What issender authentication

If you’re using SendGrid to send emails on behalf of your business or organization, it’s important to ensure that your emails are properly authenticated.

What is Sender Authentication?

Sender authentication is a procedure that allows email service providers (ESPs) to confirm that SendGrid is authorized to send emails on your behalf. This helps to establish a trustworthy sender reputation and increases the likelihood that your emails will be delivered to your recipients’ inboxes rather than their spam folders.

What is Whitelabel?

Formerly known as Whitelabel, Sender Authentication is the term now used to describe this process.

How Does Sender Authentication Work?

Sender Authentication is achieved through a number of methods, including:

  • SPF (Sender Policy Framework)
  • DKIM (DomainKeys Identified Mail)
  • DMARC (Domain-based Message Authentication, Reporting & Conformance)

These methods allow SendGrid to prove to ESPs that it has permission to send emails on your behalf, reducing the likelihood that your emails will be marked as spam or rejected entirely. Configuring these settings can be complex, but it’s an important step in ensuring that your emails are delivered as intended.

Summary

Sender Authentication (formerly known as Whitelabel) is a crucial step in establishing a trustworthy sender reputation and ensuring that your emails are delivered to your recipients’ inboxes. By using methods such as SPF, DKIM, and DMARC, SendGrid can demonstrate to ESPs that it has permission to send emails on your behalf and increase the likelihood of successful email delivery.
