Premium SMTP relays for high deliverability
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 Megamail 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.
This is the total number of messages (recipients) you can send to per-day / per-hour / per-minute. Each message can have up to a maximum of 20 recipients, please note that each recipient is counted as a single message towards quota calculation. That is, 20 messages to 1 recipient each are counted as 20 messages, while 1 message to 20 recipients is also counted as 20 messages.
To send without rate-limiting on dedicated mailservers, Premium relay can be turned off (may affect deliverability) on request. Please note that two-factor authentication (2FA) is mandatory for MailUser accounts (email accounts) if Premium relay is disabled. The system disables a MailUser if 2FA is disabled for 3 consecutive days.
