Why are emails marked as spam in Zendesk?
Why are most of my emails being marked as spam in Zendesk?
Emails are often marked as spam due to unhealthy resources in the email headers. These headers might contain domains or IP addresses listed in public blocklists, which are used by email filters to identify spam.
To address this, you can extract the email source from the ticket, download the EML file, and review the IP addresses and domains. Use tools like MXToolbox to check if they are blocklisted. If they are, contact the owner to request removal. Over time, recovering suspended tickets in Zendesk can help train the spam filter to improve its accuracy.
