CONDITION RECEIVED EMAIL
This action checks if the user has already received an email.
This module checks if an email was a received by your users. Decide on an already existing message or create a new one with “Create new campaign”. If somebody has already received an email message “We miss you!”, send this person another message after 2 days “Knock, knock! Still haven’t heard from you!”. But, if the person hasn’t received such a message, send the first one. It helps to adjust the email messages based on the previous messages sent
