Problem in getting emails to recipient's inbox

I am facing problem in getting my emails to recipient's inbox to those who have Gmail or qq.com email.
My dkin and spf are properly updated in DNS RECORDS. Its a huge inconvenience and solution provided by zohomail support is to ask recipient to add my email as NOT A SPAM.. which is kinda unprofessional.. this is not why we have chosen Zoho over any other webmail. Do fix it asap
