Our company emails are still marking as Spam in Hotmail/Gmail.

Hi,

We have been using Zoho mail in our company for years. We send out 2-3 times a year with Zoho campaigns.
All our settings such as DNS, DKIM, SPF, DMark are OK.
I don't see ourselves being blacklisted.
Our spamscore tests all show 10/10.

But when we send to Hotmail or Gmail, we are still thrown into the Spam/Junk folder.
Please advise.

Best regards
Emre
