Understanding the Issue

The error message ‘We can’t send this email because the following recipients opted out of receiving email’ typically indicates a consent issue, where the recipient has opted out of receiving emails. However, in this case, the recipient is a Salesforce user, not a contact or lead with consent records, which suggests that the issue lies elsewhere.

The root cause of this issue is the lack of domain authentication in the sandbox environment. When a domain is not authenticated, Salesforce Marketing Cloud cannot verify the sender’s identity, leading to consent-related errors.

Resolving the Issue

To resolve this issue, teams need to authenticate their sending domain in the sandbox environment. This involves setting up domain authentication, which verifies the sender’s identity and ensures that emails are sent from a trusted source.

Domain Authentication Setup

// Example code for setting up domain authentication
// Note: This is a high-level example and may require additional configuration
SET @domain = 'yourdomain.com'
SET @authType = 'DKIM'
// Configure domain authentication settings

Once domain authentication is set up, teams can re-test email verification to ensure that emails are being sent successfully.

Best Practices

To avoid similar issues in the future, teams should ensure that their sending domain is authenticated in all environments, including sandboxes.
