Sending newsletters from domain that uses gsuite mail server

Hi, so I’m having a hard toime figuring this out. I want to use mailpoet to send from [email protected] but analogclassics.com uses a gsuite mail server so when i use the mailpoet sending service (or gsuite) the email are thought to be spoofed by mail clients. How can i fix this? I added an include spf record for the mailpoet sending service but that did not help. thanks
