Mike's post today made me think about resurrecting this. Our mailing list is now on Constant Contact, rather than Mailchimp, but the need remains...
Anybody tried connecting an in-house database to this type of service? seems like it should be relatively straightforward.
Idea is to have a mailchimp database that our website users can subscribe to, and also collect addresses from customers at point of sale. Then have a nightly process to synchronise them.
They publish an API for XML-RPC, PHP and JSON.
I should be on a beach ...
