Email Delivery
Send large volumes of transactional and promotional emails via the SMTP protocol with correct and guaranteed SPF DKIM and DMARC alignment.
The SMTP service for sending large volumes of email
When sending email messages is part of a business process, reliability is not a detail: every message must be delivered quickly, without ending up in spam.
Email Delivery is Qboxmail’s SMTP relay service designed for the secure and high-performance sending of transactional emails (order confirmations, password recovery, internal monitoring…) and promotional emails (newsletters), from any application or platform.
Companies, developers, and professionals can continue using their usual tools (e-commerce platforms, CRMs, management software, or email marketing software) by simply connecting them to a reliable SMTP server built to handle large sending volumes.
Behind the scenes, a robust and optimized infrastructure works to ensure the best possible deliverability.
Email Delivery is designed for:
- Web Agencies managing newsletters and operational communications for their clients
- E-commerce and logistic companies sending order confirmations, promotions, and shipping notifications
- Marketers running promotional campaigns and newsletters through dedicated platforms
- Developers who want to easily integrate a reliable SMTP system into their software
- System Integrators managing automatic email sending from management systems, printers, and business applications
- Management and monitoring systems with automated email sending features
We guarantee the best deliverability in four steps:
Vetting
We apply strict selection of customers and senders to ensure security and integrity of service.
Double DKIM Signature
All email messages sent have a double DKIM signature to ensure that the sender’s reputation is independent of that of other platform users.
Sending Pool Intelligence
Senders are grouped into sending pools in which other senders with the same level of reputation and message quality participate.
DMARC Enforcement
We guarantee and force a correct alignment of SPF, DKIM and From to meet the DMARC requirements of the major mailbox providers.
Vetting
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.

FAQ
Transactional emails are sent to a specific recipient to confirm an action or notify an event, such as order confirmations, sending invoices, password recovery.
Promotional emails are mass emails sent to many recipients for marketing purposes, such as promotional, sales or newsletter email campaigns.
Every user must indicate the message type they intend to send upon registration.
This is crucial for our algorithm, which optimises sending by assigning the appropriate pool and calculating your reputation.
Generally, no, unless your account experiences an elevated rate of bounces or complaints, which may result in the imposition of a daily sending limit.
Using a dedicated IP assigned to a client, regardless of their sending volume and frequency, often creates more problems than it solves. This is because anti-spam systems expect to see a consistent outgoing message volume from an IP address. A low sending volume or activity limited to occasional spikes can make an IP appear suspicious.
If your company sends sufficient and consistent email volumes over time, we offer dedicated IP pools to help improve your reputation.
