My sent mail flagged as Spam by gmail etc.

My sent mail flagged as Spam by gmail etc.

Hi, I have configured my DNS  TXT to :

Resource record: Domainname.com 
Data - value:  "v=spf1 mx include:zoho.com ~all 
TTL: 86400 
Type: TXT
Priority:0  

And I configured my domain keys:

 Resource record:  name._domainkey.domain.com
TTL: 86400
Type: TXT
Priority:0
Data: Copied from conf.
And pressed Start Auth.

But my mail is still flagged as SPAM and when I wanted to test it with domain keys I got this message: 

UQXXOVXBZDARZINUIXDG@dk.mailradar.com Error, ERROR_CODE :554, ERROR_CODE :5.7.1 Rejecting because message seems to be SPAM. This could be because of spam content or structure, links to spam sites, blacklisted mail server or blacklisted client IP. SA Score: 21.924

What now?!

Best regards,
Nejc
