Zoho Mail Addresses for Whitelisting
To whitelist Zoho Mail's IP addresses for ensuring email deliverability, you can add the following IP ranges to your recipient server's allowlist. These IPs are used by Zoho Mail for sending emails (as of Jan 2025):- 8.39.54.0/23
- 204.141.42.0/23
- 136.143.190.0/23
- 136.143.187.0/24
- 65.154.166.0/24
- 8.45.169.0/24
- 8.40.222.0/23
- 216.52.72.0/23
These ranges cover Zoho Mail's outgoing servers and should be sufficient to ensure proper email delivery when added to your allowlist or firewall rules.
Additionally, ensure that your domain's SPF, DKIM, and DMARC records are correctly configured to further improve email deliverability and avoid being flagged as spam by recipient servers
