We are rolling out an Email Credibility dashboard to help CRM administrators monitor the email sending practices of their organisation, and to help them implement domain authentication and email sending measures. Administrators can track spam complaints and bounce rates, while also making changes to their email sending setup by adopting Zoho CRM's recommendations.

Once this feature is made public, this Email Credibility dashboard will be available to administrators in all Zoho CRM paid editions, under Setup > Emails > Email Deliverability, in the Email Credibility tab. Through this dashboard, Zoho CRM will create an Email Credibility Score for each organisation, based on their sending practices, and will recommend actions administrators need to take in order to improve their scores.
The credibility score is a numerical value set on a scale of 1 to 100, where any score above 70 is considered a good score.
The following are score ranges, for reference:
