  • Enterprise email - Dedicated plans can choose to enable Premium relay with the 'Premium Relay' addon for $99/yr.
Are there any restrictions on use or sending limits for Premium Relay?
Yes, to protect the infrastructure (from spammers, compromised users, runaway scripts, etc.) and to provide optimum service at all times.

Restrictions on use: Transmitting bulk emails or commercial emails including marketing emails and newsletters.

Since Mailcheap provides unlimited users & domains with all plans, there is no single upper limit for sending but instead a per-user and per-domain sending limit applied daily, hourly and per minute.
Sending limit for Premium Relay
  • Daily: Per domain = 2500 ; Per user = 200
  • Hourly: Per domain = 500 ; Per user = 50
  • Minute: Per domain = 100 ; Per user = 10

This is the total number of messages you can send per-day/per-hour/per-minute. Each message can have up to 10-15 recipients.


Sending without rate-limiting

To send without rate-limiting on dedicated mailservers, Premium relay can be turned off (may affect deliverability) on request.
