After you setup the email to send add another action to see if the email is open. you do this by clicking the plus sign under your email and selecting decision
Create a new “segment” and filter it by the tag you used in step 5. Now Mautic will send emails to those that didn’t open the first one. Of course you can repeat the process and add the option to remove the tag when they do open a email…
Thank you both so much! I was not finding the option because I was sending the first e-mail as a segment e-mail. I’ve now changed it to a campaign e-mail and was able to.
