Our welcome email sent to new users using Apple private relay ends up in Gmail spam folder. The same email sent to users directly isn't classified by Gmail as spam - so it's not the email content that causes Gmail to mark is as junk.
Our domain SPF / DKIM configuration is correct - the emails don't bounce at Apple's relay, they are delivered to users inboxes. The problem is with Gmail seeing them as spam.
Is there any explanation why Gmail could treat the emails as spam? Is there anything we could configure on our side?
