Readmore in Mailchimp Integration

I have set up an integration with Mail Chimp and it works well. When I publish a new post Mailchimp sends it to my list. So far so good. On my last post I included a read more so that readers would click on the link and go to the website. Mailchimp rendered the read more "View Post". I'd like to have it read "Read More" or something else. Where do I edit this? Is this a feature of easyblog, Joomla, or Mailchimp?
