SMTP relay operation

Visit SMTP relay operation is based on a simple but essential principle: it acts as an intermediary between your sending system (emailing software, application server or API) and the recipients' mail servers. In concrete terms, when you trigger an e-mail, your sending server forwards the message to the recipient's mail server. SMTP relay server, which then routes it to the receiving servers (Gmail, Outlook, Yahoo, etc.). This relay checks several key elements in real time - sender authenticity, header conformity, IP address reputation and security rules - to ensure that the message complies with the standards of the e-mail providers. Thanks to this intermediary step, your e-mails benefit from optimized processing: unsuccessful forwarding attempts, queue management, and the application of authentication protocols such as SPF, DKIM and DMARC are taken care of automatically, significantly increasing the deliverability and the security of your communications...

How authentication directly impacts deliverability

Protocols SPF, DKIM and DMARC standards, and configure SMTP relay servers to enable e-mail providers to identify your mail as legitimate. Incorrect configuration or a complete lack of authentication immediately reduces your chances of reaching the inbox, and can trigger spam filters at Gmail, Outlook, Orange or Yahoo.
