Zoho IP Addreses to Whitelist for US Clients

For a brief understand of what whitelisting is... Whitelisting is a process of adding approved email addresses or server IP addresses to a "whitelist", which tells the email filtering system to allow these emails to bypass the spam filter and land in your inbox. Whitelisting also helps protect your email communication from being flagged as spam and increases the deliverability rate. This is likely a process document you'll want top share with your IT Support Team.

Please white list the below IP ranges to improve deliverability of email sent through various Zoho Apps by Users in the US Data Center.
