Qualified senders only

The Vetting phase involves a strict control of customers and senders accessing the sending of messages so that only trusted companies are granted access and use of the service. In this way, the integrity and security of the service is maintained.

This admission procedure creates a network of trusted customers, preventing the entry of senders who might send unwanted messages.

The screening of new customers is the first essential step in ensuring the best level of service reputation. In this way we protect existing customers and message recipients from those who might misuse the service and damage the reputation of all involved.

Double DKIM Signature

Your reputation is not influenced by others

All emails sent via our platform are signed with a double DKIM signature as part of our authentication and reputation segmentation process.

The first signature is a standard element for all emails, and indicates to the recipient servers that the messages originate from the Qboxmail infrastructure, immediately guaranteeing a high level of reputation for the messages sent.

The second signature is directly linked to the sender domain, effectively differentiating and protecting the reputation of each sender independently.

Sending Pool Intelligence

Beyond Dedicated IPs

Email messages are sent to recipients from our platform through a series of sending pools. Powered by machine learning, our Sender Intelligence system, dynamically moves senders by grouping them together with other senders with the same level of reputation and message quality.

The traditional approach of using dedicated IPs is obsolete: our system improves email deliverability by intelligently adjusting the allocation of sender domains in different pools based also on volume and sending frequency. The more senders send messages that are welcome and in line with recipients’ expectations, the more Sending Pool Intelligence will reward them by placing them in pools of increasing quality.

DMARC Enforcement

DMARC alignment correct and guaranteed

DMARC Enforcement is our method to always guarantee SPF, DKIM and From correspondence with the sender domain and consequently the correct DMARC alignment as required by the major mailbox providers.

It is important to understand that DMARC alignment is now more crucial than ever as it guarantees the authenticity of the sender. Only domains that send with correct DMARC policies will see their messages reach recipients’ inboxes.
