If you're using Zoho CRM to send emails, whether that's individual emails, workflow-triggered emails, or mass emails, it's worth understanding what your email credibility is, since it directly affects whether your messages reach the inbox or get filtered as spam.
Email credibility is a measure of reputation that internet service providers assign to incoming email, based on the sending IP address, to decide whether it's trustworthy enough to deliver to the inbox rather than spam. Because Zoho CRM shares sending infrastructure across many organisations, one organisation's poor sending practices can hurt deliverability for others using the same infrastructure, which is exactly why Zoho monitors and reports on this.
Available to administrators on all paid editions, under Setup, then Emails, then Email Deliverability, then the Email Credibility tab, this dashboard gives your organisation a credibility score from 1 to 100 based on bounce volume and spam complaints, with a score above 70 generally considered good. It also recommends specific actions to help you improve a poor score.
Zoho's own recommendations include making unsubscribe links clearly visible and completable in one click, to reduce spam complaints, and regularly cleaning bounced addresses out of your sending lists rather than repeatedly emailing addresses that keep bouncing.
