Too often overlooked, it nevertheless plays a central role in <strong>shipping reputation<\/strong>, the <strong>deliverability<\/strong> messages, and the <strong>recipient confidence<\/strong>.

It is usually the domain visible in the sender's address (e.g.: <code>news@votresite.com<\/code>) and in the technical message headers.<\/p>\n<p><!-- \/wp:paragraph --><!-- wp:paragraph --><\/p>\n<p>It allows email services (Gmail, Outlook, Yahoo, etc.) to identify the origin of emails and verify if you are authorized to send emails from that domain.
