fishing warnings from gmail on zoho creator hosted apps

Hi, we are getting fishing warnings from gmail on the zoho creator domain. Other zoho services such as marketing automation are aware of this and offer workarounds. When will creator allow us to use a custom domain so we are not impacted by free (and maybe spammy) users of creator. We are a paid user. Others should be aware. Seems to me that CNAME custom domain that we can whitelist using SPF/DKIM (that is supported by most zoho apps) would resolve this.
