Mail Policy and Limits

Shared and Reseller Plans Mail Limits - cPanel

500 per Hour Outgoing Email Limit

This policy is applicable on a per-domain basis on all Shared and Reseller servers, meaning that each addon and subdomain gets its own separate 500 outgoing emails per hour limit. This also applies to mailing lists. If a user sends over 500 emails at any hour, the emails will fail and may bounce back with an undeliverable error.
