Managing outbound email flow efficiently is essential for companies that send frequent communications.
Qboxmail allows you to control and, when needed, increase your daily sending limits directly from the Control Panel, ensuring smooth and reliable delivery.
Every email provider sets a daily limit for how many messages each account can send.
These limits protect the infrastructure from abuse and help maintain high deliverability rates.
If you regularly send a large number of messages, for example to clients, partners, or employees, you may need to increase your daily limit to avoid interruptions.
Raising your sending limit is useful when you need to deliver time-sensitive communications to many recipients at once.
Typical examples include internal updates, service notifications, or important business announcements.
Higher thresholds allow you to reach everyone without delay while keeping full control of your delivery reputation.
It is important to use this feature responsibly.
Sending too many emails too quickly can trigger spam filters or temporary delivery pauses on the recipient side.
By default, all Qboxmail accounts can send up to 250 emails per day across Basic, Professional, and Enterprise plans.
You can raise this limit according to your needs, up to 5,000 emails per day.
The configuration is available directly from the Control Panel:
Domain → Email Account → General → Sending Limits.
All messages sent through Qboxmail’s SMTP servers are automatically signed with DKIM, ensuring the authenticity and integrity of your communications.
For more details, you can refer to our article about SPF, DKIM, and DMARC authentication.

Qboxmail is designed for professional communication and transactional email delivery, not for newsletter campaigns or mass marketing.
For bulk marketing activities, we recommend using specialized platforms such as MailUp, which are optimized for those purposes.
Increasing your sending limits helps your company maintain efficient communication without delays or interruptions.
It is a flexible feature designed for organizations that value reliability, security, and compliance in every message they send.
