Do you send unsolicited mail that customers didn't specifically sign up for?

I get so much of this, I sign up for a service to check it out, decide it's not actually a good fit for me but in the process of signing up the company added my email to loads of mailing lists like product updates, advertising, policy changes, etc. etc.

The company doesn't see this as spam. However, it is spam and whenever I receive any of this mail, whether there's a (legally required) unsubscribe link or not, I always mark it as spam.

Don't send email to people unless they specifically ask you to send it. Mailing lists must be opt-in, not opt-out. Otherwise they are spam.

If this is why your mails are being flagged as spam then I agree with Google here. If it's another reason then you have my sympathy.

I agree mails should be opt in (we do it that way). We send some transactional emails such as forget password, purchase receipts, and welcome email.

We already had a good domain reputation, that's why the situation is so difficult to fix.

Do users have to verify their email address to get onto your lists?

I get mail from lots of real businesses, but I never engaged with them, so they're marked as spam.
