Sender Authorization

Sender Authorization Protect your messages and boost their credibility

Every new account in the EmailLabs system is automatically assigned a sandbox domain. This mechanism becomes active following full account verification by the Support Team. The activation process takes place after completing your company details and filling out a short survey regarding the nature of your planned sending activity. This solution enables you to run tests in a production environment without having to wait for your own DNS records to be deployed.

However, to ultimately protect your account against unauthorized sending and ensure a high sender reputation, full authorization of your own sending domain is required. This process allows you to cryptographically sign messages with a DKIM key and configure additional security standards, such as a dedicated Return Path, Whitelabel for links, and a DMARC policy.
