Migrated to O365. Emails going to GMAIL Spam.
You can try checking the headers of one such email which ended up in the spam. Maybe you will find some indication (a header added by Google) why it was marked as spam. You can also try opening a support ticket with MS, but i suspect they will tell you that everything is fine on their end and will suggest to contact Google (which is tough to do). I have found such form to fill https://support.google.com/mail/contact/msgdelivery Maybe it will work.
Just guessing. But a few weeks ago we were getting a lot of phishing emails from bogus addresses, but emails were actually sent from MS servers (someone hacked outlook.com/office 365 mailboxes). If a lot of spam is sent through such Exchange Online server, then i think it can be blacklisted. Though in such case emails probably shouldn't even reach mailboxes.
Hi Griffe,
I've seen a lot of instances and complaints like you have mentioned.
Business emails landing in Spam.
There are few things to be done in order to solve the above given problem:
- Include all the domains and IP's which are allowed to send emails on behalf of your main policy domain in your SPF record.
- Ensure the DKIM keys are getting signed and verified properly for the main policy domain.
- Make sure that the domains associated and used in the Email headers, pre-headers, email body content, URL used in email are NOT blacklisted at any DNSBL or RBL's worldwide like Spamhaus, SpamCop, Baracuda, Talos, etc.
- Make sure the sending IP's are NOT blacklisted at any of the DNS RBL's worldwide.
- And finally ensure that the DMARC policy is set correctly. If you are 100% sure about monitoring then you must go ahead to quarantine and reject policies ASAP. Quarantine and Reject policies are double edged sword. If you don't know what you are doing then you are going to hamper the email deliverability even worse than earlier.
Hope that helps.
Thanks.
