Interesting, and how does it work with other tools such as mailchimp?

Easy. Download the template from Postcards and import the zip archive to the MC: https://mailchimp.com/help/import-a-custom-html-template/#im...

Soon we will add integration with popular services (mailchimp, hubspot, sendgrid etc), so you can export to the ESP you use it with one click.
