Email lands to Gmail Span Filter

Email lands to Gmail Span Filter

Our email is setup in ZOHO. Domain name is erpfog.com 

When email is send from this domain to gmail ids, emails are landed in gmail spam folder. Please advise.

This is happening when including domain name in email body. I have added spf entry in dns as 
 
"v=spf1 mx include:zoho.com ~all"
