Does Metorik integrate with Mailchimp?
While we don't integrate with Mailchimp, we do offer our own emailing service (which we think is pretty neat) - Metorik Engage.
And if you have your heart set on bulk emailing, we have some good news for you. We plan to introduce a bulk marketing email feature to Metorik, which will allow you to send an email to any order/customer/subscription segment.
In the meantime, if you want to send bulk emails with Mailchimp (or any other bulk email service) to your Metorik custom segments, you can export the email list from Metorik, and then import it into Mailchimp.
