Thank you for reaching out! It can take some time to adjust to navigating through the new interface. Below I have some screenshots of how to get to your email campaigns. I hope this is helpful to you and please let us know if you have any questions.
1. Clink on Campaigns in the upper left-hand side
2. Your email campaigns are now found in one of two places:
Campaigns > Activity Type > Newsletters & Announcements or Campaigns > Status > Sent or Draft.
