There is something more serious than migration and price increase. By migrating to mailchimp you are agreeing to mailchimp&#x27;s terms and service. If I understand it correctly, now they can read all your customers&#x27; email address and content (presumably for machine learning &amp; send optimization). This is in direct conflict with the agreement we signed with our customers on data sharing. Unless I am mistaken, this seems to be deliberately omitted in mandrill communication to mislead and collect data to create &quot;network effect&quot; from our customer data.
