Emails blocked to gmail domain

HI Guys,
hopefully someone will have come across this. all emials from our corporate domain are rejected as spam by Gmail and any domain that uses Gmail. All our DMARC SPF and DKIM shows to be ok, everyting worked fine untik 48 hours ago. Mails to all other domains are sent without issue and we can send mails from gmail accounts into the business. A support call with Microsoft didn’t reveal anything obvious. Any one have any ideas as to why this is happening?

Cloudflare has no involvement in sending outbound email. This is not something the Cloudflare community can help you with. I recommend the dmarcian forum for discussion of email authentication as it relates to message delivery.

no probs - it was worth a try, many thanks for the reply.
