With this extension you will be able to export a custom hash from Magento to Merge Tag on MailChimp and use as a parameters to logged in your customer on you store, after they click them on e-mail.
This extesion use Magento Crypt to crypt and decrypt the value of the Merge Tag. For those don't knew about it, each Magento installation have a unique phrase used to crypt some data. So "thiagosantos" string crypted using my Magento instalation will have a diferent return string, of doing the same on your own store. This make my extension much secured and very usefull, for AutoLogin.
